Little blue lines on maps

June started with a bit of a shock. Ex-work colleague Bob had asked me for any lichen records I might have from the ancient aspens on his farm at Easter Tulloch to help with a grant application. Knowing how important these ancient aspen stands are for lichens and other flora and fauna, I offered to write a wee note about this to accompany his application particularly as the grant might pay for fencing to exclude stock grazing and allow trees to regenerate, or for planting new areas. Added to the note I provided a list of lichens “likely” to be present on Bob’s aspens drawing on information on common species that had been recorded by experts in the adjacent aspen woods and from other woods close by. Having recorded the lichen Lobaria pulmonaria on one of Bob’s trees (left), the only location for this species within the Tulloch aspen woods, I also suggested that a full survey by expert lichenologists might reveal other unusual species. Job done, Bob sent in his application, and I thought that would be that. I received an email the following day from the grant aiding body saying that I had been nominated as “lichen expert” for Bob’s farm, something I had to decline by return email explaining that apart from looking for and recording a few rarer lichens, I knew little about all the common species hanging thickly from Bob’s trees! Phew, me a lichen expert, they must have got me mixed up with someone else! I did offer though to help with butterfly recording, if needed.

We had another shock at the start of the month, the temperature, for two whole days, rose to the dizzy heights of 29 degrees C. Just what was needed now that all the Osmia bee nest boxes were installed and waiting for occupants. A walk along one of the Abernethy tracks where there were boxes and where the bee had been recorded in the past, found them visiting bird’s-foot trefoil flowers (right) at three different locations. A great start. A visit to a small lay-by at School Wood in the village (threatened with houses as endorsed by the Cairngorms National Park and housing association) with an abundance of trefoil flowers also found the bee on the wing, the first time it had been seen here since 2001. But that was it, and the following day temperatures dropped by 20 degrees, heralding what was to follow for most of the rest of the month. We even had several night-time frosts down to -2 degrees C! Janet’s flowers in the garden suffered quite badly and a check of a local site for one-flowered wintergreen showed several of the earlier emerging flowers had been browned off. The visit to the wintergreens was also to carryout a bit of habitat management, cutting back some of the ever expanding bushes of rhododendron particularly where the best flowering patch for the plant was being threatened. Getting rid of this ultra-invasive plant really is soul destroying, almost every branch that has grown outwards and is touching the ground, roots, converting a single bush into something quite monstrous, and if you don’t pull every bit up, off it goes again. In the west of Scotland trying to remove this plant is costing millions of pounds, and as you drive around the east of Scotland you can see a time-bomb gathering pace to explode. One of the plants on my most hated list. Searching around the site it was nice to find a single plant, sheltered from grazing sheep by a fallen pine branch, in a location where Janet and myself found it growing about 25 years ago. In another location a group of wintergreens were growing in a flowering patch of twinflower (left), something I’ve not seen anywhere else.

One of the plants on the list of the Cairngorms Rare Plants Project is small cow-wheat (Melampyrum sylvaticum). Andy Scobie is the Project Officer and had mentioned this plant to me whilst helping out with lesser butterfly orchid counts in the area. There are a few extant sites for the plant in the Cairngorms National Park but many more “old” records where it hasn’t been seen for a long time. Many of the old records also have little accurate data regarding exact location so it’s quite difficult to know where to start looking. One of the best ways of knowing where to look is to try and see the plant at one of the known sites and hence we come to the first of “the little blue lines on a map”. The small cow-wheat at some sites seems to like to grow in or close to damp woodland. It is a parasite and has to have its host plant blaeberry/bilberry close at hand. In 2004 it had been recorded from a site close to Inverness “on a grassy area under hazel and birch above and 3 metres from a wee burn with blaeberry and the grass Holcus mollis and bracken”. Little did I know just how valuable that tiny bit of information would be. There was a grid reference but only to an accuracy of 100 metres. The easy bit was finding the little blue line on the map, a small burn running south from the River Nairn. Thankfully I had put my wellies on and was able to walk in or along the burn checking for suitable sites. The first interesting find was sanicle growing at the base of an incised outcrop of conglomerate (a concrete like rock consisting of pebbles and gravel embedded in what looks like cement). The moist site had lots of ferns including the tiny brittle bladder fern. Initially the banks were too steep to match the description and, there was no blaeberry! The first hour of searching failed to find anything and considering I was trying to find a patch of plants one to two metres square, I was beginning to think of failure. A little further up the burn the bank became less steep and the mix of hazel and birch was still present and I decided to concentrate on looking for blaeberry and Holcus mollis rather than the wetter areas I had been searching. A larch tree gave a bit of hope and the first plants of blaeberry but a check of my GPS showed I was now in the wrong 100m OS grid square to the one from the last record. Sparse bracken and some blaeberry under hazels indicated I might be in the right area so I kept looking and it was with great relief that as I climbed up the bank from the burn a cow-wheat plant with tiny flowers came into view (above right). Small egg-yolk yellow flowers a few with a touch of orange and the flowers no longer than the green calyx from which they grew told me that this was the plant I was looking for (compare with common cow-wheat left). Time for a sandwich (just as the heavens opened) and a count of the number of plants, a quick photo before heading for home now knowing what I was looking for elsewhere. This one was easy, now to try and find the plant at Kinrara near Aviemore where the last grid reference from 1890 gives the location to the nearest one-kilometre grid square!

It’s been a bit of a month for trying to re-locate old plant sites. The location of herb paris in the Pass of Ryvoan woodlands has been a bit of a challenge for a few people over the last few years and despite the late Mary McCallum-Webster recording the flower from two locations neither have been found in recent years. I made the pilgrimage mid-month and joined the list of failures but then every cloud has a silver lining and the visit resulted in finding yet another group of ancient willows with the three Lobarian lichens (L. pulmonaria, scrobiculata and amplissima), masses of woodruff and a rare sedge locally wood sedge (Carex sylvatica right). Climbing high into the scree zone gave a great view of the Green Loch – Lochan Uaine. A visit to the same loch a day later was a slightly sadder affair but at the same time a celebration of the life of a neighbour in Nethybridge who had walked and cycled the tracks of Abernethy and Glenmore and who wanted her ashes to be scattered by the loch. She chose a good spot and those present enjoyed the view from the loch to Ryvoan Bothy as they said farewell. The couple of visits to Kinrara have also failed to re-find the small cow-wheat but an erupting willow warbler from my feet revealed a nest full of chicks, the biggest population locally for a rare grass mountain melic (Melica nutans) and false-broom (Brachypodium sylvaticum), oak and beech ferns growing together and masses and masses of common cow-wheat – some with small flowers. The search goes on.

The next “little blue line on the map” to be visited was near Ballindalloch Castle, and was a follow up visit to one made by ex-work colleague Andy where additional woodland needed to be checked for coral-root orchid. During his visit he had found huge numbers of the orchid in a mixture of wet willow/birch woodland where an earlier record had stated that a few plants had been found. I had been visiting this area of the last couple of years looking for this plant but had been looking in the wrong bit of woodland! Dooh! So, the start of the little blue line was located - the small burn that would eventually lead to the area to be checked. I had hardly left the road when the first orchids were found and this was nowhere near where I was supposed to be searching. A good omen. As I worked my way up the burn more small groups of orchids were found and as I approached the area where Andy had concluded his search, larger numbers were found. This orchid is quite beautiful in its own way. It lacks the bright colours, showy flowers and leaves of other orchids and even when the pale yellow flowers are “fresh” they look like they have just gone over (right). The flower doesn’t photosynthesise like most other orchids/flowers having almost no chlorophyll in its make up but relies on the fungi that live in the coral-like lump at the base of its stem for most of its nutrients. Bird’s nest and ghost orchids grow in a similar symbiotic way. The coral-root orchid is also self-pollinating and has no nectar or scent to attract insects. Amazing. I digress. The little blue line eventually gave way to a series of areas of boggy willow woodland and it was within these areas that the majority of orchids were found and our combined total of 400 flowering spikes is probably the largest population known locally, and a bit of additional woodland that I thought have been counted, wasn’t even visited. Beech fern and pale sedge were also new to the site and a group of bird cherrys in the drier woodland were totally covered in spooky webs (left) of the munching army of ermine moth caterpillars (visit http://ukmoths.org.uk/show.php?bf=424 to see it).

An email mid-month lead to me renewing my links to the pinewood hoverfly (Blera fallax) project. PhD research student Ellie had been rearing and releasing adult hoverflies at a location in Abernethy Forest where the fly had been last seen in the 1980s and where larvae had been released in artificial rot-holes the previous autumn (see November 2010 diary). Ellie was having to head south to get on with writing up her thesis and a few adults had yet to emerge before being released and would I like to be foster-dad to any that might emerge? What an opportunity to be involved with this bonny wee fly at the most important part of its life just before it heads off into the wilds of the forest to search for a mate and ensure the next (and first new wild) generation of pine hoverflies continue as part of the forest ecosystem. It took a few days for the first hoverfly to emerge and I found it hanging upside down on white gauze covering the top of the “pot” – actually a white plastic catering cup. Most of the flies emerge first thing in the morning and spend the next few hours “pumping up their body and more importantly, their wings, in preparation for their first flight, best described as the fly swaying gently back and forth whilst trying to pump itself up a bit like a very constipated human on the loo! Then came the tricky bit. Ellie likes to have a record of the biometrics (size of head, body, wings etc) of each fly that emerges and this is achieved by placing the fly on a squared piece of encapsulated paper to have its photo taken (left). The squares on the paper are 5mm in size and from that the fly’s measurements can be deduced. With luck the fly might stay still when on the grid but more often than not they run around or climb up into the wee plastic pot kept close to hand in case the wee beastie tries to take off, so great patience is needed whist waiting for the right moment to release the shutter. Photo taken they are left quiet for an hour or so before being taken to the release site in the forest (right), the first three having to wait for gaps in some fairly wet weather. In all, five hoverflies were released and from the body markings it was noted that 4 were female and 1 was male. We wish them all well and I hope I have played a little part in helping the pine hoverfly to re-establish itself in the forest close to Loch Garten. See

The month ended with a bit of paid work – recording patches of bird’s-foot trefoil along several tracks in Abernethy, a repeat of a survey carried out ten years ago. Locations of patches were recorded along with size and quality/quantity of flowers. Bird’s foot trefoil flowers support a wide range of insects including the wee bee Osmia uncinata which was mentioned in the last diary. As the major management projects have declined (mainly timber felling and extraction) the track verges have received little disturbance and without disturbance, the populations of the plant will decline. The survey found that whilst the plant was found in many of its 2001 haunts, very few of the patches were producing many flowers, and if the track verges are not disturbed a little, the plant is likely to disappear under masses of heather and young pine trees. Watch this space.

It was also the time of year for counting lesser butterfly orchids at two local sites. The field in Tulloch produced just 6 flowering spikes this year and at the other site by the B970 it was obvious that there would be less flowers than the massive count of 2800 in 2010. Once again late frosts had caused many flowers at the main site to keel over (left), along with some of the fragrant orchids, though these would be included in the count. One of the mysteries to be solved in the lesser butterfly orchid world is what insect or insects are responsible for pollinating the flower and to try and answer this question a couple of local moth experts had offered to help the Park’s rare plants officer by running a few moth traps at the site to see if any of the moths trapped had the right “pollinia” attached to their head, eyes or proboscises. To ensure pollination the orchids have developed some pretty novel methods when compared to other flowers which have “free flying” pollen, where the pollen can cross-fertilise nearby flower by wind-borne pollen grains or by the grains being transferred from flower to flower by insects. In orchids all pollination is by insects and to ensure this is carried out successfully the orchids provide the pollinators with a landing pad, the bottom lip of the flower, and “landing lights” ultraviolet guides (invisible to humans) which guide the pollinator towards the orchid’s pollen masses or pollinia. The pollinia (above right photo © Mike Taylor shows 3 types of pollinia) are stored in the flower behind the anther cap (male sexual part of the flower) and as the insects explore the flower the clubbed shaped pollinia (pollen mass) with a sticky pad at its base, glue themselves to the part of the pollinator that comes into contact with them. The insect’s role is then to carry the pollinia to the stigma (female part) of other orchids to ensure fertilisation. The tricky bit would be trying to identify whether the right pollinia was attached to any of the moths trapped, not easy when the trap site had three species of orchids present. Would they even be any pollinia? The moth traps did their job and indeed there were moths with pollinia (The Spectacle moth left) but so far all have been identified as coming from the fragrant orchids. After the traps had been emptied I stayed on at the orchid site to see if I could physically see anything visiting the lesser butterfly orchids. The first “insect” to appear that was interested in any of the orchids was a six-spot burnet moth, but all it (and others later) was interested in was the fragrant orchids and at one flower spike I watched the build-up of pollinia on the moth proboscis (right) as it probed into each flower on the spike. One of the moths from the trap had 20 pollinia attached to its curled up proboscis! The next day was count day but sadly an on-going injury to one of my thigh muscles meant I had to pull out of the count. The count though was completed and this year’s total was 800 lesser butterfly orchids. The summer is flying by far too quickly.

That’s it, enjoy the read.

A hairy and sticky month dominated by wind and homes for bees (we hope)!

During May, Scotland changed, possibly for ever.

In 1998, when the late Donald Dewar oversaw the passage of the Scotland Bill through the Houses of Commons he set up a type of PR voting system which tried to ensure no one party would have an outright majority. For two elections this worked well. But, with inept leaders of the non-SNP parties, poor manifestoes or whatever, this didn’t work on 5 May 2011 and many experienced MSPs lost their seats to leave a majority SNP government in post and seemingly “anything but English” Alex Salmond in charge. With a whacking majority the push for an independent Scotland has started, with every opportunity taken since the election (and despite an independent Scotland not being a part of the election manifesto) to up the anti about perceived national policies that affect Scotland. I would suggest these are dangerous times for Scotland with a lack of experience in parliament and a majority that can allow bills to be steam-rollered through. And the man himself? Not that I would say we have a vain and pompous man in charge of Scotland but if you compare photos that appeared in the press and election leaflets with the non-airbrushed real thing, we have every reason to be worried. With everything now “free” in Scotland perhaps the country will just go bust before the 5 year-term is out. Less time spent pushing the ‘anti-this - anti-that’ agenda and more time governing this great country – Scotland, would be best for everyone.

A good part of the month was spent preparing and installing bee nest boxes with the tiny mason bee Osmia uncinata the target. In other parts of the world nest boxes are used successfully to ensure healthy populations of other Osmia bees used for the purposes of pollinating crops. An earlier trial of laminated type boxes in Abernethy during 2007 failed to attract any bee residents but it is hoped that this design of “box”, proven elsewhere for other bees, might be successful. The current boxes were supplied by the Red Beehive Company (http://redbeehive.coolitshopping.com/dbeehive.coolitshopping.com/ ) and comprise a section of 4” plastic drain pipe filled with cardboard tubes with internal diameters of 6 to 8mm. These are aimed at mimicking the natural long-horn beetle breeding holes found in dead trees within the forest which, once vacated, are used by the bees as their breeding sites. Very few of these natural bee sites have ever been found with Mike Edwards and Andy Davidson the only people I know who have ever seen them and numbering probably no more than 10. We know that the bee feeds heavily on bird’s-foot trefoil but there may also be other important flowers it visits for pollen and nectar and the only way of identifying foraging plants is to check breeding sites for residual pollen grains. Where the bee occurs it is therefore important to ensure enough lightly disturbed ground is available for the trefoil to grow (its preferred habitat) but there could be other important plant populations that need to be considered. If the tubes in the nest boxes are used, this would be a great help in allowing access to pollen which would be analysed for plant identification. In all 100 boxes have been installed at 17 locations where the bee was recorded during my survey in 2007 and at a couple of other sites where Murdo Macdonald has regularly seen it. We now just need a bit of prolonged sunshine during June (the bee needs temperatures of more than 16 deg C) and for the wee bee to find one or more boxes to its liking. In addition, I have drilled out a few Scots pine logs (right) with 6, 8 and 10mm holes and installed these to see if they might also be to the bees liking.

Installing the boxes had the added benefit of visiting a few locations where I hadn’t been for a while, including parts of the Forestry Commissions forest at Inshriach, Bognacruie at Abernethy and the wonderfully boggy woodland at Monadh Mor north of Inverness. The last run was to Culbin Forest near Forres. A singing whitethroat was the only bonus on a wet and windy day at Inshriach, and I witnessed an insect expert in action when I was joined by Murdo Macdonald at Monadh Mor where we saw our first white-faced darter dragonfly (Leucorrhinia dubia) for the year. The visit to Culbin was different as the bee was found here by the late Gill Nisbet and I had to spend quite a bit of time looking for the best stands of bird’s-foot trefoil before installing the boxes. One wander took me towards a boggy bit of land in an ex-quarry where an unusual clubmoss – Lycopodium inundatum the marsh clubmoss grows. A wee detour and I was in the quarry and there, creeping across the wet gravel, were lots of new shoots of the clubmoss (left). Culbin never fails to amaze me. Here we have a mainly conifer wood growing on former sand dunes but with nearly all the rarer pinewood plants present, and here in a fairly recently worked quarry, one of our rarer clubmosses. How did it and all the other plants get there? Amazing. After installing bee boxes near Loch a’ Chnuic in Abernethy a walk up one of the wee burns took me close to the highest sand martin colony I know of locally at 440m above sea level, and with about 20 holes (right) the birds seem to be doing quite well.

Nearer to home Loch Morlich on the way to Cairngorm used to be a site locally for the clubmoss but having made several visits to the shores of the loch, I hadn’t managed to re-find it. Inspired by how easy the bright green new growth at Culbin was to see, I thought another visit to Morlich might pay dividends so a couple of evenings later I made my way to the loch. Nothing could be found in the boggy hollow between the road and the loch so I paddled my way across the loch’s outflow and searched the shore and adjacent boggy bits. The first thing that caught my eye was long-leaved sundew (left Drosera anglica), quite a good population right on the shore. This a fairly rare plant in our area. In fact as I walked along there were quite a few small clumps of this plant but not a sign of the clubmoss. An egg floating in the water looked like goldeneye or goosander – both were present on the loch, as was a distant wailing red-throated diver. In one boggy area a nice patch of flowering cranberry (Vaccinium oxycoccus) but just too dark to get a decent photo. As I pushed my way through a few stunted bog-pines I found quite an amazing bog with a slight flow of water. On most of the wee “islands” I could see lots and lots of long-leaved sundew, perhaps the mother and father of those plants on the loch shore. However, some groups of sundews looked a little bit different, the leaves were neither as round and prostrate as the plentiful round-leaved sundew, but neither were they tall, and a bit curled, like the long-leaved plants, the leaves were best described as “paddle” shaped (right). Being early in the growing season I thought I was just looking at young plants of the long-leaved sundew but just in case I carefully removed one and popped it into my container for checking. All around the sticky leaves had plenty of insect “food” attached to them – hence their collective name as insectivorous plants (see http://en.wikipedia.org/wiki/Carnivorous_plant for a description). It should really have been pretty obvious, growing side by side were round-leaved and long-leaved sundews and in between was a perfect hybrid called Drosera x obovata (right) named as “Ivan’s Paddle”, and it had even been recorded from this area in 1956. 1956! I think the keen botanists need to get out a bit more.

So, as is usual with me I wondered if the one known site in Abernethy with both sundews present, might also have Ivan’s Paddle amongst them. The hybrid plants found weren’t as big and bold as the Morlich ones, but the paddle shape was obvious so a new species was added to the RSPB list. Anywhere else? A check with BSBI colleague Andy produced another couple of local sites where long-leaved sundews had been recorded in the past and usually if the rarer one is present the common round-leaved should also be there. I failed to find anything at one site but the other site, in the hills above Aviemore, turned up all three species along with a pair of nesting greylag geese, a few flimsy flowering spikes of alpine meadow rue and the rare moss Dicranum bergerii, though a group of Bryologists had found this moss in the same general area a few years earlier. So you know what the moral of this tale is – remember to look for Ivan if you see the other two species present. The photo above should help you with L to R, long-leaved, round-leaved and Ivan’s Paddle (D x obovata).

Installing the bee boxes also had another major spin-off. As a trial I put up 5 boxes at one of the Osmia sites close to the Speyside Way in Abernethy Forest. Job complete I walked a few adjacent tracks to see if there were any good patches of bird’s-foot trefoil where another group of boxes could be installed. Along the side of one track were large mounds of spoil left over from the time the track was installed about 10 years ago and they looked like they could provide a home for brown shield-moss capsules (Buxbaumia aphylla). Sure enough, there were a couple of capsules on one mound and a few more on the next, quite a find I was thinking. Compared to the major finds of the rarer green shield-moss, few brown shield-moss capsules have been found in recent years, so I was feeling quite pleased with myself. A few hundred metres along the track and the verge itself also looked suitable and as I looked down I first saw a dozen capsules (left), then a few more, and a few more. A quick count gave a figure of around 150 capsules, something probably unheard of in the UK. I returned a couple of days later with pegs and tapes to do a “proper” count and thankfully, a hand tally counter because after a couple of hours of bent over counting the track had revealed it was home to 680 capsules, definitely unheard of before in the UK.

Just as the last of the bee boxes was installed (20th to 23rd) we had lying snow down to 1500’, sleet on the A9 and winds of over 100 miles per hour on the summit of Cairngorm. What happened to the hot weather we enjoyed in April? This change to cool, windy weather made for poor results from the butterfly transect after such a promising start to the season, and the weekly weather forecast had to be studied quite a bit to ensure some of the ongoing bird surveys could be carried out in reasonable conditions. Not ideal. The second round of visits were made to the BTO breeding bird survey squares with little to report apart from more flowering cranberry (right) but in the dawn daylight this time. I also accepted a request to undertake a farm bird survey (mainly waders + other key species) for a local farmer needing breeding bird information for a grant application he was making. “Within an hour of dawn….” states the survey rules, and with 3 visits to be made, each start time got progressively earlier. The farm is in a known good wader area so the possibility of good numbers of breeding lapwings, oystercatchers and curlews was appealing. Wrong! The farm comprises a mix of stock, crop and heathery bog totalling more than 100ha. All three species are present but with just 1 family of lapwings, 1 family of oystercatchers + 1 on eggs and possibly 1 family of curlews, this is nothing less than a disaster. There should be dozens of successful waders in this area but something dramatic is or has happened and even the farmer is wondering where his birds have gone to. Personally I think we are seeing the results from a slow but progressive change from wader friendly farming to the modern mono-crop system and despite the farmer saying we are not doing any different crop rotations now to 20 years ago, subtly I think lots of things have changed. Someone needs to really get to the bottom of what is happening otherwise the loss of ALL the skylarks (do you remember them?) over the last 20 years will be followed very shortly by all the waders. A ‘Silent Spring’ is not that far away and no-one seems to care. The big problem is that the folk who know what is happening are those who walk the miles and see and record things, the folk who are trying to “address” the issue tap out tales of woe on their PC’s from within their offices. Sorry, but it is depressing.

Despite the weather there are lots of family parties of birds in the forests locally, 3 families of crested tits on one outing last week along with all the coal tits and treecreepers, and around the house blue and great tits and the family of robins from next to the chalet. After a depressing meeting about houses planned for School Wood in the village, I hopped on my bike and pedalled onto the Dorback Estate to re-visit the area close to the Bridge of Brown lime-kiln in the last Diary. This is my third visit to the area in the last few weeks to try and find a plant that hasn’t been seen at its previously known locations for 15 years, and if you take into account records in the wider area, 30 to 50 years. Most of these older records didn’t have the benefit of modern GPS recording equipment and are quite often given as 10 kilometre map square locations, or 1 km or 2 km squares, so there can be lots of potential sites to search. The plant is the hairy stonecrop Sedum villosum, and is one that keen botanists locally know of its decline and a few have had a go at finding it. On my last visit I had a pretty good description (at the top of a small waterfall) of where it had been seen by a couple of well known botanists in 1972, but nothing was found. Vegetation local to the site had obvious signs of sheep grazing, so this could be part of the plants demise. It likes to grow on the gravels by small streams or on wet rocks in similar situations, so it’s a case of starting at the bottom end of any running water and them make your way up the hill searching as you go. The bike ride out along the moorland track was quite eerie with very little bird song to be heard. Lapwings had chicks on improved grassland by another lime-kiln and close to where I was going to start my search (the waterfall again) there was a very noisy curlew with chicks. Thankfully it got used to me and quietened down. Again, nothing at the small waterfall site nor in the next gully with a wee stream, though the moschatel (Town Hall clock above right) from an earlier visit were a bit sheep nibbled. The next wee stream looked really suitable in patches with lots of wet gravel but it was only when I looked closely at something growing from the rock that I though I had found what I was looking for (left). The plant was certainly a stonecrop with the characteristic “inflated” looking leaves, but to be sure I would need to see if the alternately growing leaves were “glandular-pubescent” meaning that on the tip of each leaf hair there was a tiny drop of liquid (enlarge photo to see). With my hand-lens this feature was confirmed and amazingly, hidden under a tiny rock outcrop was a single stem of hairy stonecrop. Phew! Being a single plant I couldn’t remove anything so my evidence would have to be obtained through my camera lens – thankfully I had brought the bigger D80 + macro lense with me rather than the infuriating compact with its hit and miss method of focusing. I had to lean against and sit on wet rock to get the photo but to hell, what’s a wet bum after 15 years! And that was it, further searches of streams and runnels yielded nothing, so the current population remains at a single plant - still a bit more searching to do.

That’s it until after the longest day, enjoy the read.

A marathon month sealed with THAT KISS

Why is grandson Finlay running?

I managed to fill the garage with sawdust at the start of the month as I set about converting all the reasonable sized pieces of stacked wood, some from house building time no less, into inch by half inch strips of wood to make up into trellises. The original trellis work by the chalet had seen better days and it was time for replacements. Sawing the wood was the easy bit. I then used one of the old sections of trellis as a template and proceeded to screw the framework together. Of course I ran out of screws after the first couple of trellises as there were so many needed to secure all the joints. And then came the fun bit – painting the damn things. Round and round each square, talk about watching paint dry, with two coats it took about four hours for each one. However, by month’s end all were completed and installed; I just hope the squirrels and visiting birds appreciate what has been done for them!

Cos’ grandma’s chasing him!

To break the trellis marathon I made a dash one afternoon to a wee waterfall by the B9007 road from Carrbridge to Ferness, not visible from the road, but a gem with a nice stand of aspens, willows and birch trees. As I left the road I came upon a carcass of probably a dead mountain hare, part of which was covered in the most amazing growth of moss. Somewhere, in the back of my mind, I remembered that a moss, now thought to be extinct, was last found growing on the carcass of a dead sheep (sorry about the gore) in the hills near Newtonmore and I just thought there might be a chance that this could be it. So tiny leaves were removed and set up on a slide for checking under the microscope but try as I might, I couldn’t quite find the correct features for the long lost moss. Just to be sure, a piece was sent to the UK expert on these mosses and the reply confirmed what I had thought and the moss turned out to be my old favourite from last summer, Tetraplodon mnioides the slender cruet moss. At this early stage of the season the moss lacked the characteristic red colours found later in the year with the end result that the search for the carrion moss – Aplodon wormskioldi, continues.

And then it was off to Lancashire to visit Janet’s mum (91) and family and to sample the delights of pub lunches in the nearby Ribble Valley (right). A visit to Worston produced the first willow warbler, chiffchaff and blackcap of the year, all of which seemed to follow us back up the road to Scotland. I never fail to be impressed by the fossil filled stones which make up many of the farm field walls in this area and outcrops of the same rock forming the rounded hills all around Clitheroe and Downham and one of the reasons that Ribble Cement (now Castle Cement) set up its quarrying operations between the two towns. The carboniferous limestone was created some 300 million years ago by a major marine incursion across Britain hence the abundance of marine fossils such as brachiopods, trilobites and crinoids. The limestone outcrop between Kirby Lonsdale and Silverdale, next to the RSPB Leighton Moss reserve, gives rise to some of the best examples of limestone pavement in the country supporting a wide range of lime-loving plants and insects. But back to the present. The opportunity to spend a couple of hours in this amazing landscape (whilst Janet visited Clitheroe market) was grabbed with both hands and I headed for the outcrop by the Calf’s Head at Worston. A bit early for most flowering plants I was able to make a list of birds for the final breeding season of the BTO Atlas, and to see if any of the unusual lichens of limestone, so rare in Scotland, could be found. A strange black lichen on many of the rocks turned out to be Collema auriforme and on some of the grassy areas between the sheep tracks there the remains of carline thistle. A small plant, just coming into flower and found amongst rocks and on walls was the slightly hairy rue-leaved saxifrage (above left), something new to me and quite a rare plant in Scotland.

The visit inspired me to have a look at some of the lime-rich areas close to home, and though none of them compete with the Ribble Valley outcrops, many are important in their own right, remember the dark red helleborine encounter of last summer. A visit to rocks above the river at Bridge of Brown though not limestone, produced a tiny wee fungus which is also a lichen!? called Lichenomphalina alpine (right) and new to the site along with a wee moss called drumsticks due to its reproductive “gemmae” being borne on a ball at the top of the stalk. For the “real” limestone I made a trip to Invercald on Deeside where it pops out in small sections of crag and large boulders of lime-rich rock sit at the base of the crag. On the walk from the car the first redstart of the year was singing and by the crag a ring ouzel was in fine voice. It was on one of these boulders that the lichen Solorina saccata had been recorded in the past and whilst looking for it I had been told to keep my eyes open for a very unusual puffball! The plants growing at the base of the crag indicated richness with maidenhair spleenwort, hard shield fern and shining cranes-bill to name a few. Gradually the rocky scree gave way to an area of loose, pale gravel which turned out to be the limestone outcrop. And there, by a rock outcrop was a strange greenish lichen with a dark central “eye” the reproductive apothecia, I’d found my Solorina (left) but in a completely new location to that found previously on a nearby rock. As I made my way up the steep gravely slope there was more, and more, growing in nooks and crannies for about one hundred metres. Amazing. But could I find the one growing on the rock? For about an hour I searched but on this occasion failed completely to find the lichen. However, what was the wee round growth on the top of one of the rocks (right)? – the complete but spent body of a tiny white puffball Tulostoma niveum, just the thing I had been advised to keep an eye open for. This had to be the find of the day and though it wasn’t a “fresh” puffball (they appear in September), it had all the features and characteristics as though it was. The puffball was no bigger than a 1 pence piece and it was sitting on top of a huge limestone rock weighing many tons. Currently, this site is one of only three known in the UK, and though it has been found on several rocks at this site it remains a very rare fungus.

On the 10 April the first of this seasons RSPBs butterfly transects was walked, a small tortoiseshell being the only butterfly recorded and on returning home the remainder of last seasons parsnips were lifted. The following day I attended a meeting to discuss the possibility of being involved in an Osmia uncinata (mason bee) nest box project. It is thought that one of the limiting factors in the bees lifecycle is the lack of suitable nest sites which, as far as is known, is the vacated holes, in dead trees, of long-horned beetle larvae. The projects aim is to see whether by providing artificial nest “boxes” the bee can breed more successfully. A nest box comprises a piece of plastic drain pipe, blocked at one end and the pipe filled with small cardboard tubes, 6 – 8mm in diameter. In all, 100 boxes are to be installed at 15 sites where I recorded the bee during a survey in 2007. After the meeting a day was spent sourcing materials to allow the nest boxes to be fixed to suitable trees. The nest boxes are to be delivered by the end of April allowing installation to take place before the bees emerge in early June. Watch this space. Visits to a couple of lime-rich sites produced a new location for (left) purple saxifrage (Inshriach) and moschatel with loads of cowslips (right -Tomintoul) the latter visit re-finding locations for the lichens Lobaria pulmonaria (lungwort) and Peltigera rufescens previously recorded in this area in 1968.

I managed to discuss my limestone searches with near neighbour Donald, a geologist, and a day later an email arrived suggesting I should visit a site by the A939 Lecht ski road where Donald knew (from his geology maps) that over a hundred years ago limestone had been mined to burn in lime kilns before spreading the resultant “quicklime” on the farm fields. The visit didn’t disappoint and after an afternoons search I had found a new site for the Solorina lichen, and new sites for moschatel (left), mare’s tail from a wee lochan, an amazing white scale insect (right) and, in the last juniper bush visited, a ‘post-it-note yellow’ lichen Vulpicida pinastri. As I looked further into the juniper bush a mass of orange coloured “tentacles” were seen covering the main stem of the bush, this was a strange fungus with a double life called Gymnosporangium clavariforme (both shown below left - don’t you just love these Latin names!) which appears first on its primary host juniper, from which spores are released in April. The spores travel on the wind until they meet their secondary host either hawthorn bushes or apple trees and there the fungus appears again in the autumn but in the form of yellowish depressions on their leaves. This outing resulted in my first tick bite of the year. Studying a section of geology map borrowed from Donald I noticed another small outcrop of limestone by a burn near Bridge of Brown. I visited the site a few days later and found that there was a major quarry of similar age to the Lecht one complete with on-site lime kiln. Inside the mouth of the kiln was another group of moschatel flowers, a first for this particular 10 km square. On my climb back to the road my delight at finding a rare lichen for these parts Sticta sylvatica growing on an ancient willow was somewhat reduced when I found (yet another) dead buzzard.

The third week of April will be remembered for its sunny days, lack of rain and daily night frosts which caused havoc in the Firwood garden. The flowers which had been tempted to push on during the hot days (20+ degrees C) were all laid low by temperatures as low as -4 degrees C. The sun worked wonders on the butterfly transect and in addition to green-veined whites and orange tips, one section on the moor produced 21 green hairstreaks (right), more than is normally recorded in a whole season. Netted mountain moth and cream spot ladybird were also found. On the 24 April Janet attended her first Cairngorms Farmers Market in Aviemore an interesting day and a new outlet for her crafts (see http://www.cairngorms-farmers-market.com/index.html and click on Craft Producers). An amazing day where a patch of grass was converted into a tented market in about an hour and all packed away in about half that time at the end of the day, all by the stall-holders themselves.

The most emotional day of the month had to be the 26th. The day started early with my early morning tramp over the hill to complete my first breeding bird survey of the year for the BTO (http://www.bto.org/volunteer-surveys/bbs ) and then it was into the car to drive over to daughter Laura’s for the local planners decision on an application to install two 80m high wind turbines within a 1000m of Laura and Douglas’s home. The nearest home was half that distance. A year ago I did an independent bird survey of the proposed turbine site to help with the resident’s objection to the application, though at the end of the day this sort of data seems to carry little weight with the planners. The meeting started at 2pm with applicant and objectors assembled for the decision. Short presentations were given by both sides before the Councillors had their say on whether they would support or object to the application. The tally list in my notebook showed most seemed to be against and eventually the chairman of proceedings brought the meeting to a close by saying planning consent would be refused. It took a few moments for what had just been said to sink in but when it did the Cairncake objectors/residents clapped their approval to the planners decision. Tears flowed, hugs all round and huge relief after two years of hard work by all those involved (right). Will there be an appeal? It would be hoped not but watch this space. The objectors exposed many flaws in the application, the planning process and the way the turbine company collate their data and to see what they found visit http://www.cawt.co.uk/index.php?page=cairncake .

The end of the month was sealed with THAT KISS though I was baby-sitting at the time.

That’s it for another month, enjoy the read.
