Stewart meeting Stuart was almost un-reportable

The one bit of advice from this diary is ALWAYS BACK-UP YOUR COMPUTER FILES!  For weeks now I had been a bit lax in linking up the two big external hard-drives to copy over all the photos, word and excel files and on 5 September, as I was downloading yet another set of photographs from one of the camera cards a strange message appeared telling me the computer was unable to save a Word file I hadn’t used in ages.  More worrying was the sight on screen where some of the photos were shown as black boxes, so I stopped everything, and tried again.  More messages telling me that unsaved data might be lost etc, and when I tried to opened the files stored on the 1TB external hard drive, nothing appeared and visions of having lost all the holiday photos, all the natural history stuff including the late at night homework photos of galls, fungi spores – some possible photographed for the first time, filled me with horror.  Help!.  At a guess, I probably hadn’t backed up my files since about May and as I tend to keep a photo diary which is linked to
Photos of the fungal growths on twinflower were almost lost
my pocket diary as a help to what was photographed, I knew there was a lot at stake.  Half an hour later I was seeing computer expert Barry at Baztex in Aviemore to see if there was any hope that somewhere in the hard-drive “box” the files still survived and he provided some hope by saying “possibly”.  After selecting a new Samsung hard-drive off the self I left with everything crossed that Barry would find the files and copy them to the new hard-drive.  At 5pm I could wait no longer and phoned to see if the files had been found only to be informed that raw data had been in the process of transferring for five hours and that there was another two hours to go before we would know if the photos and other files were there.  After a terrible nights sleep there was great relief when the phone rang at half ten to say the files were all there and that in exchange for a heap of money, I was free to pick up the new hard-drive, and get on with life.  Back home, the next couple of hours were spent making copies of all the files, work that I should have been doing on a regular basis since May.  With Barry’s help, I now have a few photos available for this month’s diary and have written out one thousand times – ‘I must remember to back up my computer files!’  Barry had also a bit of input into the last diary.  Having struggled to get my photos in the right place in the diary (as you may have noticed) he suggested that I should use Google Chrome as a replacement for Internet Explorer.  Not being very computer savvy the though of upsetting the machine filled me with dread, but, as I tried to work unsuccessfully with the last diary I thought there was nothing to loose.  It worked, and a slightly new format of diary was created and the photos were dead easy to work with.  I hope you approve.

You may have noticed that a new pastime has been creeping into the diary – fungal smuts on sedges.  The first ones were found on flower-heads of spring sedge (Carex caryophyllea) when counting the orchids at Flowerfield Meadow in June, with new sedge/smut combinations appearing in the last diary.  Martyn, at Kew, emailed to say that there were very few records of these unusual fungal growths and that if possible, I
Mud sedge - Carex limosa
should try and keep an eye open for them whilst out and about.  A few species are listed in the “Ustilaginales of the British Isles” but Martyn suggested that there were many more out there “to be found”, knowing that I was likely to take up the challenge.  The list mentioned above said that the smut, Anthracoidea limosa was found on mud sedge (Carex limosa) and knowing of a few local Abernethy sites for the sedge, off I went in pursuit.  Mud sedge is one of the “bonnier” sedges with fans of green leaves spread across the bog from which arise the flower stems about six inches high and with nice pendulous flower heads, all looking quite delicate.  Despite a couple of hours of searching, bent over double to check the flower spikes, nothing was
Fungal smuts on the Deergrass Trichophorum x foersteri
found so a few days later I visited another location with fewer spikes of mud sedge but with lots of other sedges with potential for the smut fungus.  However, it wasn’t a sedge that produced the first smuts but a common plant of damp moorland called deergrass (Trichophorum species).  For many years botanists wandered the moors listing the plant as deergrass (Trichophorum caespitosum) until someone took a closer look and eventually identified two distinct species (T. caespitosum and T. germanicum) and, where both species grow together, the hybrid Trichophorum x foersteri.  The fungal balls looked so unusual on this
Bog orchid
plant that I began to wonder if anyone had previously recorded Trichophorum as a host species so very carefully a few specimens were collected to check under the microscope and photographs taken to show the smuts on the flowerhead.  The deergrass turned out to be the hybrid, which is sterile so not sure what the fungus was growing on, but the specimen was dried so that the experts at Kew could delve a little further.  More smuts were found on star and carnation sedges but find of the day came right at the end when, peering down at the bog plants something pale green and small came into view and the more I focused I realised that I was looking at a flower, no more than an inch or two high, which had to be bog orchid (Hammarbya paludosa), a flower I had only seen in two locations previously.  The more I stared the more plants I could
Many bog orchids on tussock
see, and one cottongrass tussock had about 15 flowers growing from it.  There were more in the mud of the tiny runnel, and more in the other bits of vegetation close by.  In all, 60 flower spikes were counted, and in the mud there were several non-flowering “bulbils”, perhaps young plants that would flower the following year.  It turned out later that this was one of the biggest populations recorded in recent times, so once again, searching for one species turned up another!

When leaving our holiday accommodation last year Kate informed us that she already had lots of bookings for summer 2013, and so we opted for a later August visit this year.  The dates chosen would allow Janet to attend the local Abernethy Highland Games with her craftwork before heading off once again for South Uist.  The Games this year were to benefit hugely from various village projects aimed at providing better village

walks but also opening up the dense spruce plantation all around the eastern boundary and creating better car parking and visitor access following the purchase of the field adjacent to the Games field/football pitch.  As previously we went down to the Games field on the Friday to set up the tent but this year had grandsons Finlay and Archie in tow.  With the running track all marked out on the football pitch I took them both for a wee jog up and down the 100 metres track but then they both took off and we ended up jogging round the bigger circular track.  Archie and myself did a couple of laps in a stop-start sort of way but Finlay was off and we had a job to stop him, even after three laps, as it was time to head back to the house!  An early start on the Saturday saw the tables and tweed crafts installed in the tent, a job made easier by the arrival of
Scott Rider
daughter Laura who had driven over to help.  By half-ten, the children’s events were getting underway and highland dancing competitions had started so time to leave Janet and Laura on the stall and nip up the road to walk the weekly butterfly transect, week 19 of 26!  Returning to help pack everything away was perfectly timed as one of the heavy events – 56lb weight over the bar was just reaching its climax and with just three competitors still in the event (the others having failed to get the weight high enough) the announcer was building up the excitement by informing everyone that the bar was getting close to a Games record.  As the
Success
record height was reached there was just one competitor left, Scott Rider, and there was a very loud Ohh from the crowd as the first attempt failed to creep over the bar.  The Ohh though changed to a huge cheer as the second effort sailed over the bar and once everything had been re-measured a new height went into the record book.  An hour later, everything was packed away at the end of another successful “Tweedcraft” day.  Thank you Laura.

One of the last outings before heading off on holiday was a second visit to an area of limestone quarrying last visited in March 2012.  On that visit I had very limited information about what was where and having found a good area where limestone had been removed, I spent the day there.  But early in August botanist Andy and geologist Donald both told me about two big lime kilns that they had recently seen, and Andy had inspired

me to re-visit by one of the plants he had found growing there.  The plant, alpine enchanter’s nightshade (Circaea alpina), had been on my list of “things to try and re-find” following my 2012 visit, but hadn’t materialised.  The extensively quarried area is now within a tree regeneration fence, and, as the fence has proved to be more and more successful, less of the site is easy to visit because of the dense growth of trees, juniper and, in places, bracken.  The kilns alone looked worthy of a visit from the photos I had seen so off I went.  A different track to the site from my first visit took me right to the fence where one of the kilns was clearly visible, and whilst not as impressive from the photos as the other kiln, it looked much more unusual
Nettle-tap moth - Anthophila fabriciana
owing to its low build.  The fencers had been very kind and there was a gate in the deer fence giving access to the site.  The first stone slabs of the kiln also showed that the site could be good for lichens as, without really looking, I could see a decent population of the lime loving lichen Solorina saccata.  The more gaps in the stonework I examined, more of the lichen was found and I was hopeful of more finds.  The same lichen had been found during my 2012 visit so wasn’t new to the site.  However, despite lots of searching, no more “unusual” lichens were found, this though, was more than made up for on the botanical side.  With the lichen were lots of the wee fern maidenhair spleenwort and a small moth which stayed still long enough to be photographed turned out to be Anthophila fabriciana, the nettle-tap moth – more good names!  Instead of small, deep rock quarries, most of the site was covered with spoil-heaps, the residue of what couldn’t be burnt to produce quick-lime.  In amongst a good population of maindenhair spleenwort something a little
Green spleenwort top and maidenhair spleenwort below
greener caught my eye, my second local site for green spleenwort, a much rarer relative of the former, with few sites locally.  Growing side by side it was quite nice to be able to check the differences between these two similar looking ferns.  Maidenhair has a black stem throughout and sori (spore masses) in lines on the underside of the leaves.  Green spleenwort has a green stem (but dark at the base) and the sori are much more obvious under the leaves.  Subtle, but different.  A few clumps of the rarer fern were seen and on returning home a quick check of books and NBN informed me that two good local botanists had both recorded the plant – but 46 years ago.  Brilliant.  Now the difficult bit.  I had a rough map of where the alpine enchanter’s nightshade had been found, right in the middle of a dense patch of mature and spiky
Alpine enchanter's nightshade - Circaea alpina
juniper.  No doubt, when first found in 1973, the hillside would have been grazed by sheep and deer and the juniper would have been more open.  But now, with grazing excluded, the vegetation generally was much more luxuriant, though I could see evidence (wool) that the odd sheep did manage to find a way through the fence.  Without the juniper, perhaps the plant wouldn’t have survived.  Waterproof pants on (to stop the juniper needles filling up my wellies) I started to visit the juniper bushes, looking into each as best I could.  A few bushes were so big and old it was actually possible to crawl into them, and by using this technique I was eventually successful in finding the plant, not a lot of it in the bush I had crawled into, but it was readily identifiable as the plant I was looking for.  A few spots on some of its leaves caught my eye, so one was
The massive lime kiln
carefully removed to take home for checking.   Before exiting the enclosure I followed the fence for a few hundred metres to have a look at the second, huge kiln, possibly one of the biggest I have ever seen.  A search of the brickwork and adjacent soils failed to find anything of importance so just time to hop over the fence to try and get a photo of the kiln – not easy to show all of it due to fence, slope etc, before heading back down the hill to the car.  The spots on the alpine enchanter’s nightshade leaf revealed a spotty orange fungus on the underside and when looked at under the microscope the spore size and plant host lead me to Pucciniastrum circaeae a fungus with few records in Highland Region.



                                  Holiday quiz -can you see a butterfly?

And so, mid-month, we headed off to South Uist, the latest we had ever holidayed in the Uists.  The ferry from Uig on Skye was not until 5pm so we had a leisurely drive west and even had time en-route to make another visit to the thyme broomrape site.  Far too late to see the plant in all its glory, but at least we would be able to make a count of the number of flowering spikes.  A total of 17 were seen, four times as many as
Compass jellyfish - Chrysaora hysoscella
we saw in 2012.  I had been watching the weather developing during the week and sure enough, we had quite a breezy crossing, and possibly the same winds that had roughed up the open seas along the west coast enough to detach lots of seaweed which we saw everywhere washed up in heaps along the beaches.  This was probably most obvious on our first beach outing where the seaweed was almost wellie deep in the corner of the beach.  As we walked we also noticed lots of jellyfish being washed in close to the edge of the sea, lots of compass jellyfish (Chrysaora hysoscella) and many that I think were moon jellyfish (Aurelia aurita).  In amongst the bits of seaweed I spotted something that I thought was a roundish piece of blue

plastic about three inches across and with a section sticking up at ninety degrees - a convenient wee handle by which to pick up the “flotsam”.  As I did so I had the feeling that I was looking at a type of jellyfish, with the wee handle actually looking like a sail.  “Sail by the wind jellyfish” came into my head which, when we got back to the cottage, wasn’t far from being correct.  It was Velella velella or “By-the-wind-sailor”, not a true jellyfish but colonies of tiny animals called hydroids all coming together to create this amazing creature which floats around on the surface of our seas.  See the link below for more details.  This is possibly a new species for South Uist the nearest previous record being on Barra.  Another day and another surprise on another beach.  Half a dozen ravens, way in the distance, had caught my attention, and as we were heading
Striped dolphin about 2 metres in length
in their direction I had the feeling that we were going to find something dead.  As we got closer I could see what looked like a dead seal but as we got to the animal it turned out to be a small, possibly common dolphin.  It had been dead for a little while but was still in a good enough condition to make a wee sketch and take a few photos to send to the sea mammal strandings folk.  Initially they were happy that it was a common dolphin but when we got home another email arrived to say that from the photos it had been identified as a striped dolphin Stenella coeruleoalba.  Obviously the meadow pipit and tree pipit of the dolphin world.  Being later in the season it took us three days to see our first short-eared owl but eventually we had a fly-by at the cottage.  The following day we had both s-e owl and hen harrier near to the cottage, the latter species having proved to be quite elusive when trying to photograph.  On a brilliantly sunny day we visited Eriskay and having parked the car near the ferry terminal we had walk along the road to Parks.  The road petered out into a track which lead nicely down to the rock shore complete with ruined croft house.  A rock outcrop looked interesting and provided a new site for sea spleenwort and just everywhere there were dark-green fritillaries charging about in the sunshine.  On the way back I left Janet to go and check out a group of aspens growing on a rock outcrop (away from the many sheep) and one minute I was making
The famous rock where the SS Politician floundered in 1941
steady progress forward and the next I was flat on my back in what might have once been a ditch but now much overgrown with brambles!  Everywhere I tried to get a hold to pull myself up there were brambles and with my rucksack still on my back, it was almost impossible to roll over.  Eventually I was able to use my hat to protect one hand whilst I slowly managed to extricate myself with a nicely lacerated arm and with many embedded bramble thorns which took a few days to find and remove.  Ouch!  Worst of all there was nothing of note on the aspens!  We ended our outing with a nice bar meal in the Am Politician pub (yes commemorating the famous SS Politician which floundered close by in 1941) and behind the bar there is even a bottle of the famous whisky on display.

Perhaps the most memorable outing on this visit was to a bit of woodland (yes, a rare piece of established woodland) that has remained undetected by the pair of us over all our visits.  A dram with ex-Rum resident John Love at the cottage one evening lead us in the direction of sea eagles and woodland during our
Loch Aineort woodland
conversation and John suggesting that both might be seen in the Loch Aineort area just down the road.  John was the man responsible for looking after the many sea eagles brought over to Rum, between 1975 and 1985, right at the start of the re-introduction programme with me helping out when John was off the island.  This piece of woodland, not shown on the current OS maps covers several hectares and has been established by the determined efforts of one man, Archie Macdonald, who lives on site and is constantly adding trees to his small estate.  At the trees are maturing so the regular fungi and galls are already starting to establish themselves.  Not only is Archie planting trees but he has created paths everywhere so that visitors

can enjoy visits to the woodland.  After our walk through the woodland we headed further round the coast to an area of genuine, natural woodland, a small area of broadleaved trees in a steep sided gully.  SNH have recognised the importance of this ancient, surviving remnant of natural woodland, have provided help to fence the area off so that the trees that have survived to date, have a chance to expand by natural regeneration.  Aspen, birch and willow are all present so hopefully the start of a woodland for the future on these largely treeless islands.  No eagles, but a very special part of South Uist and, with a seal on almost

every rock jutting out from the sea well worth the visit.  An outing to the Daliburgh area saw us heading out to high-tide island of Orasaigh and as the sun came and went so did the last of the seasons grayling butterflies and as I munched my lunch I wandered back and forth firstly trying to see one of the butterflies and then trying to photograph one.  Unlike last year when the graylings seemed to detect the focusing mechanism of the camera, this years butterflies were a little more accommodating and at least did let me get close allowing me to add an additional photo to the one posted above.  Now can you see it?  The corn buntings continue to

disappear at an ever increasing rate and despite being out and about most days we only heard 2-3 on the RSPB Balranald Reserve.  As the buntings decrease so the changes in agricultural practices continue apace with silage rather than hay being the main winter feed being produced for the farm stock.  Does it have a part to play who knows, but it won’t be long before one of the Uists most iconic birds will be lost for ever.

And all too quickly our holiday was over and we packed up and headed for home.  Whilst on the islands we had seen that one of the past Osprey Centre staff was now working on the Balranald Reserve and the wider area monitoring some of the key species.  We didn’t meet whilst visiting the reserve and we didn’t have time
Stuart meets Stewart
to pop into an RSPB open day event as we headed back for the ferry to see if he was there.  An email to say sorry we missed you would have to be sent once we got home.  There were quite a few small dolphins close to the ferry as we headed out from Lochmaddy and a few folk were on deck trying to see them.  In the distance was a face I thought I recognised so I dashed over to ask “Stuart Taylor?”  Sure enough this was the man that we had missed on the islands and here he was heading for the mainland on the same ferry.  Amazing.

Enjoy the read.
