Still stumped – but numbers increase

Goodness, where did May, and for that matter, June go?  The 1st May saw Janet and her craft tent at the Nethybridge Spring Gathering, another successful day for all those organising and attending.  In 
between helping put up and take down the tent, I sneaked off to return to stumps where the stump lichen (Cladonia botrytes) had been found in the previous week to carry out stump size measurements.  More about this bonny wee lichen a little later.  The next day it was off to the damaged Spey Bridge aspen wood near Grantown on Spey to try and help Gus from the Badenoch and Strathspey Conservation Group with photographing areas showing some of the most damage to fallen aspens, felled hazels and general lopping off chunks of trees because they looked ‘untidy’!  At the site where the ancient aspen supporting a big population of aspen hoverflies in 2015 it was very difficult to show the damage done because the tidying up had been so efficient.  However, I noticed a 
Glisrochilus quadripunctatus beetle
small red and black beetle in the depression created by where the trunk of the fallen aspen had lain and when expert Stephen saw the photo back came the name Glisrochilus quadripunctatus, a beetle with just a few old records in our area.  We continued to be amazed by the lengths the contractors had gone to where they hacked off bits of live trees and in a few locations we noticed that what had been

cut off was the aspen bracket fungus Phellinus tremulae, a fungus new to the UK as recently as 2000, and with a current distribution mostly in the aspens stands along our section of the River Spey.  However, it is not rare!  At a couple of these locations the cut section through the fungus showed clearly its link to the living section of the aspen tree.   A more remarkable record the same day was that Leicester City had been crowned Premiership Champions on a budget a fraction of the teams below them in the league!  A breath of fresh air!  A morning was also spent sorting out maps for this summer’s BSBI/CNPA plant survey, targeting again under-recorded 2x2 km squares (tetrads) in the Cairngorms National Park, a commitment to five of which will keep me occupied for the rest of the summer.

On the 5th, daughter Laura popped over for a few days with the Saturday evening outing being the start of a run up to a big family event – daughter Ruth’s hen party ahead of her June wedding.  Through May a rather ‘posh’ wedding dress had been residing in one of our bedrooms and had

accompanied Ruth on a few of her college days in Elgin for up to the day fittings.  Janet has been busy on her sewing machine preparing napkins, tablecloths and table decorations for the wedding meal and Lewis’s (husband to be) mum and partner have been extremely busy re-designing their house garden for the fingers crossed, open-air wedding booked for the 18 June.  Just to complicate things a little Janet and myself would disappear off for a holiday at the end of May, booked ahead of the wedding date, only getting back home nine days before the big event.  Watch this space…

Early in the month the first BTO evening woodcock survey was completed, a survey which is developing into an annual event because of the serious decline in UK woodcock numbers identified by other BTO breeding and atlas surveys.  This first outing saw me making my way back to the forest plantation near the River Dulnain in time for the count to start at 9.15pm.  As I crossed over the 
Primrose display
Sluggan Bridge I could see in the distance an amazing sight of a yellow hillside created by a huge population of primroses, a place I had promised myself to visit when I saw it the previous year.  However, I didn’t make it then but, having seen it again I planned a return visit, in the daytime.  Nothing had changed along my route from bridge to count location but as I emerged from the dense stand of Norway spruces and birches onto the forestry track I noticed something moving a little way ahead of me – a mountain hare – in the forest!  As it stopped on the track to look back at me a second one appeared and both sat for a minute or so, watching me, just enough time to get their photograph.  The count period of 75 minutes produced just 3 roding woodcock contacts so to keep me alert I made

notes of the last bird singing as darkness started to fall.  Once again it was a robin, out-singing the song thrush by about 15 minutes, and last heard at 9.57pm.  The last fly-past by a woodcock was at 10.35pm.  The second of three counts took place about a week later and this one – 9.30 to 10.50pm – didn’t produce any woodcock at all.  The last singing bird though was a much closer call with the last song thrush at 10pm and the last robin five minutes later.  Overhead, as the clouds parted, the half-sized moon shone clearly in the sky with the planet Jupiter almost by its side.  The third visit would have to await our return from holiday and the wedding.

A couple of days after the first woodcock count I was back at the primrose hillside to admire the sheer number of plants, a rarish sight in this area, and to keep an eye open for a rare weevil that might occur.  At my first find, a group of heath dog violets (Viola canina) I realised that I had left my GPS behind so was unable to make a note of the exact location, but finding more of the violet, I didn’t need the 10-figure grid reference.  The blaeberry/mountain bumble bee (Bombus monticola) was 
Brown silver-line moth (Petrophora chlorosata)

feeding on the primroses and a green-veined white butterfly was enjoying the sun and 230C of heat.  A moth at rest had me a bit puzzled but a photo let me see that it was a brown silver-line (Petrophora chlorosata) once home.  Similarly, a shieldbug resting on a juniper branch was also happy to have its photo taken and by visiting the gallery on the British Bugs website I identified the parent bug (Elasmucha grisea) one of the scarcer bugs in this area.  An old sap-run on an ancient birch had both of the scarce pinhead lichens Sclerophora pallida and peronella and in the wetter flushed ground tussock sedge (Carex paniculata) and fen bedstraw (Galium uliginosum) were both found.  Too many good records so this involved a return visit the next day to attach grid references to all the finds but

with even more heat with the thermometer reaching 260C!  At about this time a message had arrived from Murdo via the Highland Biological Recording Group to keep an eye open for the rare cranefly Prionocera pubescens, the one found a couple of summers ago whilst walking the Loch Garten butterfly transect.  In the back of my mind was an amazing bit of bog woodland brought to light by the January chalet planning application close to the Flowerfield orchid site so thought this might be a 
Prionocera pubescens cranefly
good place to start.  A similar looking beastie Tipula subnodicornis was the first cranefly to be caught in my net but the one I was looking for had ‘saw-like’ antennae, something the Tipula didn’t have.  Persistence paid off and about half an hour later and after the capture and release of probably a dozen more Tipula’s the one in my tube had the antennae I was hoping for.  ID was later confirmed by Murdo.  Hopefully, more visits to this wooded bog will produce other good records particularly in the butterfly group.

Once again, looking for one species produces another.  An email from fungus expert Liz alerted me to the possibility of a rare aphid, Cinara smolandiae being associated with the common juniper rust fungus (Gymnosporangium clavariiforme).  The aphid had been found recently at Dundreggan in Glen Moriston near Loch Ness on juniper stems where the fungus had fruited earlier in the year and there was a chance it could be in local woodland like Abernethy.  In early May the fungus was still visible on juniper bushes so I thought it worth a quick peek.  One way of finding aphids is to look for wood ants wandering up and down juniper stems to feed on sugary honeydew left behind by aphids 
Aphids (to be identified) on juniper
and, sure enough, by following the ants I found some aphids, some quite close to the fruiting fungus.  However, there is also a commoner aphid on juniper stems (Cinara juniper) so the ones I found have gone off to the expert to be identified, though nothing has been heard back as yet.  As I wandered homewards along the Speyside Way I continued to check the juniper bushes but also wandered into an area where lodgepole pines had been felled about 15 years ago, lots of stumps so I just had to have a look if there might be a tiny Cladonia botrytes lichen present.  Because of their age, the majority of these stumps were in an advanced state of decay with many starting to disintegrate, so I didn’t hold 
Stump lichen (Cladonia botrytes)
out much hope.  How wrong I was.  A tiny remaining bit of a heavily decayed stump, produced the first stump lichen, and further along the old plough-line another one turned up.  Help, this could be quite an important site, so I called a halt and planned to return another day equipped with my hand tally counter, measuring tape, red and white marker tape and better quality camera to see what might be present.  So, the next day I returned and walking the old plough-lines visited 370 stumps and managed to find 9 stump lichens.  A couple of days later I was back again and the 221 stumps checked revealed another 5 lichen sites and the next day 309 stumps added 1 more.  A start was then made replacing the roadside fence at the house, raising its height to try and stop roe deer jumping over to eat Janet’s flowers and my veg., so the day before we headed south on our holiday (25th) I made one last visit and the 172 stumps added another 6 sites which, if my maths are correct gives a total of 23 stump lichens in this one area of clearfell.  The biggest population at one site previously was at the Kindrogan Field Studies Centre near Pitlochry where 19 stumps held populations of the

lichen.  Add to this the 7 sites found in April Abernethy is, once again, proving to be quite an important site for rare species.  At each site a GPS grid reference was noted as well as the stump and GPS photographed in location.  A pencil was used to show roughly were the lichen was on the stump and photographed firstly from a distance and then close up before a good quality photo was taken of the lichen in situ.  Finally, the diameter of the stump was measured along with the height of the lichen on the stump from the ground.  Previous studies on Deeside and within Strathspey showed that stumps where the lichen had been found previously were between 15 and 90 cm in diameter (mean = 58 cm) and that the height from the ground was between 10 and 80 cm (mean 36 cm).  I have yet to analyse all my data but with the search still ongoing this will be something for the future.  Also, all the previous finds were on Scots pine stumps whereas mine so far have been all from lodgepole pine

with one from a Norway spruce.  Other features that are also developing show that the stump lichen isn’t always growing on the flat surface of the stump, some have been on the side, a couple towards the base of the stump as though the section of the stump supporting the lichen has detached and taken the lichen with it.  A couple of sites have also been sections of branch or log and at several sites the lichen has been growing deep in other lichens, in competition with other Cladonia lichens and on stumps where vegetation is also present.  An interesting research paper is starting to develop, re-writing quite a bit about the sites the lichen was previously known to occupy.  Interestingly, there is  quite a large area of stump habitat, created at the time of the EU Wet Woods Project still to check!

On the 26th we headed south initially to stay with Janet’s mum for a few days before heading ‘over the border’ to Masham in Yorkshire for the bulk of our holiday.  Whilst with her mum we managed a brief outing to the Salthills Quarry Local Nature Reserve near Clitheroe managed by the Lancashire Wildlife Trust.  Here we found that the round-leaved wintergreen (Pyrola rotundifolia) was still present (found September 2015) and a new species for both of us was spindle tree (Euonymus europaea), a single tree along the way-marked walk.  Whilst driving south on the M6 to Lancashire, just after Carlisle, there were lots of signs saying ‘slow moving caravans on A66’, little did we know 
Spindle tree (Euonymus europaea)
we would see the reason for this the evening we arrived in Masham.  En route to Masham we stopped off in Grassington to stretch our legs and once again visited Grass Wood on the outskirts of the village.  The leisurely walk turned up a couple of speckled wood butterflies but star of the walk was a group of four herb Paris plants, right by the track, just missed by one of the winter bonfires where brash from exotic conifer removal had been burnt.  On the road walking back towards the car we 
Herb Paris (Paris quadrifolia)
found a nice population of lily of the valley, a perfect introduction to the riches of this part of the world.  In Masham the owners of the property were on site to welcome us and once settled in we had a quick bite to eat before heading out to see the travelling folk with their horses and caravans parked up just across the road.  The rapid clip,clop, clip clop of metal horse-shoes on tarmac had us staring in wonder as a young lad with friend seated next to him came galloping along the road, horse, a simple buggy attached and the two lads smiling their heads off.  The effort taken to slow the horse 
down was interesting to see but along the road, around the field where a dozen or so families were parked up for the night, the young lad seemed to be quite an expert in controlling his horse and buggy.  There were several of the highly decorated ‘Romany’ type horse-drawn caravans, open two-seater carts, lots of horses many with foals at foot and vans, wagons and towing caravans all on their way to the annual Appleby horse fair, the event the signs on the M6 were warning us about.  Over the next couple of days the field emptied as the travellers headed north-west to Appleby.  Monday saw us leave the car at the house and walk up the road, along the River Ure to the Marfield Wetlands Nature 
Masses of flowers on the hawthorn bushes
Reserve.  The amount of blossom on the hawthorn bushes was incredible with most trees looking like they couldn’t possibly support any more flowers.  Cowslips galore and the cranesbill plants started to test our ID abilities with some requiring time with the flower books once back at the house.  Meadow cranesbill were everywhere but small-flowered and cut-leaved cranesbill plant were much rarer and only found on the nature reserve.  We also were re-acquainted with the red-and-black froghopper (Ceropis vulnerata) one of the largest members of the froghopper family.  The outing the next day was to prove quite beneficial for later in the holiday.  We parked up near Jervaulx Abbey and walked along a different section of the River Ure heading towards an area we visited last year.  However, the first mile or so was very poor plant-wise and it was only when we reached a gate which was the boundary between heavily managed farmland and SSSI farmland that everything changed.  Through 
Froghopper (Ceropis vulnerata)
the gate we were into masses of cowslips and primroses, crosswort and red campion.  Field garlic (Allium oleraceum) was just coming into flower unlike the ramsons which were in flower everywhere and some well past their best.  Something on the stem of cocksfoot grass looked familiar but was the wrong colour, one of the choke (Epichloe) fungi, but which one?  It would be later in the holiday before this query was resolved.  As we turned to walk back to the car a couple with their dog stopped to ask what I was photographing (field garlic).  For some reason we got onto talking about the meadow cranesbill and the lady said we should visit a site near to Leyburn to see the wood cranesbill which should be in flower.  In checking out were this was and what other flowers might be nearby a few interesting orchid locations emerged, something that will be covered in the next blog.
