Greetings on this the shortest day

November started with the now annual visit to the National Trust for Scotland’s Haddo Christmas Fair where Janet’s tweed crafts were on display for the public to buy.  Despite the gales and rain for part of the weekend good numbers of folk turned up to see the various stalls and crafts and Janet was reasonably pleased with the number of bags, scarves and cards sold.  Once again daughter Laura and Douglas did us proud by providing accommodation and good food and Laura using her ex-Next manager skills when

helping out on the stall.  Both had also been working hard to apply the finishing touches to their new kitchen in time for the Haddo weekend and what a brilliant space for cooking and dining they have created, something to be truly proud of.  While Janet was selling I was again poking around in the estate woodlands, though the Saturday afternoon searches had to be done under an umbrella meaning it was just too wet to photograph the stinkhorn fungus (Phallus impudicus) and the bluing bracket fungus (Postia caesia) on a couple of dead conifers.  The latter fungus is cursed by the timber industry because, as the name implies, once present the timber under the bark is stained blue by growing fungus and though the wood isn’t weakened the blue colour implies the opposite and affects the saleability of the sawn timber.  Returning to Haddo on the Sunday morning the wind was up to gale force and it was interesting to note that only one of
Janet's Haddo Stall
the many wind turbines was turning, but no doubt the owner was still being paid vast sums of money.  Odd that we don’t get paid anything when the sun doesn’t shine on our solar panels!  Let’s not go there!  Wishing Laura and Janet well for the day I headed off to an old bit of mixed woodland I had spotted the day before just on the edge of the estate.  Monster elms mixed with beech, spruce and sycamores, though about half the elms were in the dying phase possibly as a result of Dutch elm disease.  The elms were searched for the presence of the lichen Gyalecta ulmi a once regular species found on shaded bases of old elms but now quite rare due to ravages of Dutch elm disease.  None was found but a fallen sycamore branch was covered

with a mass of the orange coloured fruiting bodies of the glistening inkcap (Copinellus micaceus) and the small, coral-pink cushion-like fruiting bodies of the coral spot (Nectria cinnabarina) a regular fungus of decaying branches.  In a dark crevice on one of the elms I noticed several pinhead lichens growing from a very green, granular thallus (the body of the lichen containing the fungus and algae) and not knowing which species it was a small sample of bark, with lichen, was removed for checking.  Once home, a day later, I had a look at the pinhead under the microscope and was amazed to find a couple of small flies wandering around on the lichen, occasionally hiding in wee cracks but not making any effort to fly away – interesting.  Whilst at
The barkfly Ectopsocus petersi
rest I was able to obtain a few photos which I emailed to expert Stephen for advice and was informed that they were a couple of barkflies belonging to the insect order Psocoptera, an outdoor version of something called booklice which occur indoors.  From the photos Stephen offered the name Ectopsocus petersi but couldn’t be 100% certain without actually seeing one of them.  Whilst checking the name and lifestyle of barkflies amazingly I came across the National Barkfly Recording Scheme and organiser Keith offered to look at one of the flies to confirm identification and also to add the specimen to the collection.  A few days later and the name was confirmed as Ectopsocus petersi highlighting the brilliance of local recorder Stephen.  The identity of the pinhead lichen is awaited but looks like one of the Chaenotheca species possibly trichialis.

Once back from Haddo Janet set up the Firwood Chalet as a mini-craft shop and for two weeks opened on a daily basis.  A percentage of all sales was donated to the local branch of the charity Macmillan Care.  The same day I attended a liaison meeting between Badenoch and Strathspey Conservation Group (BSCG) and a couple of the Cairngorm National Park staff regarding their Nature Action Plan and visited the newly
Nethy village walks
created paths in woodland in the village to help provide ideas for interpretation boards to be installed in a couple of places along the paths.  Ongoing visits were also made to the proposed An Camus Mor “new town” of up to 1500 houses adjacent to Aviemore to record species that might help with the legal challenge to try and stop the development, currently going through the courts.  A boost to funds for this appeal came from Lush Cosmetics, the ethical and campaigning cosmetics company who donated £7000 to try and protect the Cairngorms National Park from housing developers (see link below).  An ongoing concern about
Puccinia caricina fungus on leaves of common sedge
this development is the poor quality of some of the environmental surveys giving conservationists the impression that this development, which has the full backing of the SNP dominated Scottish Parliament, will go ahead whatever is found on site.  Under freedom of information requests details of these surveys has now been released to BSCG and on checking the bird data we find that the surveyor recorded reed warbler (unheard of this far north) and makes a case for habitat creation for kingfisher and grasshopper warbler in a

site currently dominated by woodland!  Sorry, I digress.  During my site visit I recorded big-billed crossbills (Scottish or parrott crossbill and absent from the survey) and the tall delicate pipe club fungus (Macrotyyphula fistulosa).  By a woodland pool I came across a fungus growing on common sedge (Carex nigra) leaves which looks to be Puccinia caricina var. paludosa, not recorded locally, but overall nothing too spectacular was found.  Visits will continue to see what else is on site, particularly in the bird line.  Whilst the local recorder was away on holiday I also visited a local hen harrier roost site to see how many birds flew in for the night, but nothing appeared despite watching the site until darkness made viewing i

mpossible and the moon starting to appear over the hills.  Quite a sad count really.  In the past up to seven birds have been recorded but dropping down to just one to three in recent years.  The roosting birds have almost always been “brown” birds either females or juveniles but whether breeders from the local area or visiting wintering birds we just don’t know.  If these are local birds, then the trend is quite worrying.

An email from Andy at Abernethy NNR mid-month required investigation.  An RSPB staff member had been driving along a road a couple of miles from the edge of the reserve and had noticed many trees in one section of woodland near to Nethybridge had brown tops and wondered whether one of the many diseases threatening our native trees was in the forest.  The other option offered by Andy was it might be something to

create the RSPB Abernethy NNR
do with beetles, so time to go and have a look.  When this section of woodland was bought by RSPB in 1994 (pink area on map) it had previously been managed as a commercially productive forest by a pension fund, with large blocks of the woodland comprising closely planted and even aged trees.  Whilst ideal for producing tall, straight trees of good saleable quality, the biodiversity value of the woodland was quite low; much of the woodland lacked any invertebrate rich ground vegetation, and, with tiny crowns, the trees were lacking branch development and hence cone production.  After some initial survey work a plan was put in

place to irregularly thin the woodland to create diversity in tree density and encourage plant growth.  Because of the size of the woodland this had to be done using modern, forestry machinery comprising timber harvesters and forwarders to fell and extract the timber, but the harvester was also used to create standing deadwood by lopping off the tops of some trees as it progressed through the woodland.  To monitor change I undertook monthly bird surveys of the main woodland area being managed using a fixed 100 metre grid to ensure that the birds were recorded at the same “points” on each visit – hence the term “point counts”.  Visits were made in the early morning and at each point (50 of them) birds were recorded for a period of

five minutes before moving on to the next one.  This survey continued for six years but analysis revealed that this is probably too short a time period in the life of a forest to see any major change.  It might take 10-15 years for the forest floor vegetation to respond significantly and dead trees created by the harvester would also take a similar time to provide suitable “soft” wood for birds to excavate nest sites, so recording might be repeated every 10 or so years.  During the development of the management planning process another major decision was taken, and a halt was called on any “extractive” management of the timber resource; all future thinning would be by deadwood creation, pulling over a few trees, ring-barking and high-topping to create standing deadwood.  Whilst being somewhat artificial, this management would address one of the major

problems with all our “native/natural” woodlands, a lack of deadwood.  And so, a couple of years ago, a timber harvester was used to re-visit the previously thinned areas and work its way through the trees creating deadwood (standing and lying) as it went.  The creation of so much freshly dead timber worked particularly well for one invertebrate – the large pine shoot beetle (also known as the pine bark beetle), and as I wandered through the section of woodland where the tops of the trees had been seen to be browning, I

could see that I probably wouldn’t need to check the pine needles I had been collecting under the microscope.  All through the managed area there were pine shoots (the very tips of the branches) lying on the ground and in the central, woody portion of most shoots there was a tiny hole. By carefully pulling the shoot apart I was able to find the answer to the problem – Tomicus piniperda – the large pine shoot beetle, though at 4mm in length, large it certainly wasn’t!  The creation of standing and lying deadwood had turned

the woodland into pine shoot beetle paradise and in the year the trees had been managed, beetles had landed on the fallen timber and immediately dug their way through the bark to lay their eggs between bark and tree sap-wood.  The new generation of beetles then emerged through new holes in the bark and then looked for a safe place to spend the winter months (in the pine shoots) before looking once again for breeding sites (new deadwood) in the spring.  During windy winter days the point where the beetle has entered the pine shoot becomes vulnerable to snapping and hence many end up on the ground where they continue to live quite happily until the next spring.  There is always a surge in the numbers of these beetles after any conifer thinning
The pouched false morel fungus

work so what has happened here isn’t unusual but perhaps the quantity of deadwood created should be re-assessed before more thinning work is carried out.  It looked like as many as a thousand beetles per log could have been emerging during both of the last two springs meaning tens of thousands of beetles on the lookout for homes for winter.  A bonus, as often happens on these outings was finding a couple of fruiting bodies of one of the late autumn/early winter pouched false morels (Gyromitra infula) a third record for Abernethy and with only 53 records on the UK fungal records database.

A first flurry of snow on 19 November had the garden birds demanding a bit more food so the first of the monster fat cakes were produced and put out.  A chance glance out of the utility room window a day earlier spotted one of those rare winter bird moments as I noticed a male blackcap feeding amongst some spilt birdseed in front of the chalet. It disappeared before Janet saw it.  I should have assembled the camera and
Look hard & there is a male blackcap on right of photo
telephoto right away because a few minutes later Janet shouted say it was back, this time in the cotoneaster hedge where it struggled to swallow a nice red seed, food the blackbirds had been making use of a few days earlier.  The blackcap then appeared on the trellis right outside the window and my annoyance at not having put the camera and lens together grew enormously.  It stopped long enough to devour a honeysuckle seed

before returning to the cotoneaster hedge where I just about managed to capture a photo with the standard lens camera.  And that was it, hopes of a wintering blackcap diminished as there were no more sightings by the end of the month.  With the telephoto lens now in place a few other birds posed for the camera, dunnocks in the flowerbox, blackbird in the cotoneaster hedge and chaffinch in the snow on the trellis. A

female bullfinch was snapped as it wandered around the rowan tree looking for any remaining berries.  As the snow eased and the thoughts of frost loomed I dug up the last of the tatties, red roosters and white maris pipers, quite a nice crop and something to think about planting again next year.  On my outing to the hen harrier roost I noticed in passing, an old quarry by one of the tracks and, knowing how good the occasional one has been for unusual species I thought a return visit would be worthwhile.  The relatively mild weather of November ensured that quite a few fungi continued to appear so I found it hard not to pop in and out of the

birches as I made my way to the quarry.  A few more fruiting bodies of the pipe club fungus were found and a rake around in the fallen leaves managed to turn up its close but diminutive relative the slender club (Macrotyphula juncea).  There was even a fly agaric still fully resplendent with red cap and white dots.  The old quarry produced a couple of Peltigera lichens and as I wandered back and forth a small bluish fungus caught my eye.  First appearances made me think of a waxcap, but so late and not in grassland?  The
Hygrocybe lacmus about 65mm high & cap 25mm diameter
camera was set up and a few in situ photos were taken and when I found there were about six fruiting bodies I took one home to check the spores.  Under the microscope the spores were easily found and the brilliant book The Genus Hygrocybe by David Boertmann, lead me to either Hygrocybe russocoriacea or H. lacmus settling eventually (with a little help from expert Liz) for H. lacmus (Schumach.) P.D. Orton & Watling, an amazing little waxcap with a bluish grey cap and spores in the range 7x6ยต.  Once again the name of Peter D. Orton appeared linking the man who did so much recording work at Abernethy was also the first to describe this particular fungus.  Brilliant.

November ended with the Highland Biological Recording Groups AGM with yours truly added to the committee.  Laura popped over for the day as Janet and myself looked after the two older grandchildren for a couple of nights allowing Ruth, Lewis and Harry a long weekend in Edinburgh.  We even did the school and playgroup run on the Monday getting home mid-afternoon to a welcome cup of tea followed by something a little stronger!

25 years ago, as I type, was a day we will never forget.  On the 21 December 1988 I said cheerio to my assistant warden Richard as he headed off south to be with family and friends over Christmas.  Just after 7pm the radio and TV channels were interrupted to inform us of the horrors just unleashed on the tiny village of Lockerbie and surrounding countryside.  Thankfully Richard had passed the village a few hours earlier and unlike those caught up in the terrorist atrocity was able to spend the festive season with his family. 

As I have been typing this, supposedly in winter and on the shortest day, a small black dot between my fingers has turned out to be A TICK!  Do these wee blighters not have a few months off each year?

Enjoy the read and best wishes for the festive period and 2014.
