Oisgill and Elsewhere

April 1, 2018

On Friday Seth, Tony and I went to Oisgill so that I could show them Ribes spicatum (Downy Currant) and Saxifraga oppositifolia (Purple Saxifrage). They had to take my word that the Ribes is this species as it has yet to sprout any leaves let alone flowers, but there is a good population of over 60 plants there.

The saxifrage, however, was flowering well as expected at this time of year.

We added eight taxa to the tetrad plant list, though two of these were the result of subspecies recording, captured some ants and spotted other invertebrates before moving on Abhainn an Lòin Mhòir near Dunvegan.  Here we added 12 to the tetrad plant list – the result of my not having recorded along the river gorge before – and did well for stoneflies, river limpets and native flatworms. Seth tells me that a large stonefly that had to be collected from my face was Perlodes mortoni, a recently split endemic (previously lumped with the Continental P. microcephalus).

After that, as a special treat,  I took them to my favourite quarry, east of Dunvegan where material from Dunvegan Castle gardens has been dumped years ago, plus an exciting collection of rusting white goods. Here apart from the unusual plants I have reported before, we spotted a New Zealand Flatworm (Arthurdendyus triangulatus), Field Vole (Microtus agrestis), Palmate Newt (Lissotriton helveticus), Water Cricket (Velia caprai) and Garden Snails (Cornu aspersum)

Caol Rona

September 3, 2017

We walked to the north end of Raasay on Friday – about 4 miles from Arnish.  The weather was good – that was why we chose Friday – and we had encounters with Red Deer, Common Dolphins and a flypast by a fine Golden Eagle.

Some plant recording refreshed records from NG65; ideally more should be done before the Atlas 2020 cut-off in two years’ time.

Curiously, there were quite a lot of Chevron moths flying, though these are not noted daytime fliers.  Also a fine Knot Grass caterpillar:

Isay

July 5, 2017

Today I went with the SWT Skye Region Group to Isay in Loch Bay. We last went there in 2008 – and before that visit there was only one vascular plant record and no bryophyte records. Isay falls into two tetrads NG25D and NG25I. Today I added 26 taxa to the vascular plant list for NG25I bringing the total to 102 and 27 to the list for NG25D bring the total to 193.

Nick was reasonably happy with NG25D but fears NG25I may be the dullest tetrad on Skye bryologically. We may have to go to nearby Mingay and Clett to help. Actually there are the remains of a lime kiln on the east side of Mingay which might augur well for bryophytes and vascular plants. Perhaps a Skye Botany Group excursion next year?

Several quite large areas of Matricaria discoidea (Pineappleweed) were found. These were not there in 2008. They mostly also contained Cerastium glomeratum (Sticky Mouse-ear) and Gnaphalium uliginosum (Marsh Cudweed). On Skye, these are all typically found in field entrances, waste ground, etc.  It seems likely that Greylag Geese are the cause of these new habitats, probably by a combination of bringing in the seed, fertilisation and grazing. These three species were all new to Isay.

Carex distans (Distant Sedge) was a first record for NG25, as was Castanea sativa (Sweet Chestnut) – I spotted 4 rather stunted, planted specimens which I obviously missed in 2008.

My last Hyacinthoides of the year?

Sagina subuata & Plantago coronopus LR

Otherwise, I saw my first Meadow Brown butterfly of the year plus Common Blues and Green-veined Whites. And a pair of Great Skuas defending territory. And Grey Seals. And Eider……….

A Week on Muck

June 18, 2017

I have just spent a rather wet and windy week on Muck with the Inverness Botany Group. I decided to record on a monad (1 km square) basis as there are only 13 and none has 100% land. However, it spreads over four 10km squares, three of which have no other land in VC 104. We made over 1,800 records and as well as re-finding old records of many species, we added Carex extensa (Long-bracted Sedge), Carex limosa (Bog-sedge), Carlina vulgaris (Carline Thistle) and Valeriana officinalis (Common Valerian) to the Muck list.

Fumaria bastardii (Tall Ramping-fumitory), distinguished by its large flowers but small stipules, was a good find with only two previous sites (on Muck and Eigg) in VC104 and no record since 1999.

Some Myriophyllum in  brackish pools led me to hope for M. spicatum for which there are no accepted records for VC 104, as this is the habitat in which it is found on Coll and Tiree and the Outer Isles.

However, the inflorescence being <3cm and the tip drooping in bud plus the basal whorl of flowers being in leaf-like pinnatisect bracts then others in pectinate bracts, tells me that it is the locally frequent M. alterniflorum.

We also recorded a number of insects, mammals…..

The Belted Beauty has yet to be recorded on Skye.

Also fungi, some of which are awaiting identification….

Later: Bruce tells me the fungus on Silene flos-cuculi is Septoria lychnidis, or as NBN has it Caryophylloseptoria lychnidis, and that it is found on other members of the genus too.

Berraraig Bay and Beyond

May 26, 2017

Back in the last century Dryas octopetala (Mountain Avens) (1976) and Epipactis atrorubens (Dark-red Helleborine) (1996) were discovered on the cliffs of Berraraig Bay. Then in 2006 I added a third Nationally Scare species to the same habitat, Cephalanthera longifolia (Narrow-leaved Helleborine).

For several years I have been meaning to get there in May when the Cephalanthera is in flower and on Thursday I achieved it. I counted over 40 plants, over a 700m stretch. I will certainly have missed some non-flowering specimens as quite a few plants are a little way up a near-vertical cliff.

This was an exceptional day for me in that I added the three Nationally Scarce species above to tetrad NG55C (as well as other nice things like Neottia ovata (Common Twayblade), and two to NG55H, Dryas and Equisetum x font-queri (Font-Quer’s Horsetail) as well as Neottia ovata again, and Vicia sylvatica (Wood Vetch).

Now I know Equisetum x font-queri, unlike Equisetum telmateia (Great Horsetail), is supposed to bear a cone at the top of fertile stems but this is ridiculous:

There were rusts and similar I haven’t found before:

and all sorts of other things – generally a great day.

Orbost & Healabhal Bheag (MacLeod’s Table South)

July 31, 2015

I had an excellent walk from Orbost Farm, up the Orbost Burn and on to Healabhal Bheag yesterday. Tetrads NG24G & L had their recorded taxon count raised from 12 and 6 to 107 and 173 respectively and a very brief wander into NG24F improved the count there from 12 to 65.

Ten species were found that had not been recorded in the 10km square NG24 since before 2000:

Botrychium lunaria Moonwort
Capsella bursa-pastoris Shepherd’s-purse
Diphasiastrum alpinum Alpine Clubmoss
Epilobium hirsutum Great Willowherb
Gentianella campestris Field Gentian
Neottia cordata Lesser Twayblade
Pilosella aurantiaca Fox-and-cubs
Salix pentandra Bay Willow
Saxifraga oppositifolia Purple Saxifrage
Vaccinium vitis-idaea Cowberry

and seven of these had never been localised to a tetrad before.

The preceding post shows Epilobium brunnescens (New Zealand Willowherb) on the south end of Healabhal Bheag, great swathes of it as one finds on the Trotternish Ridge.

Dwarfed Prunellla vulgaris (Selfheal) can look quite exotic once it loses its petals:

I had a close encounter with a fox in very fine condition and found this True Lover’s Knot

which as well as the Sparganium angustifolium (Floating Bur-reed) had Large Red Damselfly and another moth that declined to stay still long enough to have its picture taken.

There were Magpie Moths everywhere. Brian says from Carr Brae “we never see [them] here on the mainland any more.  Very strange as it used to be very common.”

I may have found Vaccinium x intermedium (V. myrtillus x vitis-idaea) growing with both parents (Bilberry & Cowberry) but I am seeking expert opinion.

Rubh’ an Dùnain – Skye Botany Group

June 16, 2015

Yesterday the Skye Botany Group visited Rubh’ an Dùnain.  Loch na h-Airde is Skye’s only brackish loch. In fact, judging by its taste yesterday it is highly saline, and it has seaweeds growing in it. It is the only site in the vice-county for Ruppia cirrhosa (Spiral Tasselweed). There was a great deal of tasselweed in the loch but there was no sign of flowers or fruit yet making separation from Ruppia maritima (Beaked Tasselweed) difficult. I have brought a bit home to see if it will develop flowers but on the basis of the dark green obtuse leaves and the previous records, I am content that that is what we were seeing.

We recorded in three tetrads (and made a few records in a fourth we walked through) and made a significant improvement to the numbers of plants recorded in two of them (previously only 8 and 28 taxa). The third was better recorded previously though records from 2000 onwards were only 35.

The Vicia orobus (Wood Bitter-vetch) that Carl found ten years ago was thriving with at least five plants in flower.

Steve spotted several Argent and Sable moths and there were both types of seal and a porpoise in the sea.
