Isle of Skye Quarry, Meltham

Isle of Skye Quarry, Meltham 

Friday 27th May 

A joint meeting with the Bradford Botany Group 

Leaders: Kay McDowell and Peter Burton 

 It was a windy but sunny day. We met on the side of the A635 for our visit to the old quarry, known officially as ‘Kaye Stone Pits.’ The A635 Holmfirth Road is often called the Isle of Skye road. The quarry is known as Isle of Skye quarry. It was labelled as ‘disused’ on the 1929 OS map, therefore it has been abandoned for about 100 years. The site is known by local botanists for being a botanically diverse site, but for most of the group it was their first visit. 

Some of our group were already finding interesting plants at the quarry entrance, including a flowering St Dabeoc’s heath possibly ‘Atropurpurea’ or a named cultivar ‘Irish Princess’, with striking pink-purplish flowers, a naturalised garden throw out. A wet flush running down towards the road provided a niche for common cottongrass (Eriophorum angustifolium) and bog stitchwort (Stellaria alsine). 

We walked through the entrance to the old quarry and spotted some golden-scaled male-fern (Dryopteris affinis ssp. affinis) growing on a cliff ledge, as well as a red-stemmed lady fern (Athyrium filix-femina). Then we encountered our first flowering orchid, a southern marsh-orchid (Dactylorhiza praetermissa). Pale lady’s-mantle (Alchemilla xanthochlora) was next, which is the most common species of native lady’s-mantle in this area. 

Our first sedge of the day were several pill sedge (Carex pilulifera). Then we looked at strange looking sedge with mixed congested male and female heads which confused us, but the leaves were green on top but glaucous below. It was later confirmed as glaucous sedge (Carex flacca). We came to the conclusion that the dry winter and early spring was producing odd looking plants. Oval sedge (Carex leporina) was found a little further on, and also after changing forget-me-not (Myosotis discolor) in flower. 

The site contains a good number of willow species, one of the first to gain our attention was eared willow (Salix aurita), followed by creeping willow (Salix repens). Then a mystery willow which turned out to be almond willow (Salix triandra). Across towards the cliff/quarry side was a group of willows including white willow (Salix alba), standing out from the grey willow (Salix cinerea) and goat willow (Salix caprea). 

Both marsh horsetail (Equisetum palustre), water horsetail (Equisetum fluviatile) were recorded in a shallow pool. Mike reminded me that one of its main identification features of water horsetail is that it has hollow stems and no branches. There was also a nice stand of spike rush (Eleocharis palustris). Common sedge (Carex nigra) was our next sedge, we looked at the stomata seen on the upper surface of the leaf seen through a hand lens. 

We found some yellow rattle (Rhinanthus minor) with dotted stems which we at first mistook for greater yellow-rattle (Rhinanthus angustifolius) as we thought we could see protruding stigma and possibly a horizontal lower lip but it was later confirmed as R. minor. It wasn’t greater yellow-rattle as that has larger teeth on the upper lip of the corolla and a pale inflated calyx. It seems there is quite a lot of variety within R. minor. 

We had our lunch sheltered from the wind, and spotted a small copper (Lycaena phlaeas). There were more southern marsh-orchids, and a red damselfly was also taking shelter. The next pond contained bottle sedge (Carex rostrata). I was persuaded to wade in and get a specimen to show the rest of the group as I was the only one wearing wellies. 

On the bank next to the pool we spotted another orchid species, this time it was common twayblade (Neottia ovata), growing with some typical moorland species including heather (Calluna vulgaris), crowberry (Empetrum nigrum), heath rush (Juncus squarrosus) and mat-grass (Nardus stricta). It was nice to see some small rosette leaves of common centaury (Centaurium erythraea), which was not quite in flower yet. 

Finally we saw some colourful flowering broom (Cytisus scoparius), a garden escape amongst another group of willows. Then we made our way back to our cars, feeling satisfied with our botanical finds. 

In early July botanist Michael Wilcox visited the site and found some more good records, including confused eyebright (Euphrasia confusa), confirmed Chris Metherell, the BSBI Euphrasia referee. Two others determined by Chris were arctic eyebright (E. arctica) and the hybrid between these two parents; (E. arctica x E. confusa). 

Michael also found twelve species of willow, including a purple willow (Salix purpurea ssp. lambertiana) and the hybrid between goat and eared willow (S.caprea x aurita).

Thunderbridge Meadows, Huddersfield

Thunderbridge Meadows, Huddersfield 

Friday 29th April 

Leaders: Louise Hill & Kay McDowell 

The purpose of this field trip was to record species in a nature reserve which we hadn’t previously visited, but had been told it was a good site. Thunderbridge Meadows is a Garganey Trust managed site. 

The site is in a picturesque setting and the weather was nice and clear day for our first meeting of the year. The first find of the day was bitter-vetch (Lathyrus linifolius) which had been spotted near our parked cars next to the bridge where Birks Lane meets Thunder Bridge Lane.

Meeting at the bridge, we decided to head for the nature reserve and walked adjacent to a beck. We examined a wood forget-me-not (Myosotis sylvatica) for some time, as we tried to figure out whether it was a garden escape or a native wood forget-me-not. We weren’t sure because there was also (Lamiastrum galeobdolon sp. argentatum) nearby which made us think twice about the forget-me-not’s native status. 

Soon we came across another alien species; house holly-fern (Cyrtomium falcatum) whilst looking at lady fern (Athyrium filix-femina). Then we saw some butterbur (Petasites hybridus), the flowers were quite pale and nearly white, maybe bleached by the sun, and not the usual pale pink. We looked at some silky lady’s-mantle (Alchemilla glaucescens) which had been recorded here before. Then we admired a gold scaled male fern (Dryopteris affinis ssp. affinis). 

We found a sunny bank to eat our lunch, it was pleasantly warm sitting in the sunshine. Whilst low to the ground we had a look for adder’s-tongue (Ophioglossum vulgatum) which had been recorded before but we couldn’t find it. We did find grassland species with no flowers yet as it was too early in the year, but with the help of Poland’s ‘Vegetative Key’ book we figured out the differences between burnet-saxifrage (Pimpinella saxifraga) and pepper-saxifrage (Silaum silaus). We thought it was burnet-saxifrage but there was also a chance it could have been pepper-saxifrage too. We also found common bird’s-foot trefoil (Lotus corniculatus) and devil’s-bit scabious (Succisa pratensis). 

We walked into the meadow, a damp grassland in the bottom of the valley where marsh orchid (Dactylorhiza spp.) had previously been recorded, however, we couldn’t find any leaves. We did find another lady’s-mantle, this time hairy lady’s-mantle (A. filicaulis ssp. vestita). We also saw some fine leaves which turned out to be common cottongrass (Eriophorum angustifolium) with a trigonomous tip. More leaves were examined and confirmed as smooth-stalked sedge (Carex laevigata), another tick on the ‘specials’ list. Wood horsetail (Equisetum sylvaticum) was another nice record. 

Walking up the field, an east-facing sloping bank which was becoming scrubbed over with bramble we saw great burnet (Sanguisorba officinalis). A seepage next to a stone wall produced yellow pimpernel (Lysimachia nemorum), opposite-leaved golden-saxifrage (Chrysosplenium oppositifolium), remote sedge (Carex remota), bog stitchwort (Stellaria alsine) and square-stalked St John’s-wort (Hypericum tetrapterum). 

It was 5pm so we decided to walk back to the cars. We were just saying we hadn’t seen any shield ferns when I spotted a likely candidate in a small stream, it was hard shield-fern (Polystichum aculeatum).

Denby Delf

Friday 24th June 

Leader: Kay McDowell 

We met on the lane just to the east of Upper Denby, which at about 600ft above sea level meant we were able to admire the fine views to the north over the local countryside. It was not quite as hot as the previous couple of days, but it was still warm, sunny and humid with a slight breeze. Skylark (Alauda arvensis), white throat (Sylvia communis) and yellowhammer (Emberiza citrinella) were seen nearby. 

We walked along the track to the nature reserve which is managed by the Garganey Trust, and headed towards the grassland where adder’s-tongue (Ophioglossum vulgatum) had previously been found. But it was a little late in the season and the grass too long, so we decided it would be better to come back next May. 

Next we came to some oak woodland cloaking a small valley, where we spotted male-fern (Dryopteris filix-mas), then Borrer’s scaly male-fern (Dryopteris affinis ssp. borreri). Further down the hill and under some trees we noticed a large hard fern (Blechnum spicant) and then to the left of us a very large lady-fern (Athyrium filix-femina). Near to this was a lovely golden-scaled male-fern (Dryopteris affinis ssp. affinis). 

We walked through the bilberry (Vaccinium myrtillus) down through more trees and into an area of grassland. Here we recorded oval sedge (Carex leporina), glaucous sedge (Carex flacca), devil’s-bit scabious (Succisa pratensis), marsh thistle (Cirsium palustre), tufted hair-grass (Deschampsia cespitosa) and compact rush (Juncus conglomeratus). However, we couldn’t find evidence of the pond on the map on the information board at the entrance to the site. But we did find tormentil (Potentilla erecta), zigzag clover (Trifolium medium) and bitter-vetch (Lathyrus linifolius). 

Making our way up the hill we found a bench at the top for lunch. Then we explored part of an old quarry and found rock stonecrop (Petrosedum forsterianum) on the side of a stone wall. I spotted a flowering grass which turned out to be brown bent (Agrostis vinealis). A lovely pink-flowering rose bush caught our attention; Sherard’s downy-rose (Rosa sherardii). Next, we went through the gate into another quarry and saw a barn owl (Tyto alba) fly off. We cautiously explored the old quarry and saw a red stemmed lady fern (Athyrium filix-femina).

Then went into the meadow, which is also part of the site. Lots of common spotted-orchid (Dactylorhiza fuchsii) made a nice scene. We examined a tall fescue (Schedonorus arundinaceus) or was it meadow fescue (S.pratensis)? The auricles weren’t large enough for tall fescue, so we looked for other characters such as hairs on the auricles, the number of spikelets on the lowest flower, and whether the leaves were rough or smooth, but we still couldn’t pin it down, maybe it was an agricultural variety?

It is always good to have a difficult puzzle to stretch our brains, and reminded ourselves that plants don’t read books!

Readycon Dean Reservoir, Denshaw

Readycon Dean Reservoir, Denshaw 

Friday 23rd September 2022 

Leader: Kay McDowell 

We met on the side of the main road A672 near Denshaw which is very close to the vice county boundary with Lancashire. The weather was warm for the time of year, a little breezy with a chance of showers. Our group of five aimed to fill in monad SD9912 which had only one record, may be we would even find a hay-scented buckler-fern (Dryopteris aemula)? 

We walked east along footpath towards the reservoir, going off the track to interesting looking habitat. We soon spotted some ferns including some common moorland species including hard fern (Blechnum spicant), lemon-scented fern (Oreopteris limbosperma) and narrow buckler-fern (Dryopteris carthusiana). We headed further down the slope to the beck to investigate an interesting looking bit of damp habitat where we found a nice group of species hare’s-tail cottongrass (Eriophorum vaginatum), opposite-leaved golden-saxifrage (Chrysosplenium oppositifolium) and , as well as the rounded leaves of marsh violet (Viola palustris) and sedges including common sedge (Carex nigra) common yellow-sedge (Carex demissa), star sedge (Carex echinata) and then velvet bent (Agrostis canina) with its leaves trailing down a small waterfall. 

After lunch we headed towards the spillway and spotted black spleenwort (Asplenium adiantum-nigrum), and again on the northern dam head with maidenhair spleenwort (Asplenium trichomanes). We walked along the cobbles on the edge of the reservoir, the water level was very low due to the drought. Mike spotted a small unusual form of lady-fern (Athyrium filix-femina) with divided pinnules which he described as a variety called ‘Cristatum’. 

Asplenium adiantum nigum  & A trichomanes 

In the drain into the reservoir we spotted Borrer’s scaly male-fern (Dryopteris ssp. borreri) with identification features including square-ended pinnae and ‘chanterelling’ sori. In a pool at the base of a quarry rock face we recorded bog pondweed (Potamogeton polygonifolius) and round-leaved crowfoot (Ranunculus omiophyllus). 

We headed towards the Pennine Way to explore a pond marked on the map, but we couldn’t see any aquatic vegetation, so we headed back over the moor to rejoin the footpath. Passing the dam head wall someone spotted a couple of small ferns growing in the cement which turned out to be rustyback (Asplenium ceterach), which made us all very happy. It was the first record for rustyback in hectad SD91! During the trip we recorded twelve ferns.
