Flora of the Applecross peninsula mountain range, The Scottish Highlands

Introduction

During an exploration of Northwest Scotland, me and my brother found ourselves visiting The Bealach (Bealach na Ba) of Wester Ross in the Scottish Highlands. Along winding roads through mountainous terrain and magnificent mountain views we found ourselves at the Bealach na Ba Viewpoint. This area had a carpark so we decided to park there and explore the nearby area to see what plants we could find. I was very keen to know what lived here as I've never had the opportunity to see alpine flora in the wild before. What I discovered was an interesting and diverse habitat, with equally diverse and interesting plant communities. The area consisted of moorland, littered with rocky terrain, bogs and ponds.

Dry Alpine Flora

The habitat consisted of acidic soil and rocky outcrops. There were many species of typical moorland plants such as: Common Heather (Calluna vulgaris), Cowberry (Vaccinium vitis-idaea) Bilberry (Vaccinium myrtillus) and Crowberry (Empetrum nigrum). These species are quite typical on moorlands, however I felt they were still worthy of mentioning. I also found many other alpine plants within the habitat, many of which were located on the rockier areas where the ground possessed better drainage. Notable species include Dwarf Willow (Salix herbacea), Alpine Lady's-Mantle (Alchemilla alpina), Mountain Everlasting (Antennaria dioica) and Alpine Azalea (Kalmia procumbens). These species were common here, however became less common on the boggier areas. There were also other species in the dryer areas such as Woolly Fringe-Moss (Racomitrium lanuginosum), Urn Hair Moss (Pogonatum urnigerum) and the occasional Hard Fern (Struthiopteris spicant).

Bog Flora

Within the area there were also areas of bog, many of which were located around alpine pools. These areas were primarily dominated by grasses and bryophytes, with many colours and species of Sphagnum Moss being present. I saw various shades of green, orange and red. These sphagnum moss species formed extensive matts, which store water and ensure boggy conditions within the habitat. Between these patches of sphagnum moss I also found other species of bryophyte present such as Bog Haircap Moss (Polytrichum strictum), Stairstep Moss (Hylocomium splendens) and the unusual looking Purple Spoonwort (Pleurozia purpurea). The habitat also consisted of a lot of Deergrass (Trichophorum cespitosum), Common Heather (Calluna vulgaris), the occasional Bog Asphodel (Narthecium ossifragum) and Common Butterwort (Pinguicula vulgaris). The rarest organisms I found in the bog were Alpine Clubmoss (Diphasiastrum alpinum), Heath Spotted Orchid (Dactylorhiza maculata) and Fir Clubmoss (Huperzia selago).

Lichens and Fungi

Although these are not plants I'd still like to list them as I felt they were significant. I didn't see many lichens or fungi in this habitat, although I was mainly focusing on the plants. I did manage to find an interesting looking lichen that was nestled in some moss, which I believe to be Thorn Lichen (Cladonia uncialis). I also found what I believe to be Lichen Agaric (Lichenomphalia ericetorum), which was sprouting out from some sphagnum moss. My brother also found what he believes to be Bog Bell (Galerina paludosa).

Conclusion

The area near to the Bealach na Ba Viewpoint within the Applecross peninsula mountain range is clearly a very biodiverse habitat, which hosts both dry alpine and boggy conditions ensuring a diverse array of species can live there. Although I encountered many species, I can't help but feel there are far more species there than I had encountered in my exploration of the habitat. It was a fascinating and enjoyable experience to see so many plants that I have never seen before. I especially enjoyed exploring the sphagnum bog and feel I learnt a great deal from my time there. I don't know if I'll ever return to this place, but if I do I'll be sure to take far more photographs!

Exploring the Ecology of the Wetley Moor Common SSSI, Staffordshire.

Introduction

I have been visiting the SSSI nature reserve known as Wetley Moor Common in Staffordshire to observe what species may be present there. The SSSI consists of both dry and wet lowland heath habitat, with wet heathland being quite rare. Wetley Moor Common makes up 10% of Staffordshire's heathlands. The site also possesses patches of improved grassland and woodland, however those are not the reasons for Wetley Moor Common's SSSI status.

With both dry and wet heathland being unusual habitats I decided to try and do some research into what species might live there. I strangely found very little information available online... I did some further research and learnt that back in 2023 the habitat was discovered to be within a "degraded" state, which means it requires correct habitat management to help restore it ecologically. Regardless, I thought it would be interesting to visit the site and record what species I could find there as there wasn't much information available online.

The Dry Heathland Flora

The dry heathland lies on coarse-grained sandstone and possesses sandy soil. This sandy soil provides good drainage and drier conditions for flora. I climbed a hill and saw some traditional heathland plant species present: mainly Common Heather (Calluna vulgaris), European Billberry (Vaccinium myrtillus) and the occasional European Gorse (Ulex europaeus). The habitat also possessed a few spaced out English Bluebell (Hyacinthoides non-scripta), which was surprising. I had always seen bluebells in woodlands, but never anywhere else. I also noticed in certain places there was an extremely high amount of Bramble (Rubus sp.), which swamped a lot of the other heathland plants.

The Wet Heathland Flora

The wet heathland lies on coal measures and shale, which results in waterlogged peaty soil. It is also colonized by Common Heather (Calluna vulgaris) and European Billberry (Vaccinium myrtillus). Due the habitats degraded state there is only a small amount of Sphagnum Moss (Sphagnum sp.) present, which grows under the shelter of a wooden bridge. I found some other wildflowers within the wetter soil conditions such as Cuckoo Flower (Cardamine pratensis) and Meadow Buttercup (Ranunculus acris). The wet heath also possesses many species of grass such as Purple Moor Grass (Molinia caerulea), Hare's-Tail Cottongrass (Eriophorum vaginatum) and Wavy Hair-Grass (Avenella flexuosa). I encountered many other grass species, but I'm not good at grass ID so I didn't record them.

Beetles

When I first entered the reserve I quickly noticed the remarkable array of beetles present. Just at the entrance where the improved grassland, forest and heathland meet, I managed to find many species nestled within the bramble and grasses. One of the most noteworthy and numerous I encountered was the 7-Spot Ladybird (Coccinella septempunctata), which has a very strong foothold in this habitat. There was simply so many 7-Spot ladybirds that I stopped photographing them after a while. I did encounter the occasional invasive Harlequin Ladybird (Harmonia axyridis), however they were nowhere near as prominent. I must have easily found over thirty 7-spot Ladybirds, but I found only two Harlequin Ladybirds. A few more beetle species I found include the: Tortoise Beetle (Cassida vibex), Alder Leaf Beetle (Agelastica alni), Hawthorn Leaf Beetle (Lochmaea crataegi) and Paradromius linearis.

Butterflies and Moths

Butterflies I spotted on my exploration of the habitat included various Orange-tip butterfly (Anthocharis cardamines) and a single Green-veined White butterfly (Pieris napi). Both species of butterfly utilize the cuckoo flower as a host plant for their caterpillars. I had seen a lot of cuckoo flower growing in the wet heathland so there was plenty of habitat for them to lay their eggs. I also spotted a Speckled Wood Butterfly (Pararge aegeria) and a swarm of Green longhorn Moths (Adela reaumurella). The Green longhorn Moths were swarming around a juvenile Oak Tree and quickly retreated out of range of my camera after I took a single photograph.

Other Bugs

Within the habitat there were dozens of other insects present. Of the species I did manage to identify I encountered multiple Arched Spearhorn Hoverfly (Chrysotoxum arcuatum), which are commonly associated with heathlands and moors. I also encountered Black-striped Cranefly (Tipula vernalis), which has a preference for the marshy habitat provided by the wet heathland. The Gorse Shield Bug (Piezodorus lituratus) was also found in close proximity to a Gorse bush.

Birds

During my exploration I encountered Eurasian Jackdaws (Corvus monedula), Eurasian magpie (Pica pica) and a Robin (Erithacus rubecula). These birds were generally very shy and fled when I approached to get into range to photograph them. I did not focus much of my time on the birds present, however I've heard that the reserve supports various other species such as Reed Bunting (Emberiza schoeniclus), Linnet (Linaria cannabina), Meadow Pipit (Anthus pratensis), Whitethroat (Curruca communis) and Grasshopper Warbler (Locustella naevia).

Conclusion

In conclusion I really enjoyed visiting the Wetley Moor Common SSSI. When I read that the habitat was in a "degraded state" I assumed that perhaps there wouldn't be many species there to observe, but that was not the case. I got to see a lot of interesting plants and invertebrates that I have never seen before. I also feel as though I have a better understanding of the habitat in general now. Reading about it was one thing, but actually going out there and seeing it for myself was another entirely. I plan to visit again sometime as I'm sure there is even more interesting species there that I've yet to observe. Speaking of interesting... I also found my first Dandelion (Taraxacum sp.) exhibiting fasciation right by the nature reserve car park.
