Botanical Field Weekend August 2021

Gilfach and Abbey Cwmhir home grange

The weekend of 14 and 15 August was dedicated to looking at the botany of the old farmstead, Cwmffwrn, in the home grange to Abbey Cwmhir.  However as an introduction to both upland and species of traditional farms, Saturday was spent at the Gilfach reserve, an old farm owned by Radnorshire Wildlife Trust.  Along with the unimproved traditional pastures and meadows, we looked at species of riverside, woodland edge, bog and heathland. Highlights were swathes of the beautiful Betonica officinalis Betony and the facinating Narthecium ossifragum Bog Asphodel and Succisa pratensis. Devil’s-bit Scabious. We also examined, for example, the features which differentiate the three heaths: Calluna vulgaris Heather, Erica cinerea Bell Heather and Erica tetralix Cross-leaved Heath.

On Sunday following an introductory talk on archaeobotany, we walked through bog, acid grassland, willow carr and bracken to the various sites where medieval farm buildings once stood.  The moorland plants had long since taken over, but it was interesting to see what now grew there: various sedges Carex species, Nardus stricta Heath Grass, Molinea caerulea Purple moorgrass, Juncus squarrosus, Heath Rush and Pedicularis sylvatica Lousewort.  In wetter places we found the lovely Achillea ptarmica Sneezewort, Mentha aquatica Water Mint and Potamogeton polygonifolius Bog Pondweed.  

Towards the end of the walk, we explored the remains of an old farmhouse with some remaining walls.  Ferns love such sites and many encouraged by the old lime mortar. We found Polypody vulgare Common Polypody, Asplenium trichomanes Maidenhair Spleenwort, Dryopteris dilatata Broad Buckler-fern and Dryopteris filix-mas Male Fern which are all found commonly growing on and around old buildings. The ruderal, Chamerion angustifolium Rose-bay Willowherb was growing in abundance along with Ribes uva Gooseberry, Urtica dioica Nettle, the latter two species long outliving former occupants of such buildings.
