Rusty-Back Fern, Asplenium ceterach |
Whilst looking for Dipper Cinclus cinclus nests and colour ringed birds in south-west Shropshire close to Chapel Lawn, we came across a small bridge ,covered in Rusty-back Ferns Asplenium ceterach and Maidenhair Spleenwort Asplenium trichomanes. The rusty-back fern is a lover of alkaline rocks, meaning the local limestone is perfect, whilst the maidenhair spleenwort has a large number sub-species of subspecies, some of which are calcifuges whilst others a calcicoles.
In the end we didn't see any Dippers on this stretch of river but we did go on to catch and ring a 6M Tawny Owl Strix aluco (my 109 species ringed) and a nice brace of Jack Snipe Lymnocryptes minimus, probably the last of the year and some cracking views of Tree Sparrows Passer montanus up on the Ceri ridgeway.
