SN60I Cwmcerdinen verges

It surprises me sometimes how many species you can find in the most unlikely looking spots. Yesterday I stopped at the cattle grid at the entrance to the village as there was a bit of tarmac and flushed gravel to look at before I headed on to my target of the riparian woodland. In the end I spent nearly an hour in this area where I found a base-rich seepage dominated by Pellia endiviifolia and Dicranella varia as well as a section of verge with species such as Solenostoma gracillimum under a mat of Wahlenbergia hederacea. Plus there was some nice wet heath adjacent to the road with all the commoner Sphagnum spp., etc. On a few occasions recently I've found non-fruiting Fossombronia, which is very frustrating! Hoping to take Alfie for a ‘walk’ in the next tetrad today...

  1. Those gravelly roadside habitats are fascinating Barry. It's the same with gravelled forestry roads, particularly when limestone has been used. In NPT, where there are no natural limestone outcrops, these forestry tracks support calciphiles like Trichostomum crispulum, Campyliadelphus chrysophyllus, Didymodon ferruginous and Jungermannia atrovirens, and of course (albeit very rarely) Distichium inclinatum. Some surprising flowering plants like Gentianella amarella and Euphorbia exigua also find a home there. It seems to me that looking at bryophytes allows you to see in another way, often transforming 'ordinary' places into something rather special.

  2. NPT certainly has the most extensive network of such tracks locally, providing a wealth of opportunities for some interesting species. I guess this produce a confusing picture when trying to correlate distribution patterns with geology.

  3. These excellent little patches of habitat are potentially found almost throughout inland Glamorgan/S Wales, but most are inaccessible. It's great to have those which we stumble across properly documented. There are some super lane banks in N-central Carms with Anthoceros, Phaeoceros, Fossombronia spp etc - all in very 'ordinary' areas.
