Trefloyne

The old limestone quarry at Trefloyne near Penally in south Pembs is in the process of being infilled with imported soil and sandstone. The soil must be coming from somewhere interesting, as one of the piles near the entrance had small patches of Didymodon acutus s.s and Didymodon tomaculosus on it, alongside Microbryum rectum and various common species. The two Didymodons were also growing together in the rut on the disturbed quarry floor pictured above. More atypically, a small patch of tomaculosus was also growing amongst Trichostomum crispulum on the limestone chip track into the northern part of the quarry. That's now four sites for it in Pembrokeshire, which suggests that it doesn't deserve its Section 7 status. 

The locally-scarce Pohlia lescuriana was beginning to fruit among commoner ruderal species such as Bryum klingraeffi on the disturbed clay here. Some shaded limestone boulders on one edge of the quarry, not yet disturbed, had another locally-scarce moss in the form of Platydictya jungermannioides. Gymnostomum viridulum was fruiting below the exposed limestone here - this is one of two locations in the county where it seems to do so regularly.
