Pembrokeshire has tremendously diverse habitats, including dramatic coasts, steep-sided valleys, the tors of Mynydd Preseli, and 'Mediterranean' hotspots around Stackpole and Manorbier. The Mosses and Liverworts of Pembrokeshire celebrates the county by looking at the distribution and behaviour of the mosses, liverworts and hornworts that give each habitat its own subtly different appearance, from the hoary grey of Coscinodon on coastal shale, through dark reds of Frullania-covered rocks and the pale green of streamside Trichocolea, to the striking orange and red of the bog-mosses and Scorpidium of Preseli. Introductory chapters include a history of bryophyte recording in the county, detailed examination of the key species in each habitat, and comparisons with adjacent counties in west Wales and with more distant but ecologically similar north Wales and Cornwall. Each species account is written in a colloquial style, drawing on the author's experience with the plants being described both in south Wales and further afield. Recording for the Flora started in 2000, since when the author has seen all but 26 of the 534 bryophyte species recorded in the county.
