Sam Bosanquet is a naturalist and ecologist based in south Wales, who has been recording a wide range of plants and animals – particularly mosses, liverworts, lichens, fungi, plants, moths and birds – for more than 25 years. He is Bryophyte Recorder for Carmarthenshire, Monmouthshire and Pembrokeshire; Moth Recorder for Carmarthenshire; Micro-moth Recorder for Monmouthshire; and until recently was Liverwort Recorder for Britain and Ireland. He is the moss, lichen and fungus specialist for Natural Resources Wales, and co-authored the Guidelines for Selection of Biological SSSIs for these groups. He works with NRW colleagues on wetland and grassland habitats, giving him an intimate working knowledge of the National Vegetation Classification. One of his particular interests is ammonia pollution and its impact on biodiversity. He is presently running the 220 acre Old Lands grassland restoration project in Monmouthshire, increasing the abundance of flowers and flowering shrubs in a wood pasture landscape where more than 3000 different species of animal, plant and fungus have been recorded.
