Keith Cohen

Keith Cohen has been a consultant ecologist since 2002, working at times as part of larger multi-disciplinary companies and at times self-employed, as now. A Full Member of CIEEM since joining in 2005, and a licensed bat worker since 1993 and a batworker trainer since 1997. Current projects include ringing and radio-tracking for population monitoring of Bechstein’s bats, research into surveys and monitoring of tree-roosting bats, and a range of commercial bat mitigation projects. Over the years, he has undertaken a broad range of ecological work including botanical surveys for windfarm developments and of SSSIs, fungal scoping surveys for the Scottish Foresty Alliance native woodland creation project, breeding bird surveys, and more. He also worked as a Countryside Ranger for 13 years in a role that involved botanical SSSI monitoring, bird census and providing bat advice (BRV) visits, and occasional ecology input to planning, as well as the usual practical, educational and interpretive work. That role also involved providing ecological training to varied groups including statutory bodies. Currently he is advisor to a community group on creation of woodland as bat habitat. No lighting expert, but with a broad awareness of ecological and practical aspects of lighting and how it may relate to habitat management, bat biology and behaviour. He is a more-or-less active member of several Bat Groups (Oxon, Wilts, North Bucks, Warks, Fife & Kinross).
