Kent has a valuable fauna and flora, some of which occurs nowhere else in the country. It recorded 85 UK Biodiversity Action Plan priority species in the Kent Red Data Book in 2000. Even if you do not have any rarities on your holding, it is worth finding out more and there are good sources of information.
The Kent Biodiversity Action Plan (BAP) is probably the first place to look. This document sets out to conserve, enhance and restore biodiversity in Kent and as such is a contribution to the national targets of the UK BAP. As well as broad habitats and priority habitats to conserve in Kent, it sets out a Priority Species list of fauna and flora for the county.
The Kent BAP species list was put together by the Kent & Medway Biological Records Centre, which is itself a valuable biological and environmental data resource. KMBRC role includes the collection, collation, safe storage and dissemination of environmental data which is available to local authorities and planners, industry, conservation organisations, academics, local naturalists and the general public.
The National Biodiversity Network is a website inventory showing species in your area on interactive maps, you can use it to explore species distributions, whole datasets, protected sites and habitats.
For specific information on birds, the Kent Ornithological Society Tetrad Atlas Status Maps are very useful, giving breeding and wintering bird coverage and species richness. The RSPB Volunteer & Farmer Alliance (V&FA) can provide farmers with a survey undertaken by RSPB volunteers of the birds breeding on their land.
Finally, don’t forget that Kent Wildlife Trust is able to provide a wide range of information and advice on species in Kent.
