Wildlife on Therfield heath

Martin Johnson runs a blog (roystonwildlife.blogspot.co.uk), which includes his sightings on Therfield Heath as well as his 'Local Patch', formed by the triangle of Royston and the villages of Reed and Therfield. Look under the index of 'Local Sightings' to see a record of his sightings going back a couple of years. His web site www.roystonwildlife.com includes a brief overview of Therfield Heath and its wildlife on the first few pages.
