I've just got ther new BDS Field Guide to Diseases and Conditions of Deer in the UK. it cost only £12 off their website and it's really good...well worth the money.
i think that it replaces the old disease cards and really has moved on a lot. instead of the 8 or 10 cards as it was then, it's now a waterproof, tearproof booklet of about 70 pages and covers all the diseases and conditions of deer.
A great reference guide for the field. Anyone else ssen it?
