The RSPB is a nature conservation charity with a focus on birds, but it works to create habitats for a wide variety of plants and animals (mainly in the UK, but overseas too). If you're lucky, maybe you'll find a shop selling these neat little badges for a quid each. The market stall I buy my bird seed from has a box of them.

A few I bought for myself and some were gifts, but I tend to mostly collect the badges of birds, plants and animals that I've personally spotted. Anyway, I think they're fun to collect and buying one'll do nature a solid.
