Add on to the previous post. If you are in any way interested in trees you should definitely try and get a hold of a book by Colin Tudge, 'The Secret Life of Trees'. Colin is an extremely well informed science writer and the book is a really in depth look at trees and how they are related to each other and was aptly described by a writer for the Financial Times as 'A love letter to trees'. I borrowed the book from my good friend Paul (read his comment on the previous post to discover his love for trees) and I have not as yet finished the whole book, but I have thoroughly enjoyed it thus far. It is not a 'sit down and read' book because it has a lot of information to absorb, but it is great to ave lying around to read a section at a time.
Tudge has another book out on birds which follows in a similar fashion as the tree book. I will get my hands on it soon and hopefully put a short summary or review of some sort.
