Richard Mabey is our own Green Man. Who else has explored the world of British plants (and other countryside matters) so knowledgeably with such persistence and sheer enthusiasm, drawing so many of us along with him? Who else can write about nature with such fluency? In nearly twenty books, including such tours de force as his majestic survey of our native botanical riches, Flora Britannica, Mabey has done as much as anyone to celebrate and define our natural history. I’m certainly prepared to grant him as much latitude as he wants when it comes to pursuing a thesis.
