Nature's Calendar - Series 1 - Summer: Woodlands

Chris Packham presents a guide to the best places to see wildlife this summer. In the woodlands of Surrey, he looks for the Holy Grail of butterflies - the purple emperor - and provides some unusual tips to attract a whole range of woodland butterflies. Meanwhile, Mike Dilger goes to Castle Eden Dene in the North East for one of the best woodland walks in the country, and Sanjida O'Connell gets close up to the red kites of Rockingham Forest.
