In the third of this series of five programmes exploring the aims and enthusiasms of their members, Brett Westwood gets to the heart of our natural history societies and finds that here in the UK they are in surprisingly good shape. In 2011 the London Natural History Society celebrates 70 years of studying one place, Bookham Commons in Surrey. The results of the findings, which include purple emperor butterflies and 1800 species of beetle, have influenced the way the National Trust manages the site for people and wildlife. Brett joins a beetle hunt with Stuart Cole of the London Natural History Society and Ian Swinney from the National Trust and discovers the jewel-like mint leaf-beetle as well as the value of keeping a donkey on site.
Produced and Presented by Brett Westwood.
