In the fourth 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. Members of the British Bryological Society study mosses and liverworts and their travels in search of these delicate and very beautiful plants take them into some of the most remote and spectacular landscapes. Brett joins expert bryologists Mark Lawley and Sam Bosanquet in mid-wales where they find a liverwort called Spotty Fingers, discover the delights of "grotting" and talk about their editorship of a new photographic field guide to mosses and liverworts, an achievement of which the Society is very proud.

Presented and Produced by Brett Westwood.
