Summary: Brett Westwood presents. For the first time in 400 years European Cranes are free-living on the Somerset Levels. Saving Species is live in the wetlands to witness this important landmark. And we get into citizen science. The Open University with OPAL (open air laboratory) launch a hedge row survey for us to conduct and we join a "BioBlitz" in Dorset - all lay people oberserving and recording and filing the data on public record. But is it of any real value? We ask the questions.
