When Brett Westwood began a wildlife diary at the age of 15, little did he think that he'd still be writing notes, nearly 40 years later about the same local patch in North Worcestershire.
In this programme, Brett visits the valley. Since Brett started visiting his local patch, the landscape here has been changed more radically than any other area in the patch, not as a result of management, but of nature taking its course. The valley is a sandstone dip between two horse pastures and its steep sides have deterred any cropping or grazing.
