This documentary focuses on the preservation efforts of the Yorkshire countryside made by Yorkshire Naturalists' Trust founded in 1946 and now known as Yorkshire Wildlife Trust. The film outlines the problems that project developments of roads and buildings are destroying the surrounding countryside and its skyline. Information is given about preservation and the various nature reserves in Yorkshire that the public can visit and to which they can donate funds. Explanations of the different seasons, the wildlife and plant life found in those seasons, and the effect that building development has on the countryside are strong themes in this film.
This film is one of several from the Parkin collection. It depicts family activities in the countryside on their visit to Castleford, a trip to the seaside and a birthday party.
