"Spring at last! And once more you can sense the sap rising in the nature conservation world. All around are little messages of hope and confidence, 'calls' for action as upbeat and predictable as the little birds singing in the tree-tops. For example, the Wildlife Trusts' call this season is for 'an end to road schemes and housing development that damage wildlife'. Well, cock-a-doodle-doo to that, we must all agree."
