Kent is a hive of activity insofar as wildlife and nature reserves are concerned. The RSPB have a number of reserves, together with which there are many locally designated nature reserves and wildlife areas. As with all rural areas - and also urban areas - leave them in the same condition as you would wish to find them. In particular, bear in mind that most forms of wildlife - even on public nature reserves - depend upon 'privacy' and respect for their continued survival.
