Episode 3

John Craven enlists with firefighters in south Wales while Paul Martin discovers that the Rhondda Valley - one of the wettest places in the UK - is braced for around a thousand fires. In Malvern, sheep are nature's fire prevention officers but these animals have vanished from the valleys and the vegetation is running riot. Fire chief Craig knows how to tame the landscape. Paul also meets Becky Davies of Natural Resources Wales and discovers how to safeguard lives and creatures against the worst. Steve Brown's in a Kent garden which needs cat-proofing. Guy Barter, chief adviser to the Royal Horticultural Society has a few tricks but Prof Mark Fellowes, who has studied cats and their territories, reckons Steve could be on to a losing battle.
