Matt is in Panshanger Park in Hertfordshire, seeing how an old quarry has become one of the best places for wildlife in the county. He also finds out that the park's many old trees are whole ecosystems in their own right, teeming with life. Sean is in Panshanger too, helping move a herd of English longhorn cattle to complete a 300-year-old vision for the park. This being Easter Sunday, Anita is on the trail of one of our favourite Easter snacks - the hot cross bun. She visits a restored, working watermill and helps grind the flour needed to make her Easter treats. Steve is in Buckinghamshire at Whitecross Green Wood nature reserve, looking for signs of spring. Down on Adam’s farm there is plenty of new spring life, but in among the new arrivals there’s also a note of sadness too, and Tom looks at how the fight to prevent a UK water shortage could hit food producers the hardest.
