Sheep farmers have noticed the season for blowfly strike - where maggots hatch out in the fleece - is getting longer. Now research done by vets and scientists is linking it to changing weather patterns. They've produced a report advising farmers on how to manage the problem.

Charlotte Smith heads to Surrey to investigate a disease that's killing English oak trees. Defra has given scientists 拢1.1m to research the causes of Acute Oak Decline, which they suspect may involve a native beetle.

And all this week we're looking at the challenges facing country estates. Charlotte talks to Harry Cotterell, president of the Country Land and Business Association, about whether farming is enough to keep big estates going in the 21st century.

Presented by Charlotte Smith. Produced by Anna Jones.
