Sammi Kinghorn returns to Cumbria to find out how young shepherdess Katie is doing now that she’s finished school for the year. The summer holidays are no time to rest, as Katie is hard at work tending to her livestock and catching up with maintenance jobs around the farm. They also visit a part of the farm where she has been working with the Woodland Trust on best practice for increasing biodiversity. Sammi also visits Lowther Castle, located just up the road, where a major project is underway to reconnect the estate with its natural environment, long since disrupted by Victorian engineering. It’s a project that involves large scale landscaping and the reintroduction of keystone wetlands species. Land management is also on the minds of the staff at nearby RSPB Leighton Moss where they are cutting back the extensive reed beds, part of the annual maintenance work to encourage a thriving habitat for the birds that draw people to the reserve.
