Caz Graham visits two Nature Reserves in Cumbria to find out what happens on wildlife reserves in winter and meets the people working away to maintain these conservation areas.

It's cold outside: many birds have flown south for the winter and the smaller mammals have gone into hibernation, but there is still life to be found on nature reserves, if only in the form of teams of conservationists maintaining the area for next year's visitors.

Caz heads first to Foulshaw Moss, an expanse of peat bog that has been restored over the past decades to ensure the peat continues to grow and squelches her way around the wet habitat.

She then heads to Roudsea Nature Reserve to find a team at work preparing the woodland for the tiny, hibernating dormice that make the area their home.
