27/05/25 National Parks, impact of dry weather, plastic in insects.

All week we're looking at National Parks, last week the Supreme Court ruled that wild camping on Dartmoor is legal. Some areas, however, are dealing with anti-social behaviour and 'fly camping'. We talk to Kevin Bishop CEO of Dartmoor National Park who also sits on National Parks England about the challenges.

The prolonged dry spell has had affected the growth of crops and water levels in rivers and reservoirs, but what about wildlife? We ask the British Trust for Ornithology what impact it's likely to have on wading birds and also discuss their new report which examined the impact of bird flu on wild birds like swans and barnacle geese.

Plastic pollution is contaminating insects at the base of food chains, raising fresh concerns about the long-term impacts on wildlife, according to a new study by the University of Sussex. Researchers have discovered fragments of plastic in a wide range of invertebrates, which are prey for small mammals like hedgehogs. Polyester fibres, commonly shed from clothing, were the most frequently detected type of plastic and scientists think it comes from treated sewage sludge used to fertilise fields.
