Children's television presenter Radzi Chinyanganya is a special guest at Pensthorpe Natural Park, near Fakenham, tomorrow, when he is helping to judge an art competition as part of its annual Wild About The Wensum event.

Mr Chinyanganya will also be walking along the river to try and spot a water vole.

Now in its ninth year, the event, hosted by Pensthorpe Conservation Trust, raises awareness about the Wensum Valley conservation projects and this year will help Britain's fastest declining mammal, the water vole. There is a reduced entrance fee of £2 per person for the event.

The Wensum Valley is designated as a special area of conservation and is one of the UK's most important chalk river habitats.

Activities running throughout the day include spotting wildlife and educational talks on river animals and about the water vole.

There will also be bike tours, a bee hive, crafts, bone identifying, bird feeder and badge making and more than 28 exhibitors including the RSPB, Norfolk Wildlife Trust and Norfolk Conservation Corps.

Mr Chinyanganya, who presents the long-running children's television show Blue Peter, said: 'I am excited to be in north Norfolk and am looking forward to exploring Pensthorpe Natural Park and meeting some young nature enthusiasts to go Wild about the Wensum.'

Chrissie Kelley, head of species management at Pensthorpe Conservation Trust, believes the event is an important date in the diary.

'Our Wild about the Wensum event is a great way for children to visit us here at Pensthorpe Natural Park and learn all about wildlife in a fun, interactive way,' she said.

'It is a really popular event and we also get lots of Brownies and Cubs who love getting close to nature and it's great to see future generations appreciate the natural world we live in.'

Wild About The Wensum is from 10am to 5pm tomorrow.
