Visitors to Oakwell Hall Country Park at Birstall next month are invited to find out what lurks beneath the surface of Oakwell's ponds.

"Children get the opportunity to do this kind of thing fairly regularly in school visits or special events," said park ranger Richard Aspinall. "But it's the kind of thing that a lot of adults would be interested in, too, so we thought why not give the grown-ups a chance?"

The afternoon of pond-dipping will be divided between two of Oakwell's ponds and visitors can expect to see anything from sticklebacks and frogs to diving beetles and dragonfly nymphs.

"It's the perfect opportunity for anyone who wants to learn something about pond wildlife," Mr Aspinall said.

The event, which runs from 2pm to 4pm on June 22, is suitable for families and children must be accompanied by an adult. There is no admission charge and equipment will be provided. Booking is essential as places are limited. Call (01924) 326240.
