Do tree frogs make themselves heard during IVN walk?

On Thursday, June 6, IVN De Maasvallei organizes together with KBO a nature walk at De Vilt in Beugen. Brabants Landschap has done a lot to create a paradise for the tree frog here. It seems he really feels at home here and who knows, he might even make himself heard during the walk....
Apart from this, De Vilt, part of the UNESCO site De Maasheggen, is and remains a beautiful nature reserve anyway. It suffered greatly from drought in recent years. Has the rain in the fall and winter been enough to recover and can the participants of the walk already see some of that?
The two-hour walk starts at 1:30 p.m. at the information board at Moerbaan, Heiveldsestraat in Beugen. Non-members are also welcome. Info: Piet Schoenmakers, tel. 0485-520876. Register through the website of IVN De Maasvallei.
