Hibernacula project

Our native newts, frogs and toads are important predators of a wide variety of pest insects, as well being important prey for other species. Habitat loss has had an extremely detrimental effect on amphibian populations. So with winter fast approaching the FOGW took the opportunity to build a hibernacula close to one of the three ponds within the Griffin Wood site.

Hibernaculums are underground chambers that amphibians and reptiles can use in winter to protect them from predators and the cold. They can be made from piles of rubble, rocks, logs and earth banks.

Starting work on the Hibernacular

After a suitable site had been chosen a trench was built and a drain pipe fitted. The trench was then filled with sand and rubble to aid drainage.

Lots of rocks, old logs and old drainage pipes were then piled into a mound to create crevices and hiding places with bits of pipe used to create south facing entrances.

During the morning, to give our backs a rest we attended a training day at the Leaf centre (Top Tree Tips with George Pilkington). George had shown us examples of trees planted with and without grass growing around their bases. and also shown us the benefits of mulching around the trees (see:- the Nurturing-Nature link for more info). The results spoke for themselves, so we decided to use the opportunity to remove some of the grass around the young Oaks in the vicinity and use these turfs and clods to cover our Hibernacula
