Let there be light
Frogs hibernate at the bottom of ponds and need to take in oxygen through their skin. Make sure your pond plants are getting enough light to photosynthesise – and that you have plenty of them. If your pond freezes, sweep away any snow that settles on the ice. By all means make a hole in the ice, but research by the Freshwater Habitats Trust has revealed that this is not a ‘quick fix’, because oxygen diffuses slowly.
Amphibians hibernate anywhere damp and sheltered. Take care not to disturb them when carrying out garden maintenance over the winter.
Log piles, piles of leaf litter and compost heaps make ideal winter refuges for amphibians – the best are damp, sheltered and provisioned with slug and insect prey. Amphibians prefer small spaces, so put some loose soil or wood chippings among logs and rocks.
For frogs, bury a perforated, used growing bag in a shallow trench, cover with grass clippings then add a layer of leaves and twigs. Amphibians will also be attracted to simple piles of wood, or rocks covered with soil or turf.
Keep it cosy
Frogs like to bury themselves in the debris on a pond bed, so make sure that yours isn’t too ‘clean’ – add some soil if necessary.
