However, it"s not all about the pond itself – the rest of the garden habitat surrounding any body of water is also worth considering. The Wildlife Trusts suggest maintaining a patch of unmown grass near the pond for young amphibians and butterflies and perhaps a compost heap, which animals such as grass snakes may lay their eggs in. Also, animals might find it easier to get into the garden in the first place if the habitat is bordered by hedging rather than walls or a solid fence.
