There are a variety of suitable places in gardens which you could find grass snakes. Compost heaps are often used as egg laying grounds due to their warmth which acts as a natural incubator. Garden ponds are used as foraging grounds for their food, as are any streams or ditches that may run through or close to your garden. Banks, mounds and rubble piles are used as areas to bask in, and they can also act as hibernation sites. Areas of short and long grass interspersed will often be used for foraging (long grass) and basking (short grass).
