50 years ago, at a good site the Grass snake could be seen in large numbers. Unfortunatly now, because of a loss of habitat and food it has become increasingly rare. Grass snakes often live near to water. They are good swimmers and frogs feature highly in their diet.
In England hibernation is between October and March. Mating takes place between April and May though the female, at best will only breed on alternate years. 4-10 eggs are laid and hatch around the end of August and the beginning of septemeber.
The life span is up to 25 years.
