Gardens and animals don’t mix. Gardens by the open Forest need to be securely fenced, or animals might break in and cause all sorts of trouble. One pony had to be rescued by the fire brigade after walking onto the green plastic cover of a swimming pool, probably thinking it was grass.
Some garden plants are poisonous to animals, so people need to be careful about what they plant close to the Forest, as hungry animals will try nibbling anything that grows near a fence. Garden waste should never be dumped on the Forest, as it can be poisonous. Grass clippings are particularly dangerous for ponies and can kill them.
