Mycenae Gardens offer many different habitats where the wildlife can feed, hide, struggle, flee, court, breed, raise their young and shelter.

Within the gardens there are old trees, young trees, tall and short trees, dead trees, bushes, scrubby undergrowth and tangles, and areas without trees, but with bug-rich grass turf. These are home to countless small crawling and wriggling creatures, some of which turn dead wood, leaves and grass into productive soil or waste, some of which prey on the plant eaters, all of which are food for birds, which are easily visible to people, or the bats which few people notice at night.
