Habitat comments: "The area had been occupied by primary rain-forest until about 100 years ago, and then by secondary bush until houses were built on it quite recently. There are extensive areas of secondary bush near by, while within a few kilometres there is primary forest. The garden is surrounded by other, less-developed gardens, by roads and buildings, and by patches of secondary bush"
