Aarey is contiguous to the Sanjay Gandhi National Park (SGNP) and exhibits much of the same biodiversity. The terrain consists of scrub forests, hills, rocky outposts, ponds and grasslands.
Aarey is home to a large variety of flora and fauna and teeming with wildlife. A study on the biodiversity in the colony by ecologists Rajesh Sanap and Zeeshan Mirza found that the colony is home to 76 species of birds, 86 species of butterflies, 13 species of amphibians, 38 different types of reptiles, 19 spider species and 34 different types of wild flowers. In a report, which was also submitted to the state government, they stated that colony also has a wide variety of mammals including leopards, spotted deer, rusty spotted cat, jungle cat, civets, the sambar deer and barking deer.
Such a wide number of different species of birds, mammals, insects, amphibians and reptiles make Aarey a biodiversity hotspot. What’s more, two species of spiders, unknown to science, have been discovered here and some species which were thought to have been lost, have been rediscovered after 100 years in Aarey. This area is also home to three Schedule I species which receive the highest level of protection under the wildlife protection act – the leopard (Panthera pardus), the rusty spotted cat (Prionailurus rubiginosus) and the Python (Pythonidae).
Some of the species endemic to Aarey include:
Amphibians : Euphlyctis cyanophlyctis, Uperodon systoma, Microhyla ornata, Ichthyophis bombayensis
Butterflies and Moths :
Atlas Moth Attacks atlas, Common Jezebel Delias eucharis.
Reptiles : Lygosoma lineata, Geckoello collegolensis, Boiga forsteni This is just the beginning. A team of researchers have discovered two new species of spiders in Aarey strengthening the case to protect Aarey not only for the many ecological and social services it provides to Mumbai but also in the interest of science
