Gangamoola is a part of the Kudremukh biodiversity sub-cluster of the Western Ghats which has been nominated to receive the designation of a World Heritage Site by UNESCO. A survey conducted by the ornithologist Davidar in 1980 recorded 107 species of birds in the Kudremukh-Aroli-Gangamoola tract. The presence of a large number of bird species is due to trees like Myristica dactyloides that are favoured by birds.
