Largest non-governmental organisations, Bombay Natural History Society conducted a study 77 new species of butterflies has found in the ecologically sensitive forest of hill station Matheran in Mumbai. More than 140 butterfly species founded in the forest.
Matheran hill station is spread over 214 square kilo metres (21400 Hectare) and is located at 80 km from Mumbai. Scientists was conducted study between 2011 and 2019. This is the first study in 125 years in the forest.
Key Results of the Study
Scientists found that seasonal variation in butterfly diversity was observed. The maximum diversity of butterflies was recorded in winter and the least was observed during monsoon. Scientists also said that the butterfly diversity in the region is stable and the chances of immigration or emigration to the surrounding regions are low.
Prior to the study that was done by Bombay Natural History Society, a British naturalist and researcher JA Betham had surveyed the hills of Matheran for its butterfly diversity in 1894. Betham had reported 78 species of butterflies then.
Importance of Butterflies diversity
The Butterfly diversity indicate healthy environment and ecosystems. They indicate wide range of invertebrates. Butterfly diversity is seldom used by the ecologists to study the impact of habitat loss, climate change and habitat fragmentation.
Matheran Hill Station
It is a hill station located in Mumbai, Maharashtra. The rock types in the hills are mainly composed of Deccan Trap.
Deccan Trap is a large igneous province in west-central India. The term trap has been used for the type of rock formations that are found in this region. They have multiple layers of flood basalt.
The Deccan Trap was formed 66.25 million years ago in the end of Cretaceous period. Cretaceous period lasted between 145 million years ago and 66 million years ago. It is the final period of Mesozoic Era (Geologic time period) It is also known as the Age of Reptiles and the Age of Conifers.
