why western ghats have a greater amphibian species diversity than the eastern ghats?

Western Ghats rise majestically to over 2500 meters above mean sea level to capture the moisture laden trade winds that blow annually once over the India sub-continent.Thus rainfall is high and the Western ghats is a continuous land area. This proves greater amphibian population in Western ghats than eastern ghats .

Western ghats are continuous mountains from south Kerala to Maharashtra. Its average height is also very high at more than 1000m. But eastern ghats is not that much continuous being split by many major rivers. Its average height is also around 600m.

Usually more biodiversity is found in tropical rainforests which receives very heavy annual rainfall. During southwest monsoon western ghats acts as a barrier for the moisture winds from Arabian sea causing very heavy rainfall. Hence western ghats is full of rainforests.
But eastern ghats is parallel to the north east monsoon winds. So rainfall is low compared to western ghats.

Southwest monsoon rainfall acts as source for many major rivers which makes it very fertile forming rainforests. These rainforests in western ghats acts as a home for more flora and fauna. This is the reason for more biodiversity in western ghats
