Talsari is situated between 21°35’48” northern latitude and 87°27’17” eastern longitude, in north eastern coast of Odisha state, and has area spread in Bhogarai&Baliapal blocks of Balasore district. Subarnarekha and estuarine rivers meanders through Talsari landscape before and it is also crisscrossed with perennial because of its proximity to the sea.

The landscape has two distinct geographical regions – the coastal belt and the inner alluvial plains. The coastal belt, shaped like a strip  is about 81 km wide, and has sand dunes along the coast with some ridges. The sand dune are under threat due to the destruction of the vegetation either due to due to the development and other anthropogenic activities along the coastal areas. TThe area mostly get flooded by brackish water of estuarine rivers, which is unsuitable for cultivation, whereas the alluvial plain have a wide stretch of highly fertile and irrigated land. The weather is generally hot with high humidity. May is considered the hottest and December as the coolest month of the year.

It is rich in both terrestrial and marine wildlife. Many species of mammals, birds, reptiles, amphibians with species of insects and microfauna are found in Talsari. It is also home to large number of red ghost crabs (Ocypodemacrocera) that are considered as glory of this beach/region. Crabs habitats are mostly near estuaries and beaches, that are not frequented by humans. The deep burrows dug by these crabs play a crucial role in keeping the local ecology thriving. Research suggests that the crab’s digging behaviour enhances oxygenation in the ground soil and facilitates decomposition of organic materials and nutrient recycling.

But, the environmental pollution, human exploitation and pollutants originating from human activity, habitat destruction and rising unsustainable tourism in recent years, have impacted the natural habitat of these crabs as well as have resulted in the decline of the population of red ghost crabs.
