Krishna Wildlife Sanctuary
Krishna Wildlife Sanctuary is a wildlife sanctuary and estuary located in Andhra Pradesh, India. It is one of the rarest eco-regions of the world because it harbors vast tracts of pristine mangrove forests. It is believed by conservationists to be one of the last remaining tracts of thick primary mangrove forests of South India, which is rapidly disappearing due to absence of protective measures.
Geography
The sanctuary is a part of the mangrove wetland in Andhra Pradesh and are located in the coastal plain of Krishna delta.The Krishna mangroves lie between 15° 2' N and 15° 55' N in latitude and 80° 42'- 81° 01' E in longitude spread across Krishna and Guntur districts of Andhra Pradesh.
It includes Sorlagondi Reserve Forest, Nachugunta Reserve Forest, Yelichetladibba Reserve Forest, Kottapalem Reserve Forest, Molagunta Reserve Forest, Adavuladivi Reserve Forest and Lankivanidibba Reserve Forest. They occupy the islands of the delta and the adjacent mainlands of Krishna and Guntur Districts.
A part of the mangroves is located far from the main mangrove area. This unconnected regions lies near Machilipatnam on its eastern side and Nakshatranagar on its western side.
Flora and fauna
The estuary of Krishna River passes through the sanctuary, and the mangroves line the estuary. It is believed that this region potentially holds one of the most significant populations of fishing cats in the world and yet, no concrete surveys on fishing cats or community-based fishing cat conservation efforts have been carried out here. The area has the potential to become world's first reserve for a few of the IUCN identified endangered species including the fishing cat or better known locally as bavuru pilli.Some of the tree species found in the sanctuary are:
Casuarina equisetifolia, Pongamia gladra, Calotropis gigantea, Cassia auriculata, Thespesia populnea, Ipomaea biloba, Spinifex squarrosus, Spinifex littoreus, Pongamia pinnate, Prosopis juliflora, banyan, peepul, margosa, tumma, mango, palmyra.
