The districts in the interior are thickly covered by tropical moist deciduous and tropical dry deciduous forests.

Some of the trees which grow in abundance in Odisha are

Flora

Almost one-third of Odisha is covered by forests which make up about 37.34% of the total land area of the state. These forests cover most of southern and western Odisha. The eastern plains adjacent to the coast are covered by farmlands. The forest cover of Odisha extends over an area of 58,136.869 square kilometres out of which reserve forests make up an area of , demarcated protected forests make up and undemarcated protected forests make up . Other types of forests make up while unclassed forests make up of the total forest cover. Bon Jour The State Government of Odisha also classifies forests based on their density. About of land are classified as very dense forests with a canopy density of over 86 percent, of forests are classified as moderately dense cover with a canopy density of 50 to 70 percent and of land are classified as an open forest with a canopy density of 10 to 40 percent. Odisha is the vast state of plants and animals. Odisha's forests yield large quantities of teak and bamboo. Teak, apart from medicinal plants and Kendu leaves contribute substantially towards Odisha's economy. Odisha's forest ecosystem has been greatly affected by deforestation and illegal smuggling and poaching. The state government has established the Odisha Forest Development Corporation to combat the means of smuggling. The State Pollution Control Board has brought a set of rules to force in order to combat environmental pollution.


Chilika Lake

In 1981, Chilika Lake was designated the first Indian wetland of international importance under the

. Over a million migratory waterfowl and shorebirds winter here including many rare and endangered species. The lake is of great value in preserving genetic diversity and over 400 vertebrate species have been recorded. However conflicts have arisen over the ecosystem of the lake such as Siltation, and disagreements between fisherman, resulting in an overall
loss of biodiversity Biodiversity loss includes the worldwide extinction of different species, as well as the local reduction or loss of species in a certain habitat, resulting in a loss of biological diversity. The latter phenomenon can be temporary or permanent, de ...
. As a result, the Odisha State Government with support from the Government of India adopt adaptive conservation and management actions. In 1992, the Government of Odisha, concerned by the degradation of the lake's ecosystem, established the Chilika Development Authority (CDA) for the restoration and overall development of the lake under the

A strong support network was created with 7 state government organisations, 33 NGOs, 3 National Government Ministries, 6 other organisations, 11 International organisations, 13 research institutions and 55 different categories of community groups established good international contacts for protection in the area. In November 2002, the Ramsar Wetland Conservation Award was presented to the Chilika Development Authority for "outstanding achievements in the field of restoration and wise use of wetlands and effective participation of local communities in these activities". The ecological richness of the lake is of great value in preserving the genetic diversity because of the multiplicity of its habitat, flora and fauna. (Some are pictured in the photo gallery). The

Flora

Recent surveys revealed an overall 726 species of flowering plants belonging to 496 genera and 120 families. This represents about one–fourth of the vascular plant species of the Odisha state where some 2900 species altogether are found. Fabaceae is the most dominant plant family followed by Poaceae and Cyperaceae. Certain species were found to be characteristic of specific islands. Important species identified are:. * Leguminosae, Poaceae, and Cyperaceae * Endemic cassipourea ceylanica * Five species of

(land lordship) system in 1953, traditional fishing areas continued to be leased out to cooperatives of local fishermen. Fishing, particularly, prawn fishing, became increasingly remunerative with outside interest playing an important role. But in 1991, when the government of Odisha proposed a leasing policy that would have resulted in the auction of leases to the highest bidder, fishermen's cooperatives challenged the order in court. The High Court of Odisha ordered the Government to enact changes that would protect the interests of traditional fishermen and since then no new leases have been reported. This has resulted in a chaotic regime in which powerful vested interests from outside dominate, and the local people have been subordinated. Butter catfish and ''

of Chilika lake. Chilka is home to the only known population of Irrawaddy dolphins in India and one of only two lagoons in the world that are home to this species. It is classified as Critically Endangered, in five of the six other places it is known to live. A small population of bottlenose dolphins, also migrate into the lagoon from the sea. Chilika fishermen say that when Irrawaddy dolphins and bottlenose dolphins meet in the outer channel, the former get frightened and are forced to return toward the lake. Some Irrawaddy dolphins used to be sighted only along the inlet channel and in a limited portion of the central sector of the lake. After the opening of the new mouth at Satapada in 2000, they are now well distributed in the central and the southern sector of the lake. The number of dolphins sighted has varied from 50 to 170. A 2006 census counted 131 dolphins and the 2007 census revealed 138 dolphins. Out of the 138 dolphins, 115 were adults, 17 adolescents and six calves. 60 adults were spotted in the outer channel followed by 32 in the central sector and 23 in the southern sector. Dolphin tourism provides an important alternative source of income for many local residents. There are four tourist associations in Satapada employing three hundred and sixty 9-HP long-tail motor boats taking tourists to a area of the lake for dolphin watching. About 500 fishing families are involved in this business. The Odisha Tourism Department and the Dolphin Motorboat Association, an NGO at Satpada, report about 40,000 tourists visit Chilika every year for dolphin Watching. October–January and May–June are the peak season for tourists at Chilika, with a maximum 600–700 per day during December–January. The Dolphin Motorboat Association has 75 8-passenger motorboats for dolphin watching. Tourists pay Rs. 250 for 60–90 minutes per trip. According to the Association, most tourists see dolphins. Only 5% return disappointed. Besides the Association, the Odisha Tourism Department organises "dolphin-watch" for tourists. Even during monsoon, about 100 tourists/day visit the lake. Boat based dolphin watching tours impact dolphin behavior and cause several accidental dolphin deaths each year. CDA conducts an annual census of dolphin deaths. They report 15 deaths in 2003–04, 11 in 2004–05, 8 in 2005–06 and 5 in 2006–07. 40% of the 2006–07 deaths were by mechanised boats. Since 1984, the

has been conducting a science-based community education project to conserve the Irrawaddy dolphins and Chilika Lake. They have determined the primary cause of mortality for this population of dolphins is floating gill nets and hook line fisheries and the secondary cause is boat strikes from increasing unmanaged tourism activities. The Irrawaddy dolphins have a seemingly mutualistic relationship of co-operative fishing with the traditional fishermen. Fishermen recall when they would call out to the dolphins, to drive fish into their nets. Castnet fishing with the help of Irrawaddy dolphins in upper reaches of the Ayeyawady River has been well documented. The only other sub-populations of Irrawaddy dolphins are found in a stretch of the
