The Sri Lankan Civil war was very costly, killing over 100,000+ civilians and 50,000+ fighters from both sides of the conflict.
 The "Tamil Centre for Human Rights" recorded that from 1983 to 2004, 47,556 Tamil civilians were murdered by both the Sri Lankan government and IPKF forces.
 Another organization called NESOHR published that from the beginning of the war to the , 4000 to 5000 Tamil civilians were killed in large scale massacres, with a total civilian death of around 40,000.
 Civilian casualties that occurred on 2009 is of major controversy, as there were no organizations to record the events during the final months of the war.
 The Sri Lankan government revealed that 9,000 people were killed in the final months of the war, but it did not differentiate between LTTE cadres and civilians.
 The UN, based on credible witness evidence from aid agencies and civilians evacuated from the "Safe Zone" by sea, estimated that 6,500 civilians were killed and another 14,000 injured between mid-January 2009, when the "Safe Zone" was first declared, and mid-April 2009.
 There are no official casualty figures after this period but estimates of the death toll for the final four months of the civil war (mid-January to mid-May) range from 15,000 to 20,000.
 A US State Department report has suggested that the actual casualty figures were probably much higher than the UN's estimates and that significant numbers of casualties weren't recorded.
 A former UN official has claimed that up to 40,000 civilians may have been killed in the final stages of the civil war.
 Several human rights groups have even claimed that the death toll in the last months of the war could be 70,000.
 The Sri Lankan government has denied all claims of causing mass casualties against Tamils, arguing that it was "taking care not to harm civilians".
 Instead, it has blamed the LTTE for the high casualty numbers, stating that they used the civilians as human shields.
 Both the Sri Lankan government and the LTTE have been accused by the U.N for war crimes during the last phase of the war.

Lunugamvehera National Park in Sri Lanka was declared in 1995, with the intention of protecting the catchment area of the Lunugamvehera reservoir and wildlife of the area.
 The national park is an important habitat for water birds and elephants.
 The catchment area is vital to maintain the water levels of the five tanks in the down stream of Kirindi Oya and wetland characteristics of Bundala National Park.
 This national park also serves as a corridor for elephants to migrate between Yala National Park and Udawalawe National Park.
 The national park is situated 261 km southwest from Colombo.
 After being closed because of the Sri Lankan civil war, the national park is now open to the general public.
Yala National Park is the most visited and second largest national park in Sri Lanka.
 The park consists of five blocks, two of which are now open to the public, and also adjoining parks.
 The blocks have individual names such as, Ruhuna National Park (block 1) and Kumana National Park or 'Yala East' for the adjoining area.
 It is situated in the southeast region of the country, and lies in Southern Province and Uva Province.
 The park covers 979 km2 and is located about 300 km from Colombo.
 Yala was designated as a wildlife sanctuary in 1900, and, along with Wilpattu was one of the first two national parks in Sri Lanka, having been designated in 1938.
 The park is best known for its variety of wild animals.
 It is important for the conservation of Sri Lankan elephants, Sri Lankan leopards and aquatic birds.
The Sri Lankan sloth bear ("Melursus ursinus inornatus") is a subspecies of the sloth bear found mainly in lowland dry forests in the island of Sri Lanka.
 The Sri Lankan sloth bear is omnivorous.
 It feeds on nuts, berries, and roots, as well as carrion and meat.
 One of its main staples is insects, which it removes from rotting stumps and trees with its long, hairless snout.
 It rarely kills animals.
 Yala National Park is a famous place to sight these mammals in Sri Lanka.
Crocidura hikmiya (Sinharaja shrew or Sri Lankan rain forest shrew) is a species of shrew described from the rainforests of Sri Lanka, based on both morphological and molecular data.
 Its closest sister species is the Sri Lankan long-tailed shrew, another Sri Lankan crocidurine shrew restricted to the high-elevation habitats of the Central Highlands.
 "C. hikmiya" has a shorter tail than the Sri Lankan long-tailed shrew; most of the other characteristics that distinguish the two species are osteological in nature .
Sri Lanka's Killing Fields was an investigatory documentary about the final weeks of the Sri Lankan Civil War broadcast by the British TV station Channel 4 on 14 June 2011.
 Described as one of the most graphic documentaries in British TV history, the documentary featured amateur video from the conflict zone filmed by civilians and Sri Lankan soldiers which depicted "horrific war crimes".
 The video filmed by civilians included harrowing scenes during and after intense shelling of civilian targets, including hospitals, by the Sri Lankan military.
 The "trophy video" filmed by Sri Lankan soldiers showed disturbing scenes of blindfolded victims being executed and dead bodies of naked women being dragged onto trucks by soldiers as they made lewd remarks about the victims.
 The documentary also included interviews with civilians who managed to survive the conflict, United Nations staff based in Sri Lanka during the conflict, human rights organisations and an international law expert.
 The documentary was made by ITN Productions and presented by Jon Snow, the main anchor on Channel 4 News.
Wilpattu National Park (Willu-pattu; Land of Lakes) is a park located on the island of Sri Lanka.
 The unique feature of this park is the existence of "Willus" (Natural lakes) - Natural, sand-rimmed water basins or depressions that fill with rainwater.
 Located in the Northwest coast lowland dry zone of Sri Lanka.
 The park is located 30 km west Anuradhapura and located 26 km north of Puttalam (approximately 180 km north of Colombo).
 The park is 1,317 square kilometers (131, 693 hectares) and ranges from 0 to 152 meters above sea level.
 Nearly sixty lakes (Willu) and tanks are found spread throughout Wilpattu.
 Wilpattu is the largest and one of the oldest National Parks in Sri Lanka.
 Wilpattu is among the top national parks world-renowned for its leopard ("Panthera pardus kotiya") population.
 A remote camera survey was conducted in Wilpattu from July to October 2015 by the Wilderness & Wildlife Conservation Trust.
 A sample of forty nine individual leopards were photo-captured in the surveyed area and the core area density was between that of Yala National Park's Block I and Horton Plains National Park.
The Sri Lankan leopard ("Panthera pardus kotiya") is a leopard subspecies native to Sri Lanka that was first described in 1956 by the Sri Lankan zoologist Deraniyagala.
