full_context: Document 1: Valley of Flowers National Park: Valley of Flowers National Park is an Indian national park, located in West Himalaya, in the state of Uttarakhand and is known for its meadows of endemic alpine flowers and the variety of flora. This richly diverse area is also home to rare and endangered animals, including the Asiatic black bear, snow leopard, musk deer, brown bear, red fox, and blue sheep. Birds found in the park include Himalayan monal pheasant and other high altitude birds. At 3352 to 3658 meters above sea level, the gentle landscape of the Valley of Flowers National Park complements the rugged mountain wilderness of Nanda Devi National Park to the east. Together, they encompass a unique transition zone between the mountain ranges of the Zanskar and Great Himalaya. The park stretches over an expanse of 87.50 km and it is about 8 km long and 2 km wide. Both parks are encompassed in the Nanda Devi Biosphere Reserve (223,674 ha) which is further surrounded by a buffer zone (5,148.57 km). This Reserve is in the UNESCO World Network of Biosphere Reserves since 2004.

It is a tourist destination and conservation area particularly notable as a refuge for the endangered Indian one-horned rhinoceros ("Rhinoceros unicornis"), hosting the largest population of wild Indian one-horned Rhinoceros in the world. The park contains significant stock of three other large herbivores — the Asian Elephant, the Asiatic Water Buffalo and the eastern subspecies of the Swamp Deer. Kaziranga also has the highest density of tiger in the world and is declared a Tiger Reserve in 2006. Kaziranga is recognized as an Important Bird Area by Birdlife International for conservation of avifaunal species.
Document 3: Bengal tiger: The Bengal tiger ("Panthera tigris tigris") is the most numerous of the tiger subspecies. By 2011, the total population was estimated at fewer than 2,500 individuals with a decreasing trend. None of the Tiger Conservation Landscapes within the Bengal tiger's range is considered large enough to support an effective population size of 250 adult individuals. Since 2010, it is listed as Endangered on the IUCN Red List. An example of charismatic megafauna, the Bengal tiger is the most familiar tiger subspecies, as well as the second largest
Document 4: Sumatran tiger: The Sumatran tiger ("Panthera tigris sumatrae") is a tiger subspecies that lives in the Indonesian island of Sumatra. It was listed as Critically Endangered on the IUCN Red List in 2008, as the population was estimated at 441 to 679 individuals, with no subpopulation larger than 50 individuals and a declining trend.
Document 5: Botcha Nature Reserve: Botcha Nature Reserve (Russian: Ботчинский заповедник ) (also Botchinsky) is a Russian 'zapovednik' (strict ecological reserve). It is the northernmost reserve inhabited by the endangered Amur Tiger. The reserve is located in the north-eastern part of the Sikhote-Alin mountain range; it includes the Botchi River basin on its eastern slopes. The reserve is about 120 km south of the port city of Sovetskaya Gavan in the Sovetsko-Gavansky District of Khabarovsk Krai. The reserve was created in 1994, and covers an area of 267380 ha .
Document 6: Salamanperä Strict Nature Reserve: Salamanperä Strict Nature Reserve ("Salamanperän luonnonpuisto") is home to Wolverine and Finnish Forest Reindeer ("R. tarandus fennicus"), and it is said that wolves can be heard while in the nature reserve. It has a trail, but the distance of the trail is unknown as of now. This nature reserve is connected to Salamajärvi National Park and is a strict nature reserve. It is located in the Central Finland region of Finland.
Document 7: Siberian Tiger Introduction Project: The Siberian Tiger Introduction Project involves reestablishing populations of the Siberian tiger ("Panthera tigris altaica)", also known as the Amur tiger, in their former range and also expanding their range by introducing them as replacements of their genetically similar relative, the extinct Caspian tiger ("Panthera tigris virgata") which inhabited Central and Western Asia. Currently, the Siberian tiger inhabits the cold mountains of the Russian Far East and northern China.
Document 8: Lazovsky Nature Reserve: Lazovski Nature Reserve (Russian: Лазовский заповедник ) (also Lazovsky) is a Russian 'zapovednik' (strict ecological reserve) that sits on the southeastern slopes of the Sikhote-Alin mountain range, down to the coast of the Sea of Japan, in Primorsky Krai in the Russian Far East about 150 km due east of Vladivostok. The reserve is 95% forested, with the largest stand of yew trees in the Russian Far East, and has been the subject of scientific study since the 1800s for its rich communities of plants and animals found in the transition mountain to maritime zones in a temperate, rainy forest. Lazonvsky Reserve contains more species than any other reserve in the Russian Far East, and 60% of the species in the Priomorky region are found on the reserve. It is jointly managed with the Zov Tigra National Park, located about 50 km to the northwest. The reserve is situated entirely within the Lazovsky District of Primorsky Krai. The reserve was created in 1957, and covers an area of 120989 ha .
Document 9: Protected areas of Vietnam: Many areas of Vietnam are under protection. While the national reserves cover small areas of scientific significance with restricted access, the national parks also cover wetlands of Ramsar designated areas and BirdLife International inscribed bird areas. The largest of the national parks initially covered were the Cúc Phương National Park, the Cát Tiên National Park, and the Côn Đảo National Park which to start with were forest areas cum reserves or prohibited areas. The objective for creating national parks was to allow access to the reserved areas as a part of ecotourism and cultural needs with full attention to the basic approach of conservation of natural environmental resources.
Document 10: South China tiger: The South China tiger ("Panthera tigris amoyensis") is a tiger subspecies in the provinces of Fujian, Guangdong, Hunan, Jiangxi in southern China. It has been listed as Critically Endangered on the IUCN Red List since 1996, and is possibly extinct in the wild since no wild individual has been recorded since the early 1970s. Already in the late 1990s, continued survival was considered unlikely due to low prey density, widespread habitat degradation and fragmentation, and other human pressures. The name "Amoy tiger" was used in the fur trade. It is also known as the "South Chinese", the "Chinese", and the "Xiamen" tiger.
Document 11: Temperate rainforests of the Russian Far East: The temperate rainforests of the Russian Far East are found within the Russian states of Primorsky Krai and Khabarovski Krai and contains the Sikhote-Alin mountain range. Found within the Russian Federation, this area is one of the most productive and diverse forests in the world and also contains one of the highest endangered species densities on Earth. While most temperate rainforests around the world have retained only a fraction of their historical range, these forests maintain the majority of their former range and almost all of their historical biodiversity. The region is also notable for having what has become the last remaining large tract of viable habitat for the critically endangered Amur tiger and Amur leopard.
Document 12: Udegeyskaya Legenda National Park: Udegeyskaya Legenda National Park (Russian: Удэгейская легенда ) (also, Udege Legend) covers the richest coniferous-deciduous forest on the western slope of the Central Sikhote-Alin mountains of the Russian Far East. The Sikhote-Alin is a range that runs north-south through Primorsky Krai (in English, "Maritime Region"). The park is designed to protect west-slope river valley habitat, and to support the remnant of the indigenous Udege people. The area is known for abundant fishing and boating on the streams and rivers. It is also a refuge for the endangered Amur tiger. The park is roughly midway between the city of Vladivostok (520 km to the southwest), and Khabarovsk (440 km to the northwest). The relatively warm waters of the Sea of Japan are to the east, the Korean peninsula to the south, and China to the West.
Document 13: Siberian tiger: The Siberian tiger ("Panthera tigris altaica"), also called Amur tiger, is a tiger subspecies inhabiting mainly the Sikhote Alin mountain region with a small population in southwest Primorye Province in the Russian Far East. The Siberian tiger once ranged throughout all of Korea, north-eastern China, Russian Far East, and eastern Mongolia. In 2005, there were 331–393 adult and subadult Siberian tigers in this region, with a breeding adult population of about 250 individuals. The population had been stable for more than a decade due to intensive conservation efforts, but partial surveys conducted after 2005 indicate that the Russian tiger population was declining. An initial census held in 2015 indicated that the Siberian tiger population had increased to 480–540 individuals in the Russian Far East, including 100 cubs. This was followed up by a more detailed census which revealed there was a total population of 562 wild Siberian tigers in Russia.
Document 14: Indochinese tiger: The Indochinese tiger ("Panthera tigris corbetti") (Thai: เสือ โคร่ง อิน โด จีน , "S̄eụ̄x khor̀ng xin do cīn") (Vietnamese: "Hổ Đông Dương" ) is a tiger subspecies that lives in Myanmar, Thailand, Lao PDR, Viet Nam, Cambodia, and southwestern China. It has been listed as Endangered on the IUCN Red List since 2008, as the population seriously declined and approaches the threshold for Critically Endangered. As per 2011, the population was thought to comprise 342 individuals. The largest population unit survives in Thailand estimated at 189 to 252 individuals. There are 85 individuals in Myanmar, and only 20 Indochinese tigers remain in Viet Nam. It is considered extinct in Cambodia.
Document 15: Zov Tigra National Park: Zov Tigra National Park (Russian: Зов Тигра национальный парк)), (in English, "Call of the Tiger National Park", or "Roar of the Tiger") is a mountainous refuge for the endangered Amur Tiger. The park encompasses an area of 83384 ha on the southeast coast of Russia's Far East in the federal district Primorsky Krai (in English, "Maritime Region"). The park is about 100 km northeast of Vladivostok, on both the eastern and western slopes of the southern Sikhote-Alin mountain range, a range that runs north-south through the Primorsky Krai. The relatively warm waters of the Sea of Japan are to the east, the Korean peninsula to the south, and China to the West. The terrain in rugged and difficult to access, with heavily forested taiga coexisting with tropical species of animals and birds. The park is relatively isolated from human development, and functions as a conservation reserve.
