The source is in the Mercantour National park near the border with Italy. The river flows through the town of Saint-Martin-Vésubie which is a major center for hiking. It flows into the Var near Levens. One of its tributaries is the Gordolasque.

paragraph_text: It begins at an elevation of on Monte Chiappo and runs a course of before flowing into the Scrivia as its major right tributary at Vignole Borbera.

paragraph_text: The heartland of this genus is Africa, but several species occur in tropical southern Asia. As a group, this genus is highly successful; many species are abundant in a range of habitats in the tropics, and two now have a much more extensive distribution.

paragraph_text: 02 Manas Wildlife Sanctuary, Assam Assam, India 015 20th century 0338! 338; 1985; vii, ix, x Manas Wildlife Sanctuary, located in the northeastern state of Assam covers an area of 50,000 hectares (120,000 acres) in the plains of the Manas River in the foot hills of the Himalayas, on the border with Bhutan (contiguous with the Manas Wildlife Sanctuary in Bhutan). It was inscribed as a World Heritage Site by UNESCO in 1985 for its unique natural environment. The sanctuary is the habitat of several species of plants, 21 most - threatened species of mammals (out of 55 mammal species in the sanctuary), 36 reptile species, 3 amphibians and 350 species of birds. Endangered species include tiger, pygmy hog, clouded leopard, sloth bear, Indian rhinoceros, wild buffaloes (the only pure strain of buffalo in India), Indian elephants, golden langur and Bengal florican. In 1907, it was declared a reserve forest, was declared a sanctuary in 1928, and became a tiger reserve in 1973 as part of ``Project Tiger ''and a World Heritage Site in December 1985. Plants listed under the broad category of Burma Monsoon Forests include 285 species of Dicotyledons and 98 species of Monocotyledons. Since 1992, the sanctuary was listed under`` The World Heritage in Danger'', but removed in 2011 after significant conservation efforts.

paragraph_text: The Rockefeller Wildlife Refuge is a large area of marshland in Cameron Parish, Louisiana, United States. It was donated to the state with certain provisions as to its management as a wildlife sanctuary. It is a biodiverse habitat and is visited annually by many migratory birds. Much research is undertaken into marshland management and alligator ranching, and the income from the sale of alligators contributes to conservation of the marshland.

paragraph_text: The Wildlife of Costa Rica comprises all naturally occurring animals, fungi and plants that reside in this Central American country. Costa Rica supports an enormous variety of wildlife, due in large part to its geographic position between the North and South American continents, its neotropical climate, and its wide variety of habitats. Costa Rica is home to more than 500,000 species, which represents nearly 4% of the total species estimated worldwide, making Costa Rica one of the 20 countries with the highest biodiversity in the world. Of these 500,000 species, a little more than 300,000 are insects.

paragraph_text: For many years Sugar island was held in private ownership with plans to build a bridge and residential housing on the island. There were objections to this plan, mainly by environmental groups, as the island is a resting point for many species of migratory birds. The island was recently purchased by the US Fish and Wildlife service for $434,100 and will be made into a wildlife refuge.

paragraph_text: Growing scientific recognition of the role of private lands for endangered species recovery and the landmark 1981 court decision in Palila v. Hawaii Department of Land and Natural Resources both contributed to making Habitat Conservation Plans/ Incidental Take Permits "a major force for wildlife conservation and a major headache to the development community", wrote Robert D.Thornton in the 1991 Environmental Law article, Searching for Consensus and Predictability: Habitat Conservation Planning under the Endangered Species Act of 1973.

paragraph_text: At least 74 species of Iranian wildlife are on the red list of the International Union for the Conservation of Nature, a sign of serious threats against the country’s biodiversity. The Iranian Parliament has been showing disregard for wildlife by passing laws and regulations such as the act that lets the Ministry of Industries and Mines exploit mines without the involvement of the Department of Environment, and by approving large national development projects without demanding comprehensive study of their impact on wildlife habitats.

paragraph_text: Kiunga is a division in the Lamu District of Coast Province located close to the Indian Ocean coast of northern Kenya, and only 15 kilometres to the border with Somalia. A major marine conservation area, the Kiunga Marine National Reserve has its headquarters at Kiunga. The reserve is an important habitat for mangrove, turtles, and many species of birds. Total population of the division is 3310 (1999 census ).

paragraph_text: One species in particular received widespread attention—the whooping crane. The species' historical range extended from central Canada South to Mexico, and from Utah to the Atlantic coast. Unregulated hunting and habitat loss contributed to a steady decline in the whooping crane population until, by 1890, it had disappeared from its primary breeding range in the north central United States. It would be another eight years before the first national law regulating wildlife commerce was signed, and another two years before the first version of the endangered species act was passed. The whooping crane population by 1941 was estimated at about only 16 birds still in the wild.

paragraph_text: Major European rivers flow from Switzerland, such as the Rhine, the Rhone, the Inn, the Ticino and the Po, all of which have headwaters in the Alps and flow into neighbouring countries, finally emptying into the North Sea, the Mediterranean Sea, the Adriatic Sea and the Black Sea. Other rivers such as the Danube have major tributaries flowing into them that originate in the Alps. The Rhone is second to the Nile as a freshwater source to the Mediterranean Sea; the river begins as glacial meltwater, flows into Lake Geneva, and from there to France where one of its uses is to cool nuclear power plants. The Rhine originates in a 30 square kilometre area in Switzerland and represents almost 60 percent of water exported from the country. Tributary valleys, some of which are complicated, channel water to the main valleys which can experience flooding during the snow melt season when rapid runoff causes debris torrents and swollen rivers.

paragraph_text: Each year, nearly $200 million in hunters' federal excise taxes are distributed to state agencies to support wildlife management programs, the purchase of lands open to hunters, and hunter education and safety classes. Since 1934, the sale of Federal Duck Stamps, a required purchase for migratory waterfowl hunters over sixteen years old, has raised over $700 million to help purchase more than 5,200,000 acres (8,100 sq mi; 21,000 km2) of habitat for the National Wildlife Refuge System lands that support waterfowl and many other wildlife species and are often open to hunting. States also collect money from hunting licenses to assist with management of game animals, as designated by law. A key task of federal and state park rangers and game wardens is to enforce laws and regulations related to hunting, including species protection, hunting seasons, and hunting bans.

paragraph_text: The Danube was once a long - standing frontier of the Roman Empire, and today flows through 10 countries, more than any other river in the world. Originating in Germany, the Danube flows southeast for 2,850 km (1,770 mi), passing through or touching the border of Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova and Ukraine before draining into the Black Sea. Its drainage basin extends into nine more countries. The Danube river basin is home to fish species such as pike, zander, huchen, wels catfish, burbot and tench. It is also home to a large diversity of carp and sturgeon, as well as salmon and trout. A few species of euryhaline fish, such as European seabass, mullet, and eel, inhabit the Danube delta and the lower portion of the river.

paragraph_text: On 16 March 1934, President Franklin D. Roosevelt signed the Migratory Bird Hunting Stamp Act, which requires an annual stamp purchase by all hunters over the age of sixteen. The stamps are created on behalf of the program by the US Postal Service and depict wildlife artwork chosen through an annual contest. They play an important role in habitat conservation because ninety-eight percent of all funds generated by their sale go directly toward the purchase or lease of wetland habitat for protection in the National Wildlife Refuge System.[citation needed] In addition to waterfowl, it is estimated that one third of the nation's endangered species seek food and shelter in areas protected using Duck Stamp funds.[citation needed]

paragraph_text: Sunbirds are a tropical Old World family, with representatives in Africa, Asia and Australasia. In Africa they are found mostly in sub-Saharan Africa and Madagascar but are also distributed in Egypt. In Asia the group occurs along the coasts of the Red Sea as far north as Israel, with a gap in their distribution till Iran, from where the group occurs continuously as far as southern China and Indonesia. In Australasia the family occurs in New Guinea, north eastern Australia and the Solomon Islands.  They are generally not found on oceanic islands, with the exception of the Seychelles. The greatest variety of species is found in Africa, where the group probably arose. Most species are sedentary or short-distance seasonal migrants. Sunbirds occur over the entire family's range, whereas the spiderhunters are restricted to Asia.The sunbirds and spiderhunters occupy a wide range of habitats, with a majority of species being found in primary rainforest, but other habitats used by the family including disturbed secondary forest, open woodland, open scrub and savannah, coastal scrub and alpine forest. Some species have readily adapted to human modified landscapes such as plantations, gardens and agricultural land. Many species are able to occupy a wide range of habitats from sea level to 4900 m.

paragraph_text: In 1972, he received a Ph.D. in Marine Biology. He documented the wildlife of the region on land, photographing many of the wild flowers of Israel, with a special attention to the documentation of the Plants of the Bible. Underwater he photographed many hundreds of fish species as well as marine invertebrates from the Red Sea and the Mediterranean Sea. "Upeneus davidaromi", a species of goatfish found in the Red Sea, was named in his honour in 2001.

paragraph_text: The U.S. ecology is megadiverse: about 17,000 species of vascular plants occur in the contiguous United States and Alaska, and over 1,800 species of flowering plants are found in Hawaii, few of which occur on the mainland. The United States is home to 428 mammal species, 784 bird species, 311 reptile species, and 295 amphibian species. About 91,000 insect species have been described. The bald eagle is both the national bird and national animal of the United States, and is an enduring symbol of the country itself.There are 59 national parks and hundreds of other federally managed parks, forests, and wilderness areas. Altogether, the government owns about 28% of the country's land area. Most of this is protected, though some is leased for oil and gas drilling, mining, logging, or cattle ranching; about .86% is used for military purposes.Environmental issues have been on the national agenda since 1970. Environmental controversies include debates on oil and nuclear energy, dealing with air and water pollution, the economic costs of protecting wildlife, logging and deforestation, and international responses to global warming. Many federal and state agencies are involved. The most prominent is the Environmental Protection Agency (EPA), created by presidential order in 1970. The idea of wilderness has shaped the management of public lands since 1964, with the Wilderness Act. The Endangered Species Act of 1973 is intended to protect threatened and endangered species and their habitats, which are monitored by the United States Fish and Wildlife Service.
