Transcript of Nepal's ecosystem

Task The major ecosystems in Nepal consist of Grassland, and forests, here is a little about each of them.
Grasslands-there is a narrow lowland at the base of the Himalayas, about 25 km wide. Nepal's largest patch of continuous grassland is the Sukla Phanta Wildlife Reserve.

Forests-The native forests of the mountain region change from East to West as precipitation decreases. Subtropical forests dominate the lower elevations of the Hill region. They form a mosaic running East and West across Nepal, with Himalayan subtropical broad leaf forests between 500 and 1,000 meters. Himalayan subtropical pine forests between 1,000 and 2,000 meters. At higher elevations, to 3,000 meters are found temperate broad leaf forests to the East of the Gandaki River and Western Himalayan broad leaf forests to the West.
25% of Nepal's land area is covered with forest. Flora and Fauna of Nepal Nepal Flora
(about 7,000 species) Milkworts, 7 species
Free ferns
Cycades
Orchids, over 300 species
May Apple
The cooler, drier climate and higher altitude of the Hills region suits a different variety of Fauna and Flora. Pines and oak tree prevail here. Alders, Durals, Walnuts, Chestnuts, Maples, Wild Cherries, Firs, Birches, Rhodendrons and Larches. In forests live Black Bears, Wild Boar, Wildcats, Foxes, and a wide variety of Birds. In lower mountains- foxes, various wild goats, and sheep, snow leopards, musk deer, and yaks. The most important animal is the yak a relative of cattle and buffalo. Medicinal Plants Bikh, found in the sub alpine and alpine zones
Bojo, found in the temperate zone
Paunch Aunle, found in the sub alpine and alpine areas
Somlata, in the sub alpine and alpine zones
Pip la, in the tropical and subtropical zones Nepal's Fauna Approximately 180 types of mammals, 270 breeding bird species, 120 kinds of reptiles, and 50 amphibian species live their.
Elephants, Rhinoceros, Leopards, Tigers, Deer, and crocodiles live in the forests and swamps. Threats Although the population density has been low, it is now growing, especially in the Southern Terai belt, and much of the region has been converted to farmland since the forest was cut down for timber.
Their are many endangered species such as the one-horned Rhinoceros,the wild water buffalo, swamp deer, pygmy hog, wild elephant, Hispid hare, wild yak, snow leopard, Red panda, and the Gharial Crocodile.
Also tigers, and leopards are the top most endangered. They are killed for their superb coats and bones. Bones are used in Chinese and Japanese traditional medicine.
Musk Deer are hunted for musk, a powdery substance , which the male deer secretes from a gland in the Abdomen. It's a highly valued item for perfumes and medicine.
Himalayan Black Bear are endangered for their Gall Bladder which provides ingredients of one of the most coveted oriental medicines.
Water Pollution is the most serious environmental quality issue in Nepal. It is caused by the disposal of solid and liquid wastes on land and surface water. The most significant waste is sewage, industrial effluent agriculture chemicals and residues. Their is no treatment plant in any industrial district and industrial effluent is directly discharged into the adjoining rivers or streams. Nepal Colorado Rockies Nepal is home to the largest Mountains in the world. Nepal has many animals on the Mountains such as Black bears, snow leopards, and fox that are also on the Colorado Rockies. They also have in common that the average annual rain fall is approximately 16 inches. Adding on to that, in both places the elevations rises, and gets colder, and has more rain as the elevation decreases.
Finally, the elevations in both places drop easily, they have floods, and ruff winds all the time. Colorado is home to the Colorado Rockies which are very tall mountains in the U.S. They have animals on the mountains that include Fox, Black bears, and Snow leopards, just like Nepal. Also they have in common that in the Himalayas the average annual rain fall is 16 inches, just like in the Colorado Rockies. Further more, as the elevation increases it gets cooler, and gets wetter as elevation drops. Finally, the elevations drops frequently, they have many floods, and high winds on both mountains.
