Lecture 1-2

FLORA AND FAUNA.

Ecological damage has left much of the country devoid of animal life. Bird species include a variety of warblers, eagles, owls, buzzards, heron, ducks, and larks. Mammals include wolves, elk, hedgehogs, squirrels, and weasels. Leopards and wildcats can be found in some forested areas. As of 2002, there were at least 97 species of mammals, 203 species of birds, and over 4,800 species of plants throughout the country.



ENVIRONMENT.

Uzbekistan's main environmental problems are soil salinity, land pollution, and water pollution. In 1992, Uzbekistan had the world's 27th highest level of carbon dioxide emissions, which totaled 123.5 million metric tons, a per capita level of 5.75 metric tons. In 2000, the total of carbon dioxide emissions was at 118.6 million metric tons. Chemicals used in farming, such as DDT, contribute to the pollution of the soil. Desertification is a continuing concern.

The nation's forestlands have also been threatened. Between 1990–1995, deforestation occurred at an annual average rate of 2.65%. However, reforestation efforts have begun as of the late 1990s.

The country's water supply also suffers from toxic chemical pollutants from industrial activity as well as fertilizers and pesticides. Uzbekistan has 16 cu km of renewable water resources, with 94% of annual withdrawals used for farming and 2% used for industrial purposes. The nation's cities produce an average of 45.8 million tons of solid waste per year.

The draining and evaporation of the Aral Sea has been considered one of the worst ecological disasters in the world. Irrigation withdrawals from the Amu Darya and Syr Darya rivers have been a major cause of lake shrinkage. As a result, pesticides and natural salts in its water have become increasingly concentrated so that plant and wildlife habitats have been destroyed. As of 2002, the area of the Aral Sa was reported to cover less than half the size of the original basin.

As of 2003, only 2% of Uzbekistan's total land area is protected. According to a 2006 report issued by the International Union for Conservation of Nature and Natural Resources (IUCN), threatened species included 7 types of mammals, 16 species of birds, 2 types of reptiles, 4 species of fish, 1 species of invertebrate, and 1 species of plant. Threatened or rare species include the markhor, Central Asia cobra, Aral salmon, slender-billed curlew, and Asiatic wild dog. The Jeseter hladky has become extinct.
