BIODIVERSITY
Biodiversity
refers to the variety and the variability of genes, species, populations,
and ecosystems. People worldwide recognize that biological resources feed
and clothe us and provide housing, medicines, and spiritual nourishment.
The natural ecosystems of forests, grasslands, pastures and rangelands,
deserts, tundras, rivers, lakes, and seas contain most of the Earth's
biodiversity. Agricultural lands are also of great importance as repositories,
while gene banks, botanical gardens, zoos, and other germplasm repositories
make a small but significant contribution. The current decline in biodiversity
is largely the result of human activity and represents a serious threat
to human development. Therefore, it is important to inventory initial
biodiversity, which provides a baseline against which to measure anthropogenic
effects and evolutionary trends.
The CD-ROM introduces a database on some biodiversity indicators across
the country, which mainly is derived from field observations in the national
parks and reservations. It also provides information on biological and
landscape diversity by natural zones and lists natural protected areas.
