Humid Season Al: The climate is humid season al and seasonal, with hot summers and cold winters. There is a frost-free growing season of 90 to 200 days or more and a cold winter or dormant season. The precipitation is 30 to 60 inches annually, distributed through the year with some snow.In the United States this forest has the greatest number of the nearly 800 native tree species, more than 100 being commercially important for hardwood lumber. The northern hardwoods of the Northeastern states west to the Great Lakes are designated as beech-maple-hemlock forest from the commonest large trees.
Savanna grass-ind develops in regions of high temperature that ave a distinct wet and dry season. Growth is ipid in the wet season, but the plants become ry and low in quality in the dry season. Widely >aced drought-resistant trees may occur in some
•eas such as in the savanna parklands of Africa id Australia. Savannas are subject to flooding i the wet season and to extensive burning in le dry season. These grasslands are heavily•azed by large numbers of cattle. Major prob-ms are poor grass quality in the dry season, irasites, and disease. The tsetse fly is a major•oblem in Africa. There are no true savannas North America.
The third ecological zone is the coastal region comprising a narrow strip of rich alluvium that runs parallel to the Atlantic seaboard and extends inland to a maximum depth of no more than 40 miles (65 km). This coastal ribbon, which contains 72 of the total land area and 90? of the population, is Guyana's commercial and agricultural region. Within it is situated Georgetown, the capital and principal port, as well as New Amsterdam and several smaller ports, most of Guyana's rural villages, and all of its sugar plantations. The climate along the coast is humid season al, with the temperature averaging 80° F (27° C). A rainy season extends from April to August.
