The adversity of soil and climatic conditions proves to low production levels, as well as little biomass accumulation due to slow rates of nutrient release in cold and wet soils, specifically as a result of limited nitrogen and phosphorus (Nadelhoffer et al. 1996) Additionally, there are low temperatures and strong winds in the tundra causing most vegetation to be dominated by woody plants ...
Chaparral in the Santa Ynez Mountains, near Santa Barbara, California. Chaparral (/ ˌ ʃ æ p ə ˈ r æ l, ˌ tʃ æ p-/ SHAP-ə-RAL, CHAP-) [1] is a shrubland plant community found primarily in California, southern Oregon, and northern Baja California.
Classic Version - Regions of the Amazonic Side Sea level, 22 to 24 °C (72 to 75 °F), but the cold Humboldt Current generates fog. Tierra caliente (Hot land) up to 750–1,000 m (2,460–3,280 ft). Tierra templada (Temperate land) up to 1,850–2,000 m (6,070–6,560 ft). The warmest month has an average temperature of below 22 °C (72 °F).
There are three regions and associated types of tundra: Arctic, [2] Alpine, [2] and Antarctic. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline
Ecoregions may be identified by similarities in geology, physiography, vegetation, climate, soils, land use, wildlife distributions, and hydrology. The classification system has four levels, but only Levels I and III are on this list. Level I divides North America into 15 broad ecoregions; of these, 12 lie partly or wholly within the United States.
These maps show a scale, or index of greenness, based on several factors: the number and type of plants, leafiness, and plant health. Where foliage is dense and plants are growing quickly, the index is high, represented in dark green. Regions with sparse vegetation and a low vegetation index are shown in tan.
The vegetation of the area is less diverse and includes oak, hickory, loblolly, and shortleaf pines. The Ozark and Ouachita-Appalachian Forests region is an area mostly consisting of hills and low mountains, with some wild valleys that make up the 518,690 square kilometres (200,270 sq mi) of land.
Barren vegetation describes an area of land where plant growth may be sparse, stunted, and/or contain limited biodiversity. Environmental conditions such as toxic or infertile soil , high winds, coastal salt-spray , and climatic conditions are often key factors in poor plant growth and development.
