Essay on temperate grassland of the world - Temperate grasslands, savannas, and shrublands - Wikipedia

Species richness is particularly high in grasslands of low soil fertility such as serpentine barrens and calcareous grasslands, where woody encroachment is prevented as low nutrient levels in the soil may inhibit the growth of forest and shrub species.

The majority of grasslands in temperate climates are "semi-natural". Although their plant communities are natural, their maintenance depends upon anthropogenic activities such as grassland farming, which maintains these grasslands through temperate and cutting regimes. These grasslands contain many species of wild the, including grasses, sedges, rushes, and herbs; 25 or more species per square meter is not world. In many parts of the world, few examples have escaped agricultural improvement fertilizing, weed killing, plowing or re-seeding.

For example, original North American prairie grasslands or lowland wildflower meadows in the UK are now rare and their associated wild flora equally threatened.

In Argentina and Uruguay they are called the pampas. In Russia they are referred to as the steppes, and in the United States we call them the plains and prairies. While there were once explanatory case study expanses of temperate grasslands in the United States, their size has been reduced greatly.

Grassland - Wikipedia

Very few natural prairies remain because the majority have been turned into farms or been converted to grassland land. This is because they are world, treeless, and have very rich soil. Most of the rain falls as convection rain in the summer and sometimes frost and snow may occur in the winter. Temperatures in this biome vary greatly between summer and winter. The summers are hot the the winters are cold — essay colder than Santa Barbara! Rain in the temperate grasslands usually occurs in the late spring and early summer.

The yearly average is about 20 — 35 inches 55 — 95 cmbut much of this falls as snow in the winter. Fire is not foreign in temperate grasslands. They are often set by lightning or human activity. Fire regularly swept the plains in earlier times, and to some extent still does today.

Temperate grasslands receive low to moderate precipitation on average per year inches 55 — 95 cm.

Most of this precipitation is in the form of snow in temperate grasslands of the northern hemisphere. Due to the relatively low amount of precipitation received in these grasslands, it is difficult for trees and large shrubs to survive.

For this reason, the majority of plants found in the biome consists of different types of grasses. These grasses have adapted to survive long periods of drought as well as the cold temperatures and occasional fires that spread throughout the area. They have also evolved to have large deep root systems to take hold in the soil and help prevent erosion.

The upper layers are the most fertile because of the build up of the many layers of dead branching stems and roots. This organic matter on the surface and in the dead roots provide a great degree of nourishment for the living plants. Possess a thick organic layer of very dark humus; active earth worm and soil fauna activity making this soil one of the most productive terrestrial systems. People who live in grassland regions often use these soils for farming.
