the great plains general information

The Great Plains is the broad expanse of flat land, much of it covered in prairie, steppe and grassland, that lies west of the Missouri River and east of the Rocky Mountains in the United States and Canada. This area covers parts, but not all, of the states of Colorado, Kansas, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, and Wyoming, and the Canadian provinces of Alberta, Manitoba and Saskatchewan. The region is known for supporting extensive cattle ranching and dry farming.

abiotic factors

In general, the Great Plains have a wide variety of weather through the year, with very cold and harsh winters and very hot and humid summers. Wind speeds are often very high, especially in winter. Grasslands are among the least protected biomes.[10] Humans have converted much of the prairies for agricultural purposes or to create pastures. The Great Plains have dust storms mostly every year or so.

The 100th meridian roughly corresponds with the line that divides the Great Plains into an area that receive 20 inches (510 millimetres) or more of rainfall per year and an area that receives less than 20 in (510 mm). In this context, the High Plains, as well as Southern Alberta, south-western Saskatchewan and Eastern Montana are mainly semi hot steppe land and are generally characterised by rangeland or marginal farmland. The region (especially the High Plains) is periodically subjected to extended periods of drought; high winds in the region may then generate devastating dust storms. The eastern Great Plains near the eastern boundary falls in the humid subtropical climate zone in the southern areas, and the northern and central areas fall in the humid continental climate.

Many thunderstorms occur in the plains in the spring through summer. The southeastern portion of the Great Plains is the most tornado active area in the world and is sometimes referred to as Tornado Alley.


there is a decent amount of animals in this area. there are producer's that make the food for the consumers. there is not a high level of biodiversity but there is not a low level of biodiversity either.

The Great Plains belongs to the temperate grass land biome. So does the pan Handel plains

Human influences

There is a lot of space for animals in the temperate grassland biome but there developing a lot of it that is in America

General information about the pan Handel plains

This region has mostly flat, grassy land or plains. These plains are part of the same flat grassland that extends from the Great Plains of the Central United States. Sometimes this land is also called the Llano Estacado or “Staked Plains.” The land is mostly treeless and is on a high, flat plateau. The eastern part of the Panhandle is not quite as flat. It is lower in elevation and called a rolling plain. There is more rainfall in this eastern half and it is brushy.

The western and eastern parts of the Panhandle region is strikingly divided by deep canyons carved by rivers and their tributaries that wind their way through this area.

Palo Duro Canyon and Caprock Canyons State Parks are in this region. The remarkable canyons were carved by rivers. They are sometimes called "inverterted mountains" since the land is relatively flat until you reach the long and steep canyons in the ground.

There is a lot of animals so it has a high level of biodiversity

Biome and human influences

The biome is temperate grassland. The human influences are that there is development in some parts of the pan Handel plains
