One of these following facts about temperate grasslands might give you much information about this semi-humid biome. Temperate grassland is a terrestrial biome whose predominant vegetation which consists of grasses and/ or shrubs. The climate is temperate and range from semi-arid to semi-humid. This grassland typically exist between desert and forests where they act as a transitional biome. Grassland are also further broken down into two groups, including prairie and steppes. Most temperate grasslands receive just 10 to 30 inches of rain each year with most of it occurring in late spring and early summer. To get to know more about it, here are some other facts about temperate grassland you might interested in.
Facts about temperate grasslands 1: Regional Expressions
Temperate Grasslands are found throughout the globe, generally in the interiors of the continents and north or south of the tropic of cancer/capercorn. The following are the major regional expressions of grasslands recognized around the globe.
Facts about temperate grasslands 2: Minor Expressions
There are smaller local expressions of grasslands as well. These include the following Australian Outback and Minnesota Cedar Creek Region.
Facts about temperate grasslands 3: Rainfall
Rainfall is generally less in temperate grasslands than in tropical savannas, although drought usually plays less of a roll effecting biodiversity than it does in savannas. Rain usually falls in temperate grasslands in the late spring and early summer.
Facts about temperate grasslands 4: Average Rainfall
There is an average of 20 – 35 inches of rainfall a year. The amount of rainfall however determines the height of grasses in the grassland. For north America, this rainfall gradient helps to divide the temperate grasslands into tall grass prairies (in wetter areas) and short grass steppes (in dryer habitats).
Facts about temperate grasslands 5: Drought
Drought plays a large role in keeping trees from taking over the grasslands. Some years receive less rain than others, just as certain seasons receive significantly less rain than others. Trees generally can not stand the lack of water as easily as grasses and thus grasses remain dominant.
Facts about temperate grasslands 6: Fire
Fire plays a big role in this biome, preserving biodiversity and keeping trees from overtaking the grasses. Lightning from large storms rolling over the grasslands ignites large grass-fires. These fires help certain plants by germinating seeds, clearing ground cover to allow rare plants a chance and by nourishing the soil with freshly burnt vegetation.
Facts about temperate grasslands 7: Soil
The soil of the temperate grasslands is deep and dark. The upper layers are the most fertile because of the buildup of many layers of dead branching stems and roots. This organic mater on the surface and in the dead roots provide a great degree of nourishment for the living plants.
Facts about temperate grasslands 8: Floral Diversity
The most common grasses include blue gamma grass, buffalo grass, Johnson grass, and various sorts of wheat and burley. Common flowers include types of asters, coneflowers,Solidagos (goldenrods), vetches, Indian blankets and sweet clovers.
Facts about temperate grasslands 9: Fauna Diversity
In North America common animals include: bison, pronghorns, deer, mice, rabbits, grouse, badgers, skunks, meadowlarks, various owls, garter snakes, rattle-snakes, red-tailed hawks and prairie dogs.
Facts about temperate grasslands 10: Biodiversity
Grasslands (temperate) are dominated by one or a few species of grasses while there are several hundred other types of grasses and non-woody flowering plants that while less abundant make up a vital part of the species composition.
Hope you would find those temperate grasslands facts really interesting and useful.
