Transcript of Temperate Grassland

Temperate Grasslands Temperate Grasslands in the World Temperate Grassland biomes are most known as the Great plains in North America. Given its geographic location, landlocked and flat, these grasslands are very "simple." Other locations include the Steppes of Eurasia and the Pampas. Great Plains Abiotic Features of a Temperate Grassland Climate Since existing
in temperate
climates, Temperate
Grasslands often have
temperatures ranging from
negative 20 to 30 degrees Celcius. Precipitation is
pretty average in a
grassland, with an annual precipitation
of 500 to 900 millimeters (~20 to ~36 inches)
of rain, snow, etc. Biotic Features of a Temperate Grassland Animals
(Fauna) Large animals include Elk, Coyotes, Pronghorns, Mountain Lions, Bison, Mule Deer, Whitetail Deer, etc. Small animals include Cottontails, Jackrabbits, Pheasants, Badgers, Quail, Prarie Dogs, etc. *not a Honey Badger Plants
(Flora) The plants that commonly grow in a grassland are deep-rooted, hard to kill grasses, as the name implies. The grass can grow as high as they want, if it receives enough water. Due to their hardy nature, the grasses often grow back year after year, lasting decades if the cycle continues. The deep root system of the grass can keep soil intact while maintaining its own life. Also, hardy flowers are also native to the Temperate Grassland. Examples of prairie grass include: Big Bluestem, Indian Grass, Blazing Stars, Butterflyweed, Coneflowers, Sunflowers, and so on. "Pro et Contra" (pros and cons) to a Healthy Grassland Biome Benefits Pros to a healthy Temperate Grassland Biome include the following: an abundance of various species of grass

bodies of water

mineral cycle

covered soil (no bare spots)

abundant soil life such as worms, beetles and microbes

insects, birds, rodents, and larger wildlife Downsides Cons to a healthy Temperate Grassland Biome include the following: abundance of weeds or invasive plants

invasive species come to feed off the local organisms

If all of the precipitation is absorbed, there is a higher chance of wildfires

Better ecosystem = more reproduction = more hungry organisms = more competition Sources Grasslands Biome @ http://www.blueplanetbiomes.org/grasslands.htm Asst. Google Images Land Biomes: Temperate Grasslands @ http://biology.about.com/od/landbiomes/a/aa042106a.htm
