Transcript of Cimarron
Where is it
Cimarron National Grasslands is located in the southwest corner of Kansas.
It takes up 110,000 acres of this area.
The Santa Fe trail a route from the 1800s passes through the ecosystem.
This area was known as the Point of Rocky Ranch owned by the Beaty brothers.
What affects do humans have on the grass lands?
In 1885 homesteaders or settlers came and settled on all the open grass area. The years of farming degraded the soil.With the soil degraded many plants could not survive. In result of the plants not being able to survive the organisms that consume the plants such as pronghorn antelope won't be able to survive .
because their food supply will be cut
A positive impact humans had on the grasslands are after the the big storm in the 1930s all the topsoil was blown away. The topsoil was the main planting soil so when it was blown away crops weren't able to grow. When the government heard that there was no soil to grow crops they started a foundation to restore the soil. Most of the restored soil is now productive farm land.
What kind of environment is it?
The area is a grassland. It has semiarid, with warm summers and cold dry winters. The growing and grazing season in this ecosystem is in April and September. There is an annually precipitation fall of around 10 inches. Winds can blow up to 15 miles per hour. Summer temperatures are 77 degrees and 37 degrees in winter. There are some natural fires every year.
More precipitation falls during the summer than winter
Cimarron National Grassland receives about 10 inches of precipitation annually
About ⅓ of annual rainfall occurs in the summer months of July and August
Semiarid with warm summers and cold, dry winters
The average temperature in the summer months is 77 degrees Fahrenheit
The average temperature in the winter months is 37 degrees Fahrenheit
As a result of the climate, grass fires occur.
-Grass fires can be positive, they break down organic material and return minerals to the soil.
-Grass fires can be negative, grass fires can burn buildings and crops.
-Grass Fires affect animals, Most animals can out run the fires but some can't.
-Grass fires also destroy animals habitats.
Main Abiotic Factors That Affect The Ecosystem
Organisms that are in the Cimarron National Grassland
blue grama grass, buffalo grass, western ragweed, common sunflower, western buckwheat, western meadowlark, ferruginous hawk, golden eagle, Black-tailed prairie dogs,coyote, American Bison, Swift fox, Earthworm, Bacteria
Organisms that we think are most important to the Cimarron National Grassland
FOOD Bison are grazers, feeding primarily on grasses, sedges, occasionally on lichens and berries.
PREDATOR Wolves, bears, mountain lions, and coyotes will attack the very young calves.
SHELTER Bison form large herds on grasslands, arid plains, open forests, and river valleys.
FOOD they hunt small animals such as rabbits, snakes, birds, grasshoppers, and crickets. They also hunt very young deer, elk, antelope, and bison.
SHELTER Coyotes have a den that is scent-marked and protected, within a larger hunting territory.

Important Population in the Ecosystem-The Swift Fox
Role in the ecosystem
-The swift fox is a secondary consmer and mostly eats meat but eats some plants too.
-the swift fox is eaten by all tertiary consumers in the ecosystem and decomposers
Abiotic factors affect on population
-Grass fires can limit the Swift Fox population by a little with the amount of Swift Foxes that can't out run the fires
-Precipation helps the population to keep growing because it fills the lakes, rivers, and creeks that the Swift Fox's drink from.
-Temperature can help the population grow or cause it to decrease because the right temperature will support the ecosystem and other temperatures that are too cold or too hot can hurt the population
human effect on the population
-Humans continue to destroy the dens of swift fox's and their to use the area for their own perposes this leaves swift fox's without a home.
