Short Grass Prairie

  1. 1. Grasses: The short version By: Rosha Lewis, Mark King, Morgan Thornton, Aaron Patterson [email_address]
  2. 2. Short Grasses (Location) <ul><li>East of the Rocky Mountains </li></ul><ul><ul><li>From the east coast, the grass begin to decline in height. </li></ul></ul><ul><li>The environment begins to get so dry that, the soil holds little water. As the soil weakens, it retains little water. </li></ul><ul><li>The geographical area usually is dry prairies which are found in Montana, Wyoming, Colorado, New Mexico, and Texas. </li></ul>
  3. 3. Yellow = Short-Grass prairies
  4. 4. Climatic Conditions <ul><li>The average precipitation amounts to12.6 inches in short grass prairies. </li></ul><ul><ul><li>10 to 12 inches of rainfall a year. </li></ul></ul><ul><ul><li>The amount of rainfall determines the height of the grasses. </li></ul></ul><ul><li>North American prairies during the summer: </li></ul><ul><ul><li>Reaches 100 degrees Fahrenheit </li></ul></ul><ul><li>Short grass prairies have hotter summers and colder winters compared to tall grass prairies. </li></ul><ul><ul><li>Winters: can be as low as -40 degrees Fahrenheit and as high as 70 degrees Fahrenheit. </li></ul></ul><ul><li>Two real seasons: </li></ul><ul><ul><li>Growing season – no frost; plants can grow. (100-175 days) </li></ul></ul><ul><ul><li>Dormant season – nothing can grow, too cold. </li></ul></ul>
  5. 5. Short Grass Soil <ul><li>Soils are lighter brown than compared to mixed prairies and tall-grass ones. </li></ul><ul><ul><li>Light brown soils tell us that the nitrogen and humus content are low. </li></ul></ul><ul><ul><ul><li>Humus – partly decomposed organic matter </li></ul></ul></ul><ul><ul><li>Plants use more shallow root systems </li></ul></ul><ul><ul><ul><li>Less rainfall </li></ul></ul></ul><ul><li>The calcium carbonate layer is closer to the surface as well. </li></ul><ul><li>Drier and weaker soils in the short-grass prairies. </li></ul>
  6. 6. Plants <ul><li>Indian Grass </li></ul><ul><ul><li>A perennial bunchgrass </li></ul></ul><ul><ul><li>A warm season grass </li></ul></ul><ul><ul><li>Ideal for grazing animals </li></ul></ul><ul><li>Buffalo Grass </li></ul><ul><ul><li>A hardy grass </li></ul></ul><ul><ul><li>Common in North American prairies </li></ul></ul><ul><ul><li>Drought resistant </li></ul></ul><ul><ul><li>Tolerant to the heat and cold seasons </li></ul></ul><ul><li>Big Bluestem Grass (Turkey Foot) </li></ul><ul><ul><li>Adapted to growing in dense stands </li></ul></ul><ul><ul><li>Allows for less competition of sunlight </li></ul></ul><ul><li>Generally, the key to survival are thick deep roots </li></ul><ul><ul><li>Anchor into the soil to prevent being blown away in the wind </li></ul></ul>
  7. 7. Animals <ul><li>The Prairie dogs </li></ul><ul><ul><li>Essentially are the squirrel of the prairies </li></ul></ul><ul><ul><ul><li>Normally, squirrels inhabit trees, but in the prairies there aren’t any trees. Therefore they burrow underground. </li></ul></ul></ul><ul><ul><li>Adapted to creating guard systems </li></ul></ul><ul><ul><ul><li>Some stay outside the burrow to watch for predators while others mate and connect burrows </li></ul></ul></ul><ul><li>Adapted to a semi-arid, windy environment with few trees or shrubs. </li></ul><ul><ul><li>Many of the animals are thankful for the rodent populations and steal their burrows to survive the freezing to the sweltering hot temperatures. </li></ul></ul><ul><ul><li>They can also withstand a great range in temperature from well below freezing in the winter to sweltering heat in the summer. </li></ul></ul>
  8. 9. Biome in DANGER! <ul><li>Human Encroachment </li></ul><ul><ul><li>The large fields of the grasslands are becoming idea for farming and airways which eventually introduce industry, commercial, and recreational development. </li></ul></ul><ul><ul><li>Fires that get carried away by the wind can trap or enclose some herds and killing them. </li></ul></ul>
