What is the prairie l.jpg
What is the Prairie?

  • Grassland

    • Usually temperate climate.

    • Usually intercontinental.

    • Relatively flat.


Prairie l.jpg
Prairie

  • The word prairie is derived from the French word “prataria”, or meadow, which probably originated with the Latin word “pratum”.

  • It was coined by the French explorers and trappers moving into Western Canada and south into the US, during the late 18th century, to describe the “sea of grass”.


Grasslands of the world l.jpg
Grasslands of the World

  • Central Africa - savanna

  • Southern Africa - veldt

  • Eurasia - steppe

  • Australia - lowlands

  • South America - pampas

  • South America - llanos


How was the prairie created l.jpg
How Was the Prairie Created?

  • Mountain development to the west created a rain shadow, which favored the establishment of grasslands over forests.

  • Drought tolerant plants persisted or immigrated from nearby.

  • Grasses thrived, creating a fuel load that could carry fire, trees, and shrubs were not able to recover as quickly.


The prairie was further developed by l.jpg
The Prairie Was Further Developed By:

  • Fire - short fire return interval.


The prairie was further developed by8 l.jpg
The Prairie Was Further Developed By:

  • Presence of large herbivores.


Slide9 l.jpg

During the Great Ice Age (Pleistocene Age) the ice sheets lapped onto the Northern Plains, but the Great Plains was the largely unglaciated region that extends from the Gulf Coastal Plain in Texas northward into Canada between the Central Lowland and the foot of the Rocky Mountains.

    • Bunch grasses grow in small clumps.

  • Cool season versus warm season:

    • C3 grasses are active when it’s cool and dormant in heat (less drought tolerant).

    • C4 grasses are actively growing in the hot summer and dormant in the winter (very drought tolerant).

    • A true photosynthetic pathway difference.

How are grasses adapted to the prairie environment l.jpg
How are Grasses Adapted to the Prairie Environment? lapped onto the Northern Plains, but the Great Plains was the largely unglaciated region that extends from the Gulf Coastal Plain in Texas northward into Canada between the Central Lowland and the foot of the Rocky Mountains.

  • Mostly herbaceous plant tissue:

    • Cheaper for the plant to manufacture every year.

  • Meristematic tissue (growth buds) are very close to the soil surface:

    • Well protected during fire, soil temperatures during a grass fire remain relatively low.

    • Difficult to graze the meristematic tissue.


More adaptations l.jpg
More Adaptations lapped onto the Northern Plains, but the Great Plains was the largely unglaciated region that extends from the Gulf Coastal Plain in Texas northward into Canada between the Central Lowland and the foot of the Rocky Mountains.

  • Regrowth of leaves and/or stems from intercalary tissue = new leaf tissue can be produced from the leaf itself, no buds involved.

  • Carbohydrates from photosynthesis are translocated to protected area beneath the soil surface in roots, rhizomes, bulbs, etc.

  • About 75% of the grassland biomass occurs below the soil surface = a large amount of stored energy.

  • Wind pollinated.


Drought adaptations of prairie grasses l.jpg
Drought Adaptations of Prairie Grasses lapped onto the Northern Plains, but the Great Plains was the largely unglaciated region that extends from the Gulf Coastal Plain in Texas northward into Canada between the Central Lowland and the foot of the Rocky Mountains.

  • Leaves – small and narrow (reduces area exposed for transpiration and heat absorption.

  • Leaves - often with pubescence (slows rate of transpiration and reflects solar radiation).

  • Leaves - deciduous .

  • Early growth period when moisture is available (Junegrass).

  • Very deeply rooted.


What is the status of the prairie l.jpg
What is the Status of the Prairie? lapped onto the Northern Plains, but the Great Plains was the largely unglaciated region that extends from the Gulf Coastal Plain in Texas northward into Canada between the Central Lowland and the foot of the Rocky Mountains.

  • Less than 1% of the tall grass prairie remains, most has been turned into cropland, or drastically changed by haying or grazing.

  • About 24% of the mixed grass prairie is intact, most has been converted to cropland or seeded to non-native forage species.

  • About 18% of the short grass prairie is intact, it has also been heavily impacted by grazing of domestic livestock.

Water rights in wyoming l.jpg

Water Rights in Wyoming care on the part of the land manager.


Water law in wyoming l.jpg
Water Law in Wyoming care on the part of the land manager.

  • Prior Appropriations Doctrine - First in time (if permitted) is first in right - Allows for regulation of water by setting up seniority of rights system.

  • Water rights that date to territorial time (pre-Statehood).

  • All water owned by State, use must be permitted.


Surface water l.jpg
Surface Water care on the part of the land manager.

  • Most old water rights are surface water - surface water is easy to develop and easy to administer?

  • “Source” can be many miles from the area where water is used - water crossing your land is not free for your use, more than likely it is already appropriated?

  • Approximately 80 “hydrographers” administer surface water rights in Wyoming. One individual covers most of Laramie County.


Ground water l.jpg
Ground Water care on the part of the land manager.

  • Domestic and stock wells limited to 25 gallons per minute by law.

  • Domestic use is defined as water for household use for 3 or less single family dwellings and non commercial garden. Landscape water of no more than 1 acre.

  • Commercial uses (including greenhouses or businesses growing for market) have additional permitting requirements.

  • Domestic and stock watering are preferred uses under State Statute, but not in State Constitution. This gray area will have to be decided by the courts when conflict between users escalates.

  • No mandatory well driller licensing program, voluntary program adopted by legislature in 2004.


Your water well l.jpg
Your Water Well care on the part of the land manager.

  • Minimum well construction guidelines

    • November 2004 State Engineer’s Office

      • working on update to 1974 minimum construction standards that are currently in place

      • 20 feet from property line

      • 100 feet from leach field

      • must have surface seal to prevent contamination - 10 ft. require by standards, few actually have seal installed.

    • Proper Construction can be important in quality and quantity of water produced (sand content, water quality, longevity of well and pump equipment).


More on your well l.jpg
More On Your Well care on the part of the land manager.

  • You are not guaranteed a static water level or artesian pressure.

  • Obtaining a Ground Water Permit does not guarantee that you will be able to construct a “good” water well. Geology dictates what is or is not available.

  • Having the oldest house on the block does not mean you have senior right. If you have a well, you should verify the status of your water right, especially if you plan to complain about your neighbors.
