  • 1. Gulf Coast Prairies and Marshes By: Mimi Wellborn
  • 2. Geography• Major Rivers: San Jacinto, Trinity, Brazos, Nueces, San Antonio• Major Aquifer: Carrizo-Wilcox• Size: 21,000 sq. miles• Land: -Near Gulf Waters: Marshes, barrier islands, estuaries, & bays -Farther West: Prairies & grasslands
  • 3. Climate• Regional average rainfall: 40-60 in/yr• East Texas rainfall average: 46 in• West Texas Rainfall average: 12 in• Regional average net evaporation rate: 16-28 in• Ranges from subtropical in the lower Rio Grande valley to moderately temperate in the northwest• Along the Gulf of Mexico it has a warm, damp climate
  • 4. Inhabitants Animals Plants-Marsh Rice Rat -Texas Madrone-Ros Eate Spoonbill -Red Mulberry QuickTimeª and a decompressor are needed to see this picture.-Black Skimmer -Wax Myrtle QuickTimeª and a-Whooping Crane decompressor -Red Chokecherry are needed to see this picture.-River Otter -Sweetgum5-Attwater’s Prairie Chicken -Green Ash QuickTimeª and a5 -Eastern Brown Pelican decompressor are needed to see this picture. -Short-leaf Pine5 -Eskimo Curlew 5-Prairie Dawn5 -Piping Plover QuickTimeª and a decompressor are needed to see this picture. 5-Slender Rush Pea
  • 5. WeatheringA. Weathering -Mechanical: Wind from the gulf -Chemical: Acid rainB. Erosion -Hurricanes have eroded away some of the regionC. Deposition -The shore of the Gulf of Mexico
  • 6. QuickTimeª and a decompressor are needed to see this picture. Catastrophic Events QuickTimeª and a decompressor are needed to see this picture. Historical Event-The Deepwater Horizon Oil Spill (April-July 2010) Largest environmental disaster in American history 11 people killed QuickTimeª and a decompressor are needed to see this picture. Many oyster reefs destroyed  Killed an alarming number of baby dolphins  Whales: may have inhaled toxic fumes  West Indian Manatee: food source was damaged
  • 7. Catastrophic Events Potential Disasters Natural Humans-Hurricanes -Oil Spill• Long coast line •Long coast line• Big region •Much wildlife• Near lots of water
  • 8. Catastrophic Events Succession• Oil-consuming microbes populations soared, helping clean up at a relatively fast pace• Air evaporates many of the oils components• Sunlight breaks the oil down
  • 9. Conservation We can help the Gulf Coast Prairies and Marshes by polluting less, specifically water pollution. When you pollute water it will most likely eventually end up in the ocean. We are still trying to clean up from the Deepwater Horizon Oil Spill in 2010. A lot of pollution in the Gulf of Mexico comes from the U.S., not just Texas. But we can work to stop water pollution in the Gulf of Mexico and protect the Gulf Coast Prairies and Marshes in Texas and all the wildlife living there.-Endangered Species:• Attwater’s Prairie Chicken• Eastern Brown Pelican QuickTimeª and a decompressor• Eskimo Curlew are needed to see this picture.• Piping Plover• Prairie Dawn• Slender Rush Pea
  • 10. Sustainability-Heat• Birds fly South• Generally tropical weather• Cold-blooded animals-Sun• Longer days = more plant growth = more animals
