Riparian Buffers & Pollution

Riparian buffers, consisting of strips of vegetation alongside streams and rivers, play a crucial role in maintaining clean water supplies. They function by limiting pollution flow into waterways, slowing floodwaters, cooling water temperatures, reducing sediment erosion, and providing vital habitat for wildlife. Understanding the differences between point source and non-point source pollution is essential. This guide helps to illustrate how human actions impact water quality through these pollution types, emphasizing the need for riparian buffers to sustain healthy aquatic ecosystems.

Presentation Transcript

  1. Riparian Buffers & Pollution

  2. LEQ: • In what ways can humans help maintain a clean water supply?

  3. Riparian Buffers! • WHAT? Strips of vegetation (trees/plants) next to streams and rivers

  4. Why?? • 1. Limits flow of pollution into water

  5. 2. Slows floodwater

  6. 3. Provides shade; cools the water

  7. 4. Limits mud and sediment from flowing into water preventing erosion.

  8. 5. Provides habitat for animals

  9. No Riparian Buffer Riparian Buffers Rule!

  10. Lets Review 1. Fold paper into 4. 2. In each box, draw a quick symbol/picture to represent what a riparian buffer is or does.

  11. Water Pollution When chemicals or other harmful substances enter our water supply

  12. Point Source Pollution • An identifiable source of pollution that directly enters the water • Ex. Pollution being dumped into a river via a pipe from a factory • Ex. Directly dumping trash into a river

  13. Non Point Source Pollution • Pollution that INDIRECTLY enters our water through run off • Spread out over large areas • Example: Fertilizers from lawn washed into a river with the rain

  14. Point or Non point? • Ask yourself: Did this enter the water by runoff? Yes? Non pointNo? Point

  15. Label your paper 1-7.Hint! Ask yourself: Did this enter the water by runoff?1. Point or Non Point?? WHY?

  16. 2. Point or Non Point? Why?

  17. 3. Point or Non Point? Why?

  18. 4. Point or Non Point? Why?

  19. 5. Point or Non Point? Why?

  20. 6. Point or Non Point? Why?

  21. 7. Point or Non Point? Why?

  22. Assignment • POLLUTE acrostic
