<ul><li> Slide 1 </li> <li> Wetlands What are they? Why are they important? How are they threatened? What we can do. </li> <li> Slide 2 </li> <li> What is a wetland? A wetland is land that is wet most of the year, but that is not enough. A wetland has hydric soil. Hydric soil is wet or moist soil low in oxygen, but that is not enough. A wetland has hydrophytic plants, plants that grow in wet, low oxygen environments. Now we have a wetland. </li> <li> Slide 3 </li> <li> A wetland is wet most of the year. </li> <li> Slide 4 </li> <li> A wetland has hydric soil. A wetland has hydric soil. </li> <li> Slide 5 </li> <li> These cattails are hydrophytic plants.. </li> <li> Slide 6 </li> <li> Other hydrophytic plants that live in hydric soil.

It has grasses and small shrubs. We have marshes in Spring Lake. </li> <li> Slide 10 </li> <li> A swamp is a wetland with shallow water covering a large area of land, that can have areas of woody plants and tall trees. </li> <li> Slide 11 </li> <li> A bog is wetland composed mostly of dead plant material called peat. Its soil is very acidic. It relies solely on rain water. </li> <li> Slide 12 </li> <li> A fen is similar to a bog but can be less acidic because it gets water from other sources running into it and also out of it. </li> <li> Slide 13 </li> <li> Why wetlands are important 1. Wetlands help reduce flooding. 2. Wetlands help keep our waters clean. 3. Wetlands provide wildlife habitat. 4. Wetlands provide natural spaces for recreation. </li> <li> Slide 14 </li> <li> Wetlands help to reduce flooding by acting like a sponge to absorb excess water. </li> <li> Slide 15 </li> <li> Wetlands help keep our lakes and rivers clean by absorbing and filtering out and storing pollution before it gets to the water. </li> <li> Slide 16 </li> <li> Wetlands provide habitat for insects, fish, amphibians, birds and mammals. </li> <li> Slide 17 </li> <li> More wetland wildlife. </li> <li> Slide 18 </li> <li> Wetlands are places to enjoy. These people are bird watching. </li> <li> Slide 19 </li> <li> Here are people canoeing and kayaking. </li> <li> Slide 20 </li> <li> Wetlands are beautiful places to walk. </li> <li> Slide 21 </li> <li> Wetlands are interesting places to study. </li> <li> Slide 22 </li> <li> But our wetlands are threatened! About half the wetlands in the USA have been lost to agriculture and commercial development. This is done by draining the wetlands. </li> <li> Slide 23 </li> <li> Disturbed wetlands are also under threat from invasive species, like Phragmites. </li> <li> Slide 24 </li> <li> Here is what you can do to help protect the wetlands: 1. Share what you learn today with your classmates and family. 2. See if you can locate wetlands, and spend time watching their seasonal changes. 3. Include wetland protection on the agenda of environmental groups you may join. </li> <li> Slide 25 </li> <li> Brought to you by:. </li> </ul>
