3 Environmental report card Decide the format of your environmental report  Booklet  Poster  Certificate

4 Habitat factors Bank erosion and stability In-stream cover Verge vegetation Bank vegetation

5 Habitat factors Riffle Pool

6 In-stream cover: Fish and other aquatic organisms require snags, logs and rocks where they can shelter for predators and the current. Verge vegetation: Vegetation growing on the section of land up to 30 meters from the water’s edge. Bank vegetation: Trees, shrubs, grasses, ground covers that grow on the bank. Habitat factors

7 Wetland organisms Bank erosion and stability: Streams naturally erode, usually on bends.
