Dogs can disturb or injure wildlife and, in turn, can be injured by other animals. Take care not to disturb or alter wildlife habitat. A dead tree trunk or hole in the ground may be home to many kinds of wildlife. Make observations and document evidence of wildlife, plants, and other organisms, but don't remove eggs, nests, organisms, or whole plants. If you feel the need to sacrifice plant or macroinvertebrate specimens for better identification, please do so sparingly.
Plants provide food and shelter for wildlife and macroinvertebrates.
Macroinvertebrates are food for fish, birds, frogs, and salamanders. The Stream Put any rocks and woody debris you remove back into the stream. They are habitats for fish, bugs, and plants. Know what kinds of fish live in a stream and their life histories. Know when they spawn and when young fish emerge from the gravel streambed.
