Mammels such as sea otters, sea lions, manatees and whales can be injured from direct impact by boats traveling at high speeds. Ride at controlled speeds so you can see any animals ahead of you. Avoid area of high animal population. If you hit an animal report it to your local wildlife commission. There may be a chance to save its life.
Erosion is a concern for all shorelines including rivers, lakes, and oceans.
The slow destruction of shorelines affects the habitats of plants and animals. Near the shore avoid high speeds which create wakes and observe posted no wake zones. Wash your boat off after you use it to prevent the spread of exotic plants to other lakes and rivers. Exotics are plants and animals that are non-native to a specific area. Exotics have no natural enemies and spread easily, taking over an area to the exclusion of native species, thus decreasing important plant and animal diversity.
