How does rotenone affect the environment?
A. Rotenone is non-persistent so there is no accumulation in the water, soil, plants, or surviving animals. Because it breaks down so rapidly, its environmental significance does not extend beyond one year. For example, populations of aquatic invertebrates that have been reduced may take from several months to one year to recover to their former numbers. Surviving organisms will grow and reproduce at an accelerated rate due to reduced competition. While adult frogs and other amphibians would not be seriously affected, tadpoles and juvenile salamanders probably would be killed. For these species, it would be the next breeding season before more animals would be produced and the populations would be slower to recover.
