  • The World in a Pond - Iowa Sierra Club "Changes in one ecosystem can impact others. For example, drainage of a wetland or straightening of a stream channel not only impacts that wetland or stream, it also increases the amount of water passed to otherstreams and rivers. Increased volume and velocity of water entering a stream can eliminate habitat and make it impossible for certain species to survive, decreasing biodiversity..."

    Upper & Lower Lakes, Aquatic Plant Inventories : August, 2006:

    These documents represent inventories of native and exotic (invasive) plant species done on both Yaphank lakes in August, 2006, by Scott Kishbaugh, Nate Kishbaugh, NYSDEC-DOW, and Kathy Schwager, Susan Dobbertin, Elisha Gibson, Long Island TNC.

    The main point here is that 17 native plant species in the Upper Lake, and 3 native species in the Lower Lake would be killed off by the application of the proposed herbicide (i.e., SONAR).

    No data have been presented on how long it would take for the eliminated species to return to the lakes, or if they would return at all.
