Under the right conditions, some non-native plants can become invasive. Non-native Invasive plants can outgrow, replace, and otherwise destroy our native plants. That's because non-native plants usually do not have their natural enemies; the diseases, insects and other environmental stresses, that keep them in check in their native ranges. The destruction and replacement of our native plants has several significant consequences: Our natural biodiversity is destroyed; Our native plants can be eliminated; Our wildlife have evolved to use native plants are not able to make use of non-native plants. As a result, they leave the area or die off; invasive plants can completely fill the water column or cover the surface so that fish are driven from the area; swimming, boating, hiking and other uses can be affected or even dangerous in areas with invasive plants.
Chemical control is the use of specially formulated herbicides to kill plants. (Registered with the U.S. EPA and the Florida Department of Agriculture and Consumer Services)
Biological control is the use of imported insects, fish and other organisms which eat or infect or otherwise keep the invasive plants at low levels indefinitely. Before releasing such organisms, the USDA and the Florida Department of Agriculture and Consumer Services must verify that insect bio-controls have proven to be host-specific. Mechanical control is the use of specially made machines to "harvest" invasive plants by cutting and collecting them and transporting them to a place to decompose. Physical control includes using hands, draw-downs (water removal), flooding, burning, dredging and shading to control invasive plants. Integrated control is the use of two or more of the above methods.
