control/management
What are Invasive Plants??
Reproduce rapidly Spread over large areas Few, if any, natural controls Share important characteristics
Spread aggressively by runners or rhizomes Produce large numbers of seeds that
survive to germinate Disperse seeds away from parent plant via
wind, water, wildlife, people
How do invasives impact the local environment??
Displace native plants including some very rare species
Reduce food and shelter for native wildlife
Eliminate host plants of native insects
Compete for native plant pollinators Affect recreational activities
