The term “invasive plants” usually refers to aggressive, non-native plants that thrive in our area, crowding out native plants. They have no native predators, are resistant to attack, and can re-establish themselves quickly and aggressively. They often leaf out earlier than native plants, establish tremendous seed stocks in the soil, and grow very rapidly in our climate and light regime. All invasive species are causing rapid detrimental changes to the native habitats they invade, diminishing the ability of those habitats to support native wildlife. Many invasive species were introduced as ornamentals, or as commercially important products. Successful control requires a long-term commitment.
