Management Targets

From its list of Target Species, APIPP further prioritizes species for management based on threat level, known distribution, and ability to be effectively controlled. Not all species have effective control options and others are already widespread and provide limited ability for large-scale management and/or to prevent reestablishment even if controlled. APIPP uses the scores from the New York State Ranking System for Evaluating Non-Native Plant and Animal Species for Invasiveness and PRISM Threat Ranking Forms to complete a Manageability Scoring Matrix. Those Target Species that score high in the matrix (above 42 points) are prioritized for APIPP’s ongoing rapid response and control efforts. The full list of APIPP’s management targets can be found below.

Terrestrial Management Targets Aquatic Management Targets
Knotweed species (Reynoutria spp.) Water chestnut (Trapa natans)
Giant hogweed (Heracleum mantegazzianum) Eurasian watermilfoil (Myriophyllum spicatum)
Common reed grass (Phragmites australis) Variable-leaf watermilfoil (Myriophyllum heterophyllum)
Scotch broom (Cytisus scoparius) Fanwort (Cabomba caroliniana)
Purple loosestrife (Lythrum salicaria)
Yellow iris (Iris pseudacorus)
Norway maple (Acer platanoides)
Garlic mustard (Alliaria petiolata)
Swallow-wort species (Cynanchum louiseae & Cynanchum rossicum)
Japanese barberry (Berberis thunbergii)

The program continues to provide management guidance for other lower ranking species and addresses infestations of these species on a case by case basis.
