Priority List Number one is the priority list and the council would like all sightings to be reported.
Not present on PEI Next is a list of species not known to exist here but the council would very much like to know if they arrive on the island. All sightings reported.
Gathering Data on Distribution The council would like to find out how widespread the species on this list are. Only report plants found in natural areas.
Horticultural Plants Some of the plants on the horticultural plants lists aren't that invasive but the council would like to know the extent that they have moved outside of the garden. Do not report sightings in yards/gardens or urban areas.
