Why report invasive plant species?
This information is used to determine how a species range is moving and will influence if the species will be added to the MA prohibited plant list.
When to report?
If you have found an early detection species tracked by the MA Dept. of Agricultural Resources (see their current priority list here), report it to MDAR. These species are known to be problematic and are a high priority to prevent their establishment.
If you found a non-native species or you are at the edge of species range report the sighting to iNaturalist on your phone or EDDMapS.
CISMA partner OARS is tracking water chestnut to prioritize pulling efforts. Report seeing or pulling water chestnut here.
