Contribute a sighting

Help me map invasive plants across northwest and central Connecticut, including the Farmington Valley. Anyone who spots Japanese knotweed, Oriental bittersweet, garlic mustard, or Japanese barberry can add it here, and the report comes straight to me.

Every report helps show where these species are spreading. A photo and a location make it far more useful. Reports are community-contributed, so I verify each species before it goes on the map, and they stay separate from my own field transect data.

Have a batch of field photos? The photo location tool reads the GPS out of your original photos in your browser and exports them all at once, no typing required.
