Thanks to input from Kris Abell, Coordinator of the Pennsylvania Governor's Invasive Species Council (GISC), today I added over a dozen additional invasive species to the filters:

Amaranthus rudis
Amaranthus tuberculatus
Centaurea diffusa
Cirsium palusttre
Oenanthe javanica
Stratiotes aloides
Murdannia keisak
Alternanthera philoxeroides
Actinidia arguta
Impatiens glandulifera
Ludwigia grandiflora ssp.
Avena sterilis
Glyceria maxima
Crassula helmsii

The species listed above are from a working list of 150 or so invasive species of greatest concern; these are not on the DCNR list originally used to create this project.

Thanks to the generosity of @ajewitt I've added a number of PA iMapInvasives tracked species to my Project filters. Thanks so much Amy for sharing your list with me--it's been fascinating learning which species are currently being tracked by your iMapInvasive project -- I am particularly surprised by the number of garden escapees!

After updating the filters in this project iNat collected an additional 10,000+ invasive plant observations in the Lower Susquehanna region -- WOW.
