Invasive plant observations

Invasive plant observation locations were extracted from three databases: (1) iNaturalist research-grade observations (GBIF 2019), (2) EDDMapS (University of Georgia Center for Invasive Species and Ecosystem Health 2019), and (3) iMapInvasives (NatureServe 2019). Each entry was updated with the currently-accepted and previously-accepted scientific names based from ITIS (2019). Previously-accepted scientific names were retained in the case that an invasive plant record was collected using that name. All common names were also retained. We selected only observations made prior to 2012 from states of CT, MA, ME, NH, NJ, NY, PA, RI, VT.
