As of April 2019, there are 398 invasive species being

tracked in the Pennsylvania iMapInvasives database.

All tracked species are considered invasive because they are non-native to Pennsylvania and known to cause

harm to the economy, environment, or human health.  All tracked species have either been discovered

in Pennsylvania or are known to exist in neighboring states.

Contact the state administrator if you would like to add a new species to our tracked list.
