About this Event

During the month of August, challenge yourself to learn how to identify, search for, and report your findings of specific invasive species as part of a special scavenger hunt hosted by the Pennsylvania iMapInvasives Program!

This webinar training will highlight a specific checklist of invasive species that participants will be asked to search for. Additionally, participants will learn how to document presence and absence findings in the iMapInvasives database. All species on the checklist are considered to be invasive in Pennsylvania and/or surrounding states.

Regarding the actual scavenger hunt, participants will be given the entire month of August to search their local natural areas and document their findings in the iMapInvasives database. All participants who complete their checklist will be entered into a drawing to win one of 20 FREE copies of "Pennsylvania's Field Guide to Aquatic Invasive Species".

To assist participants in identifying the species on the checklist as well as similar look-alikes, all registered webinar attendees will receive an email from the PA iMapInvasives Program with helpful online resources.

The Invasive Species Scavenger Hunt checklist will include the following terrestrial, wetland, and aquatic plant and animal species:
