Pennsylvania Native Species Day

Observed on May 20 each year, the Council created Pennsylvania Native Species Day to celebrate the state’s diverse native species and increase Pennsylvanians’ understanding of the importance of protecting them against the proliferation of invasive species.

Why protect Pennsylvania’s native species?

Pennsylvania is home to a diverse array of native plants, trees, insects, fish, birds, and mammals that originated thousands of years ago and thrive in mutual dependence. This native ecosystem provides Pennsylvanians with natural resources that benefit our lives by enabling agricultural food production, recreation, fisheries, timber, and more.

As humans have increased worldwide commerce and travel, non-native species have crisscrossed the world with us. When species are transported to areas outside their native range, they have no natural predators. They often invade, crowding out and threatening the survival of native species. Thus, the protection of the Commonwealth’s native plants and animals is critical to a healthy economy, a functioning and biodiverse ecosystem, and the health and well-being of Pennsylvania citizens.

In 2026, the Council and partners are holding an event in the Capitol Building in Harrisburg on June 1 to interact with state leaders about the importance of our native species and the need to manage invasive species that threaten them. All are welcome to attend. For more details, please contact Council Coordinator Kris Abell at krabell@pa.gov.
 

Pennsylvania Native Species Day will be observed on Wednesday, May 20, 2026.

The Governor’s Invasive Species Council created Pennsylvania Native Species Day to celebrate the state’s diverse native species and increase Pennsylvanians’ understanding of the importance of protecting them against the proliferation of invasive species.

The Council encourages interested individuals and organizations to host their own local event to help celebrate this special occasion. Events can occur on May 20, or at other times during the months of April, May or June. Possible activities could include a:

  • Native plant sale or festival
  • Guided hike
  • Guest speaker presentation
  • Workshop or webinar
  • Native species planting event
  • Invasive species pulling event

 

Please tell us about your planned event by completing the 2026 PA Native Species Day Participation Form. Information received may be used on the Council’s website to aid in promotion of Pennsylvania Native Species Day partner events.

Social media is also a great way to help celebrate. Consider posting about the importance of our native species and the need to manage invasive species that threaten them. View and download sample posts that can be used as-is, or as templates for your own original post(s).
