Invasive Species Program

The Invasive Species Program was created to assist with the management of invasive species within the Raleigh Parks System. The program serves as a resource to manage infestations, prevent introductions, and provide educational opportunities to all citizens. Interested individuals and groups can volunteer to assist with managing the invasive species in our parks.

What are Invasive Species?

Volunteer helping Raleigh parks staff clear invasive plants

Invasive plant species are non-native aggressive plants that threaten and degrade our ecosystems. Fast-growing and reproducing quickly, invasives shade out native plant seedlings, smother trees, and outcompete for resources such as light, water, and soil nutrients. By preventing native species (even oaks!) from growing, invasives prevent native birds and other animals from completing their life cycles. This changes the profile of our forests and open spaces.

Invasive Plant Species

English ivy growing on tree trunks — English Ivy

Tall green johnsongrass in field — Johnsongrass

Brown wisteria vines overgrown over other trees in the woods — Asian Wisteria

Green privet plant vines growing over other trees in woods — Privet

Many invasive plants in Raleigh are evergreen and produce a lot of pollen, creating safety hazards for people such as visual obstructions along our greenways and roads and health hazards during peak pollen seasons. Preventing, removing, and monitoring for new infestations are important steps to maintain the ecosystem and human health.
