On the Front Lines in the Battle Against Invasive Species: Strike Teams!

Invasive Species Strike Teams are an important part of environmental stewardship; they are the protectors and defenders of our native plants and wildlife! Invasive plants are fast spreading and can create ecological changes that crowd out native plants and alter habitats to make them unsuitable for native insects or animals. The goal of the strike teams is to manually remove these plants in areas of significance to protect our native biological diversity. A diverse landscape is healthier and more robust, better able to fend off threats and adapt smoothly to changes, such as climate change.

What is a Strike Team anyway?

The New York State Parks Invasive Species Strike Teams consist of seasonal employees who travel throughout New York State to remove invasive plants from the most valuable areas of our Parks. These teams of four camp near their project areas to accomplish the goals of the Invasive Species Program. All these removals are done with manual hand tools, such as pick mattocks, shovels, machetes and loppers. Our strike teams are always up for the physical challenge and have made incredible headway against some large opponents.

What are the goals?

Invasive Species Program staff has had many successes in controlling invasive species  by carefully selecting projects geared toward terrestrial invasives, which can be controlled manually and through adaptive management.

You can see some of our most often used tools in this photo (From L-R: the ax mattock, pick mattock and loppers), as you can see, other essential elements in their toolbox include the hard hat and gloves!

Accomplishments

Starting in 2008, six interns and volunteers assisted with invasive species removals state wide. Since 2010, State Parks has employed 46 seasonal staff to remove invasive species. In the past 5 years over 1100 new observation points were entered into the program iMap Invasives, a national database reflecting new sightings of invasives. On average, strike teams remove 19 different species per year at their project sites. Some of the native species which are protected by the invasive species program include: twinleaf, American Hart’s tongue fern, sky blue aster, cardinal flower, Chittenango ovate amber snail, the Karner blue butterfly, several warbler species, mountain mint, bushy cinquefoil, and slender blazing star.

One of the best ways to reduce invasive species is avoid introducing them in the first place. Please check what is planted ornamentally in your yard and remove plants or shrubs which are invasive and replace them with natives.
