Invasive Species Removal

Invasive plant species cause ecological harm in a new environment where they are not native.  Because they have no natural predators to consume them, invasive plants can reproduce and spread rampantly. 这样做的时候, invasive plants outcompete and displace native plants and the many native wildlife species that depend on them for food and cover.

Invasive plant species not only decrease the biodiversity of native plants and animals, but they also alter the way an ecosystem functions, resulting in issues like flooding, 土壤侵蚀, and altered soil characteristics.   With careful and consistent management, 然而, we can stop invasive plants from spreading and can even completely eradicate them from a property.

What is Invasive Species Removal?

Invasive species removal involves killing unwanted plants and preventing their reemergence. How invasive plant species are removed depends on the type of plant we are targeting.

 

入侵木本植物

Common invasive trees and shrubs in our area include autumn olive, 沙洲柳树, 忍冬属植物, 还有沙棘.  These grow into thick stands that prevent light from reaching the forest floor, 尽量减少气流, in the case of buckthorn, emit a chemical that changes the soil chemistry and can be lethal to frogs and salamanders.

Look for these common invasive species:

沙洲柳树

Honeysuckle (Lonicera species)

机械去除 of 入侵木本植物

Removal of large stands of woody invasive species, like buckthorn and autumn olive, is often done mechanically. We commonly use a skid steer or mini excavator with a 林业 割草机附件. This work is best done in the winter when there is little chance of disturbing desired native plant species or compacting the soil.

在潮湿的环境中, where woody invasive species like 沙洲柳树 can dominate, an amphibious excavator with a forestry 割草机附件 is used instead. The low ground pressure of amphibious equipment allows us to work in difficult, wet sites without compacting the soil or sinking.

For smaller sites or sites too tight for mechanical equipment, invasive woody trees and shrubs are cut by hand using chainsaws.  Regardless of the method used, all stumps need to be treated with an EPA-approved herbicide to prevent the plants from growing back.

Girdling large trees is another woody invasive species removal option where we strip off the bark and cambium in a ring extending entirely around a trunk or stem, cutting in enough to interrupt the flow of sap.

Invasive Grasses and Flowering Plants

Familiar Midwest invasive grasses include reed canary grass and common reed. 大蒜芥, 川续断, 加拿大蓟, 紫色的珍珠菜, and lesser celandine top the charts of invasive flowering plants.

Depending on the species and the time of year, recommended control options include ecological mowing, det365, selective herbicide application, or a combination of methods. These control options are all used to ultimately eliminate invasive species while giving any native plants present a chance to reestablish.  正在进行的 管理 to prevent invasive species from moving in and taking back over is typically recommended.  The healthier the ecosystem, the better it can defend itself against invasive species.
