Invasive plant species pose a serious threat to native riparian plant communities. Furthermore, some invasive plants, such as autumn olive (Elaeagnus umbellata), fix atmospheric nitrogen and release it into the soil where it readily leaches into waterbodies. Many invasive plant populations can be found in riparian buffers throughout North Carolina. Invasive plant populations can often be successfully controlled using a variety of mechanical & chemical techniques. Large advances in native plant community success can typically be made in one to two years of invasive plant control efforts. Wildlands’ Land Stewardship Team has the skills and knowledge to identify and safely treat invasive species around aquatic environments.
While woody invasive species are best treated in the fall when they send nutrients to their roots to prepare for winter, herbaceous plants are best treated during the growing season before they set seed. Below are just a few common invasive herbaceous plants that are best controlled in the spring.
