TREATMENT METHODS

Slowing the spread of invasive species is a crucial part of keeping Minnesota's public parks functional and admirable to all. Examples of how Ramsey County SWCD is contributing to our goal of maintaining clean parks include mechanical, chemical, and biocontrol techniques.

Mechanical

Many invasive species can be managed through mechanical (physical) removal. Examples of mechanical removal includes, digging up the plant and clipping seed heads. Effectiveness of mechanical removal varies between species.

Chemical

Chemical controls include the use of herbicide treatments to help manage invasive populations. Effectiveness of chemical controls varies between species. See MIPN Database for more information.

Biological

Biocontrol efforts include using natural enemies of a targeted pest to reduce their populations. This idea is implemented to target spotted knapweed in Ramsey County. Click below to learn more about biological control of spotted knapweed.
