JACKSON HOLE, WYO – Summer is here and soon some fields and backyards will be blanketed in white once again. But it isn’t snow.
Oxeye daisy is a noxious, invasive plant that shows up in early summer. It is not from around here and it’s a real problem worldwide.
In a report to the United Nations in May, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services identified invasive species as one of the top five worldwide threats to species extinction.
Closer to home, the Western Governors’ Association passed a resolution earlier this month identifying invasive species as a top priority because of their threat to ecosystems, economies, and communities. In our community, oxeye daisy infestations reduce biodiversity and forage quality impacting native wildlife and livestock.
Teton County Weed and Pest explains: Originally brought to North America from Europe as an ornamental, oxeye daisy escaped cultivation and readily spreads and outcompetes both native and ornamental species. This species grows in dense mats, spreading by both seeds and vegetative shoots. As many as 26,000 seeds can be produced from one healthy oxeye daisy plant. Seeds are usually viable in the soil for six years, but some can remain viable for up to 38 years.
It is imperative that our community work together to reduce the threat of oxeye daisy and other noxious, invasive species. Plants do not recognize property lines, and by taking a community-wide approach we all can help manage and stop the spread of these species.
What can you do?
- Prevent the spread of invasive species by remembering to always PlayCleanGo. Clean gear and equipment before moving to a new site.
- Use certified weed free forage.
- Plant native species and seeds that are compliant with Wyoming Seed and Nursery Stock laws.
- Hand pull or treat small patches before they have a chance to establish and spread.
- Manage larger infestations to reduce the infestation and prevent them from spreading to new locations.
