Help Montana by learning how to identify and report woody invasive species.
Common Buckthorn (Rhamnus cathartica)
A large shrub or small tree (6-20ft tall) that has deciduous leaves which remain green long into the fall compared to native species. It can develop into dense monocultures, reduce habitat, and outcompete native species.
Russian Olive (Elaeagnus angustifolia)
A tall shrub or small tree (up to 26ft tall) wth branches that are orange-brown in color with white-mealy hairs. Readily invades riparian habitat, outcompeting native species and alters the ecosystem.
Saltcedar (Tamarix chinensis, T. ramosissia)
Wispy shrubby growth form (3-17ft tall) that often occurs in riparian areas. Has short clusters of tiny pink flowers that cover the shrub during the growing season. Crowds out native species and chokes riparian corridors.

Reporting best practices include clear photos and detailed location information.
Woody invasive species have broad negative impacts to water quality, wildlife and fisheries habitat, agricultural production, recreation, and property values. Management is a shared responsibility among all land and water users.
