The Rare Plant Rescue team coordinates with the MNDNR and local developers to salvage rare plants before construction begins. The most recent salvage was focused on the State Threatened species Black Huckleberry (Gaylussacia baccata) which was listed as a threatened species in 2013. After locating the plants, the top layer of leaves and sandy soil were carefully brushed away to expose the root systems. Staff dug by hand through the sandy soil, following the woody rhizome until it was connected to another black huckleberry plant. Whole sections of black huckleberry were unearthed, placed in water and transported to the MN Landscape Arboretum (MLA). Staff and volunteers potted the plants so they can grow in a controlled setting at the MLA throughout the summer. MLA staff also took stem and root cuttings to experiment with different propagation methods.

Plants that survive the salvage will be transplanted into a protected site in the fall. The study includes documenting the habitat type of the salvaged site, propagation methods, and rare plants previously planted at protected sites are monitored annually. Approximately 80 Black Huckleberry plants were transplanted during this recent rescue in Ham Lake.

Earlier this year, the MN Dept of Agriculture (MDA) added Amur Silvergrass (Miscanthus sacchariflorus) and Winged Burning Bush (Euonymus alatus) to the Restricted category of the state noxious weed list. It is unlawful to sell or propagate Restricted plant species and landowners are encouraged to manage their spread.

Amur silvergrass has been used as an ornamental plant in the US for over a century. It forms dense colonies that can aggressively outcompete native species. Consider replacing this species in your landscaping with showy native grasses such as little bluestem (Schizacharium scoparium), yellow prairie grass (Sorghastrum nutans), or prairie dropseed (Sporobolus heterolepis).

Winged burning bush was also introduced to the US as an ornamental shrub. While its dense thickets made it a popular hedgerow plant, they also enable it to crowd out native vegetation when allowed to spread into natural areas. Winged burning bush produces many seeds which are distributed by wildlife, allowing it to easily spread over long distances. Consider replacing this species with native shrubs such as serviceberry (Amelanchier alnifolia), chokecherry (Prunus virginiana), and button bush (Cephalanthus occidentalis).

Learn more about identification and management of these invasive species with these MDA resources on Amur Silvergrass and Winged Burning Bush.
