Rescuing Rubus fulleri – State Threatened Species

The Anoka Sand Plain Rescue team salvaged rubus fulleri just days after the snow melted and the take permit was issued. A recent development was designed to avoid impacts to natural/uncropped wetlands and leave a natural area that contains most of the rare plants on the site. However, a subpopulation of rubus fulleri was to be impacted since there was no feasible way to avoid the areas due to construction constraints. 


Staff from ACD, Critical Connections Ecological Services and the MN Landscape Arboretum salvaged whole plants and cut stems/canes. Plants were taken to the MN Landscape Arboretum where they will be potted. Stems/canes were cut into pieces ensuring each piece included a bud and was potted. The Arboretum is experimenting with different propagation techniques and will keep the rubus  on-site until the fall. At that time, plants will be transferred to ecologically appropriate protected site where they can be monitored for survival and growth.  

Root tipping – yellow circles show rooting at the base and the tip

Rubus fulleri was designated as a state-threatened species in 2013. In Minnesota, this species is restricted to the shallow wet meadows of the Anoka Sand Plain. Following a century of agricultural and residential development in this region, few high quality examples of R. fulleri habitat are known in the state. Rubus fulleri is most threatened by habitat loss, with populations becoming more isolated and fragmented. Active management, including prescribed fire and invasive species control is needed to maintain a viable R. fulleri population.

Rubus Anatomy:

Cane: a biennial, woody shoot which grows out of the perennial crowns and roots

Primocane: first year cane, mainly comprised of vegetation growth

Floricane: the same cane in the second year, bearing the flowers and fruits, then dies back


Rubus fulleri traits include canes that arch and trail along the ground. They also root tip, meaning the tip of the trailing cane grows roots into the ground.

Best Native Trees for our Changing Climate

Climate change has many impacts on the natural environment and there are many ways we can help reduce climate change. There is yet another way to help with the impacts of climate change. Planting a diversity of trees that are predicted to thrive in a changing climate will help the landscape adapt and become more resilient.

Minnesota's climate is changing. Average temperatures have increased 1 - 3 ◦F statewide with the greatest temperature increases in the winter. Total precipitation has increased with more intense rainfalls. Despite the increase in total precipitation, there have been more days between precipitation events, which increases the potential for drought. The US National Climate Assessment predicts that these trends will continue in Minnesota. By the end of the century, Minnesota will likely have the summer climate of Nebraska and Kansas (Figure 1). Plant communities and habitat types will change along with the changing climate. Most tree species northward range are predicted to shift about 300 miles by the end of the century (McKenney et al. 2007). The change in tree cover alters the understory and the habitat for wildlife. One way to help the landscape adapt and become more resilient is to plant a diversity of trees and include species from more southern areas.

US Forest Service climate change models predict these trees are likely to thrive in a changing climate in the Metro region:

Tree Species

Habitat

American elm *

Average – Moist soil, floodplains, deciduous forest, swamps

Basswood

Deciduous forests, woodland edges

Black Oak

Savanna

Black Walnut

Mixed forest, Savannas, banks

Bur Oak

Forest to open prairie

Cottonwood

Lowland forests along along lakes and streams, floodplains

Hackberry

Average – Moist soil, Hardwood forest, floodplains, river bank

Shagbark hickory

Upland dry forest

Silver maple

Floodplain forest, riverbanks

White Oak

Upland dry forest

* disease resistant needed


Consider the habitat, moisture, soil, and sun conditions when selecting trees for your property.
