Germination Success!

In 2019, The Anoka Sand Plain (ASP) Rescue Program collected MN State Threatened Rotala ramosior (toothcup) seed from a site and the collected seed was taken to the MN Landscape Arboretum's seed bank for storage and preservation. The ASP Program is always on the search for suitable habitat and the Cedar Creek Ecosystem Science Reserve has habitat, active management and a willing landowner. Bison were introduced to part of the Reserve, creating open soil disturbance with their trails and wallows. 

In fall, 2023, the ASP Rescue team spread a small amount of seed along and the area was recently monitored this spring and countless Rotala ramosior – toothcup plants were identified throughout the wetland depression. Toothcup is an annual whose population fluctuates due to changes in water levels along shorelines and wetland depression habitats and requires disturbance to create bare soil for the seeds to have space to germinate. The ASP Rescue team will continue to monitor this area to determine the results of the seeding, which will help guide future reintroduction and management efforts.

Anoka Sand Plain Rare Plant Rescue

The Anoka Sand Plain (ASP) Rare Plant Rescue Program had a busy year in 2023! Thanks to the assistance of partners and volunteers, we:

  • Rescued over 900 state threatened and endangered plants from 3 new sites!
  • Transplanted over 600 rescued plants and species from seed germination trials.
  • Collected seed from 5 rare plant ASP populations for genetic preservation in the MN Landscape Arboretum's Rare Plant Seed Bank.
  • Began stem cutting and/or germination experimentations on Gaylussacia baccata (Black Huckleberry) and Rubus sp. (Bristle-berries).
  • Collaborated with the City of Blaine to adjust land management practices around a rare population of Endangered Aristida longespica (Slimspike Three-awn).
  • Implemented follow-up monitoring of previous rescue transplants to calculate survival and record success rates of locations and methods.

Looking Forward:

  • Plants rescued in 2023 are overwintering at the MN Landscape Arboretum and will be ready to move into their new homes in 2024.
  • As habitat loss continues, we will continue to seek out and survey new suitable habitats for the rescued transplants.
  • Research efforts will continue as we expand our knowledge about these rare species.
  • Conservation plans are being developed for the rare species of the ASP, outlining methods and protocols for plant rescue and conservation.
We are anticipating additional rescue events in 2024. Please stay tuned and sign up here to join our contact list! The ASP Rare Plant Rescue Program is currently funded by Lessards-Sams Outdoor Heritage Council using MN Clean Water Land and Legacy Funds.

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.

Anoka-Ramsey Community College provides helping hands for rare plants and rare habitats

ACD staff have been collaborating with Professor Kristen Genet to create hands-on learning opportunities for an Anoka-Ramsey Community College Ecology class. The class learned about rare plants, rare habitats and the invasive species that threaten them, and provided service through their learning. The class got out to plant native grasses and wildflowers to create a dry prairie pollinator garden in a Coon Rapids park. They also conducted rare plant surveys to help guide rare plant rescue planting densities and removed buckthorn that was starting to grow into areas with rare plants. Thanks to Kristen Genet and students for all their contributions!
