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.
