How a small church prairie helps habitat and biodiversity in the middle of Minnesota
'15 acres in the grand scheme can be quite a bit,' says Wildlife Habitat Specialist Ryan Rothstein with the Stearns County Soil and Water Conservation District.
Volunteers planted more than 400 plants and roughly 18 different species across 15 acres in late May of 2022 to maintain restored prairie land on the west-central edge of St. Cloud, Minn. About 60 volunteers of all ages participated.
Ann Gustafson Larson (speaking) initiated the project at Bethlehem Lutheran Church, where the prairie was restored about 25 years ago. “We’re doing what we can,” she said. “I’m not a scientist or anything. I’m a lover of wildflowers.” She wanted to increase the diversity of plants there to support soil health, pollinators and overall biodiversity.The project drew support from the city of St. Cloud, the Stearns County Soil and Water Conservation District and the Sauk River Watershed District.

Less than 2% of that remains, according to Ryan Rothstein, wildlife habitat specialist with the Stearns County Soil and Water Conservation District. And less than 1% of the state's savannah remains – an ecosystem with grasslands and sporadic trees.Indigenous groups managed the plains and savannas in central North America for millennia. In the last 200 years, much of the fertile prairie was converted to cropland. Restored and native prairies still benefit from human interventions, according to a 2021 article published in the journal Ecological Solutions and Evidence.

Those management practices have been replaced at Bethlehem Lutheran Church in St. Cloud with an annual round of mowing and other strategic interventions like the planting in May. Later in the season, crews planned to return to pull invasive species like Siberian elm (shown here) and some thistle varieties.Bethlehem Lutheran Church cannot do a controlled burn because the land is surrounded by housing developments and Minnesota Highway 15, Rothstein said. And there are no grazing herbivores. “Mowing does not equal grazing,” he said. “That is probably one of their biggest challenges.” Photo: Invasive Tartarian honeysuckle in the restored prairie in St. Cloud, Minn. on May 21, 2022.Funding is often another limitation in restoration projects, Rothstein said. If money were no object, groups could “throw the kitchen sink at it” and make a big impact all at once. Even if the site can’t be perfect, it can still help pollinators and song birds, he said. He typically measures success during annual walkthroughs, counting by species how many of the desired plants continue to grow.Ryan Rothstein (speaking here) wants to see more high quality habitats and protect existing habitats, despite the odds against them. “Every single day, when I go to work, we’re fighting a losing battle,” Rothstein said. “That doesn’t mean we shouldn’t try.” Restoration efforts are important for increasing the amount of habitat for sensitive species and increasing biodiversity.The 2018 Minnesota Prairie Conservation Plan recommends the state acquire more than 100,000 acres of native prairie and nearly 1 million acres of non-native grasslands and wetlands in order to protect them.“We have lost the vast, vast majority of it,” Rothstein said. “Trying to get some of that back is a goal of prairie restoration.” (Map courtesy of the Minnesota DNR)People interested in launching their own prairie restoration projects should start with a lot of research and planning, Rothstein said. Recognize your limits, the unique characteristics of the land and set realistic goals with help from existing resources like the Department of Natural Resources, nonprofit organizations and other conservation groups. It often takes a motivated person, like Ann Gustafson Larson, to make it happen, Rothstein said.

But this is one area where I can do something.” Photo: A newly planted aster catches the sunlight in the prairie at Bethlehem Lutheran Church in St. Cloud, Minn. on May 21, 2022.Volunteers returned to the Bethlehem Lutheran Church prairie to water the new plants this summer.
Story behind the story
Reporter Nora Hertel learned about the planting through the St. Cloud chapter of the Citizens' Climate Lobby, where Ann Gustafson Larson promoted the event and sought volunteers. Nora interviewed Ann before the event and interviewed Ryan Rothstein after the event. Both Ann and Ryan helped fact check the captions.
Photographer Shannon Rathmanner attended the prairie planting the morning of Saturday, May 21, 2022 and helped fact check the captions.
