Harding High Earth Club Restoring Local River Habitat

Tucked along the Mississippi riverfront just east of downtown St. Paul, Willowbrook natural area has been many things: a fish hatchery, a public park with a ski jump, even a zoo. Now, thanks to the students of the Harding High Earth Club, it's being restored to a healthy forest.

Working with Friends of the Mississippi River, the Department of Natural Resources and other organizations, the Earth Club has been helping to return the site to a more natural state - a combination of native hardwood and floodplain forests - and having a great time in the process.

Planting The Seeds

"I like getting to know about plants, both invasive and native, where they came from and their names," said Vue Pao Her, Earth Club participant.

The "invasives" Her speaks of are primarily garlic mustard and common buckthorn, plants brought here by European settlers for gardening and landscaping. Unfortunately, they escaped people's yards and spread into the forests and prairies, where they began to crowd out the native plants that birds, pollinators and other wildlife rely on for food.

The club first began working with FMR at Indian Mounds Regional Park in 2012. The students helped plant and take care of a bluff-top prairie featuring grasses and flowers with deep roots that reduce erosion and help hold the bluff in place. Now well established, the native prairie plants also provide much needed food and shelter for birds, bees and butterflies.

Building on their Indian Mounds success, in 2014 the club headed down the bluff to work on Willowbrook, a struggling riverfront forest owned by the Department of Natural Resources and located along Warner Road.

Students began their Willowbrook restoration efforts by removing invasive species along a path and planting native seeds on the bare soil.

Early the next season, they noticed that results were mixed. Was it the timing of their invasive removal efforts? Or perhaps when they planted the seeds? Or something else altogether? They decided to investigate.

A Living Laboratory

Working with FMR Ecologist Alex Roth, FMR Youth Coordinator Kate Clayton, and DNR Regional Planner Gina Bonsignore the students developed a network of research plots in the forest, turning it into a living laboratory.

In some areas they removed all the invasive species by hand in the spring, in another they waited until fall. Then they planted different mixes of seeds.

While the project is still in its early stages, students have learned that one native species in particular does well across all of their test plots: wild rye. This native grass competes well with the invasive species, and grows in thick enough to keep them from coming back once removed.

Roth said he'll be sure to include more wild rye in seed mixes for the site, and that such information is highly valuable. While Roth may have a Ph. D. in ecology, but when it comes to Willowbrook and which plants will do well, he relies on Harding High Earth Club for direction.

"It's really difficult to predict what will work. Every site is slightly different, and the work the students from the Earth Club are doing is really invaluable," he said. "I can't imagine what we'd do without them."

In turn, Her and his fellow students enjoy working with staff from FMR and all of the restoration partners - from the state Department of Natural Resources to the City of St. Paul to the local National Park Service. "It is nice to meet new people," said Her. "And it gives us good examples of different career paths we could follow."

This spring the club returned to their Willowbrook plots, tallying up different plants and insects and removing even more garlic mustard.

The club's seen a big difference in the number of invasive species in their work areas, and enjoy making - and documenting - the positive change on their local riverfront habitat. Although young, they enjoy transforming Willowbrook into a healthier riverfront forest, for not only wildlife, but future generations to come.

"I enjoy Earth Club and working with FMR because I get new experiences, and I get to help people and clean up the river. I want a better life for our children," said club member Chao Xiong.

Note: Kate Clayton is with Friends of the Mississippi River. FMR has restoration sites throughout the metro area with many volunteer opportunities for both groups and individuals. Upcoming events are listed at FMR.org/events.
