Ash grove in ͹Ƶ prairie removed due to invasive insect

͹Ƶ removed a grove of ash trees in its prairie due to emerald ash borer damage and is considering reimagining the space as an oak savannah while maintaining an environmentally sensitive approach to support wildlife and community engagement.

If you’ve walked through the ͹Ƶ prairie lately, you might have noticed changes to the southwest corner. A grove of ash trees, decimated by the invasive , was removed in the fall.

“For several years, we’ve known that our ash trees might be in trouble,” says Dr. Robb De Haan, director of the ͹Ƶ prairie. “On the east side of town, people had windbreaks where every single ash died. Last year, the emerald ash borer hit Sioux Center hard, including our trees on campus.”

De Haan, who also serves as a professor of environmental studies, biology, and community development at Dordt, took a walk through the prairie with members of Dordt’s facilities team to evaluate the situation. They determined it was best to take out the trees closest to the bike path so as to not endanger anyone, while still allowing a few dead trees to remain.

“From a wildlife point of view, standing dead trees are really valuable; woodpeckers use them, and those cavities become great spots for other species,” explains De Haan. “We also were able to save some non-ash trees, including a tamarack, black walnut, and hackberry trees.”

Now, what used to be a farm windbreak can be reimagined a bit. “Nothing is set in stone yet, but we’re talking about a number of possibilities for the space," says Vice President of Operations Fred Verwoerd." He also says it was important that ͹Ƶcomplete this work “in an environmentally sensitive manner,” in part because the ͹Ƶprairie is such a well-loved space within the Sioux Center community.

“We look forward to continuing to use this space to bless the community and to be stewards of God’s creation,” says Verwoerd.

In his Wildlife Ecology course De Haan talks with his students about the importance of interacting with urban wildlife. “Studies show that people—whether they live in town or not—appreciate being in a space that’s kind of wild, where you can find animals, birds, and wildflowers. The prairie is one of the only wild spots in Sioux Center. Also, so many people walk, bike, run, and more through that space; and as they do, they witness the different plants and species that change throughout the spring, summer, and fall months. It’s important for God’s people to interact with ecosystems like the prairie – it’s really valuable.”
