Audubon Conservation Ranching Expands in Minnesota

Audubon Conservation Ranching is increasing its technical assist into central and southwest Minnesota. Annie Bahe, new Audubon Vary Ecologist becoming a member of Audubon Higher Mississippi River’s workforce, is a latest graduate from North Dakota State College the place she obtained her Masters of Pure Assets Administration in December 2025. Throughout her time at NDSU, she immersed herself within the science and follow of restoring rangelands and wetlands.

From monitoring long-term restoration research to learning how seasonal grazing shapes plant communities, Annie’s time at NDSU gave her a deep understanding of what wholesome grasslands must thrive. She’s now bringing that have to Audubon, serving to defend birds and the working lands they rely on by means of considerate and efficient conservation ranching.

Digging Into Her Analysis: Tackling Invasive Rangeland Species

A significant focus of Annie’s graduate analysis explored how herbicides can be utilized as a strategic pretreatment in invaded rangelands to particularly goal leafy spurge, Kentucky bluegrass, and clean brome.

Leafy spurge, an invasive perennial forb, poses a severe problem for ranchers. Not solely is it unpalatable to cattle, it additionally spreads quickly and outcompetes native vegetation. Annie discovered that broadleaf-specific herbicides can suppress leafy spurge for no less than two years, usually with out harming surrounding native crops. This makes herbicide a useful software when used fastidiously and deliberately.

However invasive cool season grasses like Kentucky bluegrass and clean brome inform a unique story. These species provide respectable early-season forage, but they regularly dominate pastures, pushing out warm-season natives that present essential habitat and higher summer time grazing potential. Sadly, herbicide isn’t an efficient resolution right here. Herbicide remedies usually hurt the broader plant neighborhood whereas failing to meaningfully scale back the presence of those grasses, so different administration strategies are sometimes wanted.

Fireplace + Grazing: A Highly effective Combo

Rotational grazing mixed with spring or fall prescribed fireplace, practices usually utilized in conservation ranching, are efficient methods to handle the unfold of Kentucky bluegrass and clean brome. Rotational grazing helps scale back stress on native crops, giving them the remaining they should rebound and compete. Prescribed fireplace, whether or not utilized in spring or fall, removes the thick litter mats created by Kentucky bluegrass and clean brome, opening area for native species tailored to fireside. Collectively, these practices create the disturbance patterns that native grasslands advanced with, serving to them reclaim floor from persistent invasive cool-season grasses.

Extra Insights: Timing Issues

Throughout her time at NDSU, Annie additionally contributed to a challenge inspecting how the timing of grazing impacts clean brome. Over a number of years, spring-only, fall-only, and mixture grazing remedies all helped scale back clean brome tiller density. Constant cool-season grazing can step by step suppress clean brome and create higher circumstances for native species to ascertain.

Bringing It All Again to the Ranch

Annie is keen to place her analysis and discipline expertise into motion by supporting producers throughout Minnesota. Her objective is to assist ranchers handle their grasslands in ways in which increase forage productiveness, enhance ecological well being, and create important habitat for grassland birds.
