South Dakota State University researchers are tackling the ecological disaster known as the “Green Glacier,” where unwanted trees are encroaching on grasslands in the Great Plains. This phenomenon started with President Roosevelt’s Great Plains Shelterbelt project in the 1930s and has now spread as far north as South Dakota. The invasion of eastern redcedar trees threatens the grassland ecosystem, leading to declines in native species and wildlife populations.
Researchers are advocating for prescribed burns as a method to control tree infestations and promote the growth of native plants. Community burn associations have formed to combat woody encroachment, with SDSU Extension receiving funding to further train individuals in prescribed burn techniques. While burns have been effective, researchers are also exploring using goats as a biological control to strip bark off trees.
Despite the grim situation faced by other states in the Great Plains, South Dakota remains optimistic in its fight against the Green Glacier. By learning from past mistakes and proactively implementing control methods, the state is taking a strong stance against woody encroachment.
