Undergraduates from Little Bighorn College are taking a preliminary look at the problem on the Bighorn though a summer research program sponsored by NASA.
“The whole thing has to do with global warming and climate change,” explained Roy Stewart, who is leading the small group of students. “NASA was looking for projects that affect the environment. This tree affects the environment.”
In four weeks of research, the students plan to set up 10 plots along the river, Stewart said. He and the students are trudging through groves of the thorny invaders mapping likely plots with GPS and GIS (Geographic Information Systems) technology.
