Deer mice that do not survive capture are catalogued to be available to future researchers. The critters are an initial group of what researchers call “colonizers” after a fire sweeps through. Lanier described them as “movers and shakers” right away. By the time a forest community is 20 to 30 years old, the way some of the acres burned in 1989 are today, deer mice have been replaced with red-backed voles. “They come back in right away but they don’t seem to be successful right away,” said Hayley Lanier, a University of Oklahoma biology professor. “They’re not immediately moving in and taking over where they were dominant before.”
