Volunteers At Work: Removing Brookies on Soda Butte Creek

After years of cutbacks in natural resources funding, U.S. national parks need all the help they can get. That’s where volunteers come in, say Yellowstone Park scientists. Lauren Russell writes about the task of catching — and removing — non-native brook trout from Soda Butte Creek.
“[I]f the volunteers come across a concentration of brook or brown trout, Voigt can mark the spot using GPS technology, which park biologists can then use to find the population and remove it.”
