Yellowstone National Park says it’s making progress reducing the number of non-native lake trout. 

Park and contract crews caught and killed over 280,000 lake trout from Yellowstone Lake between May and October, according to a press release Friday. The total tally is less than last year and the year before that, which is a good thing.

Yellowstone National Park has been working for over a decade to protect one of the last genetically pure Yellowstone cutthroat trout populations in the Intermountain West. Its survival is the linchpin in a complex food web that includes animals as small as zooplankton and as large as grizzly bears. The Park is optimistic in its fight against the species’ biggest threat — non-native lake trout.
