Montana’s trout habitat threatened under climate change

Wednesday, September 14, 2022

As per a new study, Montana is expected to lose as much as 35 percent of its cold-water trout habitation by 2080.

Scientists from the US Geological Survey, Montana Fish Wildlife and Parks, and the University of Montana did a research regarding how climate change can impede Montana’s trout fishing trade in the approaching times.

The research evaluated more than 30 years of statistics regarding fishing inclinations across Montana, exhibiting an enormous industry growth since the 1980s, said Tim Cline, an ecologist with the USGS and the lead author of the study.

Cline said that since 1983, there has been a surge in the total quantity of angling burden on the rivers of Montana.

Trout thrive in cold-water environment, in river sections below 64 degrees Fahrenheit. With high temperatures and drought intensification with climate change, cold water environment will start shrinking by more than a third in the approaching periods, and this a loss which could cost Montana around $200 million yearly in lost tourism revenue.

According to the study, anglers can lessen pressure on Montana trout by expanding where they fish, and making use of smaller streams, as a substitute of thronging the same popular rivers.

Cline said that important outcomes in the research is that the habitat range on the landscape offers opportunities for people to find places for fishing and to preserve the fishing industry in Montana even in case of extreme occasions.
