Researchers Project New Salmon Habitat Due to Melting Glaciers
A study of potential new Pacific salmon habitat in western North America as a result of glacial retreat through the year 2100 poses benefits to salmon, but also warns of the need for forward-looking management decision making and conservation planning.
The study, published recently in the journal Nature, projects that by the year 2100 glacier retreat will create 6,146 kilometers (3,818 miles) of new streams accessible for colonization by Pacific salmon, of which 1,930 km (1,200 miles) have potential for spawning and juvenile rearing within 18 sub-regions.
“With climate change, the distribution of habitat of salmon in the future is probably going to be different than the distribution for salmon now, because of changes in temperature and precipitation which affect stream flow,” sai...
