About a year and a half ago I wrote about salmonids and beavers in the Lake Tahoe-Taylor Creek region, specifically about the non-native kokanee salmon (Oncorhynchus nerka) that were introduced into the region in the 1930s and 1940s as a game fish. Since then the kokanee has displaced the only salmonid native to the Tahoe basin, the Lahontan cutthroat trout (Oncorhynchus clarkii henshawi), to the point that the latter was thought to be extinct.
Fast forward several decades, and Professor Mary Peacock of the University of Nevada, Reno, has found some long-forgotten Lahontan cutthroats in tiny streams in eastern Nevada near the Utah border. This is Professor Peacock’s story to tell, not mine, and you can read about it in this newspaper article. The article has a link to the actual scientific paper, published in an open-source avenue of the Royal Society. This truly is a resurrection story!
