Natural History Wanderings

ScienceDaily reports that 82 percent of California's native fish species face the risk of extinction or having very small populations due to climate change increasing the decline of already depleted populations. The study was published online in May in the journal PLOS ONE and assessed how vulnerable each freshwater species in California is to climate change and estimated the likelihood that those species would become extinct in 100 years.

The “Top 20” vulnerable species identified in the study include Delta smelt, Central Valley late-fall run Chinook salmon, upper Klamath-Trinity spring Chinook salmon, Clear Lake hitch, Kern River rainbow trout, Central Coast coho salmon, and Southern Oregon-Northern California coast coho salmon.

Interestingly, only 19 of the 50 non-native fish species that are in California are at a similar extinction risk.
