Plant Phenology Shifts in the Tetons

Using Frank Craighead’s records of the 1970s and ‘80s, Dr. Corinna Reginos retraced the naturalist’s steps along Blacktail Butte. This phenology study is continuing under the auspices of The Nature Conservancy and GTNP led by botanist Trevor Bloom along with a team of citizen scientists. Findings indicate that many plants are blooming weeks earlier due to warmer springs.
