For Everything There Was a Season: Retracing Craighead’s Footsteps

Scientist/guide Trevor Bloom will explain how shifts in plant and animal life cycle events reveal how climate has changed in the Greater Yellowstone Region.

Bloom works as a phenology scientist for the Nature Conservancy in Wyoming. Phenology is the study of periodic plant and animal life cycle events and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors, such as elevation.

He also owns and works as a naturalist guide in the greater Yellowstone area for Guides of Jackson Hole. Beyond science and guiding, Bloom produces short films, including his newest documentary, “Climb-it Change,” which reveals the impacts of climate change on alpine ecosystems through an adventure traversing the entire Rocky Mountain chain, rock climbing and summiting 76 mountains.
