The Aspen Decline What will our forests in the west be like in fall without those golden yellow leaves shining in the sun? Aspen forests in the Intermountain West support levels of biodiversity only exceeded by riparian (stream) communities. In this time of Climate Breakdown, aspen have been declining due to drought and temperature stress,…

The snag forests that result from high-severity blazes are a unique and critical habitat for numerous species. Photo George Wuerthner I was backpacking with a friend up the Yellowstone River in the Teton Wilderness of Wyoming a couple of years ago. At various times, we passed through areas that had burned severely, likely in the…

Study and photos show terrific regrowth of riparian vegetation- Hart Mountain National Antelope Refuge in southern Oregon had been grazed by cattle for many decades when in 1991 the cattle were removed. The refuge had been created in 1936 as a “last stronghold” for remnant pronghorn antelope. Since that time wildlife conservation has grown more general.…

What about willows? One of the main criticisms I’ve heard is that the story fails to mention studies indicating measurable changes in willow growth. Willows, a riparian species, have really made a comeback in many areas where wolves are present and have increased the habitat for birds, beavers and fish. Elk, aspen & wolves: a…

Strong evidence that aspen groves are becoming healthier with presence of wolves. Healthier aspen groves support more bird species, which may in turn help the overall health of forests. One thing mentioned in the article is that the pine beetle infestations seen throughout the west could be impacted with greater diversity and larger populations of…
