  • Tuesday, Sept. 22, 6-8 pm, “What the vascular system of trees can tell us about responses to climate change.” Dr. John Sperry has spent his career researching how water moves through plants: from root to leaf. His research subjects include evergreen and deciduous plants growing in southwestern deserts to boreal forests and old world tropics. His microscopic research on the inner workings of plants has application to the big picture of climate change. He will translate his academic studies for the curious lay person in this illustrated program. Dr. Sperry is a biology professor at the University of Utah, as well as an avid arctic canoeist ( Co-sponsored by Teton Plants and the Teton County Library.
  • Thursday, September 24, 6:00 PM, “Climate Change Comes to Thoreau’s Walden,” featuring Dr. Richard Primack, sponsored by Teton County Library. Over the past 14 years, Dr. Richard Primack, a professor at Boston University (, has compiled a wealth of data from Thoreau’s records and contemporary observations to show how a warming world is impacting the plants, insects, and birds of Walden Pond and the greater Concord, Massachusetts area. In this talk, Dr. Primack will present his fascinating findings and consider how Thoreau would react to the modern problem of climate change if he were alive today. The presentation will include beautiful photos and numerous quotes from Thoreau. Local hosts Dr. Corinna Riginos and Dr. Geneva Chong will also discuss how they are beginning to apply some of Dr. Primack’s lessons to learn about climate change in the Tetons using data collected by Frank Craighead. For more information about the speaker and program: contact: Corinna Riginos or Geneva Chong
  • Wednesday, September 30, 6:00PM, “Climate Change, Fire, and the Future of Greater Yellowstone,” featuring Dr. Monica Turner, sponsored by the Teton County Library. Dr. Monica Turner, a professor at the University of Wisconsin and president-elect of the Ecological Society of America, is the leading expert on fire ecology in the greater Yellowstone system ( Dr. Turner will present lessons from more than three decades of research in Yellowstone about the role of fire in this ecosystem, and how that role is changing as the climate warms. Dr. Turner’s groundbreaking research has shown how the forests of Yellowstone have recovered remarkably well in the wake of the 1988 fires, proving the resilience of this dynamic ecosystem. But, warming temperatures and drier conditions are creating new challenges for the forests of Yellowstone, threatening their future. Sponsored by the Jackson Hole Conservation Alliance.

  1. Enjoyed the wildflower hike on Old Pass Road. Amy, Rachael and Jill did a great job. And as always it was fun to learn from everyone there. Plan on talking to my town to ask if I can pull/dig up some Houndstongue that I know are present (even though they are pretty). Lunch was a nice treat too.

  2. Anybody up for a hike in the next couple of days. Your choice, but I would like tram, cascade cyn, death cyn or even sheep mt.

  3. Has anyone been up Horsethief/Wilson Canyon to check out the fire? I was up a couple of weeks ago and grass was poking through the charred ground.

    • It will be interesting to go up Horsethief now to see what is sprouting. Also get out to see the Balsamroot, which is at its peak throught the southern end of Jackson Hole.!
