A noted Alaskan wolf biologist has been killed in a plane crash in a remote area of Denali National Park and Preserve. The pilot, though he suffered burns, was able to walk out and alert authorities.

Scientists working in Denali National Park suspect that melting permafrost might be an important reason why many of Alaska’s shallow lakes and wetlands have shrunk or disappeared. If the trend continues, wetland-dependent wildlife might be severely impacted.

Several new short trails are being proposed at Denali National Park to help protect park resources, improve visitor safety and add additional recreational and interpretive opportunities. The park is now accepting public comments on the plan. Here's a summary of the project.

Caribou have been on the landscape for more than 400,000 years. For roughly the past 12,000 years, they have been hunted by humans — first the paleo-Indians, now the First Nations’ cultures along with many other Alaskans. Resilience to hunting, to weather, and to predators has enabled the caribou to remain an integral part of both the natural landscape and the human culture. The greatest test of their resilience, though, stands to be climate change.
