Assessing the Responses of Caribou to Changing Habitat Conditions in the Arctic

Caribou roaming the Arctic Coastal Plain

Date: April 25, 2024 
Time: 11:00 a.m. (AK Standard Time)
Presenter: Heather Johnson, Research Wildlife Biologist
Abstract: Recent declines in several barren-ground caribou herds across North America have coincided with the ‘greening of the Arctic’, raising concerns about the influence of changing summer habitat conditions on caribou populations. The short Arctic summer provides caribou with important forage but is also the time they are exposed to intense harassment by insects, factors which are both being altered by longer, warmer growing seasons. Additionally, the summer ranges of barren-ground caribou in Alaska often overlap areas targeted for energy development, compounding concerns about the resilience of caribou to changing conditions. This talk will highlight recent research by USGS and our partners to better understand the influence of summer habitat and human development on caribou behavior and demography in the Alaskan Arctic, with implications for how populations may be impacted in the future.

Location: Leslie Holland-Bartels Conference Room, Glenn Olds Hall Building, 4210 University Drive, Anchorage (Click here for a map). Please park at the Carr-Gottstein Building.
