Summary: Outbreaks of native bark beetles can lead to conspicuous changes in a forest landscape. They’ve been present for thousands of years with occasional outbreaks, but there’s a lot we don’t yet understand about them. Exactly when and where have outbreaks occurred? How severe were they? What happened to the forest afterward? How will a warming climate influence outbreaks? On this episode of Eyes on Earth, we hear from researchers Dr. Sarah Hart and Dr. Kyle Rodman, who use Landsat to help find answers to those questions. A recent study led by Dr. Rodman used Landsat to identify the locations and severity of bark beetle outbreaks in the southern Rocky Mountains. The researchers were surprised to find smaller areas of severe mortality than they expected. Landsat can even be used to help predict patterns of future outbreaks. Dr. Zhiliang Zhu, a USGS researcher, adds his perspective of the effects of forest disturbance as well.
Guests: Dr. Sarah Hart, forest ecologist, Colorado State University; Dr. Kyle Rodman, research scientist, Northern Arizona University’s Ecological Restoration Institute; Dr. Zhiliang Zhu, USGS biologic carbon sequestration researcher
Host: Jane Lawson
Producer: John Hult
