When Community Calls

Tuesday, June 28, 2016

When questions began pouring in after the Gold King Mine spill in Colorado in November 2015, Karletta Chief was there to find answers. A member of the Navajo Nation and UA an extension specialist, Chief was awarded more than $1 million to collect samples from the Animas River, which was flooded with more than three million gallons of toxic waste. Chief and her team will monitor the long-term effects on the Navajo farming families that depend on the river for irrigation.

Shoring Up Seal Beach

Tuesday, June 28, 2016

A giant hose took sediment from the bottom of Anaheim Bay in California and shot it over Seal Beach National Wildlife Refuge in a wide arc. The new sediment, added in layers, raised the entire elevation of the shore in an innovative project to restore lush wetland plants, habitat for endangered wildlife, and foraging sites for birds that otherwise would be lost to climate change and sea-level rise.

Thousands of tree cores, little rods of wood containing year-by-year information about a tree’s growth, lay forgotten in a federal storage room, gathering dust, until the collection—a research treasure trove—found its way to UA dendrochronologist Margaret Evans. To Evans, the cores represented a wealth of knowledge that had yet to be tapped­—an entirely new set of data that could help predict how climate change will affect our future forests.
