At the Apex
A cougar, silent and unseen in the thick understory, is emitting a beacon from its tracking collar. “She’s close, about a hundred meters to the north,” says Beth Orning, a Ph.D. student at Oregon State University. Orning has evidence that cougar No. C216 is raising a litter in this hidden ravine.
In a Forest with Wolves
Environmental philosopher Michael Nelson is lead principal investigator for the H.J. Andrews Experimental Forest and a historian for the long-term research project Wolves and Moose of Isle Royale in Lake Superior.
Fire, grazing and logging have all caused problems when they occurred in the wrong place at the wrong time for too long and too intensely. But researchers and land managers are finding that, if used strategically, these disturbances can become tools to control weeds, prevent juniper invasion and limit the extent of wildfire.
Taking Stock of Recovery
Grazing helps to shape ecosystems, but the effects depend on management and the environment.
Forecast for Africa
In the summer of 2012, Zachary Dunn climbed onto the roof of a red-brick schoolhouse in Lela, a small village in southwestern Kenya. A crowd of children milled about on the ground, watching him attach a small weather station to the peak.
School to School
Schools in Kenya have become crucial partners with TAHMO by installing weather stations and collaborating with sister schools in Europe and the United States. In Corvallis, Adams Elementary School installed a Decagon weather station last September and has just started communicating with the St. Scholastica Primary School north of Nairobi.
