Eddy covariance flux research has relied on open‐ or closed‐path gas analyzers for producing estimates of net ecosystem exchange of carbon dioxide ( CO 2 ) and water vapor ( H 2 O ). The two instruments have had different challenges that have led to development of an enclosed design that is intended to maximize strengths and minimize weaknesses of both traditional designs. Similar to the closed‐path analyzer, the enclosed desi...

The U.S. Fish and Wildlife Service's recent recovery plan for one of the most carefully watched threatened species worldwide, the Northern Spotted Owl (Strix occidentalis caurina), recommended a major departure in conservation strategies in the northwestern United States. Due to concern about fire, the plan would switch from a reserve to a no‐reserve strategy in up to 52% of the owl's range. Fuel treatments (e.g., thinning) at...
