The goal of this experimental study was to investigate the immediate effects that canopy reduction treatments have on spotted owls.
The harvest treatments are relative in size and magnitude of those proposed under the Sierra Nevada Framework management plan. Radio telemetry was used to monitor the nighttime movements of birds over a 2 year time span, with treatments occurring in the fall of the first year of monitoring.
