Abstract

An Aerial survey using an operation recorder was made over a remote forested area of the Sierra Nevada, in central California. Data on insect-caused mortality were gathered. The survey saved several man-weeks of costly ground work that would have otherwise been required to obtain this information. The technique used proved to be an efficient and inexpensive way of collecting data for forest management decisions.
