Sampling and Estimation of Conifer Mortality Using Large-Scale Color Aerial Photography
Abstract:Methods are described for sampling and estimating mortality rates using strips of large-scale color aerial photography as the primary sampling unit. The methods have been designed to be used in situations where steep terrain and the lack of a radar altimeter make it very difficult to determine exact scale of each strip of photography. The relationship between the cumulative distribution of crown areas and the cumulative basal area distribution is used to distribute mortality rates to dbh classes. A mortality inventory of the Clearwater National Forest is discussed as an example. Forest Sci. 30:333-342.
