A manual for the identification of the most important Canadian tree species on aerial photograhs has been completed. The choice of scale of photography, focal length, flying height, films and filters as well as ecological species characteristics and the pattern of species association are discussed in general terms. Considerable emphasis is placed on the characteristic crown shapes and branching habits or individual trees and on the role of seasonal variations as an aid to photo interpretation. The identifying characteristics of approximately forty tree species are described in detail and guidelines and keys for their identification are presented. Many illustrations, in particular stereograms at large and medium scales, are included.
