OPTIMUM RATIO OF PHOTO-FIELD PLOTS FOR AERIAL VOLUME AND AERIAL VOLUME GROWTH REGRESSION CONSTRUCTION D.A. Stellingwerf* ABSTRACT The calculation of the optimum proportion of field/photo plots for a fixed cost ratio of field and photo plots is done for spruce in a 3000 ha forest covered region in Austria 3 considering two cases: 1) the optimum proportion for the construction of a volume table and 2) the optimum proportion for the construction of a gross mean volume growth table. Linear regression equations are taken both for the volume table and the volume growth table. In addition to standard error and cost calculation for the two cases 3 standard error and cost figures are also given for pure field plot enume rations not using aerial photographs. In the given examples the combination of photo and field plots is always cheaper than the field plots alone. However 3 additional expenses for photog raphy and. other applications of photography for management purposes should be considered in order to have a proper judgment for the use of aerial photo graphs for such management purposes. When 3 however 3 the construction of the tables for volume and growth is com plete j the application of these tables is always much cheaper than pure field enumeration.
