COLOR FOR SHRUBS

IDENTIFICATION OF INDIVIDUAL SHRUBS WAS SIGNIFICANTLY BETTER ON LARGE-SCALE (1:800--1:1,500) 70-MM COLOR-INFRARED AERIAL PHOTOGRAPHS THAN ON NORMAL COLOR. SEVEN OF 11 SPECIES WERE IDENTIFIED CORRECTLY MORE THAN 80 PERCENT OF THE TIME ON COLOR INFRARED; TWO WERE CORRECTLY IDENTIFIED 100 PERCENT OF THE TIME. SIX SPECIES WERE IDENTIFIED MORE THAN 80 PERCENT CORRECTLY ON COLOR PHOTOGRAPHS, BUT NONE WERE IDENTIFIED 100 PERCENT CORRECTLY. PHOTOSCALES SMALLER THAN 1:2,400 HAD LIMITED VALUE EXCEPT FOR MATURE INDIVIDUALS OF RELATIVELY TALL SPECIES, AND THEN ONLY IF CROWN MARGINS DID NOT OVERLAP AND SHARP CONTRAST WAS EVIDENT BETWEEN THE SPECIES AND BACKGROUND. LARGER-SCALE PHOTOS (1:800 OR LARGER) WERE REQUIRED FOR LOW-GROWING SPECIES IN DENSE STANDS.
