用大比例尺（1：800- 1：1，500）70毫米彩色红外航空照片鉴别灌木明显优于用正常颜色。11个物种中有7个在彩色红外上被正确识别超过80%的时间;两个被正确识别100%的时间。在彩色照片上，有六个物种的识别率超过80%，但没有一个物种的识别率是100%。小于1：2,400的照片具有有限的价值，除非是相对较高的物种的成熟个体，并且只有当冠缘没有覆盖并且在物种和背景之间存在明显的边缘时。对于密集林分中的低生长物种，需要较大比例的照片（1：800或更大）。
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.
