Aerial photographs show range conditions: When taken to proper specifications, photos aid in estimating animal-carrying capacity
1961
R Colwell
The volume and species composition of herbage on a range are major factors governing its animal-carrying capacity—the number of animals of any given type that can be grazed on the range for a given period of time. Important differences in range herbage can be detected on small-scale aerial photographs, mainly on the basis of differences in photographic tone or color.
