INDICATORS OF SOUTHWESTERN RANGE CONDITIONS 29
IMPORTANT POINTS CONSIDERED BY EXPERIENCED RANGE JUDGES
Obvious, but nevertheless important, is the reminder that a range
cannot be fairly judged unless a fair sample of it is seen. Topography,
vegetation, and use can rarely be estimated from the principal
travel routes. The aim should be to observe conditions distant from
roads and trails as well as adjacent to them; farthest from watering
places and also nearby.
In arriving at their conclusions experienced range examiners give
particular weight to a few outstanding points.
HISTORY OF PAST AND PRESENT USE
More accuracy in sizing up any range always follows a close study
of its history. What did the range look like 15, or 40, years ago;
what changes have occurred in recent years (1) in kind, vigor, or
abundance of plants, (2) in size of forage crop, (3) in timber growth,
and (4) in extent and degree of soil erosion? In other words, is the
present vegetation essentially stabilized or changing?
With reference to these points, the experience and remembrance of
reliable old-timers should be consulted freely and their testimony
considered along with other evidence. Much evidence concerning
changes often may be obtained from burns; for example, charred
juniper stumps can still be found on certain brush ranges which are
not supporting a tree growth now. And, again, comparisons with
ungrazed or well-managed areas are almost essential.
How does present stocking compare with past stocking? All available
records, and other sources of information, should be consulted
and analyzed in the attempt to determine fluctuations in numbers of
livestock and actual periods of past grazing.
How does present handling compare with former handling? Puzzling
questions relating to the looks of a range can often be explained
when one learns of some radical change within the last few years,
either in the kind of livestock or in their handling.
KIND OF RANGE
In considering the factors of topography, soil, and vegetation lands
may conveniently be classified for broad inspection purposes, as follows:
Short-grass ranges (fig. 1); meadows, locally called "cienagas"
(figs. 28, 33); bunchgrass ranges (figs. 17, 29); brush (or browse)
ranges (fig. 20); desert ranges (fig. 3); mixed types (figs. 2, 7).
Topography and Soil
A degree of use that may be satisfactory on level or undulating land
usually becomes dangerous use in rolling country and destructive overgrazing
on ranges of steep rough slopes (figs. 1, 2, 3).
A closeness of use that would be safe on heavy, compact, rockstudded
soils, for example, will usually be destructive on loose, ashy
soils. After soil washing once starts in deep clays or clay loams,
gullies are apt to continue eating back long after the original causes of
their beginning have been removed, unless soil stabilization can be
hastened by check dams or other artificial erosion-control structures.
In such deep soils the erosion damage is not so permanent and far
