While scarcity of resources<br />
may imply <strong>wo</strong>rthiness for<br />
protection, in visual resources,<br />
scarcity may serve as either a<br />
value <strong>wo</strong>rthy of preserving or, in<br />
some circumstances, exhibit rare<br />
opportunities for development.<br />
Therefore, it is critical to review<br />
the scarcity of each visual value<br />
independently and then in<br />
combination to best understand<br />
the opportunities and constraints<br />
on development or regional<br />
mitigation.<br />
2.3.1 Scenic Quality Scarcity<br />
Scenic quality scarcity<br />
should be evaluated from t<strong>wo</strong><br />
perspectives. First, note the<br />
scoring on the “Scenic Quality Field<br />
Inventory” BLM Form 8400-1, in<br />
which scarcity of scenic landscape<br />
features is documented. The second<br />
involves evaluating the level of<br />
scarcity within the full range of<br />
scenic quality values inventoried for<br />
the region.<br />
2.3.1.1 Scarcity Value within the<br />
Scenic Quality Evaluation of the<br />
Visual Resource Inventory<br />
When inventorying visual<br />
resources, scarcity is one of the<br />
seven key evaluation factors<br />
considered in the scenic quality<br />
evaluation (see Figure 4). The<br />
“scarcity factor” ranges in score<br />
from “1” for common landscapes<br />
to “5” or more for landscapes<br />
identified as “one of a kind,”<br />
“unusually memorable,” or “very<br />
rare”. A score of 5 and above, and<br />
in some circumstances 4, should<br />
be considered scarce and should<br />
justify onsite preservation or<br />
potential regional mitigation (i.e.,<br />
mitigation locations outside the<br />
area of impact).<br />
2.3.1.2 Scarcity of Scenic Quality<br />
Values A, B, and C<br />
Apart from the scenic quality<br />
rating unit scarcity score, a closer<br />
examination of individual visual<br />
resource value (A, B, and C)<br />
acreages and distribution can also<br />
provide insight on overall scarcity.<br />
The quantity and distribution of<br />
Scenic Quality A, B, and C acreages<br />
should be assessed and carefully<br />
examined. The distribution of<br />
these scenic quality classes within<br />
the Mojave Desert ecoregion is as<br />
follows:<br />
1. Scenic Quality A:<br />
653,808 acres (6.7%)<br />
2. Scenic Quality B:<br />
4,871,253 acres (49.7%)<br />
3. Scenic Quality C:<br />
4,268,449 acres (43.6%)<br />
