Primary Areas of Concern
Main
Through an evaluation of the data collected in
our route survey, Friends of the Inyo has identified 14 areas of critical
concern on the Inyo National Forest. We ranked these "hotspots"
by considering 3 factors: 1) the severity and 2) the extent of
resource damage present and 3) the potential for future resource damage.
Severity, or the quality of damage (i.e. how bad was it?) was considered the
most important factor in identifying a critical area. Thus, the severity value
was weighted (multiplied by two) to reflect its importance in our
consideration. Gauging the extent of the damage involved estimating the
quantity of the damage (i.e., how much area did the damage cover?). To
rank an area on the potential for damage, we assumed a continuation of current
management practices (with no changes, either positive or negative) and, based
on data about the effects that ORVs can have on resources, extrapolated into the
future to estimate the level of further damage. We rated each factor (on a
scale of 1 to 5) for each area and took the cumulative effect of the 3 factors
to determine the total number for an area. The following chart consists of the
name of each area, its location by USGS 7.5" quadrangle, the resource
damage issues, a summary of our ranking system and suggested recommendations for
improvement.

Lower Black Canyon
(T21) |
 | Route travels directly through riparian corridor and springs. |
 | Significant damage to riparian vegetation, cutting of vegetation and
stream capture. |
|
 | Ideally, restore this route to its original condition or
re-route T21 around critical riparian habitat. If not possible, at
minimum, stabilize the crossing to negate the stream capture, allowing
the creek to flow in its original channel. |
