Walker Basin (S) 1968
Discussion of Allotment Soils

The Walker Basin (S) Allotment has six major Soil Management Units (Major classes of soil types grouped together due to their similarities). They are as follows: Brolliar-Wildcat, Hogg-McVickers, Siesta-Sponseller, Tie-Clover Springs, Springerville-Piaso, and Landforms. The soils map below shows the location of these units within the Walker Basin (S) allotment.

Landforms, although not soil types but topographic features, have been included as a soil management unit in the Long Valley Ranger Districts' Soil Report. These Landforms are mainly canyons and other types of relief features with slopes of 40% or greater. These areas are very susceptible to erosion if abused. Landforms do provide runways and "edge effect" for wildlife.

The Brolliar-Wildcat type makes up most of the eastern two-thirds of the Allotment. This Management Unit has a moderately high timber producing potential. Forage production and wildlife habitat can be medium to good on this unit. Engineering qualities vary considerably throughout this type from fair - poor - very poor.

The Hogg-McVickers types are located in the eastern central portion of the allotment. These units are well suited for timber production. Forage production potentials are medium in nature for this type. These areas can achieve a fair to good wildlife habitat. Engineering qualities are fair to good in this unit.

The Siesta-Sponseller Management Units are also interspersed through the Brolliar-Wildcat types. These areas are high timber producers with a moderately high potential for forage production. These areas can, with vegetative improvement, provide a very good wildlife habitat. This type has good engineering qualities.

The smallest types in size are the scattered Tie-Clover Springs Management Units in the Brolliar-Wildcat area. The Tie-Clover Springs Units have low timber producing potentials, with a very high forage potential. These areas' soils are very erodible. They are rated with good engineering qualities in the Long Valley Soil Report; however, the erodibility factor complicates the engineering picture. These areas can provide an excellent wildlife habitat.

Springerville-Piaso Soils Management Unit does not have a significant timber production potential; they do rate from moderate to high as forage producers. They have the lowest engineering qualities. This Unit covers the western one-third of the allotment.
