Vegetation: The following tables from the Soil Conservation Service soil survey provide the typical yields and plant species composition for the soil units. Soils unit 66 does not have tabled values for plant species or production. Unit 66 is a typical pinon/juniper vegetation association. Production is limited on pinon/juniper stands dependent on the density of the pines and junipers. This unit consists of cliffs and very steep south and west facing slopes generally lacking significant stands of vegetation. Therefore, information related to production and plant species composition for soils unit 66 is not germane to future site reclamation.
