.t Transit Mix Concrete Co. not included in the reclamation plan are required for successful revegetation, appropriate revisions to the plan will be submitted to CDRMS for review and approval.The revegetation plan has been modified significantly since the original submission to address public and agency concerns and to assure compliance with rules which is provided below.This revised revegetation plan takes into account changes in slope, aspect and elevation. Therefore, to increase reclamation and revegetation success post mining, the proportions of the various species would best be varied based on these three parameters. Proposed proportions of species are based upon vegetation sampling conducted onsite by BIO-Logic during preparation of the Mexican Spotted Owl Habitat Assessment and Exhibit J. Mixed Conifer A mixed conifer forest will be replanted within the majority of the quarry area reestablishing a Douglas fir (Pseudotsuga menziesii)/Ponderosa pine (Pseudotsuga menziesii) forest. Areas south of Little Turkey Creek will have a preponderance of Douglas fir compared to Ponderosa pine, and to the north of Little Turkey Creek it will have a preponderance of Ponderosa pine compared to Douglas fir. Douglas fir is more suited to generally cooler and moister north-facing slopes, whereas Ponderosa pine is more tolerant of the hot, dry conditions on south-facing slopes. On both sides of the creek in areas where the steep walls will contour in and provide protected areas and variability in aspect and microclimate, a preponderance of Douglas fir will be planted. On the pit bottom, it is probable that Ponderosa pine with some understory shrubs such as Gambel oak (Quercus gambelii) and three-leaf sumac (Rhus trilobota) will improve reclamation success. Mixed conifer will be planted at 43 stems/acre in the following areas using the provided rates and proportions: • Slopes to the south of Little Turkey Creek will be planted with a preponderance of Douglas fir at 85% and Ponderosa pine at 15%. • The pit bottoms both south and north of Little Turkey Creek will be planted with a preponderance of Ponderosa pine at 70%, Douglas fir at 20%, with additional understory shrubs such as Gambel oak at 5% and three-leaf sumac at 5%. Mountain Shrubland As shown in Exhibit J of the July 14, 2016 permit submittal, existing vegetation communities in the quarry site vary. In particular, the south-facing slopes to the north of Little Turkey Creek and Deadman Gulch support extensive pinyon-juniper woodland and mountain shrubland, with the two communities intergrading. Mixed conifer forest to the north of Little Turkey Creek is confined to draws. Reclamation is likely to be more successful on the south-facing slopes if a mixed mountain shrubland and pinyon-juniper community is targeted.
