Transit Mix Concrete Co. mahogany (Cercocarpus montanus) mix will be planted on the south-facing slopes north of Little Turkey Creek, with some additional principal woody species such as pinyon pine (Pinus edulis), juniper(Juniperus monosperma), and three-leaf sumac. Gambel oak/mountain mahogany will be planted along the majority of the access road, except where the road crosses Little Turkey Creek where a riparian community will be planted. Portions of the access road pass through grassland. In these areas, it would be most successful if grassland is reseeded without the shrub species. Mountain shrubland will be planted at 336 stems/acre in the following areas using the provided proportions: • Along the majority of the access road 80% will be planted with Gambel oak, 15% mountain mahogany and 5%three-leaf sumac. • South-facing slopes to the north of Little Turkey Creek and Deadman Gulch will be planted with 75% Gambel oak, 10% mountain mahogany, 5% three leaf sumac, 5% juniper and 5% pinyon pine. The mountain shrubland mixes will be supplemented by other woody species at a rate of 200 stems per acre. This will include the three-leaf sumac (5%), at a fairly low proportion, and the Wood's rose (5%) but only to moist sites in the target reclamation area. White sagewort (Artemisa ludoviciana) (45%) and fringed sage (Artemisia frigida) (45%) are drought tolerant rhizomatous perennials that currently grow in the existing mountain shrubland in the project area and are excellent additions to mountain shrubland mix. Their drought tolerance and rhizomatous growth habit make them easy to establish and will help stabilize the soils between the woody shrub plantings. Riparian Three riparian sites will be reclaimed: the Little Turkey Creek Eastern crossing (LTC-CC-6), the Little Turkey Creek Western crossing (LTC-CC-1), and Deadman Creek crossing (DC-CC-1). Each of these currently support different communities based on elevation and other factors. As such, proportions of the riparian species will vary at each site. Given the planned change to topography adjacent to Little Turkey Creek in the quarry site, it might be expected that species composition along that riparian corridor will shift over time towards more sunlight and drought tolerant species. The predominant native cottonwood found onsite is narrowleaf cottonwood (Populus angustifolia) and the most common willow is bluestem willow (Salix irrorata), with associated coyote willow (Salix exigua). These species will be used during reclamation in riparian areas because planting the species that are naturally found on site and they will generally yield the greatest reclamation success.
