• Supplemental irrigation for the tali shrub mother plants will be provided at the time of planting
• and after that only when soil moisture is low (typically August and Septemberl. The sites will
be flood irrigated with a water truck using gated pipes and furrows. Supplemental irrigation
will be maintained for two years after initial planting.
The follovying shrub and tree planting lists include a selection of trees and shrubs for specific
planting areas or sites. The planted species will provide a basis for the eventual
reestablishment of woody plant communities, restore habitat, and enhance plant community
diversity, pattern, and structure. The plantings are not intended to restore woody plant
communities on a large scale basis in the mine affected areas. However, the species selected
for the various planting areas (Table 22-7, Shrub and Tree Planting Lists 1-61 are native to the
area or region and will be able to spread and colonize new areas over time.
Many of the plantings will be made in the larger open blocks of the reclaimed area to promote
the potential for woody plant development and mitigate wildlife habitat loss. Development of
wildlife corridors was also a consideration in these planting locations. Other plantings were
located to specifically mitigate more critical habitat such as along Dry Creek, or enhance
existing habitat around the permanent ponds. Exhibit 22-t and 22-1A illustrates the
approximate locations of these woody planting areas, while the planting lists represent the
species to be used in the various planting locations.
• Natural regeneration of shrubs, particularly big sagebrush and mountain snowberry, has played
an important role in woody plant reestablishment at the Seneca II Mine to the east. Natural
regeneration is also anticipated at the Seneca II-W and II-W South Extension areas
Complimenting natural regeneration will be the inclusion of shrub seed in the seed mixes and
the establishment of concentrated shrub seeding areas where competing herbaceous vegetation
will be controlled. The close proximity of undisturbed native vegetation, some of which may
occur within the mine affected area, will also enhance woody plant mitigation efforts.
Planting List 1 is to be used in upland areas with northerly aspects and potentially more mesic
site conditions. These planting areas are annotated on Exhibits 22-1 and 22-1 A. The listed
species are to be planted in a mixed pattern within the areas.
Planting List 2 is designed for upland areas with more southerly aspects or tending towards
drier moisture conditions. Planting areas where List 2 species are to be used are also identified
on Exhibits 22-1 and 22-1 A. Species will be planted in a mixed pattern.
Planting List 3 is proposed for the reestablishment of aspen in selected areas. These areas are shown
• on Exhibits 22-7 and 22-1A. The planting areas are located in areas where aspen stands generally
occurred prior to mining. North facing slopes, drainages and other areas that have the opportunity for a
more mesic moisture regime have been selected as potential sites.
