• Section 4.6 provides details on methods. Such transplants will have the added benefit of using
native species and genotypes of plants for revegetation. This will be a valuable source of
difficult to obtain native species.
Tables 3.6-7, 3.6-8, and 3.6-9 list the preferred species for reestablishing on each range site
occurring within the proposed mine permit area. The proposed species mixes favor grasses
and (orbs. At a minimum, 14 herbaceous plant species will be seeded and/or transplanted
within each range site to be revegetated. The total number of genera and species to be
reseeded are based generally on the dominant species determined by the diversity index for
each range site (Section 2.3). A comparison of the species mixes in Tables 3.6-7, 3.6-8 and 3.6-9,
and the diversity Tables 2.3-15 through 2.3-20 will show that Trapper Mine species mixes are
more diverse than what existed prior to mining. Such an approach is necessary since one may
not predict precisely how reseeded species on reclaimed mined land will react over time. By
March 15 of each year, the Division will be provided with the proposed species list to be
seeded that year according to range site or area of use. This is necessary since seed
availability on a year -by -year basis varies.
Not less than 30 PLS per square foot will be seeded if drilled or 45 PLS per square foot if
broadcast seeded.
• Range Site B
For revegetation purposes, range site B is mountain shrub type below 7200 feet and above 6700
feet in elevation. The species mix for this range site is presented in Table 3.6-7. During the
permit period, select species continued in Table 3.6-7 will be seeded and/or transplanted within
the described approximate elevation range. Generally, all seeding will be accomplished in the
fall of the year. Spring seeding may be used for drainageways, cropland areas and transplants
may be planted fall through spring.
Introduced species found in the species mix for range site B are fairway crested wheatgrass,
Agropyron cristatum; pubescent wheatgrass, A. trichophorum;
