Perennial grasses dominated the seeded vegetation on this site contributing a total of 52.62
percent of the total plant cover. Western Wheatgrass, Intermediate Wheatgrass, Blue Grama and
Sideoats Grama were the most commonly encountered grasses, contributing 27.58, 10,49, 4.70
and 3.35 percent, respectively, of the total relative cover found on this site. Cicer Milkvetch was
the most commonly encountered perennial forb on this site, contributing 18.72 percent of the
total relative cover.
The locations of the 30 cover transects sampled on this site are shown on Map 1, Raton Creek
Mine - 2004 Vegetation Transect Location Map. Copies of the individual field data sheets for
the plant cover sampling of this site are found in Exhibit A - Copies of Raton Creek Mine - 2004
- Plant Cover Field Data Sheets. The sample adequacy calculations in Table 2, Raton Creek Mine
Sample Adequacy Calculations, document that the number of samples required to describe this
site at the 90 percent confidence interval was determined to equa127.3 cover transects,.
Production. The results of the 68 production transects sampled at the Raton Creek Mine are
summarized in Table 4, Raton Creek Mine - 2004 -Production. The average forage production
on this site averaged 33.78 g/1/4mZ or 1,203.9 pounds of air dry forage per acre. Perennial
grasses contributed 24.52 g/1/4mZ or 72.59 percent and perennial forbs, contributed 9.26 g/1/4mZ
or 27.41 percent of the forage production on this area. The revegetation forage production
success standard for the Raton Creek Mine is 300 pounds of air dry forage per acre. Since this
site averaged 1,203.9 pounds of air dry forage per acre, it can be concluded that this azea satisfies
the revegetation success standard with respect to forage production.
The locations of the 68 production transects sampled on this site aze shown on Map 1, Raton
Creek Mine - 2004 Vegetation Transect Location Map. Copies of the individual field data sheets
for the forage production sampling of this site are found in Exhibit B -Copies of the Raton Creek
Mine - 2004 -Production Field Data Sheets. The sample adequacy calculations in Table 2, Raton
Creek Mine Sample Adequacy Calculations, documents that the number of production transects
required to characterize this site at the 90 percent confidence interval was 52.3. Since the
reclaimed area production at the Raton Creek Mine (1,203.9 pounds} exceeds the revegetation
success standard (300 pounds per acre,) it can be concluded that the permanent reclaimed areas
on the Raton Creek Mine satisfy the forage production revegetation success standazd.
Shrub Density. The shrub density counts obtained from the 250 belt transects sampled on the
Raton Creek Mine are summarized in Table 5, Raton Creek Mine - 2004 -Shrub Density. The
average shrub density was determined to equal 5.65 shrub stems per one hundred square meters
or 228.6 shrub stems per acre. Rubber Rabbitbrush, Fourwing Saltbush and Winterfat were the
most commonly encountered shrubs. The revegetation shrub density success standard for this
area is 500 stems per acre. Since this site averaged only 228.6 stems per acre, it can be concluded
that the reclaimed aeeas on the Raton Creek Mine do not satisfy the Permitted revegetation
success standazd with respect to shrub density. Additional discussion on this matter is found in
the Conclusions and Recommendation Section which follows.
