-23- XII. YVegetation - Rules 2.04.10, 2.05.4(2)(e), and 4.15 (con's)- •- In the sampling program undertaken, inadequate numbers of samples were taken to provide the current desired levels of confidence {p2 .BO for non- herbaceous communities, d = .10, ~c (2)), for the productivity of the greasewood shrubland, shadscale shrubland, and juniper woodland vegetation types. The Munger Canyon project contains the same vegetation types and is located contiguously to the PtcClane Canyon site. Abiotic factors affecting the occurrence of vegetation communities are similar. For this reason, data from the two sites for productivity of the above communities were compared to determine i£ the communities of PicClane and Munger Canyon were from differing populations. It vas verified statistically that the McClane and Munger respective communities were not significantly different is terms of vegetative productivity within the bounds of each vegetative community. Data from the McClane and Plunger sites were combined (within communities,. between sites), and it was determined that the combined data met confidence level requirements. Due to the small aiea of disturbance at the PicClane site, the Division has _ determined that premine productivity and premine cover data may be applied as reclamation success criteria. It was also determined that the productivity .. data for the reference areas for the PlcClane Canyon vegetative communities did not meet sample adequacy requirements. The following stipulation is - - therefore required: __ ~,~~== 9. IN LIEU OF PRODUCTIVITY DATA FR0:1 THE GREASEWOOD SHRUBLAND, SHADSCALE SfIRLBLAND, AND JUNIPER WOODLAND REFERE`iCE AREAS, THE PER*fITTEE ZS -_- DIRECTED TO UTILIZE COMBINED McCLANE AND PRTNGER PREPiINE DATA FOR i ""'- PRODUCTIVITY FOR EACH VEGETATIVE CO`,31UNITY RESPECTIVELY. THIS DATA -~ _ SHALL BE SUBJECT TO THE R$VEGETATION SUCCESS CRIZERIA OF 4.15.8(3)(b). ~~_ aP ~'~ The applicant has not demonstrated that adequate woody plant density sampling', -= has taken place at the 2fcClane Canyon site.

The Division has reviewed the PScClane Canyon revegetation plan and revegetation criteria (Sections 3.4 and 4.5.12 of Volume I of the application). The applicant has proposed a variance from baseline woody plant densities for - -. the greasewood shrubland and the shadscale shrubland, but has not provided - justification for the proposed stocking level. IC is therefore stipulated: 11. THE PEAPfITTEE PNST PROVIDE JUSTIFICATION TO THE DIVISION FOR THE WOODY PLA;7T DENSITY REVEGETATION LEVELS PROPOSED.
