1.3 Background and Standards for Success
<br />Information regarding dates of reclamation earthwork activities and seeding dates are provided in
<br />other supporting documents. The following Big Sagebrush Shrubland seed mixture was implemented on
<br />all Munger Canyon Mine reclaimed areas.
<br />The bond release success criteria for the Phase III Release Block of the Munger Canyon Mine are
<br />derived from vegetation cover and herbaceous production comparisons to the Sagebrush Reference Area
<br />(established in 1980) in addition to an independent woody plant density standard. Noxious weed cover
<br />may not count towards vegetation success criteria. Noxious weed determination is based on the current
<br />Colorado state noxious weed list.
