Oept of Natural Resources <br />Revegetation Success Criteria <br />(December 18. 1984) <br />In addition to the revegetation success criteria previously submitted for <br />vegetation cover and herbaceous production, the ,following criteria for <br />woody plant density and species diversity are proposed for reclamation of <br />the waste disposal area (Sutey Property) currently proposed for devel- <br />opment: <br />Woody PImit Density <br />A standard of 250 live plants per acre is proposed for those portions of <br />the reclaimed waste disposal area having slopes steeper than 2.5(h):1(v). <br />No woody plant density standard is proposed for those portions of the <br />reclaimed site less steep than 2.5(h):1(v). <br />This standard has been derived by compat' thetnearb~aspenf vegetat on <br />versus the percent cover of snowberry Y <br />type and calculating an equivalent density for snowberry based on the <br />cover of snowberry for the meadow type, all based on data fror,. the 2984 <br />• vegetation baseline inventory. In round numbers: under the aspen. <br />snowberry constitutes about eight percent of the total vegetation cover <br />and a sampled density of about 1,000 plants per acre; in the meadow type, <br />snowberry constitutes about two percent of the total vegetation cover, <br />which would be an equivalent density of 250 plants per acre. The <br />assumption is made here that there is an equivalent proportional <br />relationship in the meadow vegetation type between shrub cover and <br />. density as in the aspen vegetation type. It should be noted that only one <br />species is being compared, snowberry, which is the only significant woody <br />plant species in the meadow vegetation type. <br />Woody plant density will be measured using randomly located belt <br />transects of five meters by 15 meters, according to the method described <br />for determining woody plant density for the baseline inventory of the <br />aspen vegetation type. <br />Species Diversity <br />A standard for species diversity is proposed based on the Division's <br />diversity guideline and the vegetation baseline inventory data for cover <br />for the meadow vegetation type. The standard is as follows: <br />Based on post-mining vegetation cover data, the post-mining vegetation <br />107 <br />.~. <br />
