In order to <br />meet the requirements for establishing a diverse vegetation on the reclaimed <br />surface, the Division must set success criteria for veyetative diversity. <br />A11 coal operations arc required to submit baseline vegetation data, if avail- <br />able. Operators are required to provide Laseline cover or productivity data <br />by species. When this baseline information is ava.ilablc the Di vi :;ion will use <br />the baseline information to establis:r success criteria for species diversity. <br />Diversity success criteria will reflect the nature of the premininy communitu <br />or communities at the mine site. <br />Zn some instances, operators have not been able to obtain baseline veyetation <br />information. For these cases, the Division w.i11 set the following success <br />criteria. In order to demonstrate that the species diversity and seasonal <br />variety of the reclaimed area meets the req ui renu.nts of Ru1c •1.15.8 the <br />following criteria must be taken into considervtion. <br />a. Maximum domi Hance (rcla ti ve importance) of any one species <br />b. rtlinimum number of species on reclaimed areas <br />c. Post-mine land-use utility <br />- life-form representation <br />- canununity diversity <br />lerbaceous species diversit <br />a. Using relative cover or production values for each species, the <br />reclaimed areas should have at least 5 perennial species with relative <br />importance equal to or greater than 3"6, but with all 5 c:pecies combined <br />not to exceed 75o in relative importance anr/ with an~JOr:e of these 5 <br />species not to exceed d0"6 .in relative i.mportancn. <br />b. Based on mina-sprcific si CC con d.i tir, n:; .rod La wl-u::c ol, jcc C,i v.::, Ji.re <br />form requirements with respect to herbaceous plants may be imposed (i.e. <br />at least 1, 2 etc. of the 5 herbaceous species should be a r.•ar.m season <br />grass, a cool season grass, a forb, r.tc.) <br />Shrub diversity (when applicable) <br />a. Using density values for each species on rangeland/wildlife habitat, <br />the reclaimed areas should have no shrub (o r. troc) species whose mlati ve <br />importance exceeds 60"~ (80"6 if only 2 shrub .pecicc arc to ho planted). <br />A23 COnicnni7l ©uildinfl 1313 Shr•nnnn FU not Drnvri.
