• During the course of the fieldwork, a list of all plant species encountered (quantitative plus <br />incidental observations) was compiled for each reclamation area and the three reference areas. <br />These lists are summarized in Appendix 2, Species Presence for All Areas, which includes <br />current nomenclature and cross-references to older nomenclature. Note that all big sagebrush <br />plants encountered were referred to as Seriphidium tridentatum. Plants referred to here as Poa <br />secunda are the plants formerly known as big bluegrass (Poa ampla) that were included in the <br />seed mixes as such. The taxonomic treatment of Weber and Wittmann (1996) places Poa ampla <br />(as well as Poa sandtrergir~ with Poa secunda. Despite this merger, the distinctness of Poa <br />ampla is worth noting. <br />Photographic Record <br />Within each reclamation and reference area, representative color photographs were taken to <br />document the appearance of the vegetation in 2006 (Appendix 4). Within each reclaimed area <br />photograph, a placard identifies the particular area and sample. <br />Statistical Methods <br />Sampling was conducted at randomly located sites. Random map points for sampling locations <br />were generated using a random point generating script in ESRI ArcView 9.2 software. These <br />• sample points were located in the field using topographic maps. Cover and woody plant density <br />transects were randomly oriented; production samples were located randomly behind the transect <br />origin. At each cover/woody plant density sampling location, the slope, expressed as a percent, <br />and aspect of the site, in degrees not corrected for magnetic declination, were determined and <br />recorded, as was the orientation of the transect. <br />Assessment of Reclamation Adequacy <br />GENERAL <br />Formal (statistical) hypothesis testing (see below) was undertaken for BRB-3 (post-law, <br />Permanent program lands). For lands reclaimed from February 25, 1976 to September 23, 1981, <br />and subject to provisions of Interim (initial) program and the similar 1976 Colorado Act (BRB-2), <br />quantitative cover and production data were used as a basis for discussion. <br />SAMPLE ADEQUACY DETERMINATION <br />After fifteen (15) cover samples in a BRB or reference area, sample adequacy was evaluated <br />based on total live foliar cover by vascular plants using the following expression: <br />I • 5 <br />
