4.0 METHODS <br />The methods used for data collection in 1996 and 1997 conformed to the <br />procedures outlined in the 1995 CDMG Bond Release Guideline and the sampling plans <br />and revisions approved by the CDMG. Revisions were made to the sample allocation <br />method between the 1996 and 1997 field studies at the direction of the CDMG. in <br />concert with these changes, the data collected in 1996 was reevaluated as part of this <br />report to allow for more direct comparison of results. <br />4.1 Same Site Location <br />All sample sites within the reclaimed study area and reference azeas were randomly <br />located. Sites on the study azea and reference areas were chosen with numbers from a <br />random number's table by plotting these figures on a map of the area using a grid system <br />laid out on that map. Once the sample sites were located in the field, cover and shrub <br />transects were run in random compass directions. <br />1996 Stu <br />Sample sites on the reclamation were selected using a stratified random sampling <br />scheme based on the year of seeding and the acreages seeded within each yeaz. This <br />method is termed proportional allocation and was modified as approved for this study. In <br />proportional allocation, at least one sample observation is randomly located within each <br />yeaz of seeding, with the number of observations allocated to any particular year of <br />seeding proportional to the percentage of the total bond release acreage contributed by <br />that year of seeding. Topsoil Pile B, Topsoil Pile C, the Sanitary Landfill site, and the <br />Explosives Storage site were included in this sampling scheme as separate units so at least <br />3 <br />
