Shrub spedes will not <br />be dipped. Clipped samples will be oven-dried at 105 degrees centigrade for a minimum of 24 <br />hours and will be weighed [o the nearest tenth of a gram. Production data will be summarized <br />by computing mean production values and percent of total biomes for each dipped fraction. <br />Comparisons between the affected and comparison areas will be made using a t-test. <br />3.3 OTHER DATA <br />In addition to the cover and production data, observations will also be made on total spedes <br />diversity in each of the sampling areas. Mean number of spedes per transect will also be <br />computed. <br />3.4 MONITORING SCHEDULE <br />Field data for the monitoring studies will be collected in June or July. Vegetation monitoring <br />will continue on an annual basis for one year after surface subsidence has occurred. If the <br />hydrologic monitoring program detects any significant changes in the surface or ground water <br />regime of the study area, the monitoring program will be evaluatcd and possibly extended. <br />• <br />`J <br />ACL /nc. • P.O.
