The seed mixture to be planted is shown in Section 2.05 <br />on Table 7, Reclamation Seed Mixture. <br />The details of the revegetation plan are discussed in Section 2.05.4. <br />4.15.1(4) Vegetation Monitoring <br />The monitoring plan to evaluate the success of shrub plantings, mature <br />transplants, natural reinvasion by sagebrush, as well as initial <br />herbaceous vegetation success is as follows: <br />1. To facilitate identification, sampling of herbaceous vegetation will <br />take place during the peak of the growing season when the vegetation <br />reaches the mature stages. This period of time is generally from <br />late June to early August. <br />Unlike sampling for bond release purposes, sampling will not be <br />required to meet statistical adequacy. <br />2. During the first growing season of a reseeded area, a frequency <br />determination by genera of seeded and volunteer species will be <br />performed. From this information, the apparent density value can <br />be determined for the seeded species, and unsatisfactory stands of <br />any component can be identified for corrective action. <br />3. During the second and fourth growing season of a reseeded area, <br />herbaceous cover and woody plant density information will be <br />gathered. This information will be gathered at the species level <br />and will reflect the effectiveness of the seed mixture, volunteer <br />shrubs, planted and transplanted shrubs on establishing themselves. <br />4. The data and an assessment of the monitoring results will _be <br />submitted in the Annual Reclamation Report. A map will be included <br />to delineate the reclaimed areas being sampled each year. The Annual <br />Reclamation Report will also provide details regarding restricted <br />interseeding or other mitigative measures implemented as a result <br />of the vegetative monitoring program. <br />Revision Submitted <br />S- ie-9 i <br />Revision No. T R - 4 ~ <br />4.15-1 <br />
