<br />With the help of the CMRF, an undetermined volume of soil has been accumulated at this site. <br />Most of this soil came from new projects at Cedar Heights. This soil is similaz to the soil that was used <br />on the visual berm although the quality appears to be slightly lower because of differences in the soil <br />quality at the source sites. Nevertheless, experience has shown that soil from Cedar Heights, because it <br />comes from a vegetation and soil development regime similaz to the quarry, provides an excellent <br />growth medium at this quarry. The soil not only is "pre-adapted" to the conditions but contains a <br />prodigious seed bank of native herbaceous and woody species. This seed bank is the very reason why <br />no shrub planting is needed on the visual berm. The density and growth quality of the native shrubs <br />on the visual berm, which aze derived from the seed bank in the original soil, far exceeds anything that <br />could reasonably be produced by human directed planting, even using the same species. The visual <br />berm at this site is one of the best examples of what can happen when soils, microenvironmental <br />conditions, timing, and all other aspects of revegetation aze near ideal. The result is a rapid return to a <br />highly natural type of growth. In retrospect, it is unfortunate this berm was planted with Russian <br />Olive as it definitely detracts from the naturalness of the herbaceous and native woody vegetation. On <br />the other hand, the Russian Olive has certainly aided in binding the soil and the underlying limestone <br />fines. Although the appeazance of the berm may be found to be somewhat undesirable by some <br />viewers, ecologically the vegetation on this area is extremely diverse, stable, and shows signs of a <br />continuing highly structured developmental pathway. <br />It is expected that mining during the next year will primarily concentrate on the West Ridge. <br />Thus expansion of the existing affecced land is not expected in the next year. <br />Following is an inventory of the acreage of various features shown on the map. Note that <br />some of the acreages have changed slightly from what was reported previously. This is because of a <br />new approach to measuring the azea in the category and not because it actually changed. Altered <br />figures derived from this new method are marked with an asterisk. <br />Map Category Acreage <br />Visual Berm 2.5 <br />Phase 1 Reclamation 6.4* <br />West Ridge Preparations 4.2 <br />Total Affected Land 65.6* <br />(plus road corridor not on map) <br />Violation Reclamation 0.4 <br />Annual Report Snyder Quarry 96/97 M-77-210 Page 2 <br />
