The data collected, as well as our observations in the field, indicate that, as expected, no <br />adverse conditions can be attributed to not mulching. Vegetation has established as expected <br />and there is no evidence of erosion directly attributed to the lack of mulch. <br />The techniques currently utilized by Colowyo to control erosion on these unmulched slopes <br />will continue to be implemented. It is generally recognized that it is the chiseling, contour <br />furrows and drainage benches that contribute to erosion control rather than the mulch. It is <br />generally accepted by the local mines in the region that early mulching was completed <br />because of a regulatory requirement rather than any ecological benefit towards successful <br />reclamation. <br />Colowyo recognizes that initial vegetation establishment will continually be monitored <br />through the "monitoring plan" and field inspection by both the Division and Colowyo <br />personnel will continue. If it appears that the suspension of the mulching requirement is <br />detrimental to vegetation establishment or contributes to excessive erosion, mulching will be <br />resumed. <br />Irrigation <br />No irrigation is planned for areas to be seeded or mulched. Possible watering of transplanted <br />shrubs or seedlings, with supplemental applications during the first two growing seasons, will <br />be the only water used during revegetation. Colowyo watering trucks used for dust control <br />will be used for the supplemental watering. <br />• Pest and Disease Control <br />Noxious plants, as defined in Section 1.04, will be controlled using the recommended <br />methodologies of the Colorado State University Extension Service. If insects become a <br />problem to the point where they endanger the successful establishment of the seeded <br />vegetation on the reclaimed area, they will also be controlled using methods suggested by the <br />Colorado State University Extension <br />u <br />2.05-56 <br />
