Section 780.18(bl Continued. <br />• suppression activities, and drought, however, woody species have been able to <br />displace herbaceous species in many areas. <br />The woody plant density values indicated by both site baseline data and as <br />summarized in the above table for existing reclaimed areas are higher than would <br />generally be the case for non-impacted areas in North Park or for either non-impacted <br />or previously impacted areas in Routt and Moffat Counties, to the west, where higher <br />precipitation favors the herbaceous component. High baseline woody plant densities <br />appear to reflect historic alteration of the ecological balance due to previous <br />disturbance and land management practices. The high woody plant densities on <br />reclaimed areas probably reflect Kerr's aggressive efforts to reestablish woody plants <br />including a high percentage of woody plant species in the reclamation seed mixture, <br />cross-seeding of woody plants, some shrub transplants, and controlled grazing to limit <br />herbaceous competition. <br />In the Kerr area, climatic, soil, and other conditions in North Park marginally favor <br />heavy herbaceous growth on reclaimed areas. Under these conditions, establishment <br />• of shrubs on reclaimed areas may be restricted by the success of herbaceous species <br />seeded during the initial stages of revegetation for erosion control, forage production, <br />and other reasons. Competitive limitations associated with the effectiveness of the <br />distributed shrub reestablishment program previously proposed and implemented for <br />the Kerr disturbance areas include both problems with establishment and re-invasion <br />of shrub species and the progressive loss of shrubs carefully nurtured from seed or <br />nursery stock due to continued vigorous herbaceous competition. <br />The revised shrub establishment approach being proposed addresses both <br />reestablishment of natural, healthy ecological relationships, with a dominant <br />herbaceous component, and problems with effective long-term shrub reestablishment <br />due to herbaceous competition. By establishing interspersed high and low density <br />shrub stands and open meadows, herbaceous competition is minimized and open <br />areas, with a dominant herbaceous component are preserved. To some extent, the <br />surface disturbance and reclamation activities associated with Kerr's mining activities <br />provide an opportunity to restore "pre-disturbance" conditions and a more healthy <br />ecological balance. <br /> <br />TR-19 780-78d Revised 12/99 <br />
