• Total cost for areas receiving this treatment is approximately $4500. Revegetation activities will be completed concurrent with project phases. Areas B2, A9, and E3 will be completed with Phase 1, Area E5 will be completed with Phase II, and Areas Al l . and A6 will be completed with Phase III. Management activities associated with the establishment of the communities will be completed within approximately 3 years of the seeding date. The long -term viability of these areas is expected to be good, with low to moderate on= going maintenance requirements. C. Existing. Wooded Areas — Invasive Shrub Removal and Management. Wooded areas throughout the property have been subject to historic disturbance.by livestock. As a result, invasive shrubs have become a dominant component of the understory, competing with more desirable native species and shading herbaceous ground cover. Management of these shrubs generally involves shrub removal and direct herbicide application.to prevent regrowth. A second treatment may be required after 1 -2 years, with a light burn, as feasible. • This.treatment is appropriate for areas A10, Bl, B4, Cl, C3; C4, and El. Appro/dinately. 7.5-acres are proposed for this treatment. _ Costs for.this treatment are expected to range from $2,500. _ $5,000 per acre. Total cost for areas receiving this treatment is $ 19,000 — $37,500. •Shrub.ren3oval will begin during April and May, 2000, and be completed by October, '2001. • The long -term-viability of this approach is uncertain. Without ongoing control activities. these, areas are likely to be re- invaded due to the abundance in seed sources on adjacent • properties. D. Wetlatnd Vegetation Restoration Wetland E3 (Wetland E) currently is dominated by a reed canary grass monoculture, which has Iow aesthetic and wildlife habitat values. Proposed: activities would include removal of the existing plant community by. chemical treatment and scraping, if appropriate, the upper 12 inches- of soil. The area would then be reseeded with a suitable wet meadow mixture. • • Estimated cost to complete the restoration of this 0.5 -acre wetland is $3000.
