However,in this case the habitat will be restored to elderberry savanna and more space is needed. A total of 1.4 acres(approximated 3,000 sq. ft. for every 5 elderberry seedlings) is proposed. Fewer associated native trees and shrubs than required are proposed for planting,but the mitigation site will be seeded and planted with native grasses and forbs, and closely monitored and maintained throughout the monitoring period. Mitigation Area—Provide Habitat for the Beetle in Perpetuity The mitigation area is distinct from the avoidance area(though the two may adjoin),and serves to receive and protect the transplanted elderberry shrubs and the elderberry and other native plantings. The Service may accept proposals for off-site mitigation areas where appropriate. 1. Size. The mitigation area should provide at least 1,800 square feet for each transplanted elderberry shrub. As many as five(5)elderberry cuttings or seedlings and up to five(5) associated natives may be,planted within the 1800 square foot area with each transplanted elderberry. An additional 1,800 square feet shall be provided for every additional five(5) elderberry cuttings or seedlings and five(5)associated natives planted Each planting should have its own watering basin measuring approximately three(3)feet in diameter. Watering basins should be constructed with a continuous berm measuring approximately eight(8)inches wide at the base and six(6)inches high. The pIa_nting density specified above is primarily for riparian forest habitats or other habitats with naturally dense cover. If the mitigation site is an open habitat (i.e.,elderberry savanna,oak woodland)more area may be needed for the required plantings. Contact the Service for assistance if the above planting recommendations are not appropriate for the proposed mitigation site. No area to be maintained asa firebreak may be counted as mitigation area. Like the avoidance area; the mitigation area should connect with adjacent habitat wherever possible,to prevent isolation of beetle populations. 2. Long-Term Protection. The mitigation area should be protected in perpetuity as habitat for the valley elderberry longhorn beetle. Fee title,a conservation easement or similar agreement,or deed restrictions to protect the mitigation area should be arranged. Mitigation areas should be transferred to a resource agency or appropriate private organization for long-term management. The Service should be provided with a map and written details identifying the mitigation area; and the applicant should receive approval from the Service that the mitigation area is acceptable prior to initiating the mitigation program. A copy of the deed transfer,conservation easement,or deed restrictions protecting the mitigation area in perpetuity should lie provided to the Service before,or concurrent with,the submission of the final monitoring report(see below). 3. Weed Contrgl. Weeds and other plants that are not native to the mitigation area should be removed at least once a year,or at the discretion of the Service and the California Department of Fish and Game. Mechanical means should be used;herbicides are prohibited. 4. Pesticide and Toxicant Control: Measures should betaken to insure that no pesticides, 6
