05/21/98 16:21 $9169792770 FISH & WILDLIFE Z009 Plant Associated Native Species Studies have found that the beetle is more abundant in dense native plant communities with a mature overstory and a mixed understory. Therefore, a mix of native plants associated with the elderberry shrubs at the project site or similar sites will be planted at a ratio of at least one(1)specimen of native tree and shrub species for every elderberry plant(seedling or cutting). These native plantings must be monitored with the same survival criteria used for the elderberry seedlings(see below). Stock of saplings,cuttings, and seedlings should be obtained from local sources. If the parent stock is from more than one mile from the mitigation site,approval by the Service of the native plant donor sites will be obtained prior to initiation of the revegetation work. Planting or seeding the mitigation area with native herbaceous species is encouraged. Establishing native grasses and forbs may discourage unwanted non-native species from becoming established or persisting at the mitigation site. Only stock from local sources should be used. Example 1 A total of 5 elderberry shrubs with at least one stem measuring 1.0 inch or greater in diameter at ground level will be effected by the proposed action. The 5 shrubs have a total of 23 stems measuring over 1.0 inch. Exit holes were observed in 2 of the 5 shrubs(3:1 compensation ratio required). The mitigation site is suited for riparian forest habitat. Associated natives adjacent to the mitigation site are box elder(Acer negundo californica),walnut(Juglans californica var. hindsii), sycamore(Platanus racemosa),cottonwood(Populus firemontdf),willow(Salix gooddingii and.S. laevigata), ash(Fraxinus latifolia),button willow(Cephalanthus occidentalis), and wild grape(Mitis californica). Compensation: •Transplant the 5 elderberry shrubs that will be effected to the mitigation site. -Plant 69 elderberry rooted cuttings (3:1 ratio,cuttings planted:stems effected) •Plant associated native species: 9 saplings each of box elder,sycamore,and cottonwood 20 willow seedlings 5 saplings each of walnut and ash 8 California button willow" 4 wild grape vines •Total area required is a minimum of 1,800 sq.ft.for every 5 elderberryseedlings =24,840 square feet=0.57 acre Example 2 A total of 6 elderberry shrubs with at least one stem measuring 1.0 inch or greater in diameter at ground level will be effected by the proposed action. The 6 shrubs have a total of 20 stems measuring over 1:0 inch. Exit holes were observed in 4 of the 6 shrubs(5:1 compensation ratio required). The mitigation site is suited for elderberry savanna or mixed riparian forest. Associated natives adjacent to the mitigation site are willow(Salix species),cottonwood(Populus fremontit), ash(Fraxinus latifolia),sycamore(Platanus racemosa),poison oak(Toxicodendron diversilobum), and wild grape(Mis californtca). Compensation: •Transplant the 6 elderberry shrubs that will be effected to the mitigation site. •Plant 100 elderberry seedlings(5:1 ratio,seedlings planted:stems effected) - Plant associated native species: 10 saplings each.of ash,cottonwood, and sycamore 5
