【 摘 要 】

Annual monitoring in support of the Fluor Daniel Hanford Company (Fluor) Mitigation Action Plan (MAP) for Project L-325, Electrical Utility Upgrades was conducted in June 2009. MAP guidelines defined mitigation success for this project as 3000 established sagebrush transplants on a 4.5 ha mitigation site after five monitoring years. Annual monitoring results suggest that an estimated 2130 sagebrush transplants currently grow on the site. Additional activities in support of this project included gathering sagebrush seed and securing a local grower to produce between 2250 and 2500 10-in3 tublings for outplanting during the early winter months of FY2010. If the minimum number of seedlings grown for this planting meets quality specifications, and planting conditions are favorable, conservative survival estimates indicate the habitat mitigation goals outlined in the MAP will be met in FY2014.
