United States Department of the Interior NATIONAL PARK SERVICE Grand Canyon National Park P.O. Box 129 Grand Canyon, Arizona 86023-0129 F54 (GRCA 8213) Ms. Evelyn Erlandsen Arizona Water Protection Fund 3550 N. Central Avenue Phoenix, AZ 85012 Dear Ms. Erlandsen: Enclosed please find the revised and final October 31, 2008 deliverable for the project entitled “Management & Control of Tamarisk and Other Invasive Vegetation at Backcountry Seeps, Springs and Tributaries in Grand Canyon National Park (Second Year of Phase II of Comprehensive Project)”, Arizona Water Protection Fund (AWPF) Grant Number 06-138WPF. The deliverable falls under Task # 5 in the contract and is the final report for all of the work completed during this contract period. The funding that the Arizona Water Protection Fund has provided has allowed the park’s Backcountry Vegetation Program staff to accomplish critical preservation and restoration work in the park’s backcountry areas. With issues like invasive species, it is essential to disregard boundaries, and this project has provided the opportunity to work directly with the Hualapai Tribe and look at the greater Grand Canyon area as a whole, rather than segmented parts. I appreciate the support that you have provided as the project manager. Please consider this the final version of the report, one professionally bound, and one copy of just the report body itself to merge with the appendices you already have. I mailed two copies of the poster-size map separately. If you have any questions about the revised and final report, please contact me at (928)226-0165. Sincerely, Lori J. Makarick Vegetation Program Manager Enclosures (2) Grand Canyon National Park and Grand Canyon National Park Foundation Final 2008 Management and Monitoring Report Management & Control of Tamarisk and Other Invasive Vegetation at Backcountry Seeps, Springs and Tributaries in Grand Canyon National Park (Phase II-B, First Year of Phase II of Comprehensive Project) Arizona Water Protection Fund Contract Number 06-138WPF October 24. 2008 Revised and Re-Submitted December 9, 2008 Prepared by: Lori Makarick Vegetation Program Manager Grand Canyon National Park 823 North San Francisco, Suite B Flagstaff, AZ 86001-3265 Phone: (928) 226-0165 Email: [email protected] I.
