McLeod M and Koronkiewicz TJ. 2009. Southwestern willow flycatcher surveys, demography, and ecology along the lower Colorado River and tributaries, 2008 annual report. Contract number GS-10F-0209L. SWCA Environmental Consultants. Flagstaff, AZ
Reclamation initiated willow flycatcher studies along the lower Colorado River in 1996, in anticipation of the requirements outlined in the BOs that were part of LCR MSCP development. These studies have been conducted annually since 1996. In compliance with the consultation on Interim Surplus Criteria and Secretarial Implementation Agreements, Reclamation biologists deployed temperature/humidity data loggers in 2004 at a subset of sites currently monitored for Southwestern Willow Flycatcher along the Colorado River in California and Arizona. These studies were expanded in 2005 to include annual monitoring of groundwater levels, vegetation, and soil moisture in addition to temperature and humidity.
