Surveys for streaked horned lark in Washington have not been conducted in a standardized manner across sites and years. Most data have been collected as part of research efforts looking at population vital rates and habitat selection. Pearson et al. (2008) recommended developing a comprehensive monitoring scheme to examine range wide population trends that could also be used to evaluate the effectiveness of management actions. In response to this need, a draft survey protocol was developed in 2010 and applied across most of Washington’s occupied sites in 2010 and 2011. This report summarizes the results of the 2011 surveys and makes some initial comparisons with data collected in 2010. Additional analyses should be conducted on these data to determine their usefulness in tracking population trends.
