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. The main objectives of this project are to collect streaked horned lark data that can: detect changes in abundance of adults at occupied sites. A follow-on objective is to use these data to develop an efficient and effective statewide monitoring scheme that can account for differences in detectability between sites, observers, survey periods and environmental conditions in order to increase precision and minimize variance surrounding abundance estimates.
