This technical report summarizes a regional workshop on monitoring programs for the Interior Least Tern ILT Sternula antillarum in Tulsa, Oklahoma in November, 2005. Discussions focused on 1 defining goals and objectives for local, regional, and range-wide monitoring programs 2 deciding what information to collect during monitoring programs 3 standardizing data collection and analysis protocols among programs 4 integrating local efforts into regional or rangewide approaches and 5 evaluating the effects of management actions on ILT within the context of regional or range-wide recovery. This summary reviews existing monitoring programs and suggests a course of action for developing a range-wide monitoring plan to better evaluate the effects of management on ILT. Consensus was that annual range-wide counts of adults during a standard survey window would be advisable to track longterm changes in ILT population trends and distribution. Participants agreed that data on reproductive success and how this relates to management are also necessary to evaluate population health. However, many participants were concerned that estimates of fledglings per pair for Least Terns may be highly inaccurate. Participants agreed on ways to pursue monitoring of nest success and nest fates as indices to reproductive performance that could be analyzed versus factors associated with management issues e.g., flooding on dam controlled rivers, recreation impacts. Two monitoring committees were formed to advise the ILT Working Group in this process.
