In a recent paper (Ecological Impacts, Vol. 39, pp. 94-101), Carrie Levine and colleagues describe methods for analyzing long-term monitoring data to evaluate whether current monitoring programs are as efficient and effective as possible. This can allow researchers to maximize information gained relative to resources required for data collection. In the paper, the authors describe methods for analyzing data from four types of monitoring schemes: long-term records from a single site, one-time surveys at multiple sites, plot-level sampling, and time-series data from multiple sites. Evaluating long-term monitoring data at regular intervals throughout the monitoring program can help researchers determine whether sampling should be reallocated in space or time to optimize the use of financial and human resources.
