I've worked on several large surveys, often in conjunction with John Guidice, the MNDNR's survey biometrician. Together, we've explored cost-precision tradeoffs involved in choosing a plot size in aerial surveys [2]. I've also worked with collaborators at Carleton College, to develop methods for modeling detection probabilities in conjunction with snow track surveys [3]. Recently, much of my time has been spent working with sightability models, including the development of a software package for program R [4]. We've applied these methods to moose in MN and mountain goats in Washington State [4-5]. In addition, we've discussed strategies for handling model uncertainty when building sightabilty models [5] and also the importance of accounting for correlation among stratum specific estimates [1]. In addition, we've recently developed a Bayesian model-based alternative that offers significant advantages when estimating trends from multi-year surveys [7, 8]. Lastly, I've worked with colleagues at the National Marine Fisheries Service to develop approaches to estimating fish abudance from underwater camera surveys [9], and I led a project aimed at developing cost-effective methods for surveying zebra mussels in newly infected lakes [10].
