Quantitative Tools for the Monitoring of Threatened Species: A Marbled Murrelet Case Study (in Proc. Conference Biology & Management of Species and Habitats at Risk) Boulanger, John G.

Abstract: Recent developments in quantitative methods can potentially improve the statistical rigor of monitoring programs. Matrix modelling and power analysis are valuable tools in the design of monitoring programs even for species in which sparse data exist. Newer distance and mark-recapture methods can improve the quality of estimates when compared with count-based methods. This paper presents a case study of the marbled murrelet (Brachyramphus marmoratus) to illustrate the application of these methods. Two possible murrelet life history scenarios that represent the extremes of plausible murrelet parameter values, given the limitations of current knowledge, are examined to illustrate matrix modelling and power analysis. Sensitivity analysis suggests that regardless of life history scenario, murrelet populations are more sensitive to changes in adult survival, and less sensitive to juvenile survival and productivity...
