A proposed approach for implementing a region-wide search for the ivory-billed woodpecker with the objective of estimating occupancy and related parameters


May 2007 - June 2010


The purpose of this document is to propose and facilitate a survey design for the Ivory-billed Woodpecker (Campephilus principalis) search effort that will: (1) allow estimation of occupancy, use, and detection probability for habitats at two spatial scales within its former range, (2) assess relationships between occupancy, use, and habitat characteristics at those scales, (3) allow the development of a population viability model that depends on patch occupancy instead of difficult-to-measure demographic parameters, and (4) be adaptive, allowing newly collected information to update the above models and search locations.
