Detecting Population Declines over Large Areas with Presence-Absence, Time-to-Encounter, and Count Survey Methods

Article Abstract:

Studies using the Northern flicker show that count surveys would be the most cost-effective method for detecting population declines but would necessitate a reduction in the number of sites surveyed. If reducing the number of sites is undesirable, a presence-absence survey then becomes the most cost-effective method.

Avoiding pitfalls of using species distribution models in conservation planning

Article Abstract:

The article evaluates five different nature conservation models, applied to 11 Brazilian forest bird species. Models were found to differ significantly in reserve network flexibility and scope, indicating caution should be used to prevent overestimation of species occurrences.

Increasing the Accuracy of Productivity and Survival Estimates in Assessing Landbird Population Status

Article Abstract:

Methods recommended for land bird conservation include gathering data on juvenile overwintering and postfledging survival, calculation of individual season-long productivity, and including adult breeding dispersal into yearly survival estimates.
