چکیده

The Northern Region Landbird Monitoring Program (NRLMP) has been in place for nearly a decade. Based on our experience with this program, we offer thoughts on monitoring goals, the need for regional programs, and the components we believe make count-based monitoring effective. The NRLMP includes a biennial bird survey conducted from permanently marked points for the purposes of long-term population-trend monitoring. Its primary strength, however, emerges from the inclusion of habitat information at each survey point, which allows rapid inference about land-use effects, and from an alternate-year focus on short-term management effects studies. Those who may be planning to initiate a regional monitoring program may want to incorporate some of the perceived strengths of, and methodology associated with, the NRLMP while avoiding some of the pitfalls we have encountered. The power to detect both population trends and management effects might then emerge not only from the efforts of individual, regionally based programs but also from the collective effort of a variety of similarly designed regional programs.

Northern Region Landbird Monitoring Program: A Program Designed to Monitor More than Long-term Population Trends

The Northern Region Landbird Monitoring Program (NRLMP) has been in place for nearly a decade and is designed to allow us to track population trends of numerous landbird species, while at the same time allowing us to investigate the effects of various kinds of land use activity on the occurrence, abundance, or demographics of numerous landbird species. We conduct pointcount bird surveys biennia...

Monitoring Survival Rates Of Landbirds At Varying Spatial Scales: An Application Of The MAPS Program

Survivorship is a primary demographic parameter affecting population dynamics, and thus trends in species abundance. The Monitoring Avian Productivity and Survivorship (MAPS) program is a cooperative effort designed to monitor landbird demographic parameters. A principle goal of MAPS is to estimate annual survivorship and identify spatial patterns and temporal trends in these rates. We evaluate...

Long-term community dynamics of small landbirds with and without exposure to extensive disturbance from military training activities.

Military training activities are known to impact individual species, yet our understanding of how such activities influence animal communities is limited. In this study, we used long-term data in a case study approach to examine the extent to which the local small landbird community differed between a site in northeast Kansas that experienced intensive disturbance from military training activit...
