Point counts of birds are the most widely used quantitative method and involve an observer recording birds from a single point for a standardized time period. In response to the need for standardization of methods to monitor bird populations by census, researchers met to present data from various investigations working under a wide variety of conditions, and to examine various aspects of point count methodology. Statistical aspects of sampling and analysis were discussed and applied to the objectives of point counts. The final chapter presents these standards and their applications to point count methodology.

Point counts of buds are the most widely used quantitative method and involve an observer recording buds from a single point for a standardized time period. In response to the need for standardization of methods to monitor bird populations by census, various investigators met in Maryland in late fall 1991 to evaluate point counts. Their objectives were to present data from various investigations working under a wide variety of conditions, and to examine various aspects of point count methodology. This volume contains the papers given at the workshop, as well as a few additional relevant papers that subsequently have been submitted to the technical coordinators. Statistical aspects of sampling and analysis were discussed and applied to the objectives of point counts. From this base, at interactive sessions the participants discussed and agreed upon standards of point counts that should have wide applicability to a variety of habitats and terrain. The final chapter presents these standards and their applications to point count methodology. Forest Service, US Department of Agriculture

Monitoring Plant and Animal Populations offers an overviewof population monitoring issues that is accessible to the typicalfield biologist and land managers with a modest statisticalbackground. The text includes concrete guidelines for ecologists tofollow to design a statistically defensible monitoringprogram. User-friendly, practical guide, written in a highly readableformat. The authors provide an interdisciplinary scope to address thecurrent, widespread interest in monitoring in many environmentalfields, including pure and applied ecology, conservation biology,and wildlife management. Emphasizes the role of monitoring in adaptive management. Defines important terminology and contrasts monitoring withother data-collection activities. Covers the applicable principlesof sampling and shows how to design a monitoring project. Provides a step-by-step overview of the monitoring process,illustrated by flow charts and references. The authors also offerguidelines for analyzing and interpreting monitoring data. Illustrates the foundation of management objectives anddescribes their components, types, and development. Describes common field techniques for measuring importantattributes of animal and plant populations. Reviews different methods for recording monitoring data in thefield, managing the data, and communicating data to policymakers.
