Book Description
This report on avian plot methods is provided as Section 6.3.3 of the US Army Corps of Engineers Wildlife Resources Management Manual. The report is designed to assist the District or project biologist in the application of plot methods to estimate the density and diversity of bird populations for planning, management, and research purposes. Plot sampling in performed by a stationary observer who stands at each sampling point and records detections of birds in all directions during a fixed sampling period. The method is particularly suited to small or irregular study areas or where terrain is too rough for the use of transects. Plot methods can be used at any time of year. The report provides guidelines concerning plot establishment, sample size, survey timing and procedures, and interpretation of results, including and explanation and comparison of fixed plots and variable circular plots. Keywords: Avian survey and sampling, Bird populations, Plot methods, Population estimation, Variable circular plots, Wildlife management.

Book Description
Learn how to start a census program for terrestrial vertebrates with this handbook. Whether the information you need is for managing a population, surveying environmental impact, or conducting research on a particular species, this handbook has it all. Principles, methods, and calculations are explained. The following information is given for each species: name; range; reasons for census; life history; items of importance, e.g., migration; methods of census; recent and pertinent references; and comments about the various methods.
Land Condition Trend Analysis Avian Database: Ecological Guild-based Summaries
Author: Publisher: DIANE Publishing

Languages : en
Pages : 60
Book Description
Land Condition Trend Analysis (LCTA) bird database documentation capabilities often are limited to the generation of installation-wide species checklists, estimates of relative abundance, and evidence of breeding activity. The conservation and characterization of biological diversity is becoming a management objective of both governmental and private organizations, and as such, more ecologically descriptive summaries are being required. Ecological guild analyses have been proposed as a means to link wildlife to a specific biodiversity component, and thus represents an option to military trainers in evaluating impacts to wildlife communities. This report documents an LCTA database update that provides selected ecological attributes (particularly for the nesting season) for 676 bird species occurring within the continental United States. This database upgrade provides land managers the capability to: (1) generate ecological guild-based summaries with no additional fieldwork, (2) identify specific groups of birds most likely to be impacted by a spatially discrete training impact, (3) customize the local database by adjusting individual attributes for species specific to the installation, and (4) conveniently cross reference or simply convert all LCTA species codes to more globally recognized American Ornithological Union "AOU numbers" or the Bird Banding Laboratories "Alpha codes."

Book Description
Presents a compilation of methods that can be used to assay population size, demographics, & status of virtually all species of landbirds in a wide variety of habitats. Suggests priorities for selecting a monitoring method & determining station location. Presents general tasks that determine which species can be monitored, & methods of establishing & maintaining a study plot, journal keeping, & training of personnel. Describes two demographic methods & four types of censuses for determining population size & trends. Methods are suggested for measuring habitat, recording weather, & color banding. Illustrated.
