Environmental Impact Research Program: Snowy Plover (Charadrius alexandrinus). Section 4.4.1. US Army Corps of Engineers Wildlife Resources Management Manual

摘要

A wildlife species account for the snowy plover (Charadrius alexandrinus) is provided as Section 4.4.1 of the US Army Corps of Engineers Wildlife Resources Management Manual. The account is developed as a guide to provide the Corps District or project biologist with basic information on the biology, ecology, and management of the snowy plover. Major topics covered include status, characters and measurements, population attributes, habitat requirements, management, and census and sampling. The geographic range of the snowy plover is described, and the status of the species in North America is discussed. Diagnostic features and criteria for sex and age determination are given under the heading characters and measurements. The section on population attributes provides information on abundance, movements, movements, breeding biology, and mortality. Ecological requirements are discussed, and components of breeding habitat are described for the West Coast and interior sites. Strategies for managing snowy plover habitat and controlling degradation of breeding sites are presented. The census and sampling section provides techniques for measuring habitat variables and estimating plover populations.
