摘要

During 2002, field studies of the endangered Hawaiian monk seal (Monachus schauinslandi) were conducted at all of its main reproductive sites in the Northwestern Hawaiian Islands. These studies provide information necessary to identify and mitigate factors impeding the species recovery by evaluating (1) the status and trends of monk seal subpopulations; (2) natural history traits such as survival, reproduction, growth, behavior, and feeding habits; and (3) the success of various activities designed to facilitate population growth. Results of these studies are best described on a site-by-site basis, and the information presented in this document is organized accordingly. Site-specific data pooled for all sites, however, provide useful indices of the status and trends of the species as a whole, including the total number of pups at all main reproductive sites, the total of the site-specific mean beach counts, and the size composition of the seals observed during the counts.
