PROTECTED AREAS OF WESTERN MEXICO: STATUS, MANAGEMENT, AND NEEDS Edited by Charles S. Aid Michael F. Carter Colorado Bird Observatory A. Townsend Peterson Natural History Museum, University of Kansas A PROJECT OF COLORADO BIRD OBSERVATORY September 1, 1997 1 PROLOGUE The Colorado Bird Observatory (CBO) was founded in 1988 to address the conservation needs of birds in the Rocky Mountains and Great Plains. CBO has employed a broad spectrum of tactics toward this end, including intensive study of endangered species; habitat assessments for the birds of endangered ecosystems; monitoring of population status of Colorado's breeding avifauna; and setting conservation, management, and monitoring priorities for breeding Neotropical migratory birds for all 50 U.S. states. In addition to a strong research program, CBO has implemented programs aimed at improving environmental education in both Mexico and the United States. Given that many of Colorado’s birds are Neotropical migrants, many of CBO's activities have focused on determining habitat requirements, population status, and conservation priorities for these species. Recognizing the critical dependency of Neotropical migrants on adequate wintering habitats, as well as the needs of the many species of birds resident in Mexico, many of which occur nowhere else, CBO began work in western Mexico in the winter of 1991B1992, focusing on the five Pacific coastal states of Jalisco, Colima, Michoacán, Guerrero, and Oaxaca. From these initial explorations, in an effort to contribute to the efficacy of conservation efforts in the region, the present effort was born C a summary and analysis of the status and needs of western Mexico's protected natural areas. Principal objectives of this effort are the following: (1) To compile a list of protected areas in western Mexico (2) To assess adequacy of protection accorded to these areas (3) To identify needs of individual protected areas (4) To identify areas of importance in terms of biodiversity that lack protection (5) To promote cooperative international conservation efforts in western Mexico With these goals in mind, we present this book. It is a unique product because it represents a collaboration among many communities of people interested in conservation in Mexico: conservationists, land managers, and academics C Mexicans and U.S. Americans. Moreover, instead of trying to resolve the conservation problems of the entire Neotropics, we have focused on partnerships within western Mexico, and feel that our efforts are made more fruitful by commitment to work with colleagues, collaborators, and friends within that one region. It is our hope that much of the information compiled here will prove useful to land managers, conservationists, and biologists both within and outside Mexico. Conservation workers within Mexico are the people working “at the front” of the battle, and additional information may assist them in their efforts. We do, however, consider our primary audience to be outsiders—conservation groups, biologists, and land managers in the U.S. and other countries—looking to initiate or increase their commitment to conservation in Mexico. With regard to information provided in this book, the reader will note some inconsistencies in details between areas. To some degree, these differences can be attributed to the number of authors contributing. On the other hand, they also reflect part of the reality of Mexico. Some sites have well-documented and reasonably complete avian inventories and other information relevant to conservation, whereas many others have only the most rudimentary informationCsome lack even basic bird lists. Hence, to provide many potentially useful details consistently across areas and states becomes quite challenging. Other discrepancies arise from lack of information and variable methodologies for identifying potential conservation sites. High priority areas may have been overlooked, and sites recommended provide only a preliminary list. Their inclusion does serve a purpose, however, if for no other reason, than to draw attention to the need for additional protected areas. Overall, these gaps in knowledge gaps make offering realistic comparisons or conservation appraisals virtually impossible. This book, then, is a compilation of information regarding the protected natural areas of seven states in western Mexico. Much of it was written by specialists from Mexico—people who work towards conservation and understanding the biology of the areas and their faunas and floras—we are convinced that these are the 2 people who best understand the situations at each site, and across each state. Although the information we present here is certainly incomplete, our hope is that it is sufficient to provide an impulse towards gathering more information, and towards protecting better natural habitats across western Mexico. We anticipate publishing future versions of this book electronically over the World Wide Web, so as to make possible revisions and updates as necessary. Charles S. Aid and Michael F.
