A reasonable first step toward conserving natural resources in parks, therefore, is to simply figure out what those natural resources are. In the late 1990s, the NPS began a program to take this first step and inventory the vascular plants and vertebrates (i.e., mammals, birds, reptiles, and amphibians) that inhabit each park with significant natural resources.
The southwestern deserts stretch from southeastern California to west Texas and then south to central Mexico. The landscape of this region is known as basin and range topography featuring to “sky islands” of forest rising from the desert lowlands which creates a uniquely diverse ecology. The region is further complicated by an international border, where governments have caused difficulties for many animal populations. This book puts a spotlight on individual research projects which are specific examples of work being done in the area and when they are all brought together, to shed a general light of understanding the biological and cultural resources of this vast region so that those same resources can be managed as effectively and efficiently as possible. The intent is to show that collaborative efforts among federal, state agency, university, and private sector researchers working with land managers, provides better science and better management than when scientists and land managers work independently.
This volume investigates the contemporary fauna that inhabit the Cuatro Ciénegas Basin. Divided into 15 chapters, it addresses and describes their diversity, taxonomic and biogeogaphic affinities, and ecological characteristics. The Cuatro Ciénegas Valley is a unique oasis in the south-central region of the State of Coahuila, part of the Sonoran Desert, in Mexico. Several clues, specially derived from the study of the microbiota, suggest a very ancient origin of the valley and its permanence through time. This condition had promoted a high level of endemism and led to unique interactions between the resident species.
This guide uses color photographs and brief descriptions to help identify a variety of plants native to the northern Chihuahuan Desert, including Big Bend National Park, Big Bend Ranch State Park, and the Davis Mountains. Split into helpful categories of trees, shrubs, succulents, wildflowers, and ferns, this guide is useful for casual visitors as well as plant enthusiasts. This light-weight, durable laminated guide's six double-panels fold for convenient carrying and use in the field.
