Extending from the spillway below Cochiti Dam, about fifty miles north of Albuquerque, to the headwaters of Elephant Butte Reservoir, near Truth or Consequences in the southern portion of New Mexico, the Middle Rio Grande Bosque is more than a cottonwood woodland or forest. It is a complete riverside ecosystem, among the more important in the world's arid regions. Every day hundreds of visitors to the bosque encounter flora and fauna they can't identify. Researchers and municipal, county, state, and federal resource agency personnel concerned with the bosque's management need to know how plants and animals are linked to their habitats. With descriptions of more than seven hundred plants and animals illustrated with color photographs, this authoritative guide is the first of its kind for the Middle Rio Grande Bosque and is an invaluable resource for land managers, teachers, students, eco-buffs, and nature enthusiasts. It also reveals the important role the bosque plays in New Mexico's natural heritage.

With over 40,000 described species, spiders have adapted to nearly every terrestrial environment across the globe. Over half of the world’s spider families live within the three contiguous Pacific Coast states—not surprising considering the wide variety of habitats, from mountain meadows and desert dunes to redwood forests and massive urban centers. This beautifully illustrated, accessible guide covers all of the families and many of the genera found along the Pacific Coast, including introduced species and common garden spiders. The author provides readers with tools for identifying many of the region’s spiders to family, and when possible, genus and species. He discusses taxonomy, distribution, and natural history as well as what is known of the habits of the spiders, the characters of families, and references to taxonomic revisions of the pertinent genera. Full-color plates for each family bring to life the incredible diversity of this ancient arachnid order.
