Relationships between wildlife and their habitats are examined in a series of matrixes, species narratives, and distribution maps.

Committee Serial No. 89-22. Considers H.R. 4159 and related H.R. 7744, to limit predatory mammal control programs to certain species in particular localities where substantial damage or danger exists.

Forty-nine species of mammals regularly occur in California chaparral, but none lives only in chaparral. Among the 49 species, 7 are found primarily in mature chaparral, 9 in young chaparral or along ecotones between chaparral and other plant communities, and 19 in riparian areas. Five species occur in many habitats but prefer chaparral in California, and 9 have wide ranges that encompass many communities including chaparral. By altering the structure of the plant community, fire in chaparral is important in determining the distribution and abundance of mammalian populations. Fire is not permanently destructive to the mammalian fauna. Wildlife habitat can be optimized by maintaining chaparral in many age classes, by restricting fuel reduction treatments to 1 to 100 ha, by protecting all trees, and by enhancing water sources. A given area of chaparral and contains two to four common, and two to nine total, species of rodents. Seeds, fruits, and young vegetative growth are the most important plant foods in chaparral. Only 12 species of mammals are endemic to chaparral because of the limited opportunity in both time and space for speciation to occur. Only kangarro rats (Dipodomys) and chipmunks (Eutamias) have speciated in chaparral.

The first comprehensive, up-to-date treatment of mammals of Oregon since Vernon Bailey's THE MAMMALS AND LIFE ZONES OF OREGON was published in 1936. This new book provides a basic reference to mammalian life in the northwestern U.S., with descriptions of 136 extant or recently extirpated species. 122 color and 36 b&w photos, 140 maps, 150 drawings.

Neogene Mammals: New Mexico Museum of Natural History and Science Bulletin 44

This volume, first published in 1975, looks at small mammal populations with emphasis being placed on their ecology and energy dynamics. It discusses the most productive research techniques and research objectives. The second part of the book deals with the roles of small mammals in ecosystems.
