This is the first treatment of the mammals of the Grand Staircase–Escalante National Monument (GSENM). GSENM was established in 1996 as a 1.7-million-acre (680,000-ha) federal land reserve under the jurisdiction of the Bureau of Land Management (BLM). To successfully manage this new monument, the BLM is presently developing a management action plan. To provide information for the proper management of mammal species of the area, we have reviewed background literature for each mammal potentially found within the Monument boundaries. We propose that a core area, surrounded by a buffer matrix, be used in GSENM and surrounding public lands to preserve ecological processes in their natural state. One hundred thirteen mammalian species are categorized as follows: 82 contemporary species, 21 species questionably present, 4 introduced species reportedly in the Monument, and 6 historical species. Altogether, potentially 107 mammalian species exist there currently. Of 82 contemporary species, 11 are listed in the Utah State Sensitive Species List, 1 in the Convention on the International Trade in Endangered Species of Wild Flora and Fauna (CITES), and 1 in the World Conservation Union (IUCN) Red Book. Mammals listed under the 1973 Endangered Species Act (ESA) are noted when applicable, as well as State of Utah listings as endangered, threatened, sensitive, or extirpated. For each mammalian species listed, we present in telegraphic style a life history account, sensitivity status, and currently accepted nomenclature.
Southern Utah comprises 4 major physiographic divisions: the Great Basin, Colorado Plateau, Central Rocky Mountains, and Southern Rocky Mountains, which have been partitioned into faunal regions. We discuss the uniqueness of southern Utah and the amount of land set aside for recreation and preservation, and we encourage the study and preservation of its water resources. The stonefly (Plecoptera) fauna of 13 counties in southern Utah was surveyed. We found 58 species representing 34 genera and 8 families. Three new state records for Utah and many new county records for southern Utah are presented, along with a discussion of distribution patterns and faunal affinities of each species. Distribution patterns indicate a historical connection between the Sevier River and the Colorado drainage and a separation of faunal areas within the Central Rocky Mountains at boundaries between the Wasatch Mountains, Wasatch Plateau, and the Southern High Plateau. The uniqueness of the isolated Abajo and LaSal Mountains, the Virgin River valley, and other faunal areas in southern Utah is presented.
The milliped fauna of California consists of 11 orders, 24 families, 83 genera, and 226 species and subspecies. A complete listing of these taxa and intergrades is provided, with published and new records from the state and type localities. Cylindroiulus caeruleocinctus (Wood), C. truncorum (Silvestri), Ophyiulus pilosus (Newport) (all Julida: Julidae), and Opiona fisheri Gardner and Shelley (Chordeumatida: Caseyidae) are newly recorded from California. The new combination Atopetholus wheeleri (Chamberlin) is proposed.
