Plan for the Recovery of Desert Bighorn Sheep in New Mexico 2003-2013
PLAN FOR THE RECOVERY OF DESERT BIGHORN SHEEP IN NEW MEXICO 2003-2013 New Mexico Department of Game and Fish August 2003 Executive Summary Desert bighorn sheep (Ovis canadensis mexicana) were once prolific in New Mexico, occupying most arid mountain ranges in the southern part of the state. Over-hunting, and disease transmission from livestock are 2 primary reasons for the dramatic decline in bighorn sheep numbers throughout the west during the early 1900s. In 1980, desert bighorn were placed on New Mexico’s endangered species list. From 1992-2003, approximately 25% of bighorn were radiocollared to learn causes of mortality driving this species towards extinction. Approximately 85% of all known-cause non-hunter killed radiocollared individuals have been killed by mountain lions. Despite the lack of a native ungulate prey base in desert bighorn range, mountain lion populations remain high, leading to the hypothesis that mountain lions are subsidized predators feeding on exotic ungulates, including cattle. Lack of fine fuels from cattle grazing have resulted in a lack of fire on the landscape. This has lead to increased woody vegetation which inhibits bighorn’s ability to detect and escape from predators. Bighorn numbers in spring 2003 in New Mexico totaled 213 in the wild, and 91 at the Red Rock captive breeding facility. This is in spite of releasing 266 bighorn from Red Rock and 30 bighorn from Arizona between 1979 and 2002. Several existing herds of desert bighorn likely need an augmentation to prevent them from going extinct. The presence of domestic sheep and Barbary sheep, which pose risks to bighorn from fatal disease transmission and aggression, respectively, preclude reintroduction onto many unoccupied mountain ranges. -

DEPARTMENT OF THE INTERIOR TO ACCOMPANY UNITED STATES GEOLOGICAL SURVEY WRI REPORT 83-4118-D MAP SHOWING OUTCROPS OF GRANITIC ROCKS AND SILICIC SHALLOW-INTRUSIVE ROCKS, BASIN AND RANGE PROVINCE, NEW MEXICO Compiled by F. Allan Hills and K. A. Sargent INTRODUCTION This map report is one of a series of geologic and hydro- logic maps covering all or parts of the States within the Basin and Range province of the western United States. The map reports contain information on subjects that characterize the geohy- drology of the province, including the ground-water hydrology, ground-water quality, surface distribution of selected rock types, tectonic conditions, areal geophysics, Pleistocene lakes and marshes, and mineral and energy resources. This work is part of the U.S. Geological Survey's program for geologic and hydro- logic evalutaion of the Basin and Range province to identify potentially suitable regions for further study relative to storage of high-level nuclear waste (Bedinger, Sargent, and Reed, 1984). This map report on the granitic rocks and silicic shallow- intrusive rocks of New Mexico was prepared from published geo logic maps and reports utilizing the project guidelines of Sargent and Bedinger (1984). The map shows outcrops of mostly plutonic granitic rocks, but also of fine-grained and partly glassy, silicic, shallow-intrusive rocks. The outcrops have been grouped into numbered county areas, which are outlined on the map. The Description of Map Units includes the geologic, and if available, radiometric ages, the lithology, thickness where available, and sources of data. Because the classification of plutonic igneous rocks has changed since publication of many reports used in this study, the rock terminology in the original reports has been converted, where possible, to that adopted by the International Union of Geologic Sciences (IUGS), as reported by Streckeisen (1976). -
Pull-Apart Basins at Releasing Bends of the Sinistral Late Jurassic Mojave-Sonora Fault System
spe393-03 page 97 Geological Society of America Special Paper 393 2005 Pull-apart basins at releasing bends of the sinistral Late Jurassic Mojave-Sonora fault system Thomas H. Anderson* Department of Geology and Planetary Science, University of Pittsburgh, Pittsburgh, Pennsylvania 15260, USA Jonathan A. Nourse Geological Sciences Department, California State Polytechnic University, Pomona, California 91768, USA ABSTRACT A 200–500-km-wide belt along the southwestern margin of cratonic North America is pervaded by northwest- and east-trending faults that fl ank basins con- taining thick deposits of locally derived conglomerate and sedimentary breccia. These deposits that crop out mainly in the northern part of mainland Mexico, or southern parts of Arizona and New Mexico are unconformable at their bases, have similar Upper Jurassic and/or Lower Cretaceous stratigraphic ages, and commonly preserve volcanic components in the lower parts of upward-fi ning sections. We argue that these basins share a common structural origin, based on: (1) the presence of faults, locally preserved, that generally defi ne the basin margins, (2) similar basal units comprised of coarse conglomeratic strata derived from adjacent basement, and (3) locally preserved syntectonic relationships to bounding faults. Fault orientations, and our observation that the faults (and their associated basins) extend south to the inferred trace of the Late Jurassic Mojave-Sonora megashear, suggest that the basins formed in response to transtension associated with sinistral movement along the megashear. Northwest-striking left-lateral strike-slip faults that terminate at east-striking normal faults defi ne releasing left steps at which crustal pull-apart structures formed. -
