As agreed with your office, we gathered information on areas managed by two agencies: the Department of the Interior’s Bureau of Land Management (BLN) and the Department of Agriculture’s Forest Service. Specifically, this report provides information on (1) legislative guidance and the agency policies governing wilderness study area management, (2) the various activities and uses occurring in the agencies’ study areas, (3) the ways these activities and uses affect the areas, and (4) agency actions to monitor and restrict these uses and to repair damage resulting from them. Appendixes I and II provide data on the number, acreage, and locations of wilderness study areas managed by BLM and the Forest Service, as well as data on the types of uses occurring in the areas. -
Reconstruction of Mid Wisconsin Environments in Southern New Mexico
Articles Arthur H. Harris Reconstruction of Mid Wisconsin Environments in Southern New Mexico Abundant vertebrate remains from two mid-Wisconsin cave deposits in New Mexico allow reconstruction of paleoenvironments. Dry Cave lies in southeastern New Mexico, U-Bar Cave in the extreme southwest (Figure 1). Both sites are in the ecotone between woodland and Chihuahuan Desert vegetations. During the mid Wisconsin, both had vertebrate species indicative of woodland, but otherwise differed greatly. Dry Cave had winter temperatures milder than those at the site today, but otherwise the climate was similar to that now found some 450 km to the north. Except for taxa allowed into the area by mild winters, extralimital forms occur in nearby highland woodlands or in northeastern New Mexico. U-Bar Cave probably lacked winter freezes, had cool summers, and had precipitation more evenly distributed than now. Taxa now as distant as the Great Basin occurred together with species from the nearer highlands. Relatively warm summers and retention of seasonal patterns of precipitation at Dry Cave in contrast to cool summers and decreased seasonality of precipitation at U-Bar Cave produced more extreme biotic differences between the sites than is the case now. Whether this was due to different contemporaneous climatic regimes or to chronological differences between the faunas is uncertain. The last major subdivision of the Pleistocene Epoch is the Wisconsin Age. Between ice advances in the early Wisconsin, terminating around 60 000 B.P., and a major renewal of glacial activity in the late Wisconsin, commencing around 32 000 to 27 000 B. P., there was a long span of less severe climatic conditions, the mid Wisconsin (see Bradley 1985 for age estimates). -
Cultural Resources Overview Desert Peaks Complex of the Organ Mountains – Desert Peaks National Monument Doña Ana County, New Mexico
Cultural Resources Overview Desert Peaks Complex of the Organ Mountains – Desert Peaks National Monument Doña Ana County, New Mexico Myles R. Miller, Lawrence L. Loendorf, Tim Graves, Mark Sechrist, Mark Willis, and Margaret Berrier Report submitted to the Wilderness Society Sacred Sites Research, Inc. July 18, 2017 Public Version This version of the Cultural Resources overview is intended for public distribution. Sensitive information on site locations, including maps and geographic coordinates, has been removed in accordance with State and Federal antiquities regulations. Executive Summary Since the passage of the National Historic Preservation Act (NHPA) in 1966, at least 50 cultural resource surveys or reviews have been conducted within the boundaries of the Desert Peaks Complex. These surveys were conducted under Sections 106 and 110 of the NHPA. More recently, local avocational archaeologists and supporters of the Organ Monument-Desert Peaks National Monument have recorded several significant rock art sites along Broad and Valles canyons. A review of site records on file at the New Mexico Historic Preservation Division and consultations with regional archaeologists compiled information on over 160 prehistoric and historic archaeological sites in the Desert Peaks Complex. Hundreds of additional sites have yet to be discovered and recorded throughout the complex. The known sites represent over 13,000 years of prehistory and history, from the first New World hunters who gazed at the nighttime stars to modern astronomers who studied the same stars while peering through telescopes on Magdalena Peak. Prehistoric sites in the complex include ancient hunting and gathering sites, earth oven pits where agave and yucca were baked for food and fermented mescal, pithouse and pueblo villages occupied by early farmers of the Southwest, quarry sites where materials for stone tools were obtained, and caves and shrines used for rituals and ceremonies. -

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.
