V. PETERSON ABSTRACT This report presents results of observations of runoff and sediment yield made over a period of years at 200 reservoirs located on small drainage basins distributed throughout the western States. The records were obtained in drainage basins that are typical of much of the public domain. They are useful chiefly as an aid in assessing the need for conservation and ..in planning conservation programs and structures. The observation reservoirs are located in the Missouri River, Colorado River, and Rio Grande drainage basins, and they are distributed from Montana to southern Arizona. Of the 120 observation reservoirs in the Missouri River basin in Wyoming and Montana, 102 have records of sediment yield only and 18 have records of both sediment and runoff. In the Colorado River basin of Wyoming, Colorado, Utah, and Arizona, records were collected at 48 reservoirs, at 25 the measurements were made of sediment yield only, and at 23 measurements were for both sediment yield and runoff. Of the 32 reservoirs in the Rio Grande basin, all in New Mexico, measurements of sediment yield only were obtained at 7 and records of both runoff and sediment were obtained at 25 reservoirs. In the selection of observation reservoirs an effort was made to sample a wide range in climate, topography, geology, soil, and the types of vegetation associated with each factor within the semiarid western areas. The reservoirs range in capacity from 0.2 to 1,012 acre-feet, and the contributing drainage areas range from less than 0.1 to 55 square miles. The wide variation in unit rates of runoff and sediment yield reflect all the differences in drainage basin characteristics. INTRODUCTION The emphasis placed on programs for the conservation of soil and water on range lands in the western States during the past few years has created a need for more precise information on runoff and sediment yield from these lands. It is recognized that effective conservation of soil and water can be achieved only where information on both is available. The quantities of soil eroded, the runoff causing the 217 218 HYDROLOGY OF THE PUBLIC DOMAIN erosion, and the disposal of the soil and water must be known as a basis both for justifying a conservation program and as background for designing suitable programs. Except for forested areas at the higher altitudes, rangelands in the 11 Western States lie within the arid or semiarid zones. Water originating within the higher areas is used for irrigation of some of the lower drier lands but the irrigated tracts make up only a small part of the total area. The remaining land is used chiefly for grazing, and a large part of it is included in grazing districts and Indian reserva­ tions administered respectively by the Bureau of Land Management and the Bureau of Indian Affairs. Smaller acreages have been set aside for reclamation withdrawals, military reservations, and other public uses. Because of low precipitation the total runoff from western grazing lands is small, but generally the sediment yield is relatively high. This condition is due mainly to the fact that the major part of the runoff occurs as flash floods generated by high-intensity summer storms. Erosion during such storms is intense, and the sediment yield tends to be proportionally higher than in other localities where approximately equal amounts of runoff occur at lower rates extended over longer periods. The condition of the land, whose sparse cover of vegetation reflects both the low rainfall and often a past history of misuse, chiefly overgrazing, is also an important factor in causing the high sediment yield. Effective conservation on these lands must include methods to control the flood runoff that directly causes the excessive

Species richness as an avian community monitoring parameter. Species richness is rarely used as a long-term ecological monitoring parameter, yet it represents many characteristics that are recommended for consideration in parameter selection: it is relevant to most land-management goals, has low natural and sampling variability, and is cost effective. While species richness is less sensitive to environmental change than is abundance, it often responds to significant changes (e.g., habitat fragmentation or loss), and methods used to estimate richness allow estimation of other useful parameters (species distribu- tion, species composition). We used data collected in five national parks in southern Arizona and New Mexico to evaluate the potential of avian species richness as a parameter to detect trends in breeding bird communities. Parks surveyed repre- sent gradients in factors such as elevation, vegetation communities, and park size.

The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly affected by activities in the project area. However, determining the likelihood and extent of effects a project may have on trust resources typically requires gathering additional site-specific (e.g., vegetation/species surveys) and project-specific (e.g., magnitude and timing of proposed activities) information. Below is a summary of the project information you provided and contact information for the USFWS office(s) with jurisdiction in the defined project area.

In the bibliography, we provide website addresses for almost all of the sources cited. For the convenience of the U.S. Fish and Wildlife Service (FWS), we will also be providing these sources on CDs by postal mail. For each of the species below, we discuss FWS’s finding in terms of the Listing Factors the agency recognizes, as well as additional listing factors we urge FWS to consider in its status reviews for each of these species. To be clear, ESA Section 4 (16 U.S.C. § 1533(a)(1)) sets forth listing factors under which a species can qualify for ESA protection (see also 50 C.F.R. § 424.11(c)): A. The present or threatened destruction, modification, or curtailment of habitat or range; B. Overutilization for commercial, recreational, scientific, or educational purposes; C. Disease or predation; D. The inadequacy of existing regulatory mechanisms; and E. Other natural or manmade factors affecting its continued existence. A taxon needs to meet just one of these listing factors to qualify for ESA listing, as threatened or endangered.

Southwest Paleontological Symposium - Proceedings 2000 Mesa Southwest Museum Bulletm NO.7 Mesa Southwest Museum and Southwest Paleontological Society Mesa, Arizona Copyright 2000 PROBOSCIDEAN FOSSILS FROM THE SAN SIMON RIVER VALLEY, GRAHAM AND COCHISE COUNTIES, ARIZONA. B. J. Tegowski Richard S. White Southwest Paleontological Society Curator Southern Chapter International Wildlife Museum P.O. Box 1231 4800 Gates Pass Road Sonoita, Arizona 85637 Tucson, Arizona 85745 ABSTRACT Fossil elephants have been reported from deposits in the San Simon River Valley since 1936. We record here all known occurrences of proboscideans from that area, and record the latest find, a nearly complete skull that was recovered in 1999. The skull represents an adult Columbian Mammoth (Mammuthus columbi) which was at least 45 years old at the time of its death. We also comment on the difficulty of allocating individual teeth to either Rhynchotherium or Cuvieronius and question a number of earlier identifications. GEOGRAPHICAL AND GEOLOGICAL 1984). Wood reported "mastodon bone and teeth SETTING fragments" throughout the section at 111 Ranch, and based his specific identification on an M3 The part of the San Simon River Valley with (UA-83) from the "middle limestone unit" (Wood, which we are concerned begins near Safford, 1962:59). Wood compared his specimen to Arizona, where the San Simon River empties into Stegomastodon mirificus described by Savage the Gila River, and extends some 55 miles (1955) from the Panhandle of Texas.
