Overview of Management and Restoration Activities in the Salton Sea Name Redacted Specialist in Natural Resources Policy
Overview of Management and Restoration Activities in the Salton Sea name redacted Specialist in Natural Resources Policy May 26, 2004 Congressional Research Service 7-.... www.crs.gov RL31820 CRS Report for Congress Prepared for Members and Committees of Congress Overview of Management and Restoration Activities in the Salton Sea Summary The Salton Basin in southern California has supported many lakes and water bodies throughout its geological history. The most recent inland water body in the Basin is the Salton Sea, which was created from a levee break in 1905. The Salton Sea is the largest inland water body in California. In the past several decades the salinity of the Sea has been increasing, and is now considered a significant threat to the health of the current Salton Sea ecosystem. Ecosystem changes in the Sea were exemplified by several large die-offs of fish and birds that inhabit the Sea. Some of these events included endangered species such as the brown pelican. The Sea receives most of its water from agricultural drainage originating in the Imperial and Coachella Valleys in California. When water transfers from agricultural lands in these valleys to municipal water districts in San Diego were proposed to reduce California’s reliance on water from the Colorado River, concerns about the environmental impacts of these transfers on the Sea surfaced. The proposed water transfers would have resulted in less water flowing into the Salton Sea, which according to some scientists would increase the rate of evaporation in the Sea so that salinity levels would be lethal to most fish and wildlife in less than 10 years. -

Chapter 1: Introduction
1. Introduction 1.1 Introduction and Background The Sonny Bono Salton Sea National Wildlife Refuge Complex (Complex or NWRC) consists of the Sonny Bono Salton Sea National Wildlife Refuge (NWR) and Coachella Valley NWR. Although both Refuges are located within the 8,000-square-mile Salton Basin of the Colorado Desert (Figure 1-1), the purposes of these two Refuges are as different as the habitats and species they protect. The Sonny Bono Salton Sea NWR, which consists of 37,660 acres, is situated at the south end of the Salton Sea, about 20 miles north of El Centro in Imperial County, California (Figure 1-2). The purpose of this Refuge is to protect and manage habitat to support migratory birds, particularly waterfowl, and other wildlife. Thousands of shorebirds, seabirds, and waterfowl stop-over or winter at the Salton Sea (Mark Stewart/USFWS) About 75 miles to the northwest is the 3,577-acre Coachella Valley NWR, located 10 miles east of Palm Springs in Riverside County, California (Figure 1-3). The purpose of this Refuge is to protect and contribute to the long-term survival of the federally threatened Coachella Valley fringe-toed lizard (Uma inornata) and federally endangered Coachella Valley milk-vetch (Astragalus lentiginosus var. coachellae), both endemic to the active sand habitats in the Coachella Valley. The U.S. Fish and Wildlife Service (Service) prepared this Comprehensive Conservation Plan (CCP) for the Sonny Bono Salton Sea NWR and Coachella Valley NWR to guide the management of these Refuges over the next 15 years. The CCP describes future Refuge conditions and provides long-range management direction for achieving the purposes for which each Refuge was established. -

Sonny Bono Salton Sea National Wildlife Refuge Complex
Appendix J Cultural Setting - Sonny Bono Salton Sea National Wildlife Refuge Complex Appendix J: Cultural Setting - Sonny Bono Salton Sea National Wildlife Refuge Complex The following sections describe the cultural setting in and around the two refuges that constitute the Sonny Bono Salton Sea National Wildlife Refuge Complex (NWRC) - Sonny Bono Salton Sea NWR and Coachella Valley NWR. The cultural resources associated with these Refuges may include archaeological and historic sites, buildings, structures, and/or objects. Both the Imperial Valley and the Coachella Valley contain rich archaeological records. Some portions of the Sonny Bono Salton Sea NWRC have previously been inventoried for cultural resources, while substantial additional areas have not yet been examined. Seventy-seven prehistoric and historic sites, features, or isolated finds have been documented on or within a 0.5- mile buffer of the Sonny Bono Salton Sea NWR and Coachella Valley NWR. Cultural History The outline of Colorado Desert culture history largely follows a summary by Jerry Schaefer (2006). It is founded on the pioneering work of Malcolm J. Rogers in many parts of the Colorado and Sonoran deserts (Rogers 1939, Rogers 1945, Rogers 1966). Since then, several overviews and syntheses have been prepared, with each succeeding effort drawing on the previous studies and adding new data and interpretations (Crabtree 1981, Schaefer 1994a, Schaefer and Laylander 2007, Wallace 1962, Warren 1984, Wilke 1976). The information presented here was compiled by ASM Affiliates in 2009 for the Service as part of Cultural Resources Review for the Sonny Bono Salton Sea NWRC. Four successive periods, each with distinctive cultural patterns, may be defined for the prehistoric Colorado Desert, extending back in time over a period of at least 12,000 years. -

We use a stylised social-ecological model, to illustrate how a positive Dynamic systems feedback between wealth and technology may fuel local inequality. The resulting rise in local inequality can lead Critical transitions to resource degradation and critical transitions such as ecological resource collapse and unexpected increase in poverty. Further, we find that societies may evolve towards a stable state of few wealthy and manypoorin- dividuals, where the distribution of wealth depends on how access to technology is distributed. Overall, our results illustrate how access to technology may be a mechanism that fuels resource degradation and conse- quently pushes most vulnerable members of society into a poverty trap. 1.

From Predator to Parasite: Private Property, Neoliberalism, and Ecological Disaster
From Predator to Parasite: Private Property, Neoliberalism, and Ecological Disaster Jenica M. Kramer John B. Hall ABSTRACT The institution of private property forms the basis for ecological disaster. The profit-seeking of the vested interests, in conjunction with their modes of valuing nature through the apparatuses of neoclassical economics and neoliberalism proceed to degrade and destroy life on Earth. We assert that the radical, or original institutional economics (OIE) of Thorstein Veblen, further advanced by William Dugger, have crucial insights to offer the interdisciplinary fields of political ecology and ecological economics which seek to address the underlying causes and emergent complications of the unfolding, interconnected, social, and ecological crises that define our age. This inquiry will attempt to address what, to us, appears to be either overlooked or underexplored in these research communities. Namely, that the usurpation of society’s surplus production, or, the accumulation of capital, is a parasite that sustains itself not only through the exploitation of human labor, but by exploiting society and nature more broadly, resulting in the deterioration of life itself. We attest that the transformation of the obvious predator that pursues power through pecuniary gain into a parasite, undetected by its host, is realized in its most rapacious form in the global hegemonic system of neoliberal capitalism.

Ecological Consequences of Human Niche Construction: Examining Long-Term Anthropogenic Shaping of Global Species Distributions Nicole L
SPECIAL FEATURE: SPECIAL FEATURE: PERSPECTIVE PERSPECTIVE Ecological consequences of human niche construction: Examining long-term anthropogenic shaping of global species distributions Nicole L. Boivina,b,1, Melinda A. Zederc,d, Dorian Q. Fuller (傅稻镰)e, Alison Crowtherf, Greger Larsong, Jon M. Erlandsonh, Tim Denhami, and Michael D. Petragliaa Edited by Richard G. Klein, Stanford University, Stanford, CA, and approved March 18, 2016 (received for review December 22, 2015) The exhibition of increasingly intensive and complex niche construction behaviors through time is a key feature of human evolution, culminating in the advanced capacity for ecosystem engineering exhibited by Homo sapiens. A crucial outcome of such behaviors has been the dramatic reshaping of the global bio- sphere, a transformation whose early origins are increasingly apparent from cumulative archaeological and paleoecological datasets. Such data suggest that, by the Late Pleistocene, humans had begun to engage in activities that have led to alterations in the distributions of a vast array of species across most, if not all, taxonomic groups. Changes to biodiversity have included extinctions, extirpations, and shifts in species composition, diversity, and community structure. We outline key examples of these changes, highlighting findings from the study of new datasets, like ancient DNA (aDNA), stable isotopes, and microfossils, as well as the application of new statistical and computational methods to datasets that have accumulated significantly in recent decades. We focus on four major phases that witnessed broad anthropogenic alterations to biodiversity—the Late Pleistocene global human expansion, the Neolithic spread of agricul- ture, the era of island colonization, and the emergence of early urbanized societies and commercial net- works.
