  	Citation × Citation Citation Abstract Copy Title: Geothermal exploration assessment and interpretation, Upper Klamath Lake Area, Klamath Basin, Oregon Author: Stark, M. Year: 1980 Data from public and private sources on the Klamath Basin geothermal resource are reviewed, synthesized, and reinterpreted. In this, the second and final phase of the work, geological, remote sensing, geochemical, temperature gradient, gravity, aeromagnetic, and electrical resistivity data sets are examined. These data were derived from surveys concentrated on the east and west shores of Upper Klamath Lake. The geological, remote sensing, and potential field data suggest a few northeast-trending discontinuities, which cross the regional north-westerly strike. The near-surface distribution of warm water appears to be related to the intersections of these lineaments and northwest-trending faults. The groundwater geochemical data are reviewed and the various reservoir temperature estimates compared. Particular attention is given to specific electrical conductivities of waters as an interpretational aid to the subsurface resistivity results. A clear trend emerges in the Klamath Falls/Olene Gap area; hotter waters are associated with higher specific conductivities. In the Nuss Lake/Stukel Mountain area the opposite trend prevails, although the relationship is somewhat equivocal; LBL-10140 Title: Geothermal exploration assessment and interpretation, Upper Klamath Lake Area, Klamath Basin, Oregon Author: Stark, M.

Year: 1976 The objective of the Energy Research Group, led by Dr Garth Harris, Executive Officer of the NZERDC, was to explore a range of energy choices open to New Zealand and to identify policies that match the choices. The range of choices is broad, both because the national resource base is diverse and because there is plenty of room for improving the efficiency with which we use energy. The trend of recent years has been towards rapid growth in energy use, i.e. a doubling every 15-20 years. But trend is not destiny and the current research shows clearly that our nation's energy future is not compelled to follow a single narrow path Title: Energy Scenarios for New Zealand Author: Maiden, C.

  	Citation × Citation Citation Abstract Copy Title: Geophysical Lineaments of Arizona Author: Lepley, L.K. Year: 1979 Photolineaments seen on satellite images are usually expressions of deep crustal ruptures. However, photolineaments are omnipresent and an independent expression of regional discontinuities is needed to help rank the photolineaments. Published gravity and magnetic contour maps of Arizona were analyzed to produce a single geophysical lineament map to indicate trends of regional basement structures. This map shows that the southwestern quarter of Arizona is dominated by a NNW-ENE orthogonal system whereas the remainder of the state is gridded by a NW-NE system. North-south systems are present throughout the state, as are EW lineaments. Arizona is transected by the WNW Texas Strand, but other shorter systems trending in the Texas direction are found throughout the state south of the Strand. The major lineament systems as seen on Landsat, gravity, and magnetic maps correlate reasonably Well with known geothermal manifestations. Many other systems are Precambrian, Paleozoic, and/or Mesozoic in age but appear to control the location of Quaternary Volcanic systems Title: Geophysical Lineaments of Arizona Author: Lepley, L.K.

Year: 1976 During the summers of 1974 and 1975, gravity and ground magnetic surveys were made over the central part of the Mineral Mountains and vicinity, Utah. The gravity survey comprised 627 gravity stations over an area of approximately 660 sq km, and included 8 gravity profiles over the Roosevelt Hot Springs KGRA. The magnetic survey comprised over 400 magnetic stations within 4 magnetic profiles. The gravity data were compiled as a terrain-corrected Bouguer gravity anomaly map with a contour interval of 2 mgal. The gravity features include: (1) generally northward-trending gravity contours with gradients along the margins of the Mineral Range, indicating that the range is a horst bounded on the east and west by the Beaver and Milford valley grabens, respectively, where the Milford Valley graben shows pronounced gravity low, which indicates a valley-fill thickness of about 1.8km; and (2) a northward-trending gravity high extends along the western flank of the Mineral Range (probably caused by high-density metamorphic rocks) Title: Gravity and Ground Magnetic Surveys of the Central Mineral Mountains, Utah.

Year: 1979 The Kingman-Williams region, Arizona, possesses few thermal waters of deep origin. Evaluation of 33 waters (8 thermal) reveals that thermal waters are restricted to the Basin and Range tectonic province; no thermal waters were found on the west margin of the Colorado Plateau. The thermal waters appear to rise along north-trending normal faults or flow in deep aquifers in Quaternary sedimentary basins of the Basin and Range province. All thermal waters have distinctive chemistry and discharge at temperatures ranjinj from 28-46°C. They Apparently issue from small isolated jeothermal reservoirs.

Final Report, June 1976--October 1978 Author: Trexler, D.T. Year: 1978 Lineament analysis as an exploration technique for geothermal energy using multi-scale, multi-format imagery and geophysical data is investigated and evaluated. Two areas in Nevada, each having distinct differences in structural style were studied. One area, which encompasses a portion of the Battle Mountain Heat Flow High, was studied to determine the relationship between regional and local structural controls and geothermal activity. Four geothermal sites within this area (Winnemucca AMS) were selected and studied in detail. These sites include: 1) Leach Hot Springs, 2) Kyle Hot Springs, 3) Beowawe geothermal area and Buffalo Valley Hot Springs. A second area encompassed by the Reno AMS Sheet was selected for further study in a region dominated by three diverse tectonic styles; these are: 1) the Sierra Nevada Front, 2) the Walker Lane, and 3) basin-and-range structures. Geothermal sites analyzed at site specific scales within the Reno AMS Sheet included Steamboat Hot Springs in the Sierra Nevada Front subprovince, Dixie Valley Hot Springs located in typical basin-and-range terrain and the Brady's-Desert Peak area which is marginal to the Walker Lane. Data products employed included LANDSAT imagery, SKYLAB photography, gravity, and aeromagnetic maps. Results of this investigation indicate that in north-central Nevada the major sites of geothermal activity are associated with northeast trending structures related to the Midas Trench lineament and that the most viable geothermal area (Beowawe is located at the intersection of the northeast trend of the Oregon-Nevada Lineament Title: Evaluation of Lineament Analysis as an Exploration Technique for Geothermal Energy, Western and Central Nevada.

Draft Recovery Plan, Chapter 2, Klamath River Recovery Unit...U.S. Department Of The Interior Year: 2008, 2005 KLAMATH RIVER RECOVERY UNIT CHAPTER OF THE BULL TROUT RECOVERY PLAN EXECUTIVE SUMMARY CURRENT SPECIES STATUS Klamath River bull trout were listed as a distinct population segment in 1998 (63 FR 31647) because they are physically isolated from other bull trout by the Pacific Ocean and several small mountain ranges in central Oregon. Recovery of bull trout in the Klamath River Recovery Unit, which includes three core areas and nine currently identified local populations, will require cooperation from Federal, State, and local agencies, and Tribal and private entities. Within the Klamath River Recovery Unit, abundance has been severely reduced and remaining populations are fragmented. HABITAT REQUIREMENTS AND LIMITING FACTORS Watershed disruption has played a major role in the decline of bull trout in the Klamath River basin. The effects of historical land use on fish habitat in the larger tributaries and mainstem rivers of the Klamath River basin have been profound. Channelization, water withdrawals, removal of streamside vegetation, and other disturbances have altered the aquatic environment by elevating water temperatures, reducing water quantity and quality, and increasing sedimentation. Changes in or disruptions to watershed processes that influence characteristics of stream channels have also influenced the dynamics and persistence of bull trout populations. Klamath River basin bull trout are threatened by habitat degradation, past and present land use management practices, agricultural water diversions, and competition or hybridization from normative brown and brook trout. As a result of past land and resource management practices, bull trout populations in the Klamath River Recovery Unit are small, disjunct, and face a high risk of extirpation. IV RECOVERY GOAL AND OBJECTIVES The goal of the bull trout recovery plan is to ensure the long-term persistence of self-sustaining, complex interacting groups of bull trout distributed across the species range, so that the species can be delisted. In order to recover bull trout in the Klamath River, the following objectives need to be met: ? Maintain current distribution of bull trout and restore distribution in previously occupied areas within the Klamath River Recovery Unit, as noted in Appendix A. ? Maintain stable or increasing trends in abundance of bull trout within the Klamath River. This objective includes the expression of all life history strategies including resident, fluvial, and adfluvial forms in the Upper Klamath Lake core area and resident and fluvial forms in the Sycan River and Upper Sprague River core areas. ? Restore and maintain suitable habitat conditions for all bull trout life history stages and strategies. In core areas and migration corridors, stable or upward trends in habitat quality are achieved through landscape-level adjustments in land management strategies designed to maintain and/or enhance structural and functional attributes of upslope, riparian, and fluvial systems. ? Conserve genetic diversity and provide opportunity for interchange of genetic material among appropriate core populations. RECOVERY CRITERIA Recovery criteria for the Klamath River Recovery Unit reflect the stated objectives and consideration of population and habitat characteristics within the recovery unit. Using four population and habitat elements, the Klamath River Recovery Unit Team categorized bull trout into three groups of relative risk: diminished, intermediate, and increased. Team members evaluated bull trout under current and potential recovered conditions based on the number of local populations, adult abundance, population trends and variability, and connectivity of the system. These elements were derived from the best scientific information available concerning bull trout population and habitat requirements. Evaluation of these elements under a recovered condition assumed that actions identified within this chapter had been implemented. 1. Distribution criteria will be met when current distribution of bull trout in the 12 local populations is maintained and distribution is expanded by establishing bull trout in areas identified as suitable for potential local populations. The number of existing local populations by core area are as follows: Upper Klamath Lake, 3; Sycan River, 2; and Upper Sprague River, 7. Achieving criterion 1 entails maintaining existing local populations and establishing additional potential local populations in all core areas in the recovery unit to maintain current and recovered distribution. To achieve criterion 1 and to ensure a core area population of no fewer than 100 adult bull trout, establishing at least 5 to 7 local populations in the Klamath Lake core area among 15 potential local populations (2 to 5 new local populations), at least 5 to 7 local populations in the Sycan River core area from among 15 potential local populations (3 to 5 new local populations), and at least 10 to 12 local populations in the Upper Sprague River core area from among 25 potential local populations (3 to 5 new local populations) is necessary. 2. Abundance criteria will be met when the estimated number of adult bull trout is at least 8,250 individuals distributed among the Upper Klamath Lake, Sycan River, and Upper Sprague River core areas, based on 10 years of monitoring data. 3. Trend criteria will be met when adult bull trout exhibit stable or increasing trends in abundance in the Upper Klamath Lake, Sycan River, and Upper Sprague River core areas, based on 2 generations (10 years) of monitoring data. VI 4. Connectivity criteria will be met when specific barriers to bull trout migration in the Klamath River Recovery Unit have been addressed. In the Klamath River Recovery Unit, this objective means addressing passage: 1) existing culverts that impede passage should be replaced, including those on Threemile Creek at U.S. Forest Service Road 110 crossing, Brownsworth Creek at U.S. Forest Service Road 34 crossing, and Brownsworth Creek both 0.75 mile and 1.25 miles above U.S. Forest Service Road 34; the culvert 0.25 mile below U.S. Forest Service Road 34 (to prevent repeated washout); the large-diameter culvert at the Boulder Creek road crossing; culverts in the upper Sycan River watershed that are identified in the Fremont National Forest inventory; and several in the North Fork Sprague River drainage, namely, on North Fork Sprague River (2), Boulder Creek (1), Dead Cow Creek (1), and Sheepy Creek (1); 2) fish passage structures should be installed at water diversions on bull trout streams, and barriers should be removed, including on Cherry, Sevenmile, Sun, and Threemile Creeks; 3) fish screens should be installed to prevent fish from entering diversion canals or pipes, including on Long, Deming, Threemile, Sun, Sevenmile, and Cherry Creeks; 4) manmade barriers and entrainment should be evaluated and remedied to promote migratory bull trout; priority watersheds include Threemile, Long, Deming, Sevenmile, Cherry, Sun, and Long Creeks. The Klamath River Recovery Unit team expects that the recovery process will be dynamic and will be refined as more information becomes available. Future adaptive management will play a major role in recovery implementation and refinement of recovery criteria. The recovery unit criteria listed above will be used to determine when the Klamath River Recovery Unit is fully contributing to recovery of the Klamath River population segment. vn ACTIONS NEEDED Recovery for bull trout will entail reducing threats to the long-term persistence of populations and their habitats, ensuring the security of multiple interacting groups of bull trout, and providing habitat and access to conditions that allow for the expression of various life history forms. The seven categories are listed in Chapter 1; tasks specific to this recovery unit are provided in this chapter. ESTIMATED COST OF RECOVERY Total cost of bull trout recovery in the Klamath River Recovery Unit is estimated at about $26 million spread over a 25-year recovery period. Successful recovery of bull trout in the recovery unit is contingent on removing threats from nonnative species, eliminating barriers to fish movement, and improving habitat conditions within the Klamath River basin. Total cost includes estimates of expenditures by local, Tribal, State, and Federal governments and by private business and individuals. Cost estimates are not provided for tasks which are normal agency responsibilities under existing authorities. The estimated costs are attributed to bull trout conservation, but other aquatic species will also benefit. ESTIMATED DATE OF RECOVERY Time required to achieve recovery depends on bull trout status, factors affecting bull trout, implementation and effectiveness of recovery tasks, and responses to recovery tasks. A tremendous amount of work will be required to restore impaired habitat, reconnect habitat, and eliminate threats from nonnative species. Three to five bull trout generations (15 to 25 years), or possibly longer, may be necessary before identified threats to the species can be significantly reduced and bull trout can be considered eligible for delisting. vin Title: Bull Trout, Salvelinus Confluentus...

(Quigley, Thomas M., tech. ed.; The Interior Columbia Basin Ecosystem Management Project: Scientific Assessment). The Assessment of Ecosystem Components in the Interior Columbia Basin and Portions of the Klamath and Great Basins provides detailed information about current conditions and trends for the biophysical and social systems within the Basin. This information can be used by land managers to develop broad land management goals and priorities and provides the context for decisions specific to smaller geographic areas. The Assessment area covers about 8 percent of the U.S. land area, 24 percent of the Nations National Forest System lands, 10 percent of the Nations BLM-administered lands, and contains about 1.2 percent of the Nations population. This results in a population density that is less than one-sixth of the U.S. average. The area has experienced recent, rapid population growth and generally has a robust, diverse economy. As compared to historic conditions, the terrestrial, aquatic, forest, and rangeland systems have undergone dramatic changes. Forested landscapes are more susceptible to fire, insect, and disease than under historic conditions. Rangelands are highly susceptible to noxious weed invasion. The disturbance regimes that operate on forest and rangeland have changed substantially, with lethal fires dominating many areas where non-lethal fires were the norm historically. Terrestrial habitats that have experienced the greatest decline include the native grassland, native shrubland, and old forest structures. There are areas within the Assessment area that have higher diversity than others. Aquatic systems are now more fragmented and isolated than historically and the introduction of non-native fish species has complicated current status of native fishes. Core habitat and population centers do remain as building blocks for restoration. Social and economic conditions within the Assessment area vary considerably, depending to a great extent on population, diversity of employment opportunities, and changing demographics. Those counties with the higher population densities and greater diversity of employment opportunities are generally more resilient to economic downturns. This Assessment provides a rich information base, including over 170 mapped themes with associated models and databases, from which future decisions can benefit.

Year: 1980 The Colado geothermal area in south-central Pershing County, Nevada is defined by hot water wells in alluvium just west of the West Humboldt Range. Geothermal gradient holes have encountered temperatures up to 113.5/sup 0/C at a depth of 76 m (250 ft) with a gradient reversal in the alluvium below this depth. The West Humboldt Range consists mainly of Triassic to Jurassic slaty shale to quartzite of the Auld Lang Syne Group. Carbonate rocks of the Jurassic Lovelock Formation have been thrust over pelitic rocks on the south end of the area. Erosional remnants of Tertiary tuffs and sediments overlay the metasediments in the West Humboldt Range. The principal structures are high-angle faults striking north-northwest, northeast and north-south. The horst-to-graben transition along the range front consists of several step faults trending irregularly north. The structural pattern in the west edge of the range probably continues to the west under the Quaterary alluvium where the source of the hot water is located. Thermal waters probably rise along a major fault intersection in the Mesozoic rocks then spread out in an aquifer in the alluvium. Several thrust faults are exposed south of Coal Canyon, and a structural break in the Mesozoic rock exists under the canyon.

The structural pattern in the west edge of the range probably continues to the west under the Quaterary alluvium where the source of the hot water is located. Thermal waters probably rise along a major fault intersection in the Mesozoic rocks then spread out in an aquifer in the alluvium. Several thrust faults are exposed south of Coal Canyon, and a structural break in the Mesozoic rock exists under the canyon. Several low-angle faults are present north of Coal Canyon but their effect, if any, on the geothermal occurrence is not known; DOE/ID/12079-8; ESL-38 Close

Year: 1983 The Wind River Valley, on the west slope of the Cascade Range, is a northwest-trending drainage that joins the Columbia River near Carson, Washington. The region has been heavily dissected by fluvial and glacial erosion. Ridges have sharp crests and deep subsidiary valleys typical of a mature topography, with a total relief of as much as 900 m. The region is vegetated by fir and hemlock, as Well as dense, brushy ground-cover and undergrowth. The lower 8 km of the valley is privately owned and moderately populated. The upper reaches lies within the Gifford Pinchot National Forest, and include several campgrounds and day parks, the Carson National Fish Hatchery, and the Wind River Ranger Station and Wind River Nursery of the US Forest Service. Logging activity is light due to the rugged terrain, and consequently, most valley slopes are not accessible by vehicle. The realization that a potential for significant geothermal resources exists in the Wind River area was brought about by earlier exploration activities. Geologic mapping and interpretation was needed to facilitate further exploration of the resource by providing a knowledge of possible geologic controls on the geothermal system.

To find the plant configuration which would most effectively utilize the available energy, a parametric study was performed. The study considered the desirability of supercritical, single boiler or double boiler cycles, and the relative boiler temperatures and percentage isobutane flow split between the boilers in the double cycles for geothermal fluid temperatures of 260°F to 360°F. This study was designed to discover thermodynamic trends which would point to an optimum isobutane cycle for geothermal fluid temperatures in this temperature range.

In sum, the Department of Energy makes the GPM available to the many diverse interests that make up the geothermal community for the multiple uses it may serve. This issue of the GPM points up very clearly how closely knit many of those diverse interests have become. It might well be called an international issue'' since many of its pages are devoted to news of geothermal development abroad, to the efforts of the US industry to participate in overseas development, to the support given those efforts by federal and state agencies, and to the formation of the International Geothermal Association (IGA).

Year: 1979 The purpose of this report is to forecast the 1985 production possibilities of 21 non-OPEC marginal oil producing, developing and less-developed countries (LDC), in Latin America, Africa and the Far East (including Asia), and the potential net benefit of such production to the world market. The net benefit is the quantity of oil that may be produced in excess of indigenous demand. The forecast is based on an analysis of drilling results in geological basins, and pertinent historical production and consumption trends. The extent to which production is expected to increase hinges on the status of existing fields and the quality of recent discoveries. The normal lag-time between pre-concession or pre-drilling exploration, exploration drilling, development drilling, and the installment of production facilities with ancillary transportation and marketing infrastructure, preclude any oil discovery not now undergoing development from being an important supply source in 1985. In the event national political, social and economic policies rationalize a less than maximum effort to increase production, this forecast becomes moot.

Year: 1978 Tertiary strata of the Texas Gulf Coast comprise a number of terrigenous depositional wedges, some of which thicken abruptly at their downdip ends as a result of contemporaneous movement of growth faults and underlying salt. The Frio Formation, one of these wedges, has been studied regionally by means of a grid of correlation cross sections aided by micropaleontological control. By means of these sections, the Frio was subdivided into six map units; maps of sandstone distribution within these units delineate principal elongate sandstone trends parallel to the Gulf Coast composed of deltaic, barrier-bar, and strandplain sandstones. These broad regional studies, followed by detailed local investigations, were pursued in order to delineate prospective areas for production of geopressured geothermal energy. A prospective area must meet the following minimum requirements: reservoir volume of 3 cubic miles, minimum permeability of 20 millidarcys (md), and fluid temperatures of 300° F.

The Interior Columbia Basin Ecosystem Management Project: Scientific Assessment.) The Integrated Scientific Assessment for Ecosystem Management for the Interior Columbia Basin links landscape, aquatic, terrestrial, social, and economic characterizations to describe biophysical and social systems. Integration was achieved through a framework built around six goals for ecosystem management and three different views of the future. These goals are: maintain evolutionary and ecological processes; manage for multiple ecological domains and evolutionary timeframes; maintain viable populations of native and desired non-native species; encourage social and economic resiliency; manage for places with definable values; and, manage to maintain a variety of ecosystem goods, services, and conditions that society wants. Ratings of relative ecological integrity and socioeconomic resiliency were used to make broad statements about ecosystem conditions in the Basin. Currently in the Basin high integrity and resiliency are found on 16 and 20 percent of the area, respectively. Low integrity and resiliency are found on 60 and 68 percent of the area. Different approaches to management can alter the risks to the assets of people living in the Basin and to the ecosystem itself. Continuation of current management leads to increasing risks while management approaches focusing on reserves or restoration result in trends that mostly stabilize or reduce risks. Even where ecological integrity is projected to improve with the application of active management, population increases and the pressures of expanding demands on resources may cause increasing trends in risk.

Year: 1977 Progress in an experimental and analytical research program to evaluate and improve the design of downhole heat exchangers (DHEs) for direct applications of geothermal energy is reported. Significant progress has been achieved in characterizing flows in wells and without perforated casings and DHEs installed, determination of energy extraction rates for conventional DHEs in both cased and uncased wells, and utilization of information obtained to develop and substantiate models of heat transfer within the well. Flow characterization was obtained by experimentally measuring temperature and velocity profiles. In uncased wells, there was a relatively large vertical temperature gradient (approximately 0.5{sup 0}C/m) and insignificant measured vertical flow, while for the same wells when cased the temperature gradient was essentially zero (approximately 0.03{sup 0}C/m) and a large vertically upward flow was measured (9 to 14 cm/s as measured with a hot-film anemometer). These show that a significant connection cell is established after installation of the casing. The energy extraction rates for a conventional DHE both before and after casing of a 60 m deep well was experimentally measured. In the uncased well up to 300 kW was obtained while the cased well produced over 500 kW. Analytical heat transfer models were developed for the cased well both with and without DHEs. For the cased well without a DHE, the model predicts flow rates that agree with the measured value within about 30 percent. Further, the energy extraction rates predicted by the models agree even better with the measured values. These models allow the energy extraction rates of design parameter variations to be evaluated. At this stage, only trends can be shown but with additional substantiation they should produce optimum energy extraction designs Title: Evaluation and Design of Downhole Heat Exchangers for Direct Application; Annual Report, May 1, 1976 - July 1, 1977 Author: Culver, G.G.

  	Citation × Citation Citation Abstract Copy Title: Implementation of the Endangered Species Act of 1973 (Report to the House Committee on Resources) Author: United States. Congress. House. Committee on Resources Year: 2005, 2007 I. Executive Summary There is increasing recognition from most quarters that the Endangered Species Act (ESA) needs to be improved. Exactly what those improvements should be is less uniform. This report examines the implementation of selected aspects of the endangered species program relying predominately on information provided by the primary implementing agencies, the United States Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) and offers some recommendations for possible improvements to the program. Debate over the ESA has traditionally been highly polarized. For example, compensating landowners for takings or reductions in property value has been opposed by some who argue updating the law to address this is not necessary. While consensus on other issues such as the need for increasing conservation incentives and the role states play in endangered species conservation has begun to emerge, one of the most debated aspects of ESA implementation continues to be whether the ESA is effectively conserving endangered and threatened species. While there have been significant strides in conserving individual species such as the whooping crane, red-cockaded woodpecker and gray wolf, few species have been delisted (removed from the endangered list) or downlisted (changed in status from endangered to threatened) because of successful ESA conservation efforts. Some argue that the number of recovered species is an unfair measure, asserting that the three decades the ESA has been in existence is an insufficient amount of time for the lengthy process of species recovery and point to listed species that have not gone extinct as evidence the ESA 'saves' species. From the opposing perspective, while recovery to the point of delisting may require a substantial amount of time for many species, after three decades more progress should be demonstrable through species that have recovered and been delisted. Even if a species has increased in numbers or distribution or the threats facing the species have been reduced, if it has not been delisted on the basis of recovery, the ESA's prohibitions and regulations remain applicable and the ESA should not be a 'one way street.' Of 40 total species removed from the list, 10 domestic species were delisted because of "recovery". Of 33 reclassified species, 10 domestic downlistings (a change from endangered to threatened status) reflected a reduced threat assessment which also allowed more flexibility in management. The FWS's most recent report to Congress (Fiscal years 2001-2002) shows that 77 percent of listed species fall in the 0 to 25 percent recovery achieved bracket and 2 percent fall in the 76 to 100 percent recovery achieved bracket. 39 percent of the FWS managed species are of uncertain status. Of those with an assessed trend, at one end of the spectrum are 3 percent possibly extinct, 1 percent occurring only in captivity and 21 percent declining and at the other end are 30 percent stable and 6 percent improving. These assessments however are subjective. Additionally, the assessment that a species is improving or stable may reflect, for example, a reduction in perceived threats or corrections to inaccurate threat assessments that stemmed from erroneous data rather than actual changes in species' trends that are demonstrated by improved numbers, distribution or other such measurements. Consequently, a meaningful assessment of conservation trends under the ESA using these data is not possible. The data used to list a number of species has been subsequently determined to be erroneous and species that likely do not merit classification as endangered or threatened remain listed. This can consume resources that could be directed to species that do merit listing. The assignment of recovery priorities appears highly skewed and the recovery priority for some species seems questionable. A meaningful distinction between endangered status and threatened status has been blurred as has been the framework for the mechanism of critical habitat. Expenditure reporting has improved but presents an incomplete picture of financial resources dedicated to endangered species. Workloads for litigation regarding activities such as consultation and listing under the ESA's complex structure compete for resources that could otherwise be directed at recovery efforts. The demands associated with ESA Section 4 determinations in combination with the pace of species listings and delistings, the number of possible future additions to the list and the economic impact of listings likely indicate that the current program is not sustainable.
