  	Citation × Citation Citation Abstract Copy Title: Upper Klamath Basin bull trout conservation strategy : part 1, a conceptual framework for recovery, final Author: Light, Jeffrey Year: 1996, 2008, 2005 EXECUTIVE SUMMARY This document presents the framework of a plan to reverse the decline of bull trout (Salvelinus confluentus) populations in the Klamath Basin. If successful, we expect bull trout to recover to a level where they will have a reasonable chance of long-term viability. The work is the collective effort of fish biologists, foresters, other natural resource management professionals, and local landowners representing a diverse array of interests and organizations. Together, these individuals have worked for several years to gather information pertaining to the distribution and status of Klamath bull trout populations and threats to their persistence. The members of the Bull Trout Working Group share the common desire to restore bull trout populations while at the same time sustaining their respective land use interests in the Klamath Basin. This approach provides incentives to all the interested parties to seek agreement on solutions, encouraging cooperative work on an otherwise ambitious and daunting task. The following few pages summarize the plan. Each area is covered again in greater detail in the body of the document. The goals established by the Bull Trout Working Group for this recovery plan are to (1) Secure existing bull trout populations, and (2) Expand the populations to some of their former range and numbers. We pursue these goals with a three step approach of assessment, implementation, and evaluation. We begin with a review of the distribution and status of bull trout generally, then specifically within the Klamath Basin. Next we present available data and interpretations supporting our conclusions regarding the type, magnitude, and extent of physical and biological factors or concerns that may hamper bull trout persistence. Land and fish management activities that contribute to these problem situations are then identified. This is followed by a blueprint for stepwise development and implementation of practical solutions. Finally, a monitoring plan is proposed to measure the success of the recovery efforts. The Klamath Basin Bull trout populations represent a valuable biological resource. These populations exist at the southern edge of the species' distribution, and have distinctive genetic character. In the Upper Klamath River Basin, bull trout are presently found as resident forms in eight isolated headwater streams within six small drainages. (4Headwater streams' in this document refers to very small streams, rather than rivers which are the headwaters for larger rivers). These streams occur in three general locations: they are tributaries of the Sprague River, of the Sycan River and of Upper Klamath Lake. Together, the known populations occupy approximately 23 miles (37 km) of perennial streams. Formerly, bull trout may have occurred in the mainstems of these systems (Gilbert 1897. Dambacher et al. 1992, Roger Smith, ODFW, pers. coram. 1994). In addition to existing populations, other populations are known to have recently occupied nearby streams (Cherry and Coyote creeks, the Upper Sycan River). Estimated current population sizes in each drainage range between 133 and 1,293, indicating that populations are low enough to warrant concern. These population sizes are smaller than the minimum viable population sizes predicted by conservation biology theory. A substantial risk of extirpation via natural disturbance cycles and stochastic events exists for such small populations. Streams that are presently inhabited by bull trout are typically small and spring-fed with steep gradients. They originate in the higher elevations of mountains within the Upper Klamath Basin and flow through forests where land uses range from wilderness and national parkland to commercial forestry and grazing. Eventually, these tributaries or their mainstem receiving waters leave the forest and flow through broad sagebrush-covered valleys or marshes where they widen and flatten. Here livestock grazing and agriculture are the dominant land uses. An assessment of the current situation regarding Klamath Basin bull trout was performed using existing and new information on life history, distribution, habitat requirements by lifestage, environmental requirements, exotic species interactions, angling pressure, land use interactions, habitat fragmentation, population fragmentation and many other factors. Basin-specific information on each of these factors was collected and analyzed, complemented by a thorough review of the literature. Past, present and possible future distributions of bull trout were examined. Particular emphasis was placed on determining the nature and extent of biotic interactions, because this potential agent of bull trout decline has not been thoroughly addressed in other works. Analysis of the assembled information resulted in the identification of several specific natural and anthropogenic factors which are thought to limit the distribution and persistence of bull trout. Habitat quality and quantity are affected by land use to some degree in all currently inhabited bull trout streams except upper Sun Creek. Generally, habitat conditions vary from fair to good in existing bull trout streams. We identified several land uses that have reduced habitat quality. Principal among the abiotic factors of concern is fine sediment loading from (1) road erosion, (2) stream bank and adjacent ground disturbance by livestock, and (3) Bull Trout Document - Final - - 6 - 26-Jan-96 stream-adjacent hillslope erosion from logging. Second among the abiotic factors of concern is elevated temperature. Other concerns include diminished large woody debris (LWD) recruitment, declining bank integrity, low flows, changes in stream morphology, and blocked or hindered fish passage. The relative importance of each of these factors or concerns differs by watershed, or by location within a watershed. In most cases, information on specific issues and their locations is available with sufficient resolution to allow land managers to develop action plans to address them. Possible exceptions may include Deming Creek, where Watershed Analysis has not yet been performed. Based on the assessment results to date, the following strategy was developed to address limiting factors and concerns. Competitive and genetic interactions with non-native brook trout (Salvelinus fontinalis) and brown trout (Salmo trutta) were found to be important biotic factors currently threatening the persistence of bull trout in the Klamath Basin. This conclusion was based on the almost pervasive presence of these exotic competitors and the significance of their negative interactions as determined from the literature and from local observations in headwater streams. Temperature may be a significant issue, especially for juvenile rearing, although the temperature tolerances of bull trout are not well understood. Habitat fragmentation and alteration appear to have been major issues in the past, resulting in population fragmentation, particularly at lower elevations and in larger streams where bull trout may have ranged historically. These final two factors appear less important than exotic competitors or temperature for bull trout in the current limited ranges in headwater streams, though they are important in mainstems and larger tributaries. They will need to be addressed if large scale restoration is undertaken. With the exceptions of temperature and fine sediment, brook trout have habitat requirements and environmental tolerances similar to bull trout, and they thrive in many Klamath Basin headwater streams while bull trout do not. Brown trout pose a competitive threat similar to that posed by brook trout, but the mechanisms of displacement and the areas where they occur differ. Even in environments unaltered by land management, such as Sun Creek within Crater Lake National Park, exotic trout are displacing bull trout. This conclusion is consistent with findings throughout the west, where competition with exotic species has clearly had a major effect on bull trout range, resulting in widespread declines in bull trout distribution. Changes in habitat may have altered competitive interactions between bull trout and other salmonids, both directly and indirectly. Since changes in environmental factors can exacerbate competition issues in sensitive populations, habitat condition remains a concern. Near-term, mid-term, and long-term strategy for Recovery of Bull Trout Populations Our approach to recovery of the Klamath basin's bull trout populations is a two-phase effort corresponding to near- and mid-term objectives, and an examination of possible long-term recovery objectives. It entails securing and maintaining existing populations followed by expansion into former headwater and downstream habitats, and ultimately the possibility of connecting tributaries with mainstem linkages. Assessment, research and monitoring needs associated with each phase were identified (see main body of text). Specific project details such as funding, work schedules, participant responsibilities, specific actions, implementation methods and costs are not presented but are to be developed collectively by the Bull Trout Working Group. Phase 1: Securing existing populations This phase of the recovery plan focuses on the six small drainages where bull trout populations are known to exist today. Here we wish to prevent further decline of individual populations as a step toward securing the viability of the Klamath Basin metapopulation(s).1 This is accomplished by addressing biotic and abiotic factors that threaten the persistence of these populations. The most immediate threat is the continued presence of non-native salmonids. Localized areas of habitat degradation or alteration from sediment inputs and shade removal are an additional serious concern. It may be feasible to isolate bull trout populations above barriers, followed by eradication of brook and brown trout within each isolated stream reach. This approach will be tested early in Phase 7, with particular attention to unforeseen consequences on the ecology of the test streams. Assuming it is viable, this approach will become the focus of Phases 1 & 2, in parallel with habitat enhancement efforts. Habitat enhancement is generally feasible, particularly in areas where roads or livestock are the issues. Where needed, such habitat enhancement efforts are expected to be completed as part of Phases 1&2. It will be necessary to understand the distribution of genetic variation among existing sub-populations of bull trout in order to embark on a well 1 For an understanding of metapopulation considerations, see the body of the text, in particular the section on 'Metapopulations and sub-populations' on page 60. Bull Trout Document - Final - - 7 - 26-Jan-96 directed range expansion program. Baseline data would be essential for genetic monitoring activities and for the development of stocks for establishing new sub-populations in subsequent phases. If successful, the actions taken in Phase 1 are expected to eliminate the direct threats to existing bull trout sub-populations posed by non-native salmonids. Parallel efforts to improve the in-stream physical environment to ensure habitat is suitable for bull trout are expected to eliminate proximate environmental threats to existing bull trout sub-populations. This effort will require that abiotic limiting factors and concerns be addressed via land management activities, most of which fall within the realm of forest land management. Timber harvest and regeneration, roads (construction, use, and maintenance), and livestock grazing programs are considered. Immediate actions may take the form of road erosion abatement, including road abandonment and revegetation. Some of these actions can be accomplished when a particular unit is harvested, while others may be pursued as independent restoration activities (e.g., livestock management plans, culvert replacements). Presently, no in-stream fish habitat improvement projects have been proposed, and none are foreseen for stream reaches affected by this phase of the recovery plan. Most of the concerns related to livestock are focused within the riparian zone. Some riparian locations are much more sensitive than others, for example the large meadow in Long Creek. Actions to address these concerns will vary by landowner and location, and may range from complete riparian exclosure to short-term grazing to continuous but moderate access. The preferred actions will depend on the success of these various strategies in bringing about the desired response of the channel and fish habitat, and can be expected to change as recovery of riparian areas progresses. Effectiveness monitoring will be invaluable for measuring the success of these efforts, and in adapting our management strategy during the implementation. No water diversion concerns have been identified for this phase of the plan, except for Deming Creek, where screening of irrigation ditches may be warranted. Some additional fish management actions may also be applicable in Phase 7, for example to continue to monitor compliance with existing no kill regulations in bull trout streams. Other pertinent fish management issues have been addressed already, for example the cessation of exotic trout stocking (brook, brown or non-native rainbow) in bull trout streams. Phase 2: Expanding the range of bull trout within headwater streams In Phase 2, bull trout populations are refounded in headwater streams which now support brook trout, e.g. Calahan and Cherry creeks, or possibly in creeks without fish, e.g. Sheep Creek on the North Fork Sprague. This serves to expand the number of sub-populations, increases the number of refugia, and increases the overall size of the Klamath metapopulation(s). This is a major step in the establishment of viable metapopulations; by increasing the number of sub-populations, the effect of the loss or decline of any particular sub-population is reduced, making the metapopulation(s) more resilient to natural disturbance, variations in breeding success, disease outbreaks and other stochastic factors. Phase 2 consists of two parts: Phase 2a, in which sub-populations are founded in streams which only recently lost bull trout (e.g. Cherry Creek, Coyote Creek and the upper Sycan River) and Phase 2b, in which sub-populations are founded in other suitable headwater habitat, as indicated by the presence of thriving brook trout sub-populations (e.g. Sevenmile Creek, Calahan Creek, Annie Creek, Camp Creek, Jackson Creek, Deep Creek and Corral Creek). Both parts of Phase 2 are accomplished in much the same way as Phase 7: Barriers are constructed to exclude brook trout and brown trout, then the exotic species are eradicated above the barriers. Bull trout populations are then founded with human-introduced bull trout, whether via transplantation from wild sources or from a hatchery. Care must be exercised to maintain adequate genetic diversity in the founded sub-populations as establishment of genetically healthy populations is a non-trivial task. An inherent risk in newly created sub-populations is the loss of genetic variation (founder effect), which if great enough can reduce the vigor of the population and its long-term viability. As in Phase 7, stresses from abiotic factors, such as excessive delivery of fine sediment, low flows, or warm water temperatures, need to be reduced in parallel with the removal of exotics. Streamside roads, road crossings, low flows in upper reaches, and livestock are situations of concern in many of the streams, and warm temperatures are in some. Also as in phase 7, monitoring for the presence of exotics, bull trout population parameters, and abiotic factors is an important follow-up activity to track and ensure long-term success. In addition, genetic monitoring of newly founded populations is indicated. Bull Trout Document - Final - -8- 26-Jan-96 A possible future direction after Phase 2 Once Phase 2 is complete, the Bull Trout Working Group will pause to assess the efforts completed and plan future efforts. If phases 1 and 2 are successful, there will be significant numbers of bull trout in various tributaries, but possibly little genetic exchange between them. Bull trout range may still be restricted to headwater streams. During the evaluation and reassessment of the recovery effort, the group will re-consider the long-term recovery objectives. Based on what we know now, two possible recovery objectives are likely to be considered. The first such possible objective is the establishment of natural movement corridors between adjacent headwater streams, thereby establishing complete and viable metapopulation(s) of bull trout within the Upper Klamath Basin. Connectivity between headwater streams would allow volitional movement of bull trout. Movement would allow dispersal, founding of new sub-populations, and interbreeding between sub-populations, within the local sub-basin. Establishing natural movement corridors between headwater streams may require that selected reaches of larger tributaries or even portions of mainstem rivers be restored to suitable habitat for bull trout. This would be an ambitious undertaking, which may be infeasible. It might require the elimination or exclusion of exotics, the removal of man-made barriers which prevent movement between streams, or alterations in current land use to reduce anthropogenically induced fine sediment loads, low flows, warm stream temperatures, or changes in channel morphology. The change in focus from headwater streams to larger tributaries represents an escalation in the scale and complexity of the restoration effort. Exclusion of exotics is much more difficult. Land use effects, whether from water diversions or livestock grazing are often more significant. The second possible objective of future efforts after Phase 2 is to attemp to re-establish fluvial populations of bull trout in selected mainstem rivers of the Upper Klamath Basin, in such a way as to connect the sub-populations of each metapopulation. Fluvial bull trout are far larger than stream resident bull trout, and have much higher fecundity as a result. This gives them a tremendous advantage in breeding, whether in founding new sub-populations, or augmenting existing sub-populations. By establishing a fluvial form of bull trout in the Upper Klamath Basin, overall viability of the metapopulation(s) should be greatly increased. Timeline for implementation A prototype Phase 1 implementation is likely to be completed within 2-5 years. Full implementation of Phase 1 may take many years, but the bulk of the work could be completed in 10-20 years. Further assessment work and some aspects of Phase 2 will be accomplished concurrent with Phase 1 efforts over the next several years, but may require 5-10 years before being well underway. Specific timelines for individual projects in phases 1 and 2 and the overall recovery effort will be developed by the Bull Trout Working Group. Summary and prognosis for bull trout populations in the Upper Klamath River Basin If our analysis is accurate, the Klamath Basin's native bull trout populations are imperiled, yet their future need not be bleak. They persist today as a handful of isolated sub-populations in small, headwater streams. If a fluvial life history form existed, as it may have at one time in the Wood River2, no longer occurs or is a very small (i.e., undetectable) component of the current Klamath River Basin population. Gene flow between these sub-populations has apparently ceased. Individual population sizes are small enough to be near or below minimum viable levels as defined by current theorists in conservation biology. Competition from introduced brook and brown trout is widespread, with severe long-term consequences. Habitat conditions vary from stream to stream, depending on the nature and extent of land uses around and downstream of the bull trout tributaries. Fine sediment inputs and elevated stream temperatures are the principal habitat issue. Water withdrawals, altered channels and flood plains, and other anthropogenic influences have contributed to loss of mainstem fluvial habitat, and may have ultimately resulted in habitat fragmentation, followed by isolation of the remaining populations. Together, these conditions do not bode well for the longevity of native bull trout populations. We believe concerted efforts to resolve the identified problems can achieve the goals of maintaining, and possibly restoring, Klamath bull trout populations. Further, we believe that without attention, one or more of the identified limiting factors will almost certainly spell an end to most or all of the sub-populations in the basin. 2 A 330 mm specimen was collected from Fort Creek, a tributary to the Wood River, in 1876.

Individual population sizes are small enough to be near or below minimum viable levels as defined by current theorists in conservation biology. Competition from introduced brook and brown trout is widespread, with severe long-term consequences. Habitat conditions vary from stream to stream, depending on the nature and extent of land uses around and downstream of the bull trout tributaries. Fine sediment inputs and elevated stream temperatures are the principal habitat issue. Water withdrawals, altered channels and flood plains, and other anthropogenic influences have contributed to loss of mainstem fluvial habitat, and may have ultimately resulted in habitat fragmentation, followed by isolation of the remaining populations. Together, these conditions do not bode well for the longevity of native bull trout populations. We believe concerted efforts to resolve the identified problems can achieve the goals of maintaining, and possibly restoring, Klamath bull trout populations. Further, we believe that without attention, one or more of the identified limiting factors will almost certainly spell an end to most or all of the sub-populations in the basin. 2 A 330 mm specimen was collected from Fort Creek, a tributary to the Wood River, in 1876.

Bureau of Reclamation Year: 1931, 2008, 2006 Information Of Interest Source of water supply: Upper Klamath Lake, Lost River and Clear Lake. Area of drainage basin: 3,700 square miles. Length of irrigation season: From April 15 to September 30 - 168 days. Average elevation of irrigable area: 4,100 feet above sea level. Average annual rainfall on irrigable area: 12.7 inches. Average of recorded temperatures, 12 years: highest 97, lowest -4 F Character of soil of irragable area: Disintegrated basalt, volcanic ash, and diatomaceous eart, being largely classifid as Yakima sandy loam. Principal products: Alfalfa, hay, grain and vegetables; stock,poultry, and dairy products. Principa; markets: Portland Oregon; Sacramento and San Francisco, Ca. Limit of area of farm units: 160 acres. The irrigation plan of the Klamath Project provides for the storage of water in Upper Klamath Lake, lying just North of Klamath Falls, Oregon, and in Clear Lake Reservoir, California, at the head of Lost River. Water for lands in Langell Valley and in the vicinity of Bonanza will be supplied from Clear Lake Reservoir and from Gerber Reservoir. Water for all other lands will be supplied from Klamath Lake. Water is diverted from the outlet of Upper Klamath Lake just above the Link River Dam, into the "A" Canal which extends nine miles in a southeasterly direction, and supplies the canals on both sides of Lost River. Water for the Tule Lake lands, which are served by the "J" Canal, is discharged into Lost River from the C-G Canal and from this point to the diversion dam two miles southeast of Merrill; Lost River being used as a carrier. At the diversion dam, the water is diverted into the "J" Canal. One of the principal features of the Klamath Project is the reclamation of the lands in the bed of Tule Lake. These lands are being reclaimed in a double sense: first, by causing the waater recede and, second, by constructing irrigation works to irrigate the lands uncovered. The lowering of the water surface in Tule Lake is being brought about by evaporation from the lake itself and by preventing inflow. The works designed to prevent inflow consists of Clear Lake Reservaoir, and the Lost River diversion canal. Clear Lake Reservoir is located at the head of Lost River and stops the flood waters coming in from abouve. Flood waters coming in Lost River below Clear Lake are diverted from Lost River int the Klamath River through the diversion canal. The works designed to provede irrigation service for the uncovered lands consist of a diversion dam on Lost River tow miles southeast of Merrill, the "J" Canal and lateral system. The Keno Canal has been constructed on the West side of Link River and extends from the Link River Dam to a point about one mile below; the river in this distance makes a drop of about 50 feet. The Keno Canal was designed to develop power and to supply water for irrigation to lands on the west of Klamath River, also, to the marsh lands around Lower Klamath Lake. Irrigation from the Keno Canal has now been abandoned and the United States has installed no power plant. The Keno Canal has been leased to the California-Oregon Power Company. The Pricipal features of the project are the Clear Lake Reservoir, the Gerber Reservoir, the Link River Dam, the Main "A" Canal with a tunnel 3300 feet long, the precast concrete flume 4300 feet long on the "C" Canal, the di2 diversion dams on the Lost River, the Lost River pipe lines on the C-G Canal and the main canals and laterals and 128 miles of open drains. Irrigation service may now be provided for about 101,000 acres or irrigable land.

Bureau of Reclamation Year: 1957, 2008, 2006 INTRODUCTION AND GENERAL General Description of the Project Location. The Klamath Project is in the Upper Klamath River Basin, east of the Cascade Range. It is located in Klamath County, Oregon, and in Modoc and Siskiyou Counties of California. Project headquarters is located at the principal city of Klamath Falls, Oregon, which has a population of about 35>700, including suburbs. Smaller towns on the project in Oregon are Merrill, Malin, and Bonanza. The town of Tulelake, California, was established in 1931 near the center of the Tule Lake Division. Climate. The mean temperature for the wannest month is 630 F. The coldest month has mean temperature of 29? F. Summer nights are cool. The annual rainfall is about 13 inches, of which about 3?-inches fall during the growing season of 90 to 130 days. Topography, soils, and crops. The project area is about ^-,100 feet elevation above sea level. The surface topography is generally smooth and flat for the large areas of lake bottom, and gently sloping on the higher lands. Peat and muck soils are common in the recent lake bottoms. Soils vary from sandy loam to clay on other parts of the project. The principal crops grown are alfalfa, malting and feed barley, potatoes, clover seed, and irrigated pasture and other forage. Stock raising is an important enterprise. Industry and transportation. Farming and lumbering each provide the major portion of the economy of the Basin. Three major railroad lines, one major highway and many secondary highways, and two airlines serve the project area. Plan and purpose. The project serves 211,000 acres. The water supply is provided by two main water courses, Klamath River and Lost River and their tributaries. Besides storing, diverting, and distributing water for irrigation, project facilities have reclaimed by drainage large areas formerly inundated by Lower Klamath and Tule Lakes* Flood waters of Lost River, which terminates in Tule Lake, are diverted to the Klamath River through the Lost River Diversion Channel. This channel is also used to carry irrigation water in the opposite direction in the summertime. Another principal function of the project is water-level control for the Tule Lake and Lower Klamath Lake National Wildlife Refuges. Upper Klamath Lake on the Klamath River is the principal storage reservoir, having an active capacity of 52U,800 acre-feet. It is controlled by Link River Dam constructed, maintained, and operated INTRODUCTION AND GENERAL (Continued) General Description of the Project (Cont.) by The California Oregon Power Company under an agreement with the project whereby irrigation requirements and rights are protected.

The principal crops grown are alfalfa, malting and feed barley, potatoes, clover seed, and irrigated pasture and other forage. Stock raising is an important enterprise. Industry and transportation. Farming and lumbering each provide the major portion of the economy of the Basin. Three major railroad lines, one major highway and many secondary highways, and two airlines serve the project area. Plan and purpose. In 1958 the project provided irrigation service to 21^,500 acres. The water supply is provided by two main water courses, Klamath River and Lost River and their tributaries. Besides storing, diverting, and distributing water for irrigation, project facilities have reclaimed by drainage large areas formerly inundated by Lower Klamath and Tule Lakes. Flood waters of Lost River, which terminates In Tule Lake, are diverted to the Klamath River through the Lost River Diversion Channel. This channel is also used to carry irrigation water in the opposite direction in the summertime. Another principal function of the project is water-level control for the Tule Lake and Lower Klamath Lake National Wildlife Refuges. DTERODUCTIOH AND GBNKRAL (Continued) General Description of the Project (Cont.) Upper Klamath Lake on the Klamath River is the principal storage reservoir, having an active capacity of 52^,800 acre-feet. It is controlled by Link River Dam constructed, maintained, and operated by The California Oregon Power Company under an agreement with the project whereby irrigation requirements and rights are protected. The Main, Lower Klamath, and Tule Lake Divisions are served from this source. Gerber Reservoir on Miller Creel; and Clear Lake Reservoir on Lost River provide flood control for the Tule Lake Division and an irrigation supply for the Langell Valley Division. Their active storage capacities are 9*b3OO acre-feet and 513*300 acre-feet, respectively. Federally-financed project works also include the diversion, distribution, and drainage systems for the Main and Tule Lake Divisions; the diversion darn and main canals for the Langell Valley Division; and drainage outlets for the Lower Klamath and Tule Lake Divisions?

  	Citation × Citation Citation Abstract Copy Title: Land use and vegetation community changes at Beswick Ranch, Klamath River Canyon, California from 1955 to 2003 : focus on relationship between the irrigation and the vegetation and the land use cover Author: Bilka, Monika N. Year: 2002, 2005 Humans have altered the Klamath River Canyon in many ways. This study focuses on the years from 1955 to 2003. One substantial alteration is the conversion of terraces into irrigated pastures for agriculture and cattle ranching. This research project explains the relationships between the irrigation network and the vegetation and land use cover patterns that existed in the past and that exist today at Beswick Ranch. Data sources such as aerial photographs, maps, and other historical information are used to create Geographic Information System (GIS) maps and models of the area. Due to time constraints, the final maps and models are not complete at this time. However, the completed models were synthesized with observational data to come to preliminary conclusions. While the ditches of Shovel Creek Pasture have undergone little to no change at all since 1955, ranchers have added ditches to Faye Pasture. Ranch workers have also increased the amount of agricultural land use cover and decreased in tree cover of Faye Pasture. Conversely, ranchers increased the tree cover and non-agricultural land cover, and they have decreased the agricultural cover. The GIS coverages of Shovel Pasture remain in the preliminary stage, and further analyses of the calculated areas of land use cover and ditch lengths are needed to complete this study. In partnership with PacifiCorp and the BLM, this project aims to provide information about the impacts of the current and historical irrigation systems used on the pastures and riparian zones within this reach of the Klamath River Canyon from 1955 to 2003. Even at this stage, the preliminary coverages provide insight into the relationships between irrigation, vegetation communities, and land use cover that have occurred during the study period.
