THE VALE RANGELAND REHABILITATION PROGRAM: THE DESERT REPAIRED IN SOUTHEASTERN OREGON Reference Abstract Heady, Harold F., and James Bartolome. 1977. The Vale rangeland rehabilitation program: The desert repaired in southeastern Oregon. USDA For. Sen. Resour. Bull. PNW-70, 139 p., illus. Pacific Northwest Forest and Range Experiment Station, Portland, Oregon. Discusses the initiation, execution, and outcome of an 11-year program of range rehabilitation on public domain lands in southeastern Oregon. Initiated primarily to benefit the livestock industry, the investment of $10 million in range improvements also profoundly affected other multiple uses. The analysis of this large and successful program should serve as a useful guide for monitoring other range programs. KEYWORDS: Range management, range development, rehabilitation, revegetation, environment, economics (rangeland). RESEARCH SUMMARY Resource Bulletin PNW-70 1977 This report evaluates the large-scale rangeland rehabilitation program in the Vale, Oregon, District of the Bureau of Land Management. Sagebrush in combination with two grasses, the native perennial bluebunch wheatgrass and the introduced annual cheatgrass, dominates the vegetation on 90 percent of the 60- by 175-mile (100- by 180-km) area of the district. Cold winters and dry summers characterize the climate; annual precipitation averages from 7 to 12 inches (180 to 300 mm). About 24,000 persons live in the district but they are concentrated in a small region of irrigated croplands. More than half the 419 ranchers in the district had grazing permits on Federal lands in 1975. The history of livestock use and human settlement, beginning with the arrival of the fur trappers in the early 1800ts, is discussed. Major impacts came from travelers along the Oregon Trail, mining after 1863, and exploitive livestock grazing and homesteading from 1880 until 1934. Passage of the Taylor Grazing Act in 1934 initiated management of the public domain lands. The destruction of the vegetation and soil was related to the types of use. The nature of the climax vegetation, the pattern of destruction, and present range condition are inferred. Congress appropriated approximately $10 million over an 11-year period beginning in 1963 to halt erosion, stabilize the livestock industry, and benefit other land uses. The money was used to control brush on 506,000 acres (205,000 ha), to seed 267,000 acres (108,000 ha) to desirable forage species, and to build over 2,000 miles (3 330 km) of fence, 1,600 water developments, and 463 miles (741 km) of pipelines. Supervision and management of the land uses were large parts of the Vale Program. The major sagebrush control practices used either disk plows or aerially applied 2,4-D. Absence of native forage species necessitated seeding of introduced species, primarily crested wheatgrass. Attempts at reseeding without site preparation usually failed. Burning as a land treatment was not seriously considered. Extensive sampling of treated areas revealed that most attempts at land rehabilitation succeeded. Treatments reduced brush, yet rarely were all brush plants killed. Reinvasion of sagebrush occurred in almost all areas, especially shortly after treatment. Where perennial grass stands were dense, cheatgrass was usually absent, and big sagebrush only reinvaded to about 25 percent cover. Under proper management, stands with brush no more than a quarter of the total cover should last indefinitely. Livestock management formed an integral part of the Vale Program from its beginning. Currently, several hundred pastures are used in a myriad of different patterns of seasonal and-rotational use. Of 144 pastures examined, 15 percent were grazed at the same time every year; 33 percent were rotated during the growing season and every year after seed had ripened. Systems emphasized deferment until seed ripening rather than no grazing for a whole year. The original plan to use crested wheatgrass primarily for the spring turnout pastures gradually changed during the course of the Vale Program. Crested wheatgrass seedings are now managed in the same patterns as the native bluebunch wheatgrass range. The Vale Program has increased the district's estimated grazing capacity from 285,000 animal unit months (AUM's) in 1962 to 438,000 AUM's in 1975. As only 8 percent of the total district was treated with brush control and seeding, most of the increase in grazing capacity resulted from improvement of native range. Use values other than for livestock increased because of the project. The nearly 2,500 wild horses are rapidly increasing. Pronghorn antelope and bighorn sheep have increased, if not because of improved range conditions, at least along with the rehabilitation. Other wildlife species exhibited varied responses in relation to their particular habitat requirements, but none seems to have been damaged permanently by the land treatment. Water developments for livestock benefited waterfowl, and new fisheries were established. Range restoration, stimulated by the need for livestock production and made necessary by past abuses in livestock management, favorably served other range users as well. Except for soil damage from off-road vehicles, accelerated erosion has been essentially eliminated. An economic analysis of the overall program reveals that at the current $1.51 fee for an AUM costs exceed benefits by about $5 million. At the $3 market value of an AUM in the region, costs exceed benefits to livestock by only $500,000. Many continuing costs are associated with upkeep of the physical improvements, especially water developments. Users, such as hunters, campers, rockhounds, and fishermen, have benefited from the project to an amount which probably exceeds the difference between livestock income and costs. We believe the nonmarket values of the Vale Program to society, including restoration of abused and exploited natural resources, exceed even the $5 million not covered by livestock grazing at the $1.51 fee per AUM.

  • First Presbyterian Church of Klamath Falls, Oregon
    First Presbyterian Church of Klamath Falls, Oregon First Presbyterian Church of Klamath Falls (FPC) seeks a vibrant, outgoing, and loving Pastor who will be a joyful leader of our Church and an active member of our wonderful community. The Pastor will collaborate with the Elders and covenant part- ners of FPC to grow our congregation and to bring the good news of God’s Word to the people of the Klamath Basin FPC’s History and Programs First Presbyterian Church was founded on February 27, 1884, the first organized church in Klamath Falls and for 15 years the only house of worship in this southeastern Oregon pioneer town. From the beginning, FPC attracted pastors and people whose life’s goals were to teach, preach, uplift, and serve the community. At FPC’s 130-Year celebration in 2014, the mayor’s proclamation recognized our church’s critical role in providing rough-and-tumble pioneers who worked in the forests and fields with the “education, infrastructure and medical facilities and all the other elements that make a vibrant, caring community with strong values.” Our historic com- mitment to service remains in our church body’s culture and guides us to this day. FPC attracts regular weekly attendance of 210 between its contemporary and traditional Sunday service. FPC has 266 covenant partners as well as many regular attendees not yet formally affiliated with the church. Our Children’s Ministry helps children discover Christ as the adults in our congregation model our faith and invest in our children’s lives. We rejoice in the “joyful noises” as our children participate with us during our praise and worship time in the sanctuary on Sundays.

  • Bird Notes from Southeastern Oregon and Northeastern California
    194 Vol. XXI BIRD NOTES FROM SOUTHEASTERN OREGON AND NORTHEASTERN CALIFORNIA By GEORGE WILLETT WITH FIVE PHOTOS HE WRITER spent the greater part of the summer of 1918 at Malheur T Lake, Harney County, Oregon, in the interests of the United States Bio- logical Survey, and, while there, accumulated the bulk of the bird notes that make up this article. There will be found, however, a few additional items from other localities, principally from Clear Lake, Modoc County, California, and from the territory between Malheur Lake and Klamath Falls, the latter having been covered by auto in company with Dr. 0. W. Field and Mr. Stanley 11. Jewett, both of the Biological Survey. More than four months, from April 23 to August 27, were spentat’ Mal- heur Lake, so that the notes from that immediate section may be considered fairly complete for this season of the year, but those from other localities are more or less fragmentary. From April 4 to April 16 was spent at Clear Lake and, though quite a number of species of birds were observed at this time, some of the regular summer visitants had either not appeared at all or were present in small numbers at the date of my departure. The auto trip from Malheur Lake to Klamath Falls occupied nine days, from August 27 to September 4, inclusive. While on this trip we travelled almost continuously during daylighl hours and undoubtedly missed seeing many species of birds that were common in the country traversed.. The principal points touched at this time were Dia.

Palouse Falls, Washington. The Palouse River originates in Idaho and flows westward before it enters the Snake River near Lyons Ferry, Washington. About 10 kilometers north of this confluence, the river has eroded through the Wanapum Basalt and upper portion of the Grande Ronde Basalt to produce Palouse Falls, where the river drops 60 meters (198 feet) into the plunge pool below. The river’s course was created during the cataclysmic Missoula floods of the Pleistocene as ice dams along the Clark Fork River in Idaho periodically broke and reformed. These events released water from Glacial Lake Missoula, with the resulting floods into Washington creating the Channeled Scablands and Glacial Lake Lewis. Palouse Falls was created by headward erosion of these floodwaters as they spilled over the basalt into the Snake River. After the last of the floodwaters receded, the Palouse River began to follow the scabland channel it resides in today. Photograph by Stephen P. Reidel.

Unlike the western part of the state, there’s not much chance you’ll run into a bear out here, but it is definitely rattlesnake coun- try. It’s an area of sparse human population, and most of the people who live here like it that way. Cowboy is spoken here. A good way to begin your exploration of this fascinating part of the state is by traveling the Oregon Outback National Scenic Byway, breaking away from the Cascades and journeying south and east into the Great Basin via OR 31. Fort Rock Rising up out of surrounding sagebrush desert, Fort Rock is a towering jagged rock formation, technically a tuff ring, set in an ancient seabed. It is also perhaps the most famous anthropological site in Oregon, as a pair of 9,000–year old sagebrush bark sandals were discovered here. Trails lead up into the bowl of this crater-like formation, and you can scramble to the top for views of the surround- ing desert. Fort Rock has been designated a National Natural Landmark, and an Oregon State Parks interpretive display at the base of the rock does a good job of Lone tree in Harney Valley ranch country near Burns relating the natural and human history of the area. The town of Fort Rock has a museum with several pioneer-days buildings that have good potential for ghost town-like photographs. Hours and access are SOUTHEAST OREGON limited so you can’t get the best angles during the golden hours, but it is possible to make some nice images from the parking area at those times.
