Using tree-ring methods, we dated deadwood to AD 815– 1350 and infer from death dates that the eruption occurred in late summer AD 1350. Based on wood anatomy, we identified deadwood species as Pinus albicaulis, P. monticola, P. lambertiana, P. contorta, P. jeffreyi, and Tsuga mertensiana. Only P. albicaulis grows at these elevations currently; P. lambertiana is not locally native. Using contemporary distributions of the species, we modeled paleoclimate during the time of sympatry to be significantly warmer (+3.2°C annual minimum temperature) and slightly drier (−24 mm annual precipitation) than present, resembling values projected for California in the next 70–100 yr. © 2006 University of Washington.

LANPHERE U.S. GeologicalSurvey, Menlo Park, California 94025 Long Valley caldera, a 17- by 32-km elliptical depressionon the east front of the Sierra Nevada, formed 0.7 m.y. ago during eruption of the Bishoptuff. Subsequentintracaldera volcanism included eruption of (1) aphyric rhyolite 0.68-0.64 m.y. ago during resurgentdoming of the caldera floor, (2) porphyritic hornblende-biotiterhyolite from centersperipheral to the resurgentdome at 0.5, 0.3, and 0.1 m.y. ago, and (3) porphyritic hornblende-biotiterhyodacite from outer ring fractures0.2 m.y. ago to 50,000 yr ago, a sequencethat apparently records progressivecrystallization of a subjacentchemically zoned magma chamber. Holocene rhyolitic and phreatic eruptions suggestthat residual magma was present in the chamber as recentlyas 450 yr ago. Intracaldera hydrothermalactivity beganat least0.3 m.y. ago and was widespreadin the caldera moat; it has sincedeclined due to self-sealingof near-surfacecaldera sediments by zeolitization, argillization, and silicificationand has becomelocalized on recentlyreactivated north- west-trendingSierra Nevada frontal faults that tap hot water at depth.

  • Sierra Nevada Framework FEIS Chapter 3
    table of contrents Sierra Nevada Forest Plan Amendment – Part 4.6 4.6. Vascular Plants, Bryophytes, and Fungi4.6. Fungi Introduction Part 3.1 of this chapter describes landscape-scale vegetation patterns. Part 3.2 describes the vegetative structure, function, and composition of old forest ecosystems, while Part 3.3 describes hardwood ecosystems and Part 3.4 describes aquatic, riparian, and meadow ecosystems. This part focuses on botanical diversity in the Sierra Nevada, beginning with an overview of botanical resources and then presenting a more detailed analysis of the rarest elements of the flora, the threatened, endangered, and sensitive (TES) plants. The bryophytes (mosses and liverworts), lichens, and fungi of the Sierra have been little studied in comparison to the vascular flora. In the Pacific Northwest, studies of these groups have received increased attention due to the President’s Northwest Forest Plan. New and valuable scientific data is being revealed, some of which may apply to species in the Sierra Nevada. This section presents an overview of the vascular plant flora, followed by summaries of what is generally known about bryophytes, lichens, and fungi in the Sierra Nevada. Environmental Consequences of the alternatives are only analyzed for the Threatened, Endangered, and Sensitive plants, which include vascular plants, several bryophytes, and one species of lichen. 4.6.1. Vascular plants4.6.1. plants The diversity of topography, geology, and elevation in the Sierra Nevada combine to create a remarkably diverse flora (see Section 3.1 for an overview of landscape patterns and vegetation dynamics in the Sierra Nevada). More than half of the approximately 5,000 native vascular plant species in California occur in the Sierra Nevada, despite the fact that the range contains less than 20 percent of the state’s land base (Shevock 1996).

  • 5.1 Historic Period Human Interaction with the Watershed
    Upper Carson River Watershed Stream Corridor Assessment 5. Human Interaction With the Watershed 5.1 Historic Period Human Interaction With the Watershed The purpose of this section is to summarize human activities that have had some effect on the Carson River watershed in Alpine County, California. Regional prehistory and ethnography are summarized by Nevers (1976), Elston (1982), d’Azevedo (1986), and Lindstrom et al. (2000). Details of regional history can be found in Maule (1938), Jackson (1964), Dangberg (1972), Clark (1977), Murphy (1982), Marvin (1997), and other sources. A book published by the Centennial Book Committee (1987) contains an excellent selection of historic photographs. Particularly useful is a study on the historical geography of Alpine County by Howatt (1968). 5.1.1 Prehistoric Land Use Human habitation of the Upper Carson River Watershed extends thousands of years back into antiquity. Archaeological evidence suggests use of the area over at least the last 8,000 to 9,000 years. For most of that time, the land was home to small bands of Native Americans. Their number varied over time, depending on regional environmental conditions. For at least the last 2,000 years, the Washoe occupied the Upper Carson River Watershed. Ethnographic data provides clues as to past land use and land management practices (see extended discussions in Downs 1966; Blackburn and Anderson 1993; Lindstrom et al. 2000; Rucks 2002). A broad range of aboriginal harvesting and hunting practices, fishing, and camp tending would have affected the landscape and ecology of the study area. Shrubs such as service berry and willow were pruned to enhance growth.
