Fort Valley Experimental Forest—A Century of Research 1908-2008. Conference Proceedings; August 7-9, 2008; Flagstaff, AZ. Proceedings RMRS-P-53CD. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 408 p. Abstract One hundred years ago, the USFS began its forest research program in a two-room cabin near Flagstaff, Arizona, with one staff person, Gustaf A. Pearson. The site became known as the Fort Valley Experiment Station and was the first in a national network of research sites developed to address uncertainties regarding the rehabilitation and conservation for forest and range lands in the nation. Fort Valley’s name has changed over the century and for today’s reader, Fort Valley Experimental Forest (FVEF) is used. The conference recognized pioneering silvicultural, range, and watershed research and how the work continues today. Invited papers and contributed poster papers were presented during the first day of the conference. The second day’s schedule included field trips and the dedication of new monuments at the historic Fort Valley Experimental Forest headquarters. The conference consisted of USFS retired researchers, current scientists, and students that addressed issues affecting the perpetuation of the ponderosa pine forest of the Southwest. Keywords: long-term research, ponderosa pine, range research, silviculture, cultural resources, Fort Valley Experimental Forest, Long Valley Experimental Forest, http://www.rmrs.nau.edu/fortvalley/ Cover photo: Fort Valley Experimental Forest headquarters in winter.

Neary, Rocky Mountain Research Station Preface The conference program committee was comprised of people long-associated with Fort Valley and its research. Our goal was to summarize the important contributions to southwestern forest and range management that evolved from Fort Valley-based projects. We pulled folks from retirement to prepare the invited papers that list past and present research endeavors. We are extremely grateful for their willingness to, at least once more, put pen to paper and share their vast experiences. We also thank those who prepared poster papers that consist primarily of the most recent research occurring on the Fort Valley Experimental Forest. Daniel P. Huebner, RMRS, provided invaluable help with the technical side to these proceedings. The Conference Planning committee included: Diane T. Jacobs, Brenda Strohmeyer, Jose Iniguez, Cody Stropki, Doc Smith, Brian Geils, Daniel G. Neary, Margaret Moore, David R. Patton, and Peter F.

  • Michael Kenney Paleozoic Stratigraphy of the Grand Canyon
    Michael Kenney Paleozoic Stratigraphy of the Grand Canyon The Paleozoic Era spans about 250 Myrs of Earth History from 541 Ma to 254 Ma (Figure 1). Within Grand Canyon National Park, there is a fragmented record of this time, which has undergone little to no deformation. These still relatively flat-lying, stratified layers, have been the focus of over 100 years of geologic studies. Much of what we know today began with the work of famed naturalist and geologist, Edwin Mckee (Beus and Middleton, 2003). His work, in addition to those before and after, have led to a greater understanding of sedimentation processes, fossil preservation, the evolution of life, and the drastic changes to Earth’s climate during the Paleozoic. This paper seeks to summarize, generally, the Paleozoic strata, the environments in which they were deposited, and the sources from which the sediments were derived. Tapeats Sandstone (~525 Ma – 515 Ma) The Tapeats Sandstone is a buff colored, quartz-rich sandstone and conglomerate, deposited unconformably on the Grand Canyon Supergroup and Vishnu metamorphic basement (Middleton and Elliott, 2003). Thickness varies from ~100 m to ~350 m depending on the paleotopography of the basement rocks upon which the sandstone was deposited. The base of the unit contains the highest abundance of conglomerates. Cobbles and pebbles sourced from the underlying basement rocks are common in the basal unit. Grain size and bed thickness thins upwards (Middleton and Elliott, 2003). Common sedimentary structures include planar and trough cross-bedding, which both decrease in thickness up-sequence. Fossils are rare but within the upper part of the sequence, body fossils date to the early Cambrian (Middleton and Elliott, 2003).

  • Fort Valley Experimental Forest-A Century of Research 1908-2008
    Vascular Plant Checklist of the Chimney Spring and Limestone Flats Prescribed Burning Study Areas Within Ponderosa Pine Experimental Forests in Northern Arizona Catherine Scudieri, School of Forestry, Northern Arizona University, Flagstaff, AZ, USFS, Rocky Mountain Research Station, Flagstaff, AZ; James F. Fowler, Carolyn Hull Sieg, USFS, Rocky Mountain Research Station, Flagstaff, AZ; Laura Williams, Department of Biological Sciences, Northern Arizona University, Flagstaff, AZ; and Sally M. Haase, USFS, Pacific Southwest Research Station, Riverside, CA Abstract—This paper presents a vascular plant species list for two sites that are part of a long-term study exploring the effects of varying fire intervals on forest characteristics includ- ing the abundance and composition of understory vegetation. The Chimney Spring study area is on the Fort Valley Experimental Forest near Flagstaff, AZ, and the Limestone Flats study area is on the Long Valley Experimental Forest, 90 km (56 mi) southeast of Flagstaff. Since 1976 (Chimney Spring) and 1977 (Limestone Flats), three replicates of each of seven burn intervals (1, 2, 4, 6, 8, 10 years, plus unburned) have been maintained by the USFS Pacific Southwest Research Station. Each study area encompasses approximately 40 to 48 ha (99 to 119 acres) of dense ponderosa pine (Pinus ponderosa) forest. Our plant species list was generated through systematic sampling of the understory vegetation in 2006 and 2007 as well as surveys of the entire study areas for additional species. We documented a total of 147 species, with 96 species found at Chimney Spring and 123 species at Limestone Flats. There are eight introduced species on the list, with six introduced species found at Chimney Spring and seven found at Limestone Flats.
