  • FRIENDLY FIRE by Steve Pyne § the Warm Fire Started from a Lightning
    FRIENDLY FIRE by Steve Pyne § The Warm fire started from a lightning strike on June 8, 2006 a few miles south of Jacob Lake, between Highway 67 and Warm Springs (which gave the fire its name) and could easily have been extinguished with a canteen and a shovel. The North Kaibab instead declared it a Wildland Fire Use fire, and was delighted. Previous efforts with WFUs had occurred during the summer storm season and had yielded small, low-intensity burns that “did not produce desired effects.” The district had committed to boosting its burned acres and had engineered personnel transfers to make that happen. Since large fires historically occurred in the run-up to the summer monsoon season, when conditions were maximally hot, dry, and windy, the Warm fire promised to rack up the desired acres.1 For three days the fire behaved as hoped. On June 11 the district decided to request a Fire Use Management Team to help run the fire, which was now over a hundred acres and blowing smoke across the sole road to the North Rim, and so required ferrying vehicles under convoy. On June 13 the FUMT assumed command of the fire. Briefings included a warning that the fire could not be allowed to enter a region to the southeast which was a critical habitat for the Mexican spotted owl. The “maximum management area” allotted for the fire was 4,000 acres. That day the fire spotted across the highway, outside the prescribed zone. The FUMT and district ranger decided to seize the opportunity to allow the fire to grow and get some “bonus acres.” The prescribed zone was increased; then increased again as the fire, now almost 7,000 acres, crossed Forest Road 225, another prescribed border.

  • What a Gully
    ~~GOLLY9 WHAT A GULLY / History does not record the words spoken by Don Garcia Lopez de Cardenas, proud captain of Castile, that memorable day in 1540 when he and his companions looked into the Grand Canyon, the first Europeans to do so. In all probability those words were strong, soldierly expletives, although a footsore scribe, of a poetical bent, recorded for posterity and prying eyes in Spain that the buttes and towers of the Canyon which "appeared from above to be the height of a man were higher than the tower of the Cathedral of Seville." An apt description, my capitan! The gentle Father Garces came along in 1776 and was quite .impressed by the canyon, giving it the name of "Puerto de Bucareli" in honor of a great Viceroy of Spain. James 0. Pattie, trapper and mountain man, arrived at the canyon in 1826, the first American tourist to visit there. Unfortunately there were no comfortable Fred Harvey accommoda­ tions awaiting him and he was pretty disgusted .with the whole thing . "Horrid mountains ," he wrote . Lt . Joseph Ives , an explorer, came to the "Big Canyon" in 1857 and "paused in wondering delight" but found the region "altogether valueless. Ours has been the first and will doubtless be the last party of whites to visit this profitless locality ," was his studied opinion. But the lieutenant's feet probably were hurting him and he should be forgiven his hasty words . John Wesley Powell, twelve years later, arrived at the canyon the exc1tmg way - by boat down the Colorado. To him it was the "Grand" Canyon and so to all the world it has been ever since.

  • The Effects of Burn Entry and Burn Severity on Stand
    THE EFFECTS OF BURN ENTRY AND BURN SEVERITY ON STAND STRUCTURE AND COMPOSITION IN GRAND CANYON NATIONAL PARK Anna Marie Higgins A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science In Forestry Northern Arizona University August 2011 Approved: _________________________ Andrea Thode, Ph.D., Co-chair _________________________ Kristen Waring, Ph.D., Co-chair ________________________ Peter Fulé, Ph.D. 1 ABSTRACT THE EFFECTS OF BURN ENTRY AND BURN SEVERITY ON STAND STRUCTURE AND COMPOSITION IN GRAND CANYON NATIONAL PARK ANNA MARIE HIGGINS Over one hundred years of fire exclusion in frequent-fire ponderosa pine and mixed conifer forests has created conditions outside of the historic range of variation. Increased tree densities, heavy fuel accumulations and an increase in late successional, fire-intolerant trees have resulted in more moderate- to high- severity fire occurring when fire is reintroduced. The reduction in seral species regeneration and the negative ecological impacts associated with uncharacteristic stand-replacing fires is of concern to managers, especially in the face of a changing climate. Grand Canyon National Park began using prescribed fire in the ponderosa pine forests over 30 years ago and more recently, wildland fire in the mixed conifer forests. Manager‟s are increasingly using burn severity mapping to quantify above-ground vegetation change following fire, yet research is needed to determine post-fire vegetation response thus enabling future forest succession predictions. Our study focused on the effects of burn entry and burn severity on a subset of two forest types: ponderosa pine with white fir encroachment and dry mixed conifer.

    United States Department of the Interior U.S. Fish and Wildlife Service 2321 West Royal Palm Road, Suite 103 Phoenix, Arizona 85021 Telephone: (602) 242-0210 FAX: (602) 242-2513 AESO/SE 2-21-97-F-085 January 26, 2000 Memorandum To: Director, Intermountain Region, National Park Service, Denver, Colorado From: Field Supervisor Subject: Section 7 Consultation for New Flight Rules in the Vicinity of Grand Canyon National Park The U.S. Fish and Wildlife Service has reviewed your November 8, 1999, biological assessment on Proposed Revisions to Flight rules in the vicinity of Grand Canyon National Park, in Mohave and Coconino counties, Arizona, as specified in the Federal Register on July 9, 1999 (64 FR 37295-37301). Your request for formal section 7 consultation under the Endangered Species Act of 1973, as amended (16 U.S.C. 1531 et seq.) was received on November 10, 1999. This consultation addresses the possible effects of partial implementation of a sequential process to restore natural quiet and protect park resources. This document represents the Service's biological opinion on the effects of that action on the experimental population of the California condor (Gymnops californianus) treated as threatened without critical habitat, the bald eagle (Haliaeetus leucocephalus) threatened without critical habitat, and the Mexican spotted owl (Strix occidentalis lucida) threatened without critical habitat, in accordance with section 7 of the Act. The Service concurs with your determination that the proposed action is not likely to adversely affect the desert tortoise (Gopherus [=Xerobates] agassizii), Hualapai Mexican vole (Microtus mexicanus hualpaiensis), black-footed ferret (Mustela nigripes), southwestern willow flycatcher (Empidonax traillii extimus), or the Yuma clapper rail (Rallus longirostris yumanensis).
