Environmental Case Study Prescribed fires in Mexico: Cerro Grande Fire Forces Evacuation May, 2000 Los Alamos, New Mexico During May 2000, New Mexico's largest recorded forest fire raged just west of Los Alamos. Fed by winds of 25 miles per hour, with gusts of up to 50 miles per hour, the Cerro Grande fire forced the evacuation of Los Alamos and came close to threatening storage facilities containing radioactive materials. The fire was controversial because it began as a normal prescribed burn, intentionally set by the National Park Service in nearby Bandelier National Monument. When it got out of hand, fingers were quickly pointed at the park service for planning that led to the loss of more than 200 homes. Prescribed burns have become a common and important part of land management in many environments. The idea behind prescribed burns in forests is that frequent small fires cause little damage to forests, are beneficial to forest ecosystems, and prevent the buildup of fuel (dead wood) that would support larger, catastrophic fires. Prescribed burns should be started only when weather conditions are safe---that is, under moderately humid conditions with little wind. During the burn, fire crews contain the fire by lighting backfires (smaller fires that eliminate fuel in a band ahead of the main fire) and by clearing firebreaks (openings across which the fire should not be able to spread). May's Cerro Grande fire began as an effort to clear fuel in Bandelier. Unfortunately, weather conditions turned dry and windy after the fire was started on May 4, and instead of burning out, the fire jumped its planned boundaries. By May 16, shortly before the fire finally ended, more than 46,000 acres had burned, and 1,200 people were working---on the ground and in planning offices---to minimize the damage. Interior Secretary Bruce Babbit declared a 30-day moratorium on prescribed burns in all western states and ordered an investigation into what went wrong at Cerro Grande. This report was released May 18. It concluded, among other things, that the fire plans had not adequately considered fuel conditions outside the planned fire boundary or taken into account 3-5-day wind forecasts. However, the general prescribed burn policy was considered sound, and prescribed fires---with careful planning---will continue to be an important part of public land management .

PREFACE hen the more than 18,000 residents of Los Alamos, New Mexico awoke W on May 6, 2000, they were unaware that within the next ninety-six hours their sleepy, relaxed mount ainside community would be forever changed. A small wildland fire approximately five miles southwest of town was rapidly growing. The fire was named for the peak of it s origin, Cerro Grande. As resident s uneasily watched the column of smoke rising from the thickly forested backdrop to town, over the next days firefighters battled the blaze with mixed success. On the morning of Wednesday, May 10th, represent atives of a wide range of government agencies, including New Mexico Governor Gary Johnson, visited Los Alamos to assess the fire.

A Process for Fire-Related Debris Flow Initiation, Cerro Grande Fire, New
HYDROLOGICAL PROCESSES Hydrol. Process. 15, 3011–3023 (2001) DOI: 10.1002/hyp.388 A process for fire-related debris flow initiation, Cerro Grande fire, New Mexico Susan H. Cannon,1* Erica R. Bigio1 and Edouard Mine2 1 US Geological Survey, Box 25046, DFC, MS 966, Denver CO 80225-0046, USA 2 Institut des Sciences et Techniques de Grenoble, Département Géotechnique, Grenoble, France Abstract: In this study we examine factors that pertain to the generation of debris flows from a basin recently burned by wildfire. Throughout the summer 2000 thunderstorm season, we monitored rain gauges, channel cross-sections, hillslope transects, and nine sediment-runoff traps deployed in a steep, 0Ð15 km2 basin burned by the May 2000 Cerro Grande fire in New Mexico. Debris flows were triggered in the monitored basin during a rainstorm on July 16, 2000, in response to a maximum 30 min rainfall intensity of 31 mm h1 (return period of approximately 2 years). Eleven other storms occurred before and after the July storm; these storms resulted in significant runoff, but did not generate debris flows. The debris flows generated by the July 16 storm initiated on a broad, open hillslope as levee-lined rills. The levees were composed of gravel- and cobble-sized material supported by an abundant fine-grained matrix. Debris-flow deposits were observed only on the hillslopes and in the first and second-order drainages of the monitored basin. No significant amounts of channel incision were measured following the passage of the debris flows, indicating that most of the material in the flows originated from the hillslopes.

Engaging Communities in Post-Fire Restoration: Forest Treatments and Community-Agency Relations After the Cerro Grande Fire
Engaging Communities in Post-Fire Restoration: Forest Treatments and Community-Agency Relations after the Cerro Grande Fire Robert L. Ryan and Elisabeth M. Hamin Department of Landscape Architecture and Regional Planning University of Massachusetts-Amherst Amherst, MA ([email protected]) ([email protected]) Introduction A wildfire is dramatic, crisis-laden, and when located near residential or business areas, very public. How managers act during a wildfire to reduce its severity is clearly critical. But forest managers also know that what happens next— how the forest is restored and post-fire community relations are managed—has just as significant long-term repercussions. In this study we asked two n a y R t r critically important questions: first, how do members e b o R : t of the nearby public perceive the treatments their i d e r c o t forest received in post-fire restoration; and second, o h P what steps did the Forest Service take that were Forest thinning after devastating successful in working with the community in the post-fire restoration period, and what additional wildfires appears to have much more community support actions could improve community relations? Our results help managers: than prefire. • Prioritize rehabilitation projects in the wildland-urban interface. • Successfully engage communities and volunteers in rehabilitation and restoration. • Improve agency-community relationships. • Assist the community in recovering from fire-related distress and associated social and economic disruption. The conclusions, presented below, are based on interviews and focus groups conducted in Los Alamos, New Mexico, after the Cerro Grande fire of 2000.

Facilitator's Field Reference
Cerro Grande Fire, Upper Frijoles Prescribed Burn– Field Reference, July 2005 Note to Facilitators: This is a suggested format. Do not feel limited by the identified stands or discussion items. It is provided as a word document so that users may adapt and revise it to fit their specific audience and time demands. Staff Ride Difficulty Rating: Physical: Arduous – This Staff Ride is considered arduous due to steep climbs and high elevation (8,900 to 10,200 feet elevation). Footing can be difficult on slopes due to clump grass, logs, and rocks, especially when wet. There are no established trails between any of the stands. The entire circuit will require 3-4 hours of actual hiking time. Logistics: Moderate – The Staff Ride is adjacent to New Mexico State Highway 4 and located approximately 12 miles west of Los Alamos, New Mexico. Paved roads provide access to the lower portion of the Staff Ride, Stands #1 and #5. Stands #2, #3, and #4 are accessible only by foot. The staff ride is located on the National Park Service – Bandelier National Monument property. In order to access the area, advanced permission must be obtained from Bandelier National Monument prior to arrival. They may require a park liaison accompany the group during the Staff Ride. Lodging and meeting accommodations are limited in the local area, but may be arranged at a few hotels in Los Alamos or White Rock. Hazards Moderate – The primary concerns are snag and hazard trees. Hard hats are required during the Staff Ride. The terrain between stands is very steep and uneven.

An Analysis of Wildland-Urban Fire with Implications for Preventing Structure Ignitions
An Analysis of Wildland-Urban Fire with Implications for Preventing Structure Ignitions Jack Cohen, PhD Research Physical Scientist US Forest Service, retired Abstract Homes and communities exposed to inevitable extreme wildfire conditions do not have to suffer inevitable fire destruction. Research shows that the characteristics of a structure and its immediate surroundings within 30 meters principally determine structure ignitions; this area is called the home ignition zone (HIZ) and defines wildland-urban (WU) fires as a structure ignition problem and not a problem of controlling inevitable wildfires. Instead of failing to control extreme wildfire behavior, an approach of reducing ignition conditions within the HIZ resulting in ignition resistant structures can provide an effective alternative for preventing structure ignitions and thus wildland-urban (WU) fire disasters without necessarily controlling extreme wildfires. Introduction The fire destruction of urban, suburban and exurban development during wildfires has come to be known as the wildland-urban interface (WUI) fire problem. The term and its close variants have been used at least since 1974 (Butler 1974). Although this community fire destruction is initiated by wildfires, structure ignitions are not determined by geographic location; rather, the fire destruction is determined by the ignition conditions of a structure in relation to its immediate surroundings. Hence, the term wildland-urban (WU) fire is used without “interface,” “intermix,” or other geographic references. Further explanation can be found in the “Defining the WU Fire Problem” section below. Recent (1990 to 2017) wildland-urban fire disasters are listed in Table 1; however, destruction of towns and villages associated with wildfires in the United States (U.S.) commonly occurred in the fifty-five to one- hundred years before the term originated (Pyne 1982).
