It, further, compiles estimates or proposes methods for estimating the costs and losses identified. These estimates can be used for C+NVC (cost plus net value change) modeling, and can also be used to produce an estimate of the ‘economic burden’ of wildfire for the United States. The economic burden represents the impact wildfire has on the U.S. economy. Tracking the economic burden of wildfire could be used to assess return-on-investment into wildfire interventions. The economic burden is decomposed This publication is available free of charge from: of Thisfree charge from: is available publication https://doi.org/10.6028/NIST.SP.1215 into: 1. intervention costs; 2. prevention/preparedness, mitigation, suppression, and cross- cutting; 2. and into direct and indirect wildfire related (net) losses. The annualized economic burden from wildfire is estimated to be between $71.1 billion to $347.8 billion ($2016 US). Annualized costs are estimated to range from $7.6 billion to $62.8 billion. Annualized losses are estimated to range from $63.5 billion to $285.0 billion. i Contents Introduction: The Economics of Wildland/WUI Fire Management........................... 1 1.1.

(Photo credit: American Red Cross) Opposite Page: Painting of Harris Fire by Kate Dore, based on photo by Wes Schultz. 2 Introductory Statement In October of 2007, a series of large wildfires ignited and burned hundreds of thousands of acres in Southern California. The fires displaced nearly one million residents, destroyed thousands of homes, and sadly took the lives of 10 people. Shortly after the fire siege began, a team was commissioned by CAL FIRE, the U.S. Forest Service and OES to gather data and measure the response from the numerous fire agencies involved. This report is the result of the team’s efforts and is based upon the best available information and all known facts that have been accumulated. In addition to outlining the fire conditions leading up to the 2007 siege, this report presents statistics —including availability of firefighting resources, acreage engaged, and weather conditions—alongside the strategies that were employed by fire commanders to create a complete day-by-day account of the firefighting effort. The ability to protect the lives, property, and natural resources of the residents of California is contingent upon the strength of cooperation and coordination among federal, state and local firefighting agencies.

The project includes implementation of a long-term vegetation management program that would address the North American Electric Reliability Corporation’s reliability standard (FAC-003) and other regulatory requirements that seek to minimize the risk of power outages and fires from vegetation contact with transmission lines on or near the right of way for electrical transmission lines1. In addition to implementation of the vegetation management program, the proposed project would include repairs and replacements for culverts associated with transmission line access roads and construction of a sand storage shed to stockpile sand for winter road treatments needed for access during winter months. Construction activities associated with the proposed project would occur within existing SFPUC facility and right of way boundaries in Stanislaus County, Mariposa County, and Tuolumne County, and would not require the acquisition of new property. Project implementation involving vegetation management would be ongoing. Construction activities and duration for culvert repair and/or replacement would vary along the transmission corridor, but would be short-term in nature, generally requiring a few of days to a couple of weeks to complete.

Abstract Between 2017 and 2019, California experienced a series of devastating wildfires that together led over one million people to be ordered to evacuate. Due to the speed of many of these wildfires, residents across California found themselves in challenging evacuation situations, often at night and with little time to escape. These evacuations placed considerable stress on public resources and infrastructure for both transportation and sheltering.

  • Adapt to More Wildfire in Western North American Forests As Climate
    PERSPECTIVE PERSPECTIVE Adapt to more wildfire in western North American forestsasclimatechanges Tania Schoennagela,1, Jennifer K. Balcha,b, Hannah Brenkert-Smithc, Philip E. Dennisond, Brian J. Harveye, Meg A. Krawchukf, Nathan Mietkiewiczb, Penelope Morgang, Max A. Moritzh, Ray Raskeri, Monica G. Turnerj, and Cathy Whitlockk,l Edited by F. Stuart Chapin III, University of Alaska, Fairbanks, AK, and approved February 24, 2017 (received for review October 25, 2016) Wildfires across western North America have increased in number and size over the past three decades, and this trend will continue in response to further warming. As a consequence, the wildland–urban in- terface is projected to experience substantially higher risk of climate-driven fires in the coming decades. Although many plants, animals, and ecosystem services benefit from fire, it is unknown how ecosystems will respond to increased burning and warming. Policy and management have focused primarily on spec- ified resilience approaches aimed at resistance to wildfire and restoration of areas burned by wildfire through fire suppression and fuels management. These strategies are inadequate to address a new era of western wildfires. In contrast, policies that promote adaptive resilience to wildfire, by which people and ecosystems adjust and reorganize in response to changing fire regimes to reduce future vulnerability, are needed. Key aspects of an adaptive resilience approach are (i) recognizing that fuels reduction cannot alter regional wildfire trends; (ii) targeting fuels reduction to increase adaptation by some ecosystems and residential communities to more frequent fire; (iii) actively managing more wild and prescribed fires with a range of severities; and (iv) incentivizing and planning residential development to withstand inevitable wildfire.

Wildfire is usually triggered by dry cli- mate, volcano ash, hot wind and so on, but can be caused by human as well: a used cigarette thrown by a visitor who is unaware of envi- ronmental protection, or illegally put on a fire by someone. Wildfire has become frequent in California these years. There were 64 wildfires in record in 2017, the figure on the right shows the area destroyed by wildfire.
