The rising number of high severity wildfires in California has significant ecological, economic, and health impacts. Many western American forests are adapted to frequent low severity fires. However, the majority of these forests, and particularly the mixed conifer forests of California, are not adapted to high intensity fires and do not possess fire resistance adaptations such as serotinous cones to protect seeds. Consequently, high severity fires have significant negative impacts on California forests, and the absence of low severity fires has considerably altered many fundamental ecosystem processes (Miller et al. 2008). Prior to 1900, low severity fires would burn every 6-15 years. Low severity fires are generally non-lethal, have minimal change to the overstory, and kill mainly small trees. In the past, these fires were started naturally by lightning, or by Native Americans who used low severity fires to manage the forests. …show more content…
The increase in high severity fires is largely due to historical and current fire suppression policies. Federal forest-fire management in the United States began in 1886 following the creation of the national parks, and the passage of the federal Clarke-McNary Act in 1924 began a national fire suppression regime (Stephens and Ruth 2005). Suppression of low severity fires allows surface and ladder fuels to accumulate, contributing to high severity crown fires. Today, 98-99% of all wildland fires are suppressed at less than 0.5 acres in size. Of the 4.5 million acres of land once burned on California, only 6% of this area is burned today. Fire suppression investment is still increasing with 3 billion more dollars invested in fire suppression since 2013. This investment has not prevented increases in the size or frequency of high intensity fires (Stephens 2014). There is currently no comprehensive policy that works to manage fire
In 2003, possibly one of the worst wildfires in California’s history occurred. This fire, referred to as the Cedar Fire, spread across 273,246 acres.
In October 2003, San Diego experienced the Cedar Fire that claimed 273,246 acres, 2,820 structures, and 15 lives (CAL FIRE, 2015). It gained the moniker, “The Hundred Year Fire” because another fire of its magnitude was not expected for another 100 years (San Diego Fire Facts, 2016). This expectation was short lived because four years after this fire in October 2007, San Diego experienced the largest wildfire in history (San Diego Fire Facts, 2016). This fire gained the name, “Witch Fire” (CAL FIRE, 2015).
The Rim Fire of 2013 ravaged the slopes of the Stanislaus National Forest leaving many areas severely burned and unable to recover. Restoration efforts have been made and 56,000 saplings were planted in 2016 in the most severely burned areas; but the forest still has a long way to recovery. Fires are a naturally occurring hazard in the Stanislaus National Forest, and have contributed to the replenishment, control, and sustainability of the forest; but fires of the Rim Fire's intensity are very rare. The Rim Fire destroyed over 277,314 acres of habitat, harmed many mature trees, and ruined the layers of topsoil, and increased erosion and runoff. The devastation of the Rim Fire would not be have been so intense if it weren’t for past fire
On August 12th, Los Angeles Times reported 16,500-acer wildfires grew overnight near Northern California’s wine county. The fire that started August 9th has continued to spread to nearby counties and officials fear gusty winds could continue to spread flames into dry woodlands. According to the California Department of Forestry and Fire Protections, they have prompted residents near the Napa and Yolo county lines to flee their homes; at least 150 homes were evacuated.
I have researched and learned so much information about the state of California and its Department of Forestry and Fire Protection. My purpose is to inform and educate readers about the following topics: the history of the department, the jobs and duties of the department, and also the purpose of the department.
California is one of the states affected by this problem. Every-time I watch the news, I see that Californians are coming with new technology to deal with this issue. We were experiencing lack of rain in Colorado Springs during the fires more than 2 years ago. Not only we lacked of rain fall, but the carbon release from the fires was way above of what the trees can absorb. The more fires we have in an area, the more carbon capture and release unbalance we have in the area adjacent. The quantitative data shown in your thread is a great method to find out more about this research. Great post!
Massive wildfire ravaged Northern California’s wine country since Sunday night. Wildfires whipped by strong winds have swept through the region, killing at least 10 lives and more than 20000 people are forced to evacuate and flee their homes. This is one of the most destructive wildfire events in the state’s history. More than a dozen wildfires continued to burn across eight counties, destroying 1500 homes and commercial structures according to losses reported up to Tuesday. More death and destruction are expected. Authorities have not said what caused the fires but October is typically the busiest month for wildfire in California. Therefore, they believed that the hot, extremely dry condition in October created the critical fire conditions.
Wildfire risk in California refers to the chance wildfires may occur as a result of human interference with nature. In the book, “Our Changing Climate 2012” by the California Natural Resources Agency, the author discusses how computer projections project that in the future, the global warming will increase at a higher rate. The author claims that “wildfire risk increases in California will also be driven to a large extent by changes in land use and development.”(Agency 3). In other words, developing real estate and construction increases the chance of wildfires. Gathering from the Agency, only by consciously constructing the human environment can society reduce the risks of wildfires. This awareness is relevant today because over the 2017
As wildfires continue to increase in both duration and severity, wildland–urban interface becomes an increasingly important subject in communities across the Pacific Northwest. Klamath County is no exception to this statement and, consequently, a number of actions have been taken by county officials to address the threat of wildfires to communities within the area. One such action was the development of the Klamath County Community Wildfire Protection Plan (CWPP).
Projecting the effects of fire suppression and possible cumulative effects of fire suppression and other disturbances are vital management tasks moving forward into forestry planning strategies for the future. Although the long-term effects of fire suppression in the Pacific Northwest have been monitored since the early 1900’s, it is challenging to decipher relationships between the cumulative effects of a century of suppression alongside climate change, insect outbreaks and disease and plan how to combat them effectively.
All natural causes (Acts of Nature) were eliminated as probable causes for this fire to have occurred, electrical and electrical equipment were eliminated as the power was out prior to and during the fire. There was no indication of the fire being intentionally set and no indications of smoking or other outside source of
Wildfires are a destructive yet important part of a prairies Eco-system. When a wildfire occurs it burns away invasive plants, dead grass, dead twigs, and a small portion of the wildlife, when the grass and wood are burned it releases a varying amount of carbon and nitrogen into the soil which turns it into extremely fertile ground for plants to grow in, even though life may not return for months. When wildfires don't occur for a extended amount of time, it allows the old grass and fallen organic matter to cover up the ground and block out new life and turn the prairie into a virtual wasteland until a fire
The Chicago Fire have just lost their 4th straight MLS game, losing to a tired D.C United 1-0 at home. It’s put the team into dead last of the league standings, and 5 games below .500. Since the East is so bad, Chicago is only 6 points off of a playoff spot, but they have a lot of work to do if they want to catch up. In past years, the Fire just haven’t had players that were good enough. This season is different, however. Chicago has players of top quality, like Accam, Shipp and Maloney. The issue is with coaching.
John Bailey is a Professor of Silviculture and Fire Management at OSU. In his testimony, John describes wildfire as inevitable. He links the 2017 wildfire in Oregon and West to a combination of climate change and increasing amounts of fuel. Fuels have been increasing in terms of total quantity and connectivity between the many acres and as a result, wildfires burn in increasingly large areas. The Forest Service has been making mistakes by being unable to treat the increasing surface fuels previous years before the fires. John recommends active land management which would include
Wildfires burn three million acres of forest in the United States each year, killing wildlife trees and plants. Approxemately 90 percent of them are caused by human carelessness most of the rest were started by lightning. Some plants and trees have addapted remarkably good to the threat of fire. For example, the bark of redwoods may be up to a foot thick this makes the trees fire resistant. This one characteristic help ensure the redwoods
