The CZU Lightning Complex fires were wildfires that burned in Northern California starting in August 2020. The fire complex consisted of fires in San Mateo and Santa Cruz counties, [1] including fires that had previously been separately tracked as the Warnella and Waddell fires. [2] The firefighting effort was primarily administered by the California Department of Forestry and Fire Protection (Cal Fire). [1]
The first fires started around 3:30 am on August 16, 2020, the result of a thunderstorm that produced close to 11,000 bolts of lightning and started hundreds of fires throughout California. [1] [3] These lightning strikes initially started fires separately known as the Warnella Fire, near Davenport and the Waddell Fire, near Waddell Creek, as well as three fires on what would become the northern edge of the CZU Complex fire. Two days after the fires began, a change in wind conditions caused these three northern fires to rapidly expand and merge, growing quickly to over 40,000 acres, exacerbated by conditions caused by climate change. [4] [5]
The fires destroyed 1,490 buildings, [1] including in the communities of Boulder Creek, [6] Bonny Doon, [7] Swanton, [8] and along Empire Grade Road. [9] Fires burned in both Butano [10] and Big Basin Redwoods state parks, where a number of historic buildings were destroyed, including the visitor center at Big Basin. [11] The fire also threatened to burn down the University of California, Santa Cruz campus, reaching within one mile of the campus before firefighters established two fire breaks that stopped the fire, saving both the University and the city of Santa Cruz. [12]
On September 22, Cal Fire reported that the complex, which had covered 86,509 acres (35,009 ha), had been fully contained. [1] On December 23 Cal Fire announced that the fire was controlled, stating that the fire was fully extinguished and has no risk of reignition. [13] However, it was later discovered that the fire was not quite completely extinguished; redwoods continued to smolder well into 2021. [14] [15]
The abbreviation "CZU" refers to the Cal Fire designation for its San Mateo–Santa Cruz Unit, the administrative division for San Mateo, Santa Cruz and San Francisco counties. [16]
One person died in the fires, and one other was injured. [1] [17] [18]
The documentary The CZU Fire In Their Own Words – Fighting Fires, Losing Homes, and Rebuilding Community covers the fires and was created and directed by Boulder Creek resident Peter Gelblum. [19]
Boulder Creek is a small rural mountain community in the coastal Santa Cruz Mountains. It is a census-designated place (CDP) in Santa Cruz County, California, with a population of 5,429 as of the 2020 census. Throughout its history, Boulder Creek has been home to a logging town and a resort community, as well as a counter-culture haven. Today, it is identified as the gateway to Big Basin Redwoods State Park.
Big Basin Redwoods State Park is a state park in the U.S. state of California, located in Santa Cruz County, about 36 km (22 mi) northwest of Santa Cruz. The park contains almost all of the Waddell Creek watershed, which was formed by the seismic uplift of its rim, and the erosion of its center by the many streams in its bowl-shaped depression.
The Skyline-to-the-Sea Trail is a 29.5-mile (47.5 km) hiking trail that descends from the ridge of the Santa Cruz Mountains in California to the Pacific Ocean, passing through Castle Rock State Park and Big Basin Redwoods State Park. Big Basin is California's oldest state park. It contains beautiful waterfalls and some of the largest, tallest, and oldest Redwood forests left in existence.
Waddell Creek is the name given to both the creek and the watershed that run through Big Basin Redwoods State Park in Santa Cruz County, California. The Waddell Creek mainstem is formed by the confluence of East and West Waddell Creeks, and empties into the Pacific Ocean at Waddell Beach, just south of Año Nuevo Point.
Sempervirens Fund, originally established in 1900 as Sempervirens Club, is California's oldest land trust. Founder Andrew P. Hill’s goal was to preserve the old-growth forest that became Big Basin Redwoods State Park, the first California state park in 1902. Sempervirens Fund's mission is to protect and permanently preserve coast redwood forests, wildlife habitat, watersheds, and other important natural features of California's Santa Cruz Mountains, and to encourage people to appreciate and enjoy this environment. Sempervirens Fund does this by purchasing land for protection and transferring it to state or local agencies. Sempervirens Fund has also worked to establish conservation easements and trail linkages between parks and coastal marine preserves. As of 2013, Sempervirens Fund has saved more than 34,000 acres of redwood lands.
The California Department of Forestry and Fire Protection is the fire department of the California Natural Resources Agency in the U.S. state of California. It is responsible for fire protection in various areas under state responsibility totaling 31 million acres, as well as the administration of the state's private and public forests. In addition, the department provides varied emergency services in 36 of the state's 58 counties via contracts with local governments. The department's current director is Joe Tyler, who was appointed March 4, 2022, by Governor of California Gavin Newsom.
One of the six Boy Scouts of America councils that serves the San Francisco Bay area, the Pacific Skyline Council was founded in 1940 as the Stanford Area Council (#031). In 1994, the Stanford Area Council merged with the San Mateo County Council (#020) to form the current council which serves youth in San Mateo County and northern Santa Clara county.
The 2008 California wildfire season was one of the most devastating in the state of the 21st century. While 6,255 fires occurred, about two-thirds as many as in 2007, the total area burned— 1,593,690 acres —far exceeded that of previous years.
San Vicente Redwoods is an emerging 8,500 acres (34 km2) mixed-use open space in Davenport, California. It is the largest privately owned parcel in Santa Cruz County, California, and one of the largest in California.
The Basin Complex Fire was a massive wildfire near Big Sur that ignited on June 21, 2008, and was the result of a lightning strike. It eventually grew to 162,818 acres (658.90 km2), becoming the second-largest wildfire of the 2008 California wildfire season and burning most of the Ventana Wilderness. State and federal officials spent more than $120 million to fight the fire, making it the most expensive fire in California history up to that point and the second most expensive in U.S. history, exceeded only by the Biscuit Fire in 2002. Eventually, the Thomas Fire surpassed the Basin Complex Fire in firefighting costs as well.
In terms of property damage, 2017 was the most destructive wildfire season on record in California at the time, surpassed by only the 2018 season and the 2020 season, with a total of 9,560 fires burning 1,548,429 acres (6,266.27 km2) of land, according to the California Department of Forestry and Fire Protection, including five of the 20 most destructive wildland-urban interface fires in the state's history. Throughout 2017, the fires destroyed or damaged more than 10,000 structures in the state, a higher tally than the previous nine years combined. State data showed that the large wildfires killed 47 people – 45 civilians and 2 firefighters – almost higher than the previous 10 years combined. The total property damage and total amount of burned land were both surpassed by the 2018 California wildfires.
The Tubbs Fire was a wildfire in Northern California during October 2017. At the time, the Tubbs Fire was the most destructive wildfire in California history, burning parts of Napa, Sonoma, and Lake counties, inflicting its greatest losses in the city of Santa Rosa. Its destructiveness was surpassed only a year later by the Camp Fire of 2018. The Tubbs Fire was one of more than a dozen large fires that broke out in early October 2017, which were simultaneously burning in eight Northern California counties, in what was called the "Northern California firestorm". By the time of its containment on October 31, the fire was estimated to have burned 36,810 acres (149 km2); at least 22 people were believed to have been killed in Sonoma County by the fire.
The Kincade Fire was a wildfire that burned in Sonoma County, California in the United States. The fire started northeast of Geyserville in The Geysers on 9:24 p.m. on October 23, 2019, and subsequently burned 77,758 acres (31,468 ha) until the fire was fully contained on November 6, 2019. The fire threatened over 90,000 structures and caused widespread evacuations throughout Sonoma County, including the communities of Geyserville, Healdsburg, Windsor, and Santa Rosa. The majority of Sonoma County and parts of Lake County were under evacuation warnings and orders. Lake county only had one evacuation order and that was the town of Middletown. The fire was the largest of the 2019 California wildfire season, and also the largest wildfire recorded in Sonoma County at the time before being surpassed by the LNU Lightning Complex fires in 2020.
The 2020 California wildfire season, part of the 2020 Western United States wildfire season, was a record-setting year for wildfires in California. Over the course of the year, 8,648 fires burned 4,304,379 acres (1,741,920 ha), more than four percent of the state's roughly 100 million acres of land, making 2020 the largest wildfire season recorded in California's modern history. However, it is roughly equivalent to the pre-1800 levels which averaged around 4.4 million acres yearly and up to 12 million in peak years. California's August Complex fire has been described as the first "gigafire", burning over 1 million acres across seven counties, an area larger than the state of Rhode Island. The fires destroyed over 10,000 structures and cost over $12.079 billion in damages, including over $10 billion in property damage and $2.079 billion in fire suppression costs. The intensity of the fire season has been attributed to a combination of more than a century of poor forest management and higher temperatures resulting from climate change.
The LNU Lightning Complex fires were a large complex of wildfires that burned during the 2020 California wildfire season across much of the Wine Country area of Northern California – Lake, Napa, Sonoma, Solano, and Yolo Counties, from August 17 to October 2, 2020. The complex was composed of numerous lightning-sparked fires, most of which were small. While they ignited separately from each other, the Hennessey Fire eventually grew to merge with the Gamble, Green, Markley, Spanish, and Morgan fires, scorching 192,000 acres (777 km2) by itself, for a total burn area of 363,220 acres (1,470 km2) in the complex. The fire, which burned in the hills surrounding several large cities, such as Fairfield, Napa, and Vacaville, destroyed 1,491 structures and damaged a further 232. In all, six people were killed and another five injured. The LNU Lightning Complex is the seventh-largest wildfire in the recorded history of California.
The SCU Lightning Complex fires were wildfires that burned in the Diablo Range in California in August and September 2020 as part of the 2020 California wildfire season. The fire complex consisted of fires in Santa Clara, Alameda, Contra Costa, San Joaquin, Merced, and Stanislaus counties. The name is derived from the three-letter designation given to the California Department of Forestry and Fire Protection division responsible for the Santa Clara, Alameda, Contra Costa, and parts of San Joaquin and Stanislaus counties, and the complex consisted of several distinct fires occurring in this region.
The August 2020 California lightning wildfires were a series of 650 wildfires that ignited across Northern California in mid-August 2020, due to a siege of dry lightning from rare, massive summer thunderstorms, which were caused by an unusual combination of very hot, dry air at the surface, dry fuels, and advection of moisture from the remains of Tropical Storm Fausto northward into the Bay Area. These fires burned between 1,500,000 acres (6,100 km2) to 2,100,000 acres (8,500 km2) within a 2–3 week period. The August 2020 lightning fires included three enormous wildfires: the SCU Lightning Complex, the August Complex, and the LNU Lightning Complex. On September 10, 2020, the August Complex set a record for the single-largest wildfire in the modern history of California, reaching a total area burned of 471,185 acres (1,907 km2). On September 11, the August Complex merged with the Elkhorn Fire, another massive wildfire of 255,039 acres (1,032 km2), turning the August Complex into a monster wildfire of 746,607 acres (3,021 km2).
The Western United States experienced a series of major wildfires in 2020. Severe August thunderstorms ignited numerous wildfires across California, Oregon, and Washington, followed in early September by additional ignitions across the West Coast. Fanned by strong, gusty winds and fueled by hot, dry terrains, many of the fires exploded and coalesced into record-breaking megafires, burning more than 10.2 million acres of land, mobilizing tens of thousands of firefighters, razing over ten thousand buildings, and killing at least 37 people. The fires caused over $19.884 billion in damages, including $16.5 billion in property damage and $3.384 billion in fire suppression costs. Climate change and poor forest management practices contributed to the severity of the wildfires.
The SQF Complex fire—also called the SQF Lightning Complex—was a wildfire complex that burned in Tulare County in Central California in 2020. Comprising the Castle and Shotgun fires, it affected Sequoia National Forest and adjacent areas. Both fires began on August 19, 2020, and burned a combined total of 175,019 acres before the complex as a whole was declared 100 percent contained on January 6, 2021. In the course of the fires, 232 structures were destroyed. There were no fatalities.
