The helitankers arrived on July 1, 2022.
Cal Fire has positioned two contracted type-1 helitankers used as exclusive use for aerial firefighting operations in the LNU.
Helitanker 1CH from Columbia Helicopters will be based out of Napa County Airport, and Helitanker 37S from Siller Brothers will be based out of Sonoma Air Attack base at the Sonoma County Airport.
In addition to the unit's own Type-1 Cal Fire HAWK "Copter 104" based in Lake County, the region will now have three large helicopters not only arriving quicker to any new fire but can send local aircraft to multiple fires occurring at the same time.
These aircraft will be available for fire assignments in the greater Bay Area and all of California.
As rapid fires spread and concurrent wildfires will continue to be the norm, and areas throughout the state previously thought to be immune to large and damaging fires are proving to be as vulnerable as areas with active fire histories.
Cal Fire said the entire state is at greater risk of major fires than at any other time in recorded history.
That includes the redwood coastal belts and the more temperate areas of Northern California, as evidenced by the 2020 San Mateo and Santa Cruz Unit Lightning Complex, which burned over 86,000 acres and destroyed 1,490 structures along the coast range of Santa Cruz and San Mateo counties.
Additional surge equipment will be required to enhance Cal Fire’s ability to meet the increasing operational deficiencies created by a changing climate, meet demands caused by a year-round fire regime, and provide a deeper pool of available equipment.
In addition to Cal Fire staffed helicopters, the department relies on exclusive use contracted or “call when needed” helicopters to increase its aviation response. Contracts which are based on a call when needed premise do not guarantee the availability of a helicopter when the department calls, and these arrangements are usually implemented when a large fire is ongoing and not for initial attack response.
Cal Fire has experienced the reliability and dependability of exclusive use contracts in that they provide greater efficiencies in getting helicopters to the initial attack stage of fires.
Helitanker 1CH, a Boeing CH-47D Chinook, is owned and operated by Columbia Helicopters of
Aurora, Oregon.
Helitanker 1CH arrived at the Napa County Airport and has been on contract since June 16. This helitanker holds up to 2,800 gallons of water on a fixed tank, which is permanently attached to the aircraft. The fixed tank system also provides a safer operation since they do not have a bucket hanging underneath the helicopter while in flight.
Helitanker 37S, a Sikorsky S-64E Skycrane, is owned and operated by Siller Brothers out of Yuba City. Helitanker 37S arrived and has been on contract since July 1. This helitanker holds up to 2,000 gallons of water on a fixed tank.
“The S-64E helicopter features three experienced pilots — a command pilot, copilot and aft seat pilot, whose job is to guarantee precision on every job,” Siller Brothers reported.
These respective 2,800 and 2,000 gallon water droppers will enhance Cal Fire’s operations, ensuring that these mission critical resources are always available to respond to emergency fire events and operate safely in the field.
There will be additional firefighting resources that will help to address complex initial attack and large fire support operations. Cal Fire said this will not only increase its initial attack strength dramatically but will also reduce the time in getting these valuable resources to large fires as well.
The state also has on exclusive use contract this year three large air tankers with 3,000 and 4,000 gallon capacity as well as those normally available from Cal Fire’s partnership with the United States Forest Service.
These will be used in supporting roles behind the Cal Fire copters including the Cal Fire HAWK out of Boggs Mountain and the Cal Fire air tankers out of Sonoma, Ukiah, Sacramento and Chico, Cal Fire’s closest bases.
“Cal Fire LNU welcomes both Helitanker 1CH and 37S to the Unit and we look forward to working with both helitankers this year,” the agency said.

On July 21, 2022, the International Union for the Conservation of Nature placed the migratory monarch butterfly on its Red List of threatened species and classified it as endangered. Monarchs migrate across North America each year and are one of the continent’s most widely recognized species. The Conversation asked Oklahoma State University biologist Kristen Baum, who has studied pollinators for more than 25 years, to explain the listing’s implications for the monarch butterfly in the U.S.
What is the IUCN, and what does its action mean?
The IUCN is a network of public, private and nonprofit organizations that work to conserve nature worldwide. The Red List, which was developed in 1964, provides a standardized approach for assessing the extinction risks of species. Listing the monarch butterfly draws attention to its status and to areas where more research is needed to understand factors contributing to its decline.
The IUCN listing applies to the migratory subspecies of the monarch butterfly, or Danaus plexippus plexippus. There are two migratory populations: one east and one west of the Rocky Mountains.
The eastern population migrates thousands of miles from overwintering sites in central Mexico to breeding grounds in the Upper Midwest and southern Canada. The western population migrates from overwintering sites along the Pacific Coast in California and Baja California in Mexico to breeding grounds west of the Rocky Mountains. Monarchs in other locations throughout the world, such as in Europe and many Pacific Islands, don’t migrate and are not part of the listing.
What are the main factors threatening monarchs?
There are many factors contributing to monarchs’ decline. One of the most serious threats is habitat fragmentation and loss. Habitat fragmentation occurs when urban development or agricultural expansion break up large areas of habitat into smaller, often isolated patches. This leaves fewer areas for monarchs to find the nectar-rich plants that adult butterflies feed on, or milkweed, the sole food source for monarch caterpillars.
Other threats include pesticides, disease, climate change and invasive species. Providing more suitable habitat for monarchs in more places could help them tolerate these stresses.
Monarchs are particularly susceptible to threats during the parts of their annual cycle when many millions of them cluster together. For example, a winter storm in March 2016 killed 31%-40% of the monarchs in some overwintering colonies in central Mexico. Winter storms also blow down trees, which can reduce habitat for overwintering colonies in subsequent years.
Temperature and precipitation can influence monarchs’ spring and fall migrations and breeding season success. For example, spring weather is an important factor influencing the size of the summer monarch population. Slightly warmer and drier springs produce more monarchs on the summer breeding grounds.
Are monarch butterflies protected in the US?
Not yet, although the U.S. Fish and Wildlife Service recognizes that they are at risk.
The agency received a petition in 2014 to list the monarch butterfly as threatened under the Endangered Species Act. It concluded in 2020 that listing the monarch was warranted but precluded. This means that while monarchs are at risk of extinction, they are less at risk than other species that are currently higher priorities, such as the rusty patched bumblebee.
That decision put monarchs on the candidate list, where the agency reviews their status every year. Only a subset of species on the IUCN Red List is also protected under the Endangered Species Act. For insects, that number is less than 20%.
The IUCN report estimates that the eastern monarch population has declined by 22%-72% over the past decade, and the western population has declined by 66%-91%. Evaluating trends for insect populations can be challenging because they tend to fluctuate from year to year.
Another challenge for measuring the populations of migratory species is that patterns can differ depending on when in the annual cycle they are evaluated, such as breeding versus overwintering. To estimate how many eastern monarchs overwinter in central Mexico, scientists measure how many hectares of trees are covered with monarchs and convert that number into an estimated number of butterflies.
Many factors influence how densely monarchs cluster together in trees on their overwintering grounds. Estimates based on data from the summer breeding grounds are also challenging because monarchs go through multiple generations per year and breed across a large area.
Would an ‘endangered’ listing in the US help monarchs?
Migratory monarchs have a huge range that extends from southern Canada to central Mexico and includes all of the contiguous U.S. They use many types of open habitats, from prairies to urban parks. This makes it challenging to implement and enforce regulatory actions.
The IUCN report points out that the decline of the eastern migratory population seems to have slowed, or even stabilized, over the past 10 years. The 2014 petition to list monarchs under the U.S. Endangered Species Act spurred many actions to support monarchs that likely contributed to slowing their decline, from planting milkweeds and nectar plants in home gardens to large-scale restoration projects.
Supporting these efforts could provide more benefits than a listing under the Endangered Species Act. When a species is listed, the federal government produces a recovery plan that often includes restrictions on actions that threaten the species, such as hunting or land development. Studies have found that private land owners often become less willing to participate in conservation activities, such as allowing researchers to monitor the species on their property, after a species is listed.
It’s hard to say whether listing monarchs would have this effect. People love monarch butterflies, and community science projects that involve activities like monitoring eggs and caterpillars and tagging monarchs are very popular. Data collected by citizen scientists has expanded what researchers know about monarchs. Many of these efforts have taken place over large areas and long time spans that would be hard for scientists to replicate.
I see community scientists as critical for informing monarch conservation efforts, and hope the IUCN’s action will inspire more people to get involved.

Social media use was most likely to be linked to conduct disorder, while other forms of screen use — such as watching videos and television, playing video games, and texting — were more likely to be associated with oppositional defiant disorder (ODD).
Conduct disorder is characterized by violating others’ basic rights or societal rules with actions such as bullying, vandalism and stealing, while ODD is marked by a pattern of angry or irritable mood, argumentative or defiant behavior, and vindictiveness.
Researchers collected data on screen use, then evaluated for behavior disorders one year later. Each hour of social media was linked with a 62% higher prevalence of conduct disorder, while television, video games, video chat, and texting were linked with a 14% to 21% higher prevalence of ODD.
“Social media platforms can encourage bullying and aggression, which may contribute to the development of conduct disorder in children,” said Jason Nagata, MD, lead study author and assistant professor of pediatrics at UCSF.
“Children can be exposed to violent content on social media through ads even if they are not searching for it,” said Nagata. “If kids do search for violence, algorithms will feed back even more disturbing content and children can get stuck in cycles of toxicity.”
Watching movies and playing video games, on the other hand, may displace sleep and physical activity as well as reduce social support, he said, which could explain the tie to ODD.
In another recent study, Nagata and colleagues found that adolescents are so attached to their phones — the main vehicle for screen time — that they report losing track of time when using their phone (47.5%) and will interrupt whatever they are doing when contacted by phone (31%).
A threshold at four hours a day
Prior cross-sectional studies have suggested an association between screen time and behavior disorders but didn’t differentiate between types of screen use or only examined one type, such as video games.
The current prospective study examined links between several types of screen time and behavior in a demographically diverse national sample of 11,875 children ages 9 to 11 years old.
Children self-reported hours per day spent on six different screen modalities: viewing/streaming TV shows or movies; watching/streaming videos, such as on YouTube; playing video games; texting; video chatting; and using social media such as Instagram, separately for weekdays and weekend days.
Exceeding four hours of daily screen time may lead to disruptive behaviors through exposure to harmful content or the development of screen addictions.
The average amount of screen time was four hours per day, with the most time spent watching/streaming TV shows/movies (1.3 hours on average), playing video games (1.1 hours), and watching/streaming videos (1 hour).
In fact, four hours a day was a threshold, with time above four hours associated with a 69% higher prevalence of conduct disorder and a 46% higher prevalence of ODD.
“Some guidelines recommend limiting recreational screen time to two hours per day, but this may not be realistic for many teens,” said Nagata. “Exceeding four hours of daily screen time may lead to disruptive behaviors through exposure to harmful content or the development of screen addictions.”
To assess for behavior disorders, researchers asked parents and caregivers to complete the Kiddie Schedule for Affective Disorders and Schizophrenia, or KSADS-5, a computerized tool for categorizing child and adolescent mental health concerns, a year after their children had reported screen use.
They found 1.9% of the children met criteria for new-onset conduct disorder (1.1% of girls and 2.8% of boys) and 6.3% met criteria for new-onset oppositional defiant disorder (4.7% of girls and 7.9% of boys).
Future research could examine sleep and ADHD as potential mediators between screen use and disruptive behavior disorders, the authors wrote. “Given that the strongest association was between social media and conduct disorder, social media may be the platform to target for preventive interventions,” said Dr. Nagata.
