LAKE COUNTY, Calif. — California hasn’t lost a species in 50 years, but that could soon change if efforts to save the Clear Lake hitch fail.
The population of the hitch, a large minnow native to Clear Lake and its tributaries, is crashing, local tribes are asking state and federal agencies for immediate intervention and on Thursday the state held a virtual meeting with Lake County residents and officials to discuss the emergency.
The hitch’s troubles began decades ago. Once reported to number in the millions, over the last decade, the hitch population has plummeted.
In 2014, as the situation was accelerating, the hitch was listed as a threatened species under the California Endangered Species Act. However, the federal government hasn’t followed suit so far.
The hitch has traditionally been a primary food source for Lake County’s Pomo tribes. In December, those tribes and the Center for Biological Diversity asked the U.S. Fish and Wildlife Service to provide emergency protections to the fish. They also held a summit with state and federal agencies to discuss immediate help for the hitch.
Concerns about the hitch led to the proposal for a proclamation of a local emergency by the Board of Supervisors at the Jan. 10 meeting, but that discussion was rescheduled to Jan. 24.
On Thursday, the State Water Resources Control Board held the first of two public listening sessions about the hitch.
Thursday’s State Water board session started out with some technical issues with its Zoom link. Officials said they have updated the links to avoid that problem at the Feb. 1 session.
Valerie Zimmer of the State Water Board said there is widespread agreement that the hitch has been in decline for a long time.
She showed a graph of hitch population and juvenile spawning data collected by the United States Geological Survey.
The data showed that there has been a near complete failure of juvenile hitch success after 2017, with Zimmer noting that the decline is validated by local knowledge and narratives.
The slide showed that a small number of juveniles were recorded in 2018, a smaller number in 2019. There were no numbers given for 2020, and then in 2021 no juveniles were recorded. In 2022, only a very small number were found.
“This looks like the population is crashing right now,” she said.
With the hitch having up to a six-year life cycle, if they don’t come back this year, Zimmer said they may be gone for good.
“Unfortunately we are late to this issue,” Zimmer said, adding that the state is catching up and working with local agencies and organizations.
As for why the hitch population is crashing now, Zimmer said there is no single cause and no single person who is responsible, although the drought is having an impact.
Zimmer said the hitch’s peril is due to human activity. Examples of harmful activities include:
• Flow barriers: Culverts, stream bed alterations and dams. • Insufficient water flow volumes: Drought impacts, surface diversions and losing streams. • Habitat degradation: Mining, land use changes, levee development and flood control. • Predation and competition with invasive species • Pollution: Mercury and harmful algal blooms.
Flow barriers may be a critical issue as hitch don’t jump over barriers. Zimmer said they can migrate when there is a lot of water, but not when water is low.
A key issue is lack of flow in Lake County’s creeks. “If there’s no water in the creeks, none of this other stuff matters,” Zimmer said.
Zimmer also showed a picture of a 2014 fish kill in Adobe Creek, when juvenile hitch got stuck and died. Just a week before, the creek was running very high, so a biologist couldn't get into the creek to get the fish out.
More recently, Lake County’s tribes have carried out successful fish rescues, such as one that occurred in April when Robinson Rancheria and Habematolel Pomo tribal members worked with the Lake County Water Resources staff and the California Department of Fish and Wildlife to rescue hundreds of hitch from an isolated pool in Adobe Creek near Soda Bay in Lakeport.
Other possible factors impacting the hitch’s numbers include illegal water diversions, cannabis, turning in pumps too early, overallocated water and groundwater use, especially when wells are close to creeks. Zimmer acknowledged data gaps and a lot that isn’t known.
Zimmer said the focus is being placed on the creeks that historically have had a lot of hitch in them — Adobe, Cole, Kelsey, Manning and Middle creeks.
She showed maps of surface water diversions — irrigation, frost protection, domestic water and stock watering — as well as a map of uses like frost protection, which tends to occur in the spring when the hitch are migrating.
Primary uses for water in Lake County include urban, 13,000 acres; vineyards, 10,000 acres; fruits and nuts, 7,000 acres; pasture, 3,000 acres; and grain and hay, 1,200 acres.
Zimmer said the state is not looking at the entire county as it tries to address the situation. “We’re focusing on the areas that are important to the hitch.”
“I do think agriculture can be a really strong partner,” said Zimmer, explaining that some farmers are offering to put water into the creeks to get them moving so the fish can survive.
She said farmers also can help by looking for barriers — including roads and structures — on their properties that may impact the creeks.
John Murphy, a senior engineering geologist in the State Water Resources Control Board enforcement division, discussed the effort to get regulations in place, which can’t be done within just a few months, and takes time and data.
“At the end of the day, we know that the hitch is in trouble,” and the state wants to do everything they can to protect the fish, he said.
Murphy went over voluntary actions to keep water in the creeks this year, such as reductions in diversions and pumping, coordinating diversion and pumping timing, alternating frost protection methods and pump banks — using groundwater for streamflow. He said they are open to suggestions.
He said they have research going back to the 1950s when the hitch started having trouble.
There are concerns that, even with all of this year’s rains, the storm that took place on Wednesday could be the last rain for months, following a pattern from last year.
Murphy said they have information and momentum to help the fish. “We can’t lose this momentum. We don’t want the hitch going extinct on our watch.”
He said they are early in effort with lots of questions and possible solutions. Murphy added that they can’t let uncertainty about what actions to take lead to the hitch’s extinction.
As for what’s needed from the community, State Water Board staff said they need commitments for specific voluntary actions, such as reducing diversions and pumping from February to May, using alternative frost protection methods, coordinating diversion and pump timing.
They’re also looking for local coordinators, people to share data, leads on connecting with hard-to-reach people and invites to community meetings.
The state wants to hear what people would do to solve the problem in the short and long term, and get input on what specific steps the public thinks it should take.
There will be additional engagement opportunities with the state coming up.
The hitch will be discussed at the Board of Supervisors’ next meeting on Tuesday, Jan. 24, and the State Water Board will hold another listening session from 6 to 8 p.m. Wednesday, Feb. 1, via Zoom, http://bit.ly/CLH_Feb.1.
CLEARLAKE, Calif. — The city of Clearlake’s new recreation center complex received a major show of support and funding on Wednesday.
Congressman Mike Thompson (CA-04) on Wednesday presented a check for $2 million to the city of Clearlake for the Clearlake Burns Valley Sports Complex and Recreation Center project.
This funding was secured in the Fiscal Year 2023 government funding bill.
“The construction of the Burns Valley Sports Complex and Recreation Center will encourage healthier living and stimulate our local economy through youth sports, jobs, increased visitors, and additional hotel room stays,” said Thompson. “I was proud to work with Lake County officials to identify the need for this funding. This project is going to modernize our community, encourage a healthier lifestyle, and boost economic growth for our region.”
“This is a project that will have dramatic and long lasting impacts on our community. Encouraging a healthy lifestyle, safe activities for your youth, and providing a draw for visitors from outside our region are just a few of the benefits of this impact project. We are so grateful for the support of Congressman Thompson and the various agencies that will make this project a reality,” said Mayor Russ Perdock.
The full property will include a small amount of retail space, a new public works corporation yard — which will also serve as the city’s new hub for disaster and emergency response — as well as an 80-unit affordable housing project, and the sports complex and recreation center.
The sports complex will include a new Little League/softball/baseball complex, soccer fields and an approximately 20,000 square foot recreation center.
Thompson represents California’s Fourth Congressional District, which includes all or part of Lake, Napa, Solano, Sonoma and Yolo counties.
Disability representation is slowly increasing in books geared toward children and teens.
In 2019 the Cooperative Children’s Book Center at the University of Wisconsin-Madison – a library that allows teachers, librarians and researchers to view books before deciding which ones to buy – found that only 3.4% of books it received from publishers included a character with a disability.
The CCBC website recently added a diversity statistics book search with categories for physical, cognitive and psychiatric disabilities or conditions. In 2022, the center received 165 books that included a character with a disability, up from 126 in 2019.
As an academic librarian who also has a disability, I’m happy to recommend the following five children’s books that treat disability as a part of life and living.
Moose loves her girl Zara – and she hates saying goodbye. When Zara goes to school, Moose wants to go too and keeps showing up, even though dogs aren’t allowed. What will Zara, her parents, the principal, her teacher and the other kids in Zara’s class do?
This fun picture book is perfect for preschoolers and kindergartners. While Zara uses a wheelchair, her disability isn’t the focus of the story. Readers will have fun seeing what Moose is up to this time and learn that sometimes dogs can go to school.
2. Kelly Fritsch, Anne McGuire, Eduardo Trejos, “We Move Together” (2021)
All bodies are different – whether disabled or nondisabled – and everyone matters. These are the themes of this easy reader. With its vibrant illustrations, simple text and portrayals of a wide variety of people, “We Move Together” is a great introduction to the concepts of community, disability and accessibility for readers in kindergarten through second grade, while older readers can learn more about accessibility and disability rights in the glossary.
3. Darren Lebeuf, Ashley Barron, “My City Speaks” (2021)
A girl who is blind and her dad explore the city and its sounds. They wait at a crosswalk, play in the park, take a bus, avoid a rainstorm and eat ice cream. Words and pictures help the reader feel the rhythms of the city. Readers in preschool through second grade will enjoy this story because of its colorful illustrations and rhythmic text.
Nat Beacon is the new girl in school with a talent for wheelchair racing, but when the 13-year-old gets the chance to audition for a summer production of the musical “Wicked,” she knows the theater is where she belongs. How does she tell her parents?
This novel for readers in fifth, sixth and seventh grades explores themes of independence, friendship and first love.
Daisy and Noah are two of the best musicians in their high school orchestra and dream of attending Juilliard, the prestigious performing arts school in New York City. When their performance of an original piece goes viral, they have to deal with the world’s interpretation of them and their relationship.
This rom-com of a novel combines disability representation with themes of friendship and romance. Great for readers in grades nine to 12.

LUCERNE, Calif. — District 3 Supervisor EJ Crandell is hosting an informational meeting on the plan to turn the Lucerne Hotel into a facility for housing homeless youth.
The meeting will take place from 5:30 to 7 p.m. Friday, Jan. 20, at the Lucerne Alpine Senior Center, 3985 Country Club Drive.
The meeting also will be available via Zoom. The meeting ID is 977 5740 1156, pass code is 589351. One tap mobile: +16694449171,,97757401156#,*589351#.
The grant language stated that the Lake County Office of Education would be the primary partner, and that dozens more local organizations would be secondary partners. However, neither the Office of Education nor other partners said they knew about the application or the plan.
Lake County News has outlined the plan in a series of stories, beginning in December.
The tribe has since threatened legal action against Lake County News for covering the project.
Also in December, the Lucerne Area Town Hall passed a resolution condemning the plan.
Crandell initially only posted the meeting on his own Facebook page before the county of Lake shared it on its Facebook page and sent out an announcement about the meeting.
The meeting’s tentative guests include representatives from the offices of Assemblywoman Cecilia Aguiar-Curry and state Sen. Mike McGuire, and the California Business, Consumer Services Housing Agency.
Confirmed attendees include the Lake County Community Development Department, the Lake County Office of Education, the Scotts Valley Band of Pomo Indians and the Earthways Foundation, the organization that the county sold the Lucerne Hotel to in 2019 over community objections.
A question and answer session also is scheduled.

LAKEPORT, Calif. — Federal funds are helping ensure that the Lake County Sheriff’s Office will have a new headquarters in north Lakeport.
On Wednesday, Rep. Mike Thompson (CA-04) presented a check for $988,600 to the county of Lake for the Lakeport Armory Facility Repurposing Project.
This funding was secured in the Fiscal Year 2023 government funding bill.
A year ago, the county completed a transaction in which it traded a vacant 15.5-acre property at 15837 18th Ave. in Clearlake to the state in exchange for the Lakeport Armory property, located on seven acres at 1431 Hoyt Ave. in north Lakeport next to the Lake County Jail.
The property on 18th Avenue in Clearlake is now being developed for affordable housing.
“Lake County has been significantly impacted by natural disasters and having an efficient and robust response is essential to the safety and well-being of our community,” said Thompson. “I was proud to work with Lake County officials to identify the need for this funding to repurpose the Lakeport Armory as an Emergency Operations Center and help serve the people of the county. This project will help mitigate the risk in Lake County and strengthen our response to wildfires, floods, landslides, and other natural disasters.”
The project began under the tenure of recently retired Sheriff Brian Martin, who aimed to trade the aging sheriff’s office headquarters at 1220 Martin St. for the armory location, where all of the agency’s divisions can be located on the same campus.
Martin was on hand for the Wednesday check presentation, along with his successor, Sheriff Rob Howe.
“I acknowledge that the majority of this project, to date, has been accomplished under recently retired Sheriff Martin. However, as the current sheriff and for those current and future department employees, I would like to express my sincere appreciation for Congressman Thompson’s support of this project. I look forward to continuing the relationship with the Congressman, our Board of Supervisors, County Administration, and all other stakeholders,” said Sheriff Howe. “The idea of a unified sheriff’s department campus that will improve efficiency, response, team cohesiveness, and, ultimately, public safety is very exciting.”
Within the first year, facility rehabilitation improvements may include energy efficiency upgrades — replacement of the HVAC system; roof replacement with solar; weatherization measures — and accessibility alterations.
The planning tasks and initial improvements will assist in repurposing the Lakeport Armory for permanent use by most, if not all, Lake County Sheriff’s Office Divisions and the Emergency Operations Center.
In addition to providing Emergency Operation Services, the repurposed facility will also serve as a Regional Training Center for multiple jurisdictions and public safety disciplines.
As a result, officials said emergency response operations throughout the region will be more resilient, mitigating risks to Lake County and surrounding communities.
All living trusts, at a minimum, have one common denominator: avoiding probate. Beyond that, living trusts are not created equal.
Let us discuss some of the estate planning features that a well drafted living trust often contains.
A well drafted living trust administers a person’s assets during incapacity (prior to death) and at death, without any court supervision (e.g., conservatorships and probate), for the benefit of the settlor who created the trust and his or her loved ones. Flexibility to deal with unforeseen events can be beneficial.
First, a trust should provide for the care of the settlor and the settlor’s loved ones if the settlor is incapacitated.
Does the trust provide authority and instructions for the settlor’s personal care in the event of the settlor’s incapacity?
A trust, as relevant, may say whether the successor trustee pays for in home care services to allow the settlor to remain at home as long as possible; whether the trustee allows an adult child to move in (rent free) to care for the settlor; and whether the trustee pays to relocate the settlor to live with family or at an assisted living facility.
Does the trust contain authority and instructions for the care of the settlor’s dependents if the settlor is incapacitated?
A trust, as relevant, may say whether the trustee pays for all or some of the living expenses of the settlor’s spouse; whether the trustee continues to support an adult child; and whether the trustee continues to care for the settlor’s pets.
Second, a trust should provide a well thought out disposition of the settlor’s trust estate at the settlor’s death.
Does the trust adequately address the varied needs and life circumstances of its beneficiaries?
A well drafted trust often provides discretion to the trustee to administer the trust based on future conditions as they exist at the time of administration.
Does the trust provide the trustee with express instructions or with discretion to use their own judgment to administer the inheritance of a beneficiary who is a minor; to administer the inheritance of a beneficiary who receives needs based government benefits; to administer the inheritance of a beneficiary who has serious creditor problems; or to administer the inheritance of a beneficiary who cannot manage their assets.
A trust, as relevant, may say whether the inheritances of such beneficiaries are subject to further (ongoing) trust management over part or all of their lifetime.
A trust may also allow the trustee to administer a beneficiary’s inheritance to purchase services and/or assets for the health, education, maintenance and support of a beneficiary and without distribution cash to the beneficiary.
Does the trust provide for the proper contingency planning in the event that a named beneficiary does not survive?
A trust should name or describe alternative beneficiaries in the event that a beneficiary is not alive to inherit and provide whether the alternative beneficiary receives their inheritance outright or in further trust.
Does the trust allow the appointment of an alternative successor trustee in the event that all persons nominated in the trust fail to serve as trustee?
A trust can provide a mechanism to appoint an alternative successor trustee without a court petition. That is, the trust may allow the beneficiaries to appoint a trustee or allow a person named as a power holder to appoint a trustee.
Does the trust include, as relevant, properly worded disinheritance and no-contest clauses? A disinheritance clause is particularly relevant when the settlor is not gifting anything to an heir.
Consider a parent who is excluding one or more of their children as beneficiaries. Consider a parent who is making an unequal distribution on their assets amongst their children. Is there a no-contest clause to discourage the less favored children from contesting the unequal distribution of the estate.
The foregoing illustrates how a well drafted living trust may avoid some unforeseen and unintended pitfalls. This is not legal advice. Consult an attorney.

CLEARLAKE, Calif. — Clearlake Animal Control maintained a high release rate in 2022 and now has many dogs for adoption.
At Thursday night’s Clearlake City Council meeting, Clearlake Police Lt. Martin Snyder, who oversees the shelter, reported on the shelter’s statistics for the 2022 calendar year.
He said 389 dogs were taken into the shelter last year.
Of those, 303 have left the shelter. Snyder said those include 169 that went to rescues, 102 that were returned to their owners and 30 were adopted.
Snyder said there were a total of three euthanizations — two for medical reasons and one at the request of an owner.
That leaves the shelter with a 99% release rate, Snyder said.
On Thursday, shelter staff brought “Noah” for a visit to the council. He’s a 3 to 4 year old male American pit bull terrier who is a staff and shelter favorite.
They said he would do well with other dogs and probably cats and he’s neutered and up-to-date on all vaccinations.
Dogs recently adopted include “Snowball,” a male American Staffordshire terrier mix, and “Maya,” a female German shepherd.
There currently are 37 adoptable dogs at the shelter, with staff hoping to find them loving homes.
The shelter is located at 6820 Old Highway 53. It’s open from 9 a.m. to 6 p.m. Tuesday through Saturday.
For more information, call the shelter at 707-762-6227, email This email address is being protected from spambots. You need JavaScript enabled to view it., visit Clearlake Animal Control on Facebook or on the city’s website.

LAKE COUNTY, Calif. — For the foreseeable future, the city of Lakeport’s efforts to annex an area along South Main Street are on hold.
The Lake Local Area Formation Commission, or Lake LAFCo, voted unanimously at its Tuesday morning meeting to terminate the city of Lakeport’s South Lakeport annexation in light of the annexation’s failure to receive a majority vote in the November election.
Executive Officer John Benoit presented the resolution to terminate LAFCo’s proceedings on the annexation.
The area in question includes 50 parcels totaling 137 acres in the area adjacent to South Main Street and Soda Bay Road and east of Highway 29.
It includes what is reported to be the most lucrative commercial corridor in the unincorporated county, which had resulted in years of disagreements between the city and county of Lake before a revenue sharing agreement was created. The Lakeport City Council and Board of Supervisors approved that agreement in January 2022.
The city of Lakeport has had that area in its sphere of influence since the 1980s and for the last several years has been working to formally annex it.
In August 2019, the city filed its application for the annexation with LAFCo, which is tasked with overseeing “orderly development” and protecting natural resources and agricultural lands in Lake County.
However, as the LAFCo process appeared to be moving toward the annexation’s completion last year, there was push back from property owners.
On March 30, LAFCo adopted a resolution approving the proposed annexation subject to the necessary authority proceedings.
In a May proceeding, LAFCo received protests from owners of 16 of the 50 parcels in the annexation area, passing the 25% threshold requiring an election.
That, in turn, triggered an election, which the Lakeport City Council voted in June to consolidate with the general election on Nov. 8.
The annexation was on the ballot as Measure P, and was limited to the 15 registered voters living in the annexation area.
The ballot question read: “Shall the order adopted on March 30, 2022 by the Local Agency Formation Commission of Lake County ordering the annexation to the City of Lakeport of the territory described in that order and designated ‘City of Lakeport Annexation to the City of Lakeport (LAFCo file 2019-0006) (South Lakeport Annexation)’ be confirmed?”
The final election results certified by the Registrar of Voters Office in December showed there were a total of 14 ballots cast, with two ballots, or 14.29%, favoring annexation, and 12 ballots, or 85.71%, opposed. Thirteen of the ballots were cast by mail, and one in person on Election Day.
With Measure P failing to have majority support of the annexation area’s registered voters, it didn’t meet the requirements of a resolution LAFCo approved in May 18 that would have allowed the annexation to move forward.
As a result, Benoit said the next step was to terminate the hearing.
Benoit said no substantially similar annexation proposal for that area can be filed with LAFCo within one year of the adoption of the resolution, unless LAFCo waives that requirement.
“That concludes these proceedings and I can put the box away,” said Benoit, noting a lot of information has been generated in the process.
He said he intended to speak with Lakeport City Manager Kevin Ingram on Thursday and let him know what his options are.
Commissioner Dirk Slooten moved to approve the resolution, with Commissioner Jim Scholz seconding. The commission approved the resolution 7-0.
Later in the meeting, the commission discussed agricultural lands and LAFCo's role, with Benoit noting that LAFCo is concerned about sprawl.
“We don’t like county developments in the sphere of influence of the city,” Benoit said.
LAFCo’s legal counsel, Scott Browne, said a classic example of that problem is the development that happened in the South Lakeport area, where there are urban levels of development without the accompanying level of services.
He said that development should have been done in the city of Lakeport. “Instead we’re now dealing with a real problem.”
Following the meeting, Lake County News reached out to Ingram to ask him about the city’s plan going forward.
“We are looking at various options for the future of the South Lakeport area but I would not say there is a plan,” Ingram said in an email response.
He said the city will work with various agencies — LAFCo, the California Department of Water Resources and the county of Lake — “to better understand the status of things with or without public services.”
Ingram also acknowledged LAFCo’s rule that the city would not be able to submit a formal application again for a year if the city decides to move forward again.

In the blazing upper atmosphere of the Sun, a team of scientists have found new clues that could help predict when and where the Sun’s next flare might explode.
Using data from NASA’s Solar Dynamics Observatory, or SDO, researchers from NorthWest Research Associates, or NWRA, identified small signals in the upper layers of the solar atmosphere, the corona, that can help identify which regions on the Sun are more likely to produce solar flares — energetic bursts of light and particles released from the Sun.
They found that above the regions about to flare, the corona produced small-scale flashes — like small sparklers before the big fireworks.
This information could eventually help improve predictions of flares and space weather storms — the disrupted conditions in space caused by the Sun’s activity.
Space weather can affect Earth in many ways: producing auroras, endangering astronauts, disrupting radio communications, and even causing large electrical blackouts.
Scientists have previously studied how activity in lower layers of the Sun’s atmosphere — such as the photosphere and chromosphere — can indicate impending flare activity in active regions, which are often marked by groups of sunspots, or strong magnetic regions on the surface of the Sun that are darker and cooler compared to their surroundings. The new findings, published in The Astrophysical Journal, add to that picture.
“We can get some very different information in the corona than we get from the photosphere, or ‘surface’ of the Sun,” said KD Leka, lead author on the new study who is also a designated foreign professor at Nagoya University in Japan. “Our results may give us a new marker to distinguish which active regions are likely to flare soon and which will stay quiet over an upcoming period of time.”
For their research, the scientists used a newly created image database of the Sun’s active regions captured by SDO. The publicly available resource, described in a companion paper also in The Astrophysical Journal, combines over eight years of images taken of active regions in ultraviolet and extreme-ultraviolet light.
Led by Karin Dissauer and engineered by Eric L. Wagner, the NWRA team’s new database makes it easier for scientists to use data from the Atmospheric Imaging Assembly, or AIA, on SDO for large statistical studies.
“It's the first time a database like this is readily available for the scientific community, and it will be very useful for studying many topics, not just flare-ready active regions,” Dissauer said.
The NWRA team studied a large sample of active regions from the database, using statistical methods developed by team member Graham Barnes. The analysis revealed small flashes in the corona preceded each flare. These and other new insights will give researchers a better understanding of the physics taking place in these magnetically active regions, with the goal of developing new tools to predict solar flares.
“With this research, we are really starting to dig deeper,” Dissauer said. “Down the road, combining all this information from the surface up through the corona should allow forecasters to make better predictions about when and where solar flares will happen.”

Without strong climate action, forests on every continent will be highly flammable for at least 30 extra days per year by the end of the century – and this fire threat is far greater for some forests including the Amazon, according to our new study.
Our research in Nature Communications looked at 20 years of global satellite data to test the link between wildfires and “vapour pressure deficit” – a measure of the atmosphere’s power to suck moisture out of living and dead plants. It can also be thought of as how “thirsty” the air is.
Our results show that forest fire becomes much more likely above a certain threshold of vapour pressure deficit in many regions. This threshold depends on the type of forest.
Alarmingly, climate change is increasing the number of days the planet passes these crucial thresholds. But by urgently bringing global emissions down, we can minimise the number of extra wildfire days.
fuel: the leaves, branches, twigs and everything else that can catch alight in a forest
fuel moisture: whether fuel is dry enough to burn
ignition: the spark to set things off, such as a lightning strike
weather: conditions such as strong winds and high temperatures, which can aid a fire’s spread.
These four processes act as switches. All must be in the “on” position for a fire to take hold.
The drying out of fuel is particularly crucial for making a forest dangerously flammable. Indeed, manyresearchers are findinglinks between vapour pressure deficit (VPD) and fire activity.
VPD describes the difference between how much moisture is in the air and how much moisture the air can hold when it’s saturated. Once air becomes saturated, water will condense to form clouds or dew on leaves.
Importantly, warmer air can hold more water, which means VPD increases. We refer to the air being “thirsty” when the gap between full and empty air becomes bigger, meaning there’s a greater demand (thirst) for the water to come out of living and dead plant material, drying it out.
This is a serious issue as climate change leads to rising global temperatures.
We then measured the strength of the relationship between VPD and fire activity for different forest types in each continent. And we showed, for the first time, that in many forests there is a strong link between fire activity and VPD on any given day.
Our results show certain VPD thresholds beyond which forest fire becomes more likely than not.
For example, in boreal forests (predominantly northern European and American coniferous forests), this threshold is 0.7-1.4 kilopascals (a unit of pressure). In subtropical and tropical forests such as the Amazon, the threshold rises dramatically to 1.5-4.0 kilopascals. This means the air must be a lot thirstier to spark fire in the tropical forests of Borneo and Sumatra than in the spruce, pine and larch of Canada.
We looked at both low- and high-emissions scenarios and found the risks are much greater if we fail to curb emissions.
If humanity continues to release greenhouse gas emissions unabated, the planet is expected to warm by around 3.7℃ by the end of the century. Under this high-emissions scenario, our study finds there are forests on every continent that will experience at least 30 extra days per year above critical flammability thresholds.
Under a lower-emissions scenario where global warming is limited to around 1.8℃, each continent will still see at least an extra 15 days per year crossing the threshold.
Parts of tropical South America including the Amazon will see the greatest increases in both scenarios by the end of the century: at least 90 additional days in a low-emissions scenario, and at least 150 extra days in a high-emissions scenario.
What are the risks?
Increasing forest fires will have serious consequences. This includes potentially destabilising patterns of fire and regrowth and disrupting the carbon storage we rely on forests for. Indeed, research last year showed the role of the Amazon rainforest as a “carbon sink” (which absorbs more CO₂ that it releases) may already be in decline.
We can also expect increasing harms to human health from wildfire smoke. It is estimated that around the world, more than 330,000 people die each year from smoke inhalation. This number could increase notably by the turn of the century, particularly in the most populated areas of South Asia and East Africa.
Our next research project will explore the links between fire, VPD and climate change in more detail in Australia, our home country. We’re also interested in the forests and regions where VPD doesn’t seem to be the main driver of fire, such as in Japan and Scandinavia.
Our discovery of reliable links between atmospheric dryness and forest fire risk in many regions means we can now develop better fire predictions, at both seasonal and near-term scales. This could bring significant benefits to those on the frontlines of fighting, managing and coexisting with wildfire.

LAKE COUNTY, Calif. — The State Water Resources Control Board staff will hold two public listening sessions in January and February to discuss the emergency situation impacting the Clear Lake hitch and potential near and long-term solutions.
The listening sessions will include presentations from State Water Board staff and opportunities for public input and discussion.
The Clear Lake hitch is a large minnow found only in Clear Lake and its tributaries. Historically, the hitch likely numbered in the millions, but recent surveys indicate a significant decline, and in 2014, California designated the hitch as a threatened species.
The hitch has strong cultural significance for several indigenous Pomo tribes of the Clear Lake region that rely on the hitch, or “chi,” for spiritual purposes and traditions and as a primary food source.
The hitch is also of great importance to the lake’s ecosystem, a significant source of food for other fish, birds and wildlife.
Adult hitch migrate upstream in tributaries of Clear Lake each spring to spawn before returning to the lake. Juvenile hitch hatch in the tributaries and move to the lake as well.
While the hitch’s decline can be linked to a variety of factors including habitat loss, passage barriers, poor water quality, and invasive species, the most immediate threat to their survival is little to no water flowing in Kelsey, Adobe, Manning, Cole and Middle creeks during the upcoming spawning and rearing season, which takes place from February through May.
The State Water Board is looking for ways to protect the Clear Lake hitch now and in the long term, including local voluntary actions to keep water in the creeks this year, obtaining data to better understand the problem and potential solutions, collaboration to fund effective solutions and spread important messages, enforcement to ensure all diversions in the area are legal, and regulations if voluntary actions aren’t successful.
For additional information and updates, visit the State Water Board’s Hitch webpage for continued updates on potential board actions. This website will be updated with related documents and information as available.
