Deadly Bat Fungus Detected in California

The fungus that causes White-nose Syndrome (WNS), a deadly disease of bats, has been detected in low levels in California for the first time. Fungal DNA of Pseudogymnoascus destructans (Pd) was detected in samples collected this spring from bats on private land in the Plumas County town of Chester. The California Department of Fish and Wildlife (CDFW) and U.S. Fish and Wildlife Service (FWS) have been preparing for possible detection of the fungus with partner organizations since 2009. While there is currently no indication the disease itself is affecting bat populations in California, the lab tests suggest Pd is here.

WNS awakens bats during hibernation, causing them to use energy reserves needed to survive winter, when insects they rely upon for food are not available. The fungus was first detected in New York in 2006 and spread incrementally. Bats that have contracted the disease have now been confirmed in 33 states and seven Canadian provinces. Including the recent California discovery, the fungus alone has now been detected in a total of five states.

WNS has killed millions of bats in the U.S., including more than 90 percent of the bats in some hibernation colonies. Since bats usually produce only one offspring per year, it could take decades for some populations to recover from a major die-off.

“WNS is considered one of the deadliest wildlife diseases, having killed over six million North American bats since it was discovered,” said CDFW Wildlife Veterinarian and Epidemiologist Dr. Deana Clifford. “WNS doesn’t affect human health or pets, but the ecological impacts of bat die-offs may indirectly impact agricultural systems through loss of the natural pesticide effect and nutrient cycling of bats.”

Until spring 2016, the westernmost occurrence of Pd was in eastern Nebraska. In March of that year WNS was confirmed in Washington State—1,300 miles west of the nearest known location of the fungus. How it got there is unknown; Pd spreads through physical contact with an infected bat or Pd in the environment. Because spores are persistent, people can also spread the fungus from infected areas to non-infected areas on their shoes, clothes or gear.

Surveillance for WNS has been supported by a national program administered by the U.S. Geological Survey (USGS) National Wildlife Health Center in Wisconsin in collaboration with FWS, Northern Arizona University (NAU), and Bat Conservation International (BCI). CDFW has worked with the National Park Service Klamath Network (NPS KLMN) and others to collect swab samples from bats around California since 2016. The samples tested for the DNA signature of Pd were negative until 2018, when one sample from a little brown bat maternity colony in Chester suggested the fungus may be present at low levels. In 2019, the same site and another in Chester yielded three bats with similar low-level detections.

Dr. Alice Chung-MacCoubrey of the NPS KLMN, who led the surveillance work at Chester and several other northern California sites, said, “The detection of Pd at Chester, even at these low levels, is troubling. It has now been detected in two successive years at two different sites and with testing by both the NWHC lab and the NAU lab. In other parts of North America affected by WNS, low-level Pd detections preceded detection of the disease itself by one to four years.”

“Detection of Pd at the levels reported in Chester are possible thanks to advanced tools and surveillance networks in place today that we did not have in the years right after WNS was discovered,” said Jeremy Coleman, National White-nose Syndrome coordinator for the FWS, which leads the national response to the disease. “These very early indications that Pd is present allow for a more proactive response by local partners than what has been possible before. Just how long we’ll have before WNS emerges in California’s bats is a big unknown.”

CDFW leads the California WNS Steering Committee, a multi-agency scientific research group that has been monitoring WNS nationally since 2009. The Committee includes the FWS, NPS, U.S. Forest Service, USGS, BCI, California State Parks, U.S. Department of Defense and National Speleological Society (NSS). They developed a WNS response plan for California that outlines actions to be taken if the fungus or disease arrives in California.

“It is critically important for CDFW and our partners to follow up on these detections,” said CDFW Wildlife Ecologist Dr. Scott Osborn. “In the coming months and years, we will intensify surveillance for WNS, monitor impacts on bat populations, and assist with research on disease management. We hope disease treatment and prevention techniques currently in development will be available soon.”

Meanwhile, Osborn asks all Californians to be vigilant and cooperate with management actions that may be taken to slow the spread of WNS. People can assist with surveillance by reporting unusual behavior they see in bats. Sick or dying bats observed during winter in the colder regions of the state should be reported to CDFW at www.wildlife.ca.gov/conservation/laboratories/wildlife-investigations/monitoring/wns/report.

According to Osborn, caving organizations like the NSS have helped collect important information about California’s underground bat roosts. People who enter caves and mines should follow decontamination protocols at www.whitenosesyndrome.org/static-page/decontamination-information, and do not transfer clothing or gear between certain sites.

CDFW Celebrates Earth Day

Monday, April 22 is the 49th annual Earth Day and the 2019 theme is “Protect Our Species.” The California Department of Fish and Wildlife (CDFW) works to protect our state’s native species every day of every year.

CDFW performs and oversees wildlife habitat conservation and restoration to maintain healthy ecosystems throughout the state. No matter where a native plant, fish or animal lives—in a marine, brackish or fresh water environment, on land, in trees or underground—all living things need clean, healthy habitats.

Some people see a wetland, grassland, desert or any undeveloped landscape and think, “There’s nothing there.” But there are numerous plant, animal and fish species living there, hidden underwater, underground, under rocks and in rock crevices. Those “unused” spaces are home to many species that are part of the elaborate web of life on which all living things depend.

In the past, people thought natural resources—like fresh, potable water—were unlimited. We know better now, yet still produce millions of tons of garbage each year and often dispose of it in ways that harm wildlife. With more than seven billion people on the planet, such a careless lifestyle causes irreparable damage to the very ecosystems all forms of life need to live.

It’s easy to reduce, reuse and recycle the products we use each day. And when we do, our behavior benefits wildlife as much as it does ourselves.

Californians have been celebrating Earth Day with festivals, learning opportunities, and activities such as trail and habitat clean-up and restoration since 1970. It’s a day to think about how each of us affects our world’s limited natural resources, and what we can do as individuals or as groups to tread lightly on the Earth, make up for past damage and restore what we can.

For links to environmentally healthy living suggestions, Earth Day festivals and other activities throughout California, please visit CalRecycle’s Earth Day webpage.

CDFW staff will participate in Earth Day activities around the state, and would be pleased to discuss ways we can conserve wildlife with you at any of these events.

Time’s Running Out for Your Tax Return and Endangered Wildlife

The deadline is looming… how many days left until April 15? Never enough. But you’ll get it done. And when you do, you can support California’s rare, threatened and endangered wildlife species. As you near the end of your California Individual Income Tax Form 540, look for the Voluntary Contributions section. Enter any amount you would like to donate to the California Sea Otter Fund (line 410) and/or the Rare and Endangered Species Preservation Program (line 403).

Any amount you contribute will support state programs that benefit California species at risk of extinction. For most people, donations are tax-deductible the following year.

The Rare and Endangered Species Preservation Program (RESP), has funded work benefiting California’s native at-risk plants, wildlife and fish since 1983. California taxpayers’ donations to this fund have enabled CDFW to obtain grant money from the federal government and collaborate with many other organizations to conserve native wildlife.

For example, CDFW is currently working on projects to save San Francisco garter snakes, tricolored blackbirds, salamanders, mountain yellow-legged frogs, Mohave ground squirrels and California condors.

Last year, the RESP voluntary donations helped provide endangered species protection for the tiny coast yellow leptosiphon (Leptosiphon croceus), which is only known to exist in San Mateo County; the beautiful Lassics lupine (Lupinus constancei), known from only two populations in the remote Lassics mountains of Humboldt and Trinity counties; the uniquely colonial tricolored blackbird (Agelaius tricolor), which is restricted almost entirely to California; and the Humboldt marten (Martes caurina humboldtensis), a small forest carnivore.

Contributions to the California Sea Otter Fund are split between the California Department of Fish and Wildlife (CDFW) and the State Coastal Conservancy to benefit our Southern sea otter (Enhydra lutris nereis) population. The smallest marine mammal once lived in nearshore waters all along California’s coast and in estuaries such as Humboldt, Tomales, San Francisco and Morro bays. Now only 3,000 sea otters occupy a much smaller range. They are protected by the federal Endangered Species Act, Marine Mammal Protection Act and state regulations.

CDFW uses Sea Otter Fund donations for scientific research on the causes of death in California’s sea otters to help inform management actions to protect them.

The Coastal Conservancy uses most of your donations for grants supporting research and conservation actions that facilitate sea otter recovery. Some of that research has investigated factors limiting population growth and opportunities for range expansion to facilitate population recovery.

If someone else prepares your state tax return, please let him or her know you want to donate to the Rare and Endangered Species Preservation Program on line 403 and/or the California Sea Otter Fund on line 410. If you use TurboTax, step-by-step instructions to help you find the California Contribution Funds are posted on the CDFW website.

CDFW biologists have achieved important recovery milestones and protected vulnerable species, thanks to California taxpayers. More information about how CDFW uses donated funds is at www.wildlife.ca.gov/tax-donation and at www.facebook.com/seaotterfundcdfw.

Wildlife Conservation Board Funds Environmental Improvement and Acquisition Projects

At its March 7 quarterly meeting, the Wildlife Conservation Board (WCB) approved approximately $8 million in grants to help restore and protect fish and wildlife habitat throughout California. Some of the 21 approved projects will benefit fish and wildlife — including some endangered species — while others will provide public access to important natural resources. Several projects will also demonstrate the importance of protecting working landscapes that integrate economic, social and environmental stewardship practices beneficial to the environment, landowners and the local community.

Funding for these projects comes from a combination of sources including the Habitat Conservation Fund and bond measures approved by voters to help preserve and protect California’s natural resources.

Funded projects include:

  • A $680,000 acquisition in fee of approximately 32 acres of land as an expansion to the California Department of Fish and Wildlife (CDFW) Battle Creek Wildlife Area for the protection of terrestrial and aquatic habitats supporting salmonid species, to enhance habitat linkages and connectivity, and to provide future wildlife-oriented public use opportunities near Anderson in Shasta County.
  • A $440,000 grant to CDFW for a cooperative project with California State Parks to improve the parking lot, provide an ADA-accessible viewing platform, and install a new ADA-accessible toilet at North Table Mountain Ecological Reserve, eight miles north of the Oroville, in Butte County.
  • $1.3 million for two grants to The Trust for Public Land to acquire approximately 1,415 acres of land for the protection of threatened and endangered species, preservation of desert springs with year-round surface water and a riparian corridor, and provide future wildlife-oriented public use opportunities near Lake Isabella in Kern County.
  • Two grants for a total of $480,000 to the Transition Habitat Conservancy to acquire in fee approximately 120 acres of land from two separate owners for the protection of deer and mountain lion habitat, to maintain a migration corridor for the deer herd, and to provide future wildlife-oriented public use opportunities in the hills northwest of Portal Ridge, in Los Angeles County.
  • A $757,000 grant to the Natural Communities Coalition for a cooperative project with CDFW, Orange County Parks and California State Parks in Crystal Cove State Park and Laguna Coast Wilderness Park – both in Orange County. The project will construct 16 seasonal pools and restore approximately 15 acres of adjacent upland coastal sage and cactus scrub habitat that will provide breeding and foraging habitat for the western spadefoot toad.

Tax Time is the Right Time to Help California’s Endangered Wildlife

As you gather your W-2 and other income tax paperwork, the California Department of Fish and Wildlife (CDFW) hopes you will consider helping our state’s endangered plants, animals and fish when you file your state return.

The California Individual Income Tax Form 540 gives us all an opportunity to help our native wildlife—including plants and fish—by donating to the Rare and Endangered Species Preservation Program and the California Sea Otter Fund in the Voluntary Contributions section of your state return. Any amount you contribute will support programs that benefit California species at risk of extinction. For most people, donations are tax-deductible the following year.

We live and work in one of the most biologically and geographically diverse states in North America—one reason California is such a nice place to live. But it is also the state with the largest human population, and many of our activities are detrimental to wildlife.

California has 220 plant species and 87 animal species listed as rare, threatened or endangered. Money raised through the tax contribution program helps pay for essential CDFW research and recovery efforts for these plants and animals, as well as critical efforts to restore and conserve their habitat. Habitat conservation and restoration for the most vulnerable species also protects many other plants and animals, helps recover ecosystem function and enhances the outdoor experience for all Californians.

The Rare and Endangered Species Preservation Program (RESP) on line 403 of yourtax return, has supported work benefiting California’s native at-risk fish, wildlife and plants since 1983. Donations to this fund by California taxpayers has enabled CDFW to obtain grant money from the federal government and collaborate with numerous stakeholders, agencies and other organizations to conserve native wildlife.

For example, with such partners we are currently:

  • investigating the impact that a deadly new fungus may have on native salamanders and ways to potentially manage infections,
  • reintroducing critically endangered mountain yellow-legged frogs to historically occupied areas,
  • assisting with development of a 10-year Recovery Action Plan for the San Francisco gartersnake and plans for future reintroductions,
  • investigating the impacts of insecticides on food resources, and breeding success of the threatened tricolored blackbird,
  • assisting with Mohave ground squirrel population monitoring at a long-term monitoring site near the Coso Range of Inyo county, and
  • coordinating development of a plan for the release of California condors into the Klamath region of northern California to help increase the breeding population and species distribution.

In 2018, the RESP voluntary donations helped provide endangered species protection for two species of plants, one bird and one mammal at risk of extinction: the tiny coast yellow leptosiphon (Leptosiphon croceus), known from only one population in San Mateo County; the beautiful Lassics lupine (Lupinus constancei), known from only two populations in the remote Lassics mountains of Humboldt and Trinity counties; the uniquely colonial tricolored blackbird (Agelaius tricolor), which is restricted almost entirely to California; and a small forest carnivore, the Humboldt marten (Martes caurina humboldtensis).

The RESP donations are also helping biologists evaluate whether two species of frogs warrant protection under the California Endangered Species Act.

Contributions to the California Sea Otter Fund on line 410 of your tax return are split between CDFW and the State Coastal Conservancy to benefit our Southern sea otter (Enhydra lutris nereis) population. The smallest marine mammal once lived in nearshore waters all along California’s coast and in estuaries such as Humboldt, San Francisco, Tomales and Morro bays. Reliable sources estimate there once were as many as 16,000 sea otters in California before fur traders hunted them to near-extinction in the 19th century. A few survived, were discovered in the 1930s, and quickly given legal protection. They are federally listed as threatened.

The Coastal Conservancy uses most of your donations for grants supporting research and conservation actions that facilitate recovery of California’s sea otter.  Research funded through this program has investigated factors limiting population growth and opportunities for range expansion to facilitate population recovery. Conservation actions funded have reduced threats to sea otters including:

  • reducing cyanobacteria blooms affecting otters, through management of water chemistry at Pinto Lake in Watsonville,
  • reducing vehicle strikes on otters, through installation of speed humps and signage on a coastal road in Moss Landing, and
  • reducing disturbance to sea otters by marine recreationists, through the Sea Otter Savvy

CDFW uses Sea Otter Fund donations for scientific research on the causes of death in California’s sea otters to help inform management actions like those listed above.

More than 16 million Californians file state tax returns each year. If each one donated just one dollar, we could solve many problems for our wildlife and ecosystems. It doesn’t take a large donation (although we dearly appreciate those!) to make a difference. The average voluntary contribution in 2018 was $15.

CDFW biologists have achieved important recovery milestones and protected vulnerable species, thanks to California taxpayers. More information about how CDFW uses donated funds is at www.wildlife.ca.gov/tax-donation and at www.facebook.com/seaotterfundcdfw.

If someone else prepares your state tax return, please let him or her know you want to donate to the Rare and Endangered Species Preservation Program on line 403 or the California Sea Otter Fund on line 410. If you use TurboTax, step-by-step instructions to help you find the California Contribution Funds are posted in the CDFW Document Library.
