California's K-12 teachers are being challenged by the Next Generation Science Standards to find new and more engaging ways to teach science. Adopted by California in 2013, the science-education standards guide how science, technology, engineering and math education are delivered to students in the classroom. The Forestry Institute for Teachers (FIT) offers free environmental education training for teachers in a northern California forest.
“Teachers who participate in the Forestry Institute for Teachers learn to apply Next Generation Science Standards concepts as they develop or refine class lessons using the forest as a lens through which all classroom subject matter can be taught,” said Mike De Lasaux, UC Cooperative Extension natural resources advisor for Plumas and Sierra counties and a FIT instructor.
Learning science through FIT's participatory model is more exciting than memorizing facts from a textbook. In the forest, FIT instructors point out opportunities for students to use technology, engineering and math to better understand the world around them. For example, math can be used to estimate the height of a towering tree. Seeing the “web of life” relationships, such as the effects of rainfall and insects on tree growth, leads to more critical thinking to solve problems.
“The goal of the Forestry Institute for Teachers is to provide K-12 teachers with knowledge, skills and tools to effectively teach their students about forest ecology and forest resource management practices and much more,” said De Lasaux.
California teachers from rural and urban settings are invited to spend a week during the summer working outdoors with natural resources experts to gain a deeper understanding of forest ecosystems and human use of natural resources. The participants are organized by grade level for age-appropriate activities. They take field-trips and do hands-on activities such as examining the rings in a tree's cross-section to learn about events – such as wet or dry periods, insect or disease damage – that have occurred during the tree's lifetime.
The Forestry Institute for Teachers has been providing science education and other subject content to California K-12 teachers since 1993 with more than 2,500 educators completing the program.
FIT is a week-long residence program developed by the Northern California Society of American Foresters in collaboration with the University of California Agriculture and Natural Resources' Cooperative Extension, the USDA Forest Service, CALFIRE and other entities. The FIT Program is underwritten by a consortium of public and private sources.
FIT is offered in forested settings in four different Northern California locations:
- June 11-17 in Plumas County
- June 18-24 in Tuolumne County
- July 2-8 in Shasta County
- July 9-15 in Humboldt County
There is an application fee of $25, but training, meals and lodging are free for first-time participants.To watch videos of past participants discussing their FIT experience and to apply to attend, visit www.forestryinstitute.org.
Current wildfire policy can't adequately protect people, homes and ecosystems from the longer, hotter fire seasons climate change is causing, according to a new paper led by the University of Colorado Boulder.
Efforts to extinguish every blaze and reduce the buildup of dead wood and forest undergrowth are becoming increasingly inadequate on their own. Instead, the authors—a team of wildfire experts—urge policymakers and communities to embrace policy reform that will promote adaptation to increasing wildfire and warming.
“Wildfire is catching up to us,” said lead author Tania Schoennagel, a research scientist at CU Boulder's Institute of Arctic and Alpine Research. “We're learning our old tools aren't enough and we need to approach wildfire differently.”
This means accepting wildfire as an inevitable part of the landscape, states the new paper published today in the journal Proceedings of the National Academy of Sciences.
The western U.S. has seen a 2-degrees-Celsius rise in annual average temperature and lengthening of the fire season by almost three months since the 1970s; both elements contribute to what the authors refer to as the “new era of western wildfires.” This pattern of bigger, hotter fires, along with the influx of homes into fire-prone areas—over 2 million since 1990—has made wildfire vastly more costly and dangerous.
“For a long time, we've thought that if we try harder and do better, we can get ahead of wildfire and reduce the risks,” said Schoennagel, who also is an adjunct faculty member in CU Boulder's Geography Department. “We can no longer do that. This is bigger than us and we're going to have to adapt to wildfire rather than the other way around.”
As part of this adaptation process, the authors advocate for actions that may be unpopular, such as allowing more fires to burn largely unimpeded in wildland areas and intentionally setting more fires, or “controlled burns,” to reduce natural fuels like undergrowth in more developed areas. Both these steps would reduce future risk and help ecosystems adapt to increasing wildfire and warming.
They also argue for reforming federal, state and local policies that have the unintended consequence of encouraging people to develop in fire-prone areas. Currently, federal taxpayers pick up the tab for preventing and fighting western wildfires—a cost that has averaged some $2 billion a year in recent years. If states and counties were to bear more of that cost, it would provide incentive to adopt planning efforts and fire-resistant building codes that would reduce risk.
Re-targeting forest thinning efforts is another beneficial reform suggested by the authors. The federal government has spent some $5 billion since 2006 on thinning dense forests and removing fuel from some 7 million hectares (17 million acres) of land, often in remote areas. But these widespread efforts have done little to reduce record-setting fires. Directing thinning projects to particularly high-risk areas, including communities in fire-prone regions and forests in particularly dry areas, would increase adaptation to wildfire, the authors said.
Additionally, as climate change forces species to move their ranges, some may vanish entirely. Familiar landscapes will disappear, a fact that makes many people balk. But such changes, including those caused by wildfire, could be necessary for the environment in the long run, says Max Moritz, University of California Cooperative Extension wildfire specialist and a co-author on the paper.
“We need the foresight to help guide these ecosystems in a healthy direction now so they can adjust in pace with our changing climate,” Moritz said. “That means embracing some changes while we have a window to do so.”
Critical to making a policy of adaptation successful, said Schoennagel, will be education and changing people's perception of wildfire. “We have to learn that wildfire is inevitable, in the same way that droughts and flooding are. We've tried to control fire, but it's not a control we can maintain. Like other natural disasters, we have to learn to adapt.”
How did we get here and where shall we venture together?
This spring, the 100th California Naturalist class is being offered in Sonoma County – the very same county where we first piloted the curriculum. The UC Agriculture and Natural Resources California Naturalist Program is designed to introduce Californians to the wonders of our unique ecology and engage the public in study and stewardship of California's natural communities. The program mission is to foster a diverse community of naturalists and promote stewardship of California's natural resources through education and service. California Naturalist certification courses combine classroom and field experience in science, problem-solving, communication training and community service. Students are taught by an instructor and team of experts who are affiliated with the University of California, local nature-based centers, community colleges, land trusts, or natural resource focused agencies such as California State Parks and cooperating “friends groups.”
What inspired the first California Naturalist class? Georgia, Florida, Texas and 22 other states have Master Naturalist-like programs, so why not California? After all, California is a global biodiversity hotspot filled with nature enthusiasts. It took a volunteer, Julia Fetherston, to get excited about the potential for a California program before our director Adina Merenlender was convinced to attend the 2005 National Master Naturalist Annual Conference in Estes Park, Colo. She was impressed with the impact these programs were having and decided to see what we could do in the Golden State. A good deal of effort followed to advance the cause within UC, secure grant funding, write the California Naturalist Handbook, develop ways to work with organizations across the state, and build a team to run California Naturalist. In 2012, we officially launched the program with five intrepid institutional partners (Santa Rosa Junior College/Pepperwood Foundation, Pacific Grove Museum of Natural History, UC Santa Cruz Arboretum, UC Berkeley Sagehen Creek Field Station, and Santa Barbara Botanical Garden). Four years later California Naturalist received Program of the Year from the national network, the Alliance of Natural Resource Outreach and Service Programs.
The 100th California Naturalist class is being offered at Stewards of the Coast and Redwood this spring. Stewards of the Coast and Redwoods is a non-profit, environmental and interpretive organization that works in partnership with California State Parks in the Russian River Sector of the Sonoma Mendocino Coast District to support volunteer, education and stewardship programs. Participants in this year's spring class have worked hard on a wide range of capstone projects, including multiple wildlife monitoring citizen science projects, improving fish habitat in the watershed, and creating educational materials on ticks, wetland birds, water quality and more. Co-instructors Meghan Walla-Murphy and David Berman have been teaching California Naturalist courses since 2013, first with Occidental Arts and Ecology Center and now with Stewards. Meghan is the author of Fishing on the Russian River and a well-respected wildlife tracker whose workshops are not to be missed. David is an extraordinary environmental educator, watershed expert, and Project Wild facilitator with the Sonoma County Water Agency.
Now that we have 100 classes under our belt, oh, the places we can go! California Naturalist is a community of practice started deliberately with the goal of gaining natural history knowledge. We are working on releasing a citizen science challenge to provide an opportunity for California Naturalists to discover more about California's ecosystems - Discovery!
Surveys show that California Naturalists feel more empowered to address environmental challenges after their training and knowing they can lean on their fellow naturalists. We would like to know more about how California Naturalists are participating in civic engagement. With a new volunteer management system on the horizon, we plan to learn more about the many ways Naturalists are becoming involved in issues that affect their communities. - Action!
In particular, what activities are Naturalists doing that will help communities and natural ecosystems be more resilient to climate change – improving habitat connectivity, restoring riparian areas, or pre/post fire management? We are looking for support to start an advanced training aimed at helping today's climate stewards learn more about climate science and adaptation to support their efforts on climate-wise - Stewardship!
Congratulations to the graduates of the 100th California Naturalist class and all those who went before you.
Have you seen the blaze of super blooms popping up alongside orchards and field crops in our rich agricultural Central Valley? The corridors of poppies, tidy tips, yarrow, baby blue eyes, and redbud planted by farmers, dazzle us with color, but they serve a purpose, too.
The flowers provide nectar and pollen for the pollinators, including honey bees, bumble bees and carpenter bees. Look beyond the buzz, and you'll see other beneficial insects, such as lady beetles (ladybugs) and their larvae devouring aphids, and tiny parasitoid wasps preying on stinkbugs and armyworms. They're (unpaid) pest control agents at work.
Farmers are taking notice. Knowing that most beneficial insects rely on floral resources to survive and reproduce, they're bordering their field crops with strips of flowering plants. In addition to gaining pollination and pest control services, they're gaining financial benefits. University of California researchers documented that pest control and pollination benefits will help pay the cost of a 1,000-foot-long-flowering hedge planting within 7 to 16 years. Their research, Pest Control and Pollination Cost-Benefit Analysis of Hedgerow Restoration in a Simplified Agricultural Landscape, was published last year in the Journal of Economic Entomology.
Other benefits of field edge habitat plantings can include weed exclusion, air quality improvement, erosion reduction, wind protection, shade, and wildlife habitat.
What plants are best to attract beneficial insects to farms and gardens? The UC Statewide Integrated Pest Management Program (UC IPM) has just published a list of insectary plants on its website. The list includes native California perennial flowering shrubs and wildflowers suited for field-edge plantings.
UC IPM defines insectary plants as “those grown to attract, feed, and shelter insect parasites (parasitoids) and predators to enhance biological pest control. Insectary plants provide nectar and pollen for adult natural enemies to consume. Even if pests are abundant, certain natural enemies may be less abundant, shorter-lived, or produce fewer offspring unless nectar and pollen resources are available. Insectary plants can also host alternate prey that will feed the natural enemies and keep them abundant locally.”
Are you concerned about rodents and food safety issues from hedgerows plantings? Not to worry. A recent study by UC Agriculture and Natural Resources (UC ANR) researchers found minimal adverse influence on larger agricultural landscapes. A bonus: Migratory songbirds, like goldfinches, often seek out the seeds from the flowering plants in the hedgerows and offer their own display of color. What about weeds? Yes, they can be problematic. Be sure they're well-controlled before planting wildflowers; think soil solarization and herbicides.
Another UC ANR-associated study, Determinants of Field Edge Habitat Restoration on Farms in California's Sacramento Valley, published this year in the Journal of Environmental Management, found that landowners and farmers familiar with the benefits were more likely to adopt these small-scale habitat restoration plantings on their farms. Also important is technical support from agencies such as the USDA, UC Cooperative Extension Service, and the Xerces Society for Invertebrate Conservation, and the sharing of information from farmer-to-farmer and neighbor-to-neighbor.
Something else we can all do: Share your photos of field-edge habitat plantings and your observations on social media. They tell an important story and can inspire landowners to diversify farmlands. This will help drive home the point that providing flowers for beneficial insects, including bees and natural enemies, will build resilience in our farming systems. Natural pollination and pest control services help counter the disastrous effects of colony collapse disorder and other honey bee maladies, and pesticide resistance.
And it's a counter-punch of color.
To help California forest property owners adapt to the changing climate, UC Agriculture and Natural Resources (UC ANR) has produced a 13-page peer-reviewed paper that outlines actions owners can take to sustain their forests' value even when temperatures rise.
“Managers of forest land have always had to adapt to changing conditions – such as markets, urban encroachment, droughts and floods,” said Susie Kocher, UC Cooperative Extension forestry and natural resources advisor. “We wrote this paper to help forest managers better understand the evolving science of climate change and how they can help their forests adapt to the climate of the future.”
Forests are shaped by the climates in which they grow. The current rapid pace of climate change has not happened for thousands of years, according to climate scientists. Nevertheless, the authors assure forest landowners that there are land management decisions they can make to ensure the resiliency of their resources, and perhaps even improve them.
“Some trees may grow faster under the warmer conditions we experience with climate change,” Kocher said, “especially those at highest elevation where there is adequate precipitation.”
The paper details the solid scientific evidence that indicates the rise in global average temperatures over the past 100 years. The temperatures, it says, “will likely continue to rise in the future, with impacts on natural and human systems.”
The document provides specific recommendations for care of three common types of forest in California: mixed conifer, oak woodland and coastal redwood forests.
Mixed conifer forests – typically composed of white fir, sugar pine, ponderosa pine, incense cedar and California black oak – are susceptible to moisture stress caused by warmer temperatures and reduced snow and rain. The drier conditions make the trees more vulnerable to fire and insect attack.
The drought of 2010-2016 has already had a substantial impact on mixed conifer forests in the Sierra Nevada. Aerial detection surveys show that more than 102 million trees have died since 2010; more than 62 million died in 2016 alone.
The UC ANR climate change adaptation paper suggests reducing competition for water by thinning trees and managing for species and structural diversity. The authors suggest property owners consider the source of seedlings when planting new trees.
“Select seedlings adapted to a slightly lower elevation or latitude than your property,” Kocher said. “These would be more likely to thrive under the 3- to 5-degree warmer temperatures we expect in 50 years or so.”
Oak woodlands are widely distributed and diverse in California, which gives them moderate to high capacity to adapt to climate change. Mature oaks are more resilient than young trees and seedlings.
One potential impact of climate change on oak woodlands is increasing precipitation variability and increasing spring rains. The moisture change could increase the spread and prevalence of Sudden Oak Death (SOD), a disease caused by a bacterium that was introduced into California from outside the U.S. SOD is primarily a concern in areas with tanoaks in Central to Northern California coastal areas.
“To reduce the spread of sudden oak death, land owners should prevent the movement of infected leaves, wood and soil,” according to the paper.
The primary concern for coastal redwood forests is the decline in fog. Fog frequency in coastal redwoods is 33 percent lower now compared to the early 20th Century. Less fog and rain plus warmer temperatures would leave coastal areas where redwoods typically thrive drier. But that doesn't mean redwoods will disappear. Areas with deep soil and areas close to streams and rivers may provide refuge for redwood forests.
The new publication, Adapting Forests to Climate Change, can be downloaded free from the UC ANR Catalog. It is the 25th in the Forest Stewardship series, developed to help forest landowners in California learn how to manage their land. It was written by Adrienne Marshall, a doctoral student at the University of Idaho; Susie Kocher, UC Cooperative Extension forestry and natural resources advisor; Amber Kerr, postdoctoral scholar with the UC John Muir Institute of the Environment; and Peter Stine, U.S. Forest Service.
