UCCE report: Local forest restoration teams effective at rapid response

Quickly planting trees after wildfires crucial for communities, ecosystems, carbon goals

As the climate crisis fuels more high-severity wildfires, many forests – adapted to bounce back from frequent but less-intense fires – are struggling to recover quickly.

“In a lot of locations, forests in the Sierra Nevada that burn at high severity are not regenerating on their own,” said Susie Kocher, University of California Cooperative Extension forestry and natural resources advisor for the Central Sierra. “They need to have living trees to drop seeds; if everything dies in an intense fire, then there's a high likelihood in those locations that trees might not return for a while.”

According to Kocher, a forest may take multiple decades to grow back on its own, seeding in very slowly from the edges of a burn. To speed up that regeneration process, a pilot program of local “Emergency Forest Restoration Teams,” or EFRTs, have been helping forest landowners rapidly remove dead trees, plant new seedlings and expedite other vital tasks after wildfires.

Kocher is a co-author of a recently released report evaluating the EFRTs, which appear to be effective in assisting often-overwhelmed private landowners navigate competitive funding programs and complicated permitting pathways after wildfire. Small private landowners in California own 7 million acres, comprising 22% of forested land across the state.

“None of our current assistance programs were really designed to rapidly respond to high-severity fire disasters,” Kocher said. “And we're just getting so much more high-severity fire now that there needed to be a different way of helping people, besides business as usual.”

Lead agencies improve coordination of restoration efforts

Drawing from a successful model in Washington, Kocher and other members of the Governor's Forest Management Task Force recommended the formation of EFRTs in 2019 and this recommendation made it into the California Wildfire and Forest Resilience Action Plan of 2021.

Following the Caldor, Dixie and Tamarack fires during that year, disaster relief funds from CAL FIRE and the U.S. Forest Service enabled the establishment of pilot EFRTs in each of the affected regions. A key innovation was designating a local lead agency to coordinate restoration efforts: the El Dorado Resource Conservation District (Caldor), the Feather River Resource Conservation District (Dixie) and Alpine County (Tamarack).

“The idea is that one well-established local agency gets the funds to carry out all the reforestation work,” Kocher said. “They find contractors for the landowners and plan and carry out all the work needed, including dead tree removal, site preparation and replanting; this helps it be more coordinated across the landscape and reduces competition for contractors.”

“Also, for most of that work, there's no cost to the landowner – which is a huge benefit to them, because these things can get really expensive, like many thousands of dollars an acre,” Kocher added.

Although there was an initial steep learning curve for the local lead agencies on the complexities of reforestation and the maze of required permits, they quickly executed a significant number of forest restoration treatments. Within two years, the three pilot teams had collectively completed over 2,500 acres of dead tree removal and 1,400 acres of conifer planting.

“The overwhelming benefit of the pilots was that a lot of work got done on the ground, that otherwise would not have been done – at least not in the timeframe that was made possible by the EFRTs,” said Daylin Wade, a UCCE staff research associate and co-author of the recent report, who synthesized feedback from interviews of professionals involved in the program.

Rapid reforestation better financially, ecologically

Both Wade and Kocher underscored how the EFRTs were crucial in completing restoration tasks in a timely manner. Removal of dead wood becomes trickier and more expensive over time, as the trees decay and are dangerous to cut down.

“A major accomplishment was getting trees out of there while it was both safe and economically viable to remove those trees – and getting trees in the ground before shrubs dominate the site,” Wade explained.

It's also imperative to quickly remove the dead trees to reduce the fuel load and minimize the chances of re-burn in the area.

“If you're not doing this work, then you're actually endangering the investment that you're putting into rebuilding communities that burned, because they're in danger of burning again if you have huge piles of dead trees everywhere,” Kocher said.

Furthermore, expediting those tasks helps restore the forest cover that is crucial for sequestering carbon and achieving the goals of California's sweeping climate action plan – such as attaining carbon neutrality by 2045.

“We have very ambitious carbon goals for our forests in California, and so reestablishing them – even on private lands – is a public benefit,” Kocher said.

Evaluation of EFRTs by UC Cooperative Extension continues

In addition to enumerating the progress of the three EFRT case studies, the evaluation report also lists recommendations to further enhance the program, such as securing rapid and flexible funding for future EFRTs, improving guidance for local lead agencies and streamlining permitting processes.

The authors also stressed the need to expand opportunities for the commercial sale of woody material in the aftermath of a wildfire event. Selling logs and wood chips reduces the volume of material that would need to processed onsite by the EFRTs and their contractors, thereby defraying some of the costs for that work.

But there simply hasn't been a sufficient market for that woody biomass.

“It's a big barrier,” Kocher said. “If we had a healthier timber market, it would be easier to make this stuff pay its own way and be less of a subsidized endeavor.”

UC Cooperative Extension's EFRT evaluation work – made possible by funding from the U.S. Forest Service State, Private and Tribal Forestry, Region 5 – will continue for the next couple years. On the heels of this first report, Wade will next gather and summarize feedback from private landowners on whether the EFRTs are meeting their goals.

And, later this summer and fall, researchers will begin assessing the ecological success of the plantings in the restoration areas, surveying seedling survival and gauging the volume of competing vegetation.

“It's hugely encouraging that we've gotten all these trees in the ground, but it's not the end of the process – it's just the beginning,” Kocher said. “Trees and forests need to be maintained over time, so this next step will let us see how successful that has been, and if there are additional steps needed to actually ensure that these trees succeed and thrive.”

Drought focus of Water Resources IMPACT magazine special issue

UC ANR experts address emotional toll of drought

Preparing the American West for prolonged drought is the focus of a double issue of Water Resources IMPACT magazine. The California Water Commission staff are guest editors for this special open-access edition of the magazine, which is published by the American Water Resources Association.   

Faith Kearns, academic coordinator of University of California Agriculture and Natural Resources' California Institute for Water Resources, is among the authors delving into how drought impacts people and the environment and how we can better prepare for the inevitable. 

The first issue, published on Feb. 14, focuses on water scarcity issues confronting California and the ways these issues affect different sectors. 

In “Trauma, Care, and Solidarity: Addressing the Emotional Toll of Chronic Drought,” Kearns highlights the effects of drought on mental health. She points to the spike in suicide hotline calls when wells ran dry in Southeast Asian communities in California's Central Valley.

By listening to Southeast Asian farmers, Ruth Dahlquist-Willard and Michael Yang of UC Cooperative Extension were able to “lighten the load” for them by providing pragmatic support, Kearns writes.

“The scale of some of these highly emotional issues – drought, wildfires, climate change – can make them seem incredibly difficult, if not impossible, to deal with,” Kearns said. “At the same time, they are affecting everyone living in the western U.S. on a daily basis. I wanted to highlight and provide models based on work that people – whether they are researchers, clinical psychologists, or Cooperative Extension advisors – are doing right now to ease the way.”

The authors who contributed to the double issue are a diverse array of Tribal experts, academics, nongovernmental organization thought-leaders, water managers and water policy influencers, each of whom brings their own perspective on the topic of drought. Their expertise and perspectives in climate science, water policy and water management will help inform drought-related decision-making and support policies that better prepare the state to thrive during periods of prolonged water scarcity.

In addition to Kearns, the first issue includes articles contributed by:

• Samantha Stevenson, University of California, Santa Barbara
• Jay Lund, University of California, Davis
• Ron Goode, North Fork Mono Tribe
• Andy Fecko, Placer County Water Agency
• Jeff Mount, Public Policy Institute of California, and Ted Grantham, University of California, Berkeley/UC Cooperative Extension
• Nat Seavy and Karyn Stockdale, National Audubon Society
• Kjia Rivers, Community Water Center
• Cannon Michael, Bowles Farming
• Michelle Reimers, Turlock Irrigation District

The January/February edition of Water Resources IMPACT magazine can be accessed, free of charge, on the American Water Resources Association website at https://www.awra.org under “Publications.”

The second issue, to be published in March, will focus on drought response, considering the options for adaptation. This two-part series complements the Commission's work on strategies to protect communities and fish and wildlife in the event of a long-term drought.

 

 

Your water-efficient landscape doesn’t have to be barren

UC climate-ready landscape trials identify low-water yet attractive plants

Good news: roses can be a part of your water-efficient landscape. Lorence Oki, UC Cooperative Extension environmental horticulture specialist in the UC Davis Department of Plant Sciences, identified rose cultivars that remain aesthetically pleasing with little water.  

Oki is the principal investigator of the Climate-Ready Landscape Plants project, which may be the largest irrigation trial in the western U.S., and the UC Plant Landscape Irrigation Trials (UCLPIT), the California component of that project. These projects evaluate landscape plants under varying irrigation levels to determine their optimal performance in regions requiring supplemental summer water.

“There are some assumptions that pretty plants use a lot of water, like roses,” Oki said. “Everyone thinks they need a lot of water, but we've found some that don't, and they still look great. A water-efficient landscape doesn't need to look like a Central Valley oak-grassland in the summer. It can look really attractive.”

In 2021, Oki's team at UC Davis identified Lomandra confertifolia ssp. pallida "Pom Pom" Shorty and Rosa "Sprogreatpink" Brick House® Pink as two of the best low-water plants in the trial. 

“The useful tip or information that is shared at the end of each trial is the selection and designation of plants as Blue Ribbon winners. These are the plants that looked good with an overall rating of 4 or higher throughout and were on the low (20%) water treatment,” said Natalie Levy, associate specialist for water resources, who manages the project at the UC ANR South Coast Research and Extension Center.

How plants earn a blue ribbon

Each trial year, the selection of new plants is based on research recommendations and donated submissions from the nursery industry. The landscape plants are trialed in full sun or 50% shade cover.

Irrigation treatments are based on the rate of evaporation and plant transpiration (evapotranspiration) measured through a local California Irrigation Management Information System (CIMIS) weather station that provides a reference evapotranspiration (ETo) rate.

Three levels of irrigation are provided to the plants equal to 20%, 50%, and 80% of ETo. The volume of water applied is the same at each irrigation based on soil characteristics, but the interval between applications varies with weather and the treatment. Using this method, irrigations for the 20% treatment are less frequent than the 80% treatment.

“The 20% treatment during the 2022 trial was irrigated an average of once per month while the 80% treatment was irrigated weekly,” explained Levy.

During the deficit irrigation trial, monthly height and width measurements are taken to determine the plant growth index. Monthly qualitative aesthetic ratings on a scale of 1 to 5 are determined for foliage appearance, flowering abundance, pest tolerance, disease resistance, vigor and overall appearance.

A second round of flowering abundance and overall appearance measurements are also taken to capture more of the blooming period. For example, UCLPIT identified in the 2020 trial at South Coast REC that the "Apricot Drift" rose had a mean overall appearance score of 3.5 out of 5, deeming it “acceptable to very nice” and a low water use plant within the Water Use Classification of Landscape Species or WUCOLS guide.

Project expands options for landscape planting

While attending UC Davis as a master's student, Karrie Reid, retired UCCE environmental horticulture advisor for San Joaquin County, assisted Oki with landscape water conservation research. The landscape plant irrigation assessments were initiated at UC Davis in 2004 and the UCLPIT project, now in its 20^th year, originated from her master's thesis project from 2005 to 2007. A CDFA grant supported duplicating these fields at the South Coast REC in 2017.

“(WUCOLS) only has 3,500 plants in it. There are guesses that there are close to 10,000 cultivars in urban landscapes in California, if not more,” said Oki. “WUCOLS also didn't have numerical ratings. Instead, you'll see verbal ratings like ‘low water use' or ‘high water use.'”

The UCLPIT project has not only developed numerical recommendations for irrigation, but it has also added new landscape plants that are compliant with California's Model Water Efficient Landscape Ordinance. In fact, UCLPIT's data is one of the few sources that can be used to supplement WUCOLS.

Geographic diversity of trial sites adds to knowledge base

In addition to UC Davis and South Coast REC in Irvine, the trials have expanded beyond California as the Climate-Ready Landscape Plants project and is in progress at Oregon State University, University of Washington, University of Arizona and Utah State University thanks to a USDA/CDFA grant awarded in 2020.

Lloyd Nackley, associate professor of nursery production and greenhouse management at Oregon State University, is the principal investigator of the trial in the Portland metro area, which is entering its third year.

“People know that there are drought tolerant plants, but there are many. We're trying to highlight lesser known or newer varieties. And even though the trial is three years, most gardeners would hope that their garden lasts longer than that,” said Nackley.

One of the observations that Nackley recalls is of the Hibiscus Purple Pillar plant. Unlike the trial at South Coast, the Purple Pillar did not perform well in Oregon in the spring.

“It wasn't until August that we saw the plant bloom and begin to look like what we saw from South Coast in April,” Nackley said.

Ursula Schuch, horticulture professor and principal investigator of the trial taking place at the University of Arizona, was also surprised at the range of performance among different plant types and the effects of irrigation, heat and temperature.

“This research will reassure green industry professionals that they can stretch their water budget to successfully cultivate more plants, watering them according to their needs instead of irrigating every plant according to the highest water-using plants,” said Schuch.

Although research is only conducted in the West, the hope is that there will be trials in other regions of U.S.

Doing so would yield comprehensive information about the plants and their performance in different climates. As extreme weather events persist in the U.S., disease pressure and risks do too. Trials throughout the country would provide location-specific data regarding disease susceptibility.
