Taking aim at wildfires in w88 casino

With wildland fires eating up the forests and rangelands of w88 casino each summer and fire season now upon us, University of w88 casino, Reno scientists in the College of Agriculture, Biotechnology & Natural Resources are examining how drought, climate change and land management will affect future fire activity and how fires can in turn influence plant, soil and hydrologic processes.

In 2016, a little over 265,000acresstatewide in w88 casino burnedfromwildfires. In 2017, around 1.3 millionacres burned, and in 2018, a little over a millionacres burned, according to the National InteragencyFireCenter in Boise, Idaho. They reported, in 2019, 562 fires burned 82,282 acres in w88 casino, with 318 human-caused fires burning 18,801 acres and 244 lightning fires burning 63,481 acres.

As part of national and statewide initiatives, the University scientists are working to understand what drives increases in w88 casino frequency, size and severity; how fires are changing ecosystem function in forests and rangelands; and what management actions can help reduce the negative ecological and economic impacts of w88 casino.

“Our college faculty have for years been at the forefront of teaching, research, and Extension regarding rangeland, woodland and forest fires,” said Bill Payne, dean of the College of Agriculture, Biotechnology & Natural Resource at the University. “In recent years we have added numerous new faculty with expertise in different aspects of w88 casino ecology, and we seek to integrate research, teaching, and Extension with a view towards greater knowledge, better policy prescriptions and improved, adaptive management practices.

“For example, the Experiment Station, led by Chris Pritsos, is funding at least five research projects on w88 casino at the amount of 0,000, and our faculty have been very successful at attracting more than .25 million in extra-mural funding to fund research and Extension related to w88 casino ecology and preparedness. We have a great many partners towards this end, including federal and state agencies, other colleges within the University; other universities; federal, state and local firefighters; and dozens of individual communities.”

One of the College’s longstanding outreach programs, Living With w88 casino, a collaborative effort among federal, state and local firefighting and resource management agencies, is managed by the University of w88 casino, Reno Extension.

“There isn’t just one approach to protect wildlands and promote quicker recovery from fires; it’s definitely a multi-faceted approach,” Christina Restaino, director of the Living With w88 casino Program and an assistant professor in the College of Agriculture, Biotechnology & Natural Resources, said.

As a natural resource specialist w88 casino College’s Extension unit, Restaino works with other entities across the state to provide education on how to prepare for and mitigate the detrimental effects of wildfire.

&w88 casino;It requires that we, at minimum, work together to achieve the three principles of the National Cohesive Strategy, which are: w88 casino Adapted Communities, Safe and Effective Response, and Resilient Landscapes.”

In w88 casino, land management agencies have signed onto a shared stewardship agreement and have adopted the w88 casino Cohesive Strategy as a guidepost for w88 casino management throughout the region.

“We can’t separate humans from the landscape, so we need to be working to build resilient landscapes to w88 casino through treatments like the BLM and USFS are doing,” Restaino said. “We need to build capacity for firefighting response and proactive fuels treatments, and we need to have communities in the Wildland Urban Interface become adapted to w88 casino through good defensible space, safe places for firefighters to fight w88 casino and evacuation preparedness.”

Restaino’s emphasis is on wildland w88 casino science, forestry and natural resource management. Her research has looked at the intersection of land management and forest resilience to w88 casino, drought and climate change. She has worked extensively in science outreach and communication, translating ecological principles to resource management and forest and w88 casino policy. She focuses on translating scientific information for use in land management and helping to inform the public about pressing ecological issues.

“We work alongside our agency and local fire protection district partners to get peer-reviewed science-based recommendations to residents of w88 casino about preparing for wildfire,” she said. “Fire management agencies in w88 casino are constantly engaging with scientists to make science-based land management decisions.”

Their annual w88 casino program, w88 casino Wildfire Awareness Month is May, this year during a time when everyone is trying to set health boundaries through social distancing and staying at home.

&w88 casino;Wildfires can and will still happen this year, even though people are all locked down at home,” Restaino said.

Erin Hanan

One of those scientists is Erin Hanan, a w88 casino ecologist and assistant professor in the College’s Department of Natural Resources & Environmental Science. Her research focuses on how climate change and management affect wildfire activity in the western U.S. and how shifting w88 casino regimes affect ecosystem processes.

“In recent years, the world has experienced several record-setting wildfires,” she said. “As the frequency of these disasters increases, we need strategies for managing risk. However, our success will depend upon why wildfire activity is increasing in the first place and what factors influence w88 casino behavior at the scales where management is implemented.”

We know that climate change and historical w88 casino suppression are two major factors that are leading to more severe wildfires; though until recently, we’ve only been able to attribute the relative role of these drivers at large scales,” she said.

Hanan, who runs the w88 casino and Dryland Ecosystems Lab at the University, also conducts research as part of the College’s Experiment Station and has been modeling the extent to which climate change and fuel accumulation promote the spread of severe fires in western U.S. watersheds and which drivers dominate at the scale of actionable w88 casino.

“We are finding that the effects of climate change and fuels can vary at fine scales within watersheds, so potential w88 casino strategies need to be evaluated in the context of local environmental conditions,” she said.

Recovery from wildfires

Hanan is also working on modeling how quickly ecosystems recover from wildfire, which can range from years to many decades or longer.

&w88 casino;I’m working to forecast how quickly ecosystems recover and how long it takes for the risk of severe wildfire returns in different western U.S. watersheds,” she said. &w88 casino;Preliminary results show that climate warming can increase the rate of recovery in wet regions while slowing recovery in drier ones, even within the same watershed.

In another project, she is collaborating with the Forest Service’s Fire Behavior Assessment Team and Jonathan Greenberg, an associate professor also in the College’s Department of Natural Resources & Environmental Science, to work in the path of advancing wildfires in the Sierra w88 casino.

Their team goes into the field with firefighters to take measurements and inventory plants and soils. Once the w88 casino passes through, the team returns to measure its effects.

“We are using temperature sensors installed at different depths in the soil profile to examine how w88 casino intensity influences carbon and nitrogen cycling and how ecosystem responses to w88 casino vary along environmental gradients such as soil moisture, vegetation and elevation gradients,” Hanan said.

Preventing catastrophic wildfires

&w88 casino;We have known for many years that fires in the Great Basin are becoming more frequent, larger, and more destructive, and that the direct, rehabilitation and additional miscellaneous costs are getting increasingly out of control,” Payne, dean of the College, said. &w88 casino;The ecological costs are also staggering whether reduced critical habitat, loss of biodiversity, increased invasive species, soil degradation, or altered hydrology. Many economic activities vital to rural communities, including ranching, mining, hunting, fishing and recreation, are also adversely affected.”

As far as preventing catastrophic wildfires, experts agree there is no one-size-fits-all approach. Authors of the U.S. Fourth National w88 casino Assessment contend that w88 casino warming has increased wildfire severity, and the likelihood of catastrophic fires will continue to increase unless aggressive action is taken to mitigate greenhouse gas production.

There are several w88 casino activities that are designed to reduce the occurrence of catastrophic wildfires, such as controlled burns or forest thinning, and legislatures have appropriated a lot of funding to these activities.

“Fuel reduction activities can be very effective in areas with unnaturally high fuel loads, such as in low-elevation pine forests that have experienced extensive w88 casino suppression,” Hanan said. “In the southwestern United States, for example, climate conditions are frequently conducive to w88 casino and so fuel load is the main limiting factor.”

“In other regions however, w88 casino activity is mostly driven by climate conditions and fuel aridity,” she said. “In these systems, fuels grow rapidly and therefore fuel reduction is not a feasible approach for reducing wildfire risk over large areas.

“In wet systems like the Pacific Northwest, fuel loads are naturally high and w88 casino is infrequent because the forests are usually too humid to burn. In these environments, thinning is not likely to be beneficial because extreme fires in the region are more limited by moisture and flammability than they are by fuel load. In these areas, climate change is increasing aridity, which in turn increases the occurrence of catastrophic fires.”

w88 casino and silviculture

Sarah Bisbing specializes in w88 casino ecology, silviculture (the care and development of forests), w88 casino stand dynamics, w88 casino landscape genetics and global change ecology. She is a w88 casino ecology assistant professor and researcher from the College’s Department Natural Resources & Environmental Science who also conducts research as part of the College’s Experiment Station.

With a multitude of factors – such as catastrophic wildfires – affecting stresses to forests and rangelands, Bisbing steered her research to find solutions to mitigate impacts on the ecological, economic and social services provided by w88 casino ecosystems.

Leading a team of scientists and forest managers, Bisbing is conducting a Sierra w88 casino-wide study, the Sierra w88 casino Adaptive Management Experiment, known as AMEX, to identify alternative forest management treatments that will improve conifer forest resistance and resilience to climate change. It is a multi-agency project that stretches the length of the Sierra w88 casino with forest research plots in varying elevations.

This long-term, multi-decade study will compare treatments representing fundamentally different climate change impact scenarios and a suite of potential approaches w88 casino managers may take to mitigate impacts on the ecological, economic and social services provided by w88 casino ecosystems.

The study was designed by Bisbing and Professors Rob York and Rick Satomi of U.C. Berkeley. It is based on the national Adaptive Silviculture for Climate Change program led by Linda Nagel at Colorado State University. Project collaborators include Jim Kral and Jason Poburko of the California Department of Forestry and w88 casino Protection and Eric Knapp and Malcolm North of the U.S.D.A. Pacific Southwest Research Station.

w88 casino health treatments

Forest health improvement treatment types are defined as resilience, resistance and transition treatments and include fuels reduction, pest w88 casino, biomass utilization and reforestation coupled with mechanical treatments to provide diversity in species, age classes and structures at the landscape and regional scales.

Resilience treatments closely mimic forest structure under historic w88 casino conditions and are designed to prepare the forest for disturbance by creating tree stand conditions that will help recovery of pre-disturbance composition and structure.

Resistance treatments are aimed at reducing fuel loading and will prepare the forest to resist a disturbance by creating stand structure that is open and park-like and forces w88 casino to stay on the ground.

Transition treatments will help the w88 casino adapt to changing climate, representing the scenario where resistance and resilience treatments are not effective and the w88 casino cannot recover without intervention. Treatments mimic a disturbance that fundamentally changes the composition and structure of the w88 casino, requiring foresters to plant species better adapted to the new conditions of the climate change-impacted system.

&w88 casino;This research will help inform what forest managers will do in the long run to increase carbon sequestration, combat drought mortality and make forests more resistant and resilient to catastrophic wildfires and insect damage,” Bisbing said. &w88 casino;Climate change is and will be increasing the severity of ecological disturbances in forests, which will not only have devastating impacts on forest ecosystems but also turn these carbon sinks to carbon sources, leading to increases in the release of carbon into the atmosphere. This study will guide forest managers as they build resilience and resistance to those disturbances and attempt to mitigate the impacts of climate change on forest ecosystems.”

Now, without fires, there is a buildup of fuel. Couple that with warmer temperatures and dried out vegetation because of climate change, along with more communities being built in forested areas, and all the main components that lead to wildfires are in place across the West.&w88 casino;

Teaching the experts

Knowing how to care for w88 casino's land before and after it is affected by fire and other disturbances is a key to reducing wildland fire risk and repairing lands after a fire.

Fire operations managers, such as those in the Bureau of Land Management in w88 casino that sustains lands, water and wildlife, work to change how fire behaves to protect w88 casino’s rangelands. They look to science to help guide them.

A partnership in the spring of 2019 between the BLM and the University of w88 casino, Reno created an educational endeavor called the Rangeland Ecology & Management Program. Program classes include Rangeland Vegetation Measurements, Soil Science, Range & Forest Plants, and Wildlife Ecology & Management courses, among others.

"What's better to teach w88 casino land issues than the University of w88 casino, Reno," Paul Petersen, BLMs w88 casino State Fire Management Officer, said. "It already has a large knowledge base of Great Basin and w88 casino issues, climatology and range types. And it's a great opportunity to partner with a land-grant university. We're a land management agency."

Professor Tamzen Stringhamandrangeland ecologist Devon Snyder, both in the College’s Department of Agriculture, Veterinary & Rangeland Sciences who also conduct research as part of the Experiment Station, put the curriculum together for the program. They taught the program’s first course, Rangeland Resource Management, at the Bureau’s office in Carson City to wildland firefighters. Most worked right here in w88 casino. All were from a federal agency fire program, some in neighboring states.

"We had 36 students, and all were professional and highly engaged," Stringham said.

All studied the changes that happen over time on and below the Earth's surface; how soil develops; how to identify plants; how soil, w88 casino and plants interact to form ecosystems; and how arid-land ecosystems respond to disturbance events.

While programs for specialists who work in forested areas already existed, a training for arid-land professionals didn't. The training Petersen had asked Stringham to develop was a novel one.

"This is the first one that's focused on Great Basin and high-desert ecology and w88 casino ecology, which is important for our firefighters because that's where they work," Petersen said. "We're really excited about this partnership."

w88 casino in forests and rangeland is generally very different, but the reliance on science is necessary for both.

Great Basin w88 casino Exchange

The Great Basin's unique sagebrush-steppe ecosystem is in decline due to a variety of factors, such as invasive species, piñon and juniper tree encroachment and expansion, multiple anthropogenic uses, w88 casino and severe wildfire. All of these factors are threatening grasslands and shrublands globally.

To keep scientists and land managers connected, the Great Basin Fire Exchange, based at the University of w88 casino, Reno, works to facilitate the flow of the latest science and science needs to the fire, fuels and restoration science and management community.

“The main way we connect scientists and land managers is through our activities - field workshops, webinars, in-person trainings and online courses,” said Génie MontBlanc, manager of the w88 casino Exchange, and faculty in the College of Science. “And we receive consistent positive feedback about our monthly newsletter that has almost 900 researcher and manager subscribers. People also reach out to me directly to ask questions, and I connect them to experts who can help them answer their questions.

&w88 casino;Managers need the latest information and tools to address the most important issues in the Great Basin. And yes, land managers apply the latest information and tools on the ground, to the extent that they are applicable to their particular challenges.”

Those w88 casino challenges include:

• Fuels and vegetation w88 casino decisions about locations, methods and conservation tradeoffs
• Post-w88 casino treatment decisions, such as seeding methods and species mixtures
• Weed w88 casino, such as locations, timing and methods
• Grazing guidelines for post-w88 casino grazing and targeted grazing to reduce fuels
• Landscape prioritization, which uses geospatial analyses and mapping

“We receive questions or stated needs from our region's land managers/practitioners, then we develop products or activities that synthesize the science to answer the questions and meet the needs,” said MontBlanc, who has been with the w88 casino Exchange since it began in 2010 in the Department of Natural Resources & Environmental Science. “These products and activities are often developed or led by research and management teams, then we advertise through our newsletter and partner agency channels to distribute the information and/or bring everyone together.”

The project is governed by a 12-person steering committee and a 10-person advisory committee made up of researchers and managers from various agencies and institutions across the five states that make up the Great Basin: w88 casino, Utah, Idaho, Oregon and California.

“The committees come together regularly to discuss w88 casino needs and plan activities to meet those needs,” MontBlanc said.“We then reach out to subject experts, sometimes within but more often outside our committee groups, to lead those activities.So far, all of our activities have been open to the public, but our primary audience is land managers/practitioners and researchers.”

The Great Basin w88 casino Science Exchange is one of 15 regional w88 casino science exchanges sponsored by the national Joint w88 casino Science Program.

“This project aims to fill any communication gaps between scientists and managers, so that we all know what works, what doesn't, and what we still need to know about managing fires in the Great Basin,” Elizabeth Leger, professor of biology and lead project manager for the Great Basin w88 casino Science Exchange, said. “We have been doing this for 10 years and are going strong”
