Climate change and fire in the Southwest
Date: Wednesday, August 26, 2015 1pm MDT (12pm AZ)
Presenter: Larissa Yocom, Northern Arizona University
Global climate change will lead to shifts in climate patterns and fire regimes in the Southwest over coming decades. The intent of this webinar is to summarize the current state of scientific knowledge about climate change predictions in the Southwest as well as the pathways by which fire might be affected. While the paper is focused on the Southwest, in particular Arizona and New Mexico, some of the material cited covers a broader area.
This webinar is based off the SWFSC working paper of the same name. You can download it here.
Connecting resilience science with decision-making: Guidelines for the effective development and application of scientific information – July 8, 2015
This webinar describes the results of a study that sought to identify barriers and opportunities to the use of scientific information about resilience for decision-making and on-the-ground management. Data for this study was collected from interviews that were conducted with scientists, managers, and other stakeholders following “Fostering resilience in Southwestern ecosystems: A problem solving workshop”, which was held in Tucson, Arizona, in February 2014. Results are organized according to four major themes: application of scientific information, development of scientific information, communication of scientific information, and scientific information needs. Recommendations for effectively connecting resilience science with decision-making are also provided. Click here to view a recording of this webinar!

Effects of climate variability and accelerated thinning on watershed-scale runoff in Southwestern ponderosa pine forests – April 15, 2015
The recent mortality of up to 20% of forests and woodlands in the southwestern United States, along with declining stream flows and projected future water shortages, heightens the need to understand how management practices can enhance forest resilience and functioning under unprecedented scales of drought and wildfire. To address this challenge, a combination of mechanical thinning and fire treatments are planned for 238,000 hectares (588,000 acres) of ponderosa pine (Pinus ponderosa) forests across central Arizona, USA. Mechanical thinning can increase runoff at fine scales, as well as reduce fire risk and tree water stress during drought, but the effects of this practice have not been studied at scales commensurate with recent forest disturbances or under a highly variable climate. Modifying a historical runoff model, we constructed scenarios to estimate increases in runoff from thinning ponderosa pine at the landscape and watershed scales based on driving variables: pace, extent and intensity of forest treatments and variability in winter precipitation. We found that runoff on thinned forests was about 20% greater than unthinned forests, regardless of whether treatments occurred in a drought or pluvial period. The magnitude of this increase is similar to observed declines in snowpack for the region, suggesting that accelerated thinning may lessen runoff losses due to warming effects. Gains in runoff were temporary (six years after treatment) and modest when compared to mean annual runoff from the study watersheds (0-3%). Nonetheless gains observed during drought periods could play a role in augmenting river flows on a seasonal basis, improving conditions for water-dependent natural resources, as well as benefit water supplies for downstream communities. Results of this study and others suggest that accelerated forest thinning at large scales could improve the water balance and resilience of forests and sustain the ecosystem services they provide.

Increased wildfire has been observed with the displacement of native cottonwood-willow (Salix and Populus spp.) gallery forests by invasive, non-native tamarisk (Tamarix spp.) in desert riparian zones of North America. Greater post-fire recovery of Tamarix relative to native species suggests a Tamarix fire trajectory where repeated fire excludes native riparian species. This work synthesizes several experiments and addresses 2 questions: 1) Is there a positive feedback between Tamarix and fire intensity that excludes native vegetation? 2) Can the Tamarix fire trajectory be altered to allow the coexistence of natives?

Fire and climate history of the western San Juan Mountains, Colorado: Integration of tree-ring and alluvial-sediment methods –February 2015
This webinar presents research on the historical fire regimes of the western San Juan Mountains in southwestern Colorado, where the landscape provided a unique opportunity to sample tree-ring and alluvial-sediment records in the same study sites. Knowledge of historical fire regimes (frequency, size, severity) can help support management plans to reduce forest densities and increase resiliency of forest stands to current and future climate changes. We collected tree-ring data from three watersheds and evaluated the influence of aspect and fire barriers on fire frequency and severity, as well as, the influence of regional climate on historical fire events. Sediment-based reconstructions from the valley bottoms illustrated several peaks in fire activity over the past ~2,500 years, representing an increased proportion of high-severity fire during certain climatic periods. We associated these peaks in fire activity with severe drought episodes, which were often preceded by two – three decades of wet conditions. In summary, our study shows that future drought and warming temperatures have the potential to increase the frequency and severity of fires, given the abundant fuel loads in pine-dominated forest types in this landscape.

In partnership with the Northern Rockies Fire Science Network, Sean will present the results from a JSFP-funded study that highlights the ability of wildfire to act as a fuel treatment. This study evaluated whether or not wildfires limited the occurrence, size, and severity of subsequent wildfires in four large wilderness complexes in Idaho, Montana, and New Mexico. Our focus on protected areas was intended to minimize anthropogenic factors that may affect fire behavior and effects (e.g., roads and fuel treatments). Results suggest that 1) wildfires reduce the probability that subsequent fires will ignite and spread, 2) wildfires reduce the size of subsequent fires by acting as fuel breaks, and 3) the severity of subsequent fires is significantly lower in areas that have recently burned compared to areas that have not. The strength and longevity of the moderating effect vary by study area, suggesting that ecosystem-level processes controlling fire regime characteristics and regrowth of vegetation are responsible for these differences.

Fire cuts across administrative boundaries and our restoration work needs to as well. Whether it is multijurisdictional planning or multiagency prescribed burning, working across boundaries presents a unique set of challenges. In this webinar, Eytan Krasilovksy will discuss multijurisdictional NEPA planning in the Rio Trampas watershed and this year’s multiagency controlled burn near Black Lake, New Mexico. We encourage participants to bring their own examples and share their lessons learned during the discussion period. Click here to watch webinar recording!

Fire suppression has been the dominant fire management strategy in the West over the last century. However, managers in the Gila National Forest and Saguaro National Park have allowed fire to play a more natural role for decades. In a newly published report, we summarize the effects of these fire management practices on key resources, document common challenges in implementing these practices, and provide lessons for how to address those challenges.

A panel perspective on regeneration in Southwest pine forests after high severity wildfire –August 2014
The Southwest Fire Science Consortium is hosting a panel discussion on regeneration of pine forests after high severity wildfires. Recent fires such as the 2011 Las Conchas Fire have created large (> 10,000 acres) patches where high severity fire killed all trees and limited the seed source for returning pine trees to the area. These large patches have raised the fear that uncharacteristic fires may convert large areas of pine forest to other vegetation such as oak brush. The goal of the webinar is to foster discussion about post-fire regeneration and help identify what the existing research indicates, what projects currently underway will contribute, and what research questions need to be addressed. The webinar will start with brief presentations by a range of researchers and experts on the topic. To watch a recording of this webinar, click here!
People, fire, and insects: Three centuries of disturbance interactions along an ecological gradient of the Pinaleño Mountains, Arizona –June 2014
In the Pinaleño Mountains of Southeast Arizona, a series of high-severity insect outbreaks and fires in recent decades appear to be unprecedented in the historical record. These disturbances raise concerns about forest resilience and long-term sustainability of one of the most ecologically diverse landscapes in the southwest. We used detailed reconstructions of forest successional dynamics, disturbance processes, and climate variability over more than 350 years to provide context for recent disturbances, to identify specific conditions of concern, and to provide some recommendations on future management actions. Please join us for this unique in-depth study of the biogeography of an Arizona Sky Island that has been altered by more than a century of fire exclusion and a series of complex interactions among natural and anthropogenic ecosystem processes.

To address concerns regarding how to prioritize treatments across the forests, the Ecological Restoration Institute received funding from the USDA Forest Service to identify priority treatment areas across the Apache-Sitgreaves National Forests. In addition, Forest Service personnel stated a need to identify areas within the Wallow Fire perimeter that remain vulnerable to uncharacteristic wildfire. Existing Forest Service spatial data layers (Mid-scale vegetation diameter class, species and canopy cover) were used to identify restoration opportunity areas. Additional data layers (topography, land management designation, Wildland Urban Interface) were added to the analysis to identify priority restoration areas on the landscape. There are more than 133,000 acres within the Wallow fire perimeter that consist of priority restoration vegetation which experienced ≤50% basal area mortality and were thus deemed as continuing to be vulnerable to uncharacteristic wildfire. Less than half of this falls within the WUI boundary. To watch the recording, click here!
What is Climate Change? How will our changing climate impact seasonal weather conditions across the Southwest? – February 2014 (as pre-work for resiliency workshop)
Restoring Composition and Structure in Southwestern Frequent-Fire Forests: A science-based framework for improving ecosystem resiliency – February 2014 (as pre-work for resiliency workshop)
Eytan Krasilovsky will share challenges and lessons learned surrounding the Forest Guild’s recent Black Lake Training Exchange. Forest Guild and the New Mexico State Land Office, with support from the Nature Conservancy’s Fire Learning Network, convened a grant funded training exchange to burn 900 acres of state trust lands in a wildland-urban interface in northern New Mexico. Funded by the USDA Forest Service’s Collaborative Forest Restoration Program, a diverse cadre of local and national firefighters was convened for 5 days and was comprised of both experienced and first-time firefighters. The after-action reviews contributed to meaningful lessons learned for the parties involved but also for those interested in implementing collaborative burning efforts elsewhere.

Jeremy Bailey, a career firefighter and prescribed fire burn boss, will discuss the Fire Learning Network’s Training Exchange program and how it is being used to train numerous local workforces to advance burning across all lands. In the past seven years, these training exchanges have been deployed on federal, state and private lands, bringing together federal, state and private firefighters of all skill levels. They also integrate scientists, researchers, local land managers and cultural aspects of fire to bring more “good fire” to the landscape. Due to technical difficulties, a recording of this webinar is unavailable. Jeremy’s powerpoint presentation can be downloaded here.
In this webinar, we will discuss research on the role and use of prescribed fire in the western Great Plains, focusing on studies conducted in the shortgrass steppe of Colorado over the past decade. We will discuss the fuel loads and weather conditions under which prescribed burning has been possible (including considerations of drought versus wet years), and associated fire temperatures. We will then examine the ecological role of prescribed burning in terms of effects on cattle grazing distribution and production, differential effects on herbaceous plants versus cactus and dwarf shrub species, and consequences for grassland bird habitat. We will also discuss differences in the effects of burns conducted in spring versus fall and at varying frequencies. Prescribed burn planning in shortgrass steppe is complex because achieving specific goals while mitigating potential negative effects requires consideration of many variables.

The southwestern United States encompasses many ecosystems with intimate and inseparable relationships with fire. It is well accepted that fire plays an integral role in the ecology and maintenance of many forest and grassland types in the southwest. Fire on these landscapes not only shapes how those systems function but long-term fire effects provide for current and future interactions with fire. Focusing specifically on past fire occurrences and how current fires interact with these areas, I provide an overview of management opportunities, fire severity and overall interactions. Burn severities within vegetation types are compared for areas that have experienced documented recent fires versus those area that have not. Fire effects from past fires that are evident in current live and dead fuels conditions increase the decision space for suppression and management strategies and tactics. Results illustrate the importance of fire on these ecosystems not only from an ecological perspective but in the form of opportunities and choices for future fire management. Watch recording here!
How will climate change and treatments affect future forests? Testing alternatives with the Climate-FVS model – September 2013
Under current conditions, large, severe wildfires are a fact of life in southwestern ponderosa pine forests. What will burned systems look like over the coming decades under warming climate? Do management treatments make a lasting difference or will climate override their effects? We applied the relatively new feature of the Forest Vegetation Simulator (FVS) called Climate-FVS, which modifies the widely used FVS model to make it simulate effects of climate change. The short answer: climate change has major effects on our test site, the Rodeo-Chediski fire on Arizona’s Mogollon Rim. At the severe end of the climate scale, forests are nearly eliminated. But under more moderate climate change scenarios, management intervention makes a big difference. The strengths and weaknesses of building climate change into forest modeling are important to understand for making informed decisions. Watch recording here!

Charlotte and Helen teamed up to present this webinar that connected science and management of fire in the Davis Mountains of west Texas. Three wildfires burned through the pinyon-juniper-oak forests of the Davis Mountains in 2011 and 2012. Fuel treatments (prescribed fire, thinning, and thinning+prescribed fire) applied before the wildfires reduced fire severity and subsequent tree mortality relative to areas that experienced wildfire alone. Overall tree mortality was still high, due partly to drought conditions at the time of the fires. Watch recording here!
Effects of Wildland Fire on Lowland Leopard Frogs and their Habitat at Saguaro National Parks – June 2013
Don Swann is a biologist at Saguaro National Park, Tucson, Arizona, where he has worked for more than 20 years. He has an MS in Wildlife and Fisheries from University of Arizona. Don’s projects include collaborative research and long-term monitoring of saguaros, desert tortoises, mammals using wildlife cameras, and inventories of reptiles and amphibians. He has been the lead on monitoring and management of lowland leopard frogs at the park since 1996.
Large wildfires can have dramatic watershed effects, including sedimentation of aquatic habitat that have the potential to impact stream species such as fish and frogs. In arid systems it may take years, even decades, for sediments to wash out from downstream areas. This talk will present an overview of the long-term interaction between wildfires and aquatic species in Arizona, with a particular focus on the lowland leopard frog in Saguaro National Park’s Rincon Mountain District. We have been monitoring leopard frog populations, sediment, and water availability since 1996, including in streams where a high percentage of the watershed burned in 1999 and 2003 as well as streams where no fires occurred. The talk will also discuss pre- and post-fire management options for fire and aquatic frogs and other species. Watch recording here!
The structure of fire size distributions: a broad view of interacting gradients in wilderness management, spatial climate, and topography in three western regions – May 2013
Determining the effects of land management on fire regime characteristics is complicated by the interaction of several factors that vary in space and time. First, fire size and frequency are linked to climate conditions, including drought, as well as wind and temperature that define weather conditions during burning. Second, topography and fuels influence ignition locations, fire spread, and behavior which play a role in determining fire frequency and size of individual fire events. Last, and importantly, comprehensive records that quantify where and when various management practices including fire suppression and other strategies occurred are not available at regional scales. Given these challenges, we designed our study to examine the scaling of fire size distributions from 1984-2007 along a “wilderness gradient” in three regions: the Southwest, Northern Rockies, and Sierra Nevada. We constructed the gradient to reflect our expectation that fire size distributions in wilderness interiors, or core areas, had the greatest likelihood of being influenced by natural burning practices. Our expectation was met in one region, but not in the other two. The importance of large fires in structuring fire size distributions decreased in wilderness interiors of the Southwest, but the opposite trend was observed in the other two regions. In both the Sierra Nevada and the Southwest, several variables limited the role of large fires across the wilderness gradient. In contrast, topographic and climate/fuel variables worked in concert to increase the importance of large fires in the Northern Rockies. The unique climatic, topographic, and ecosystem characteristics of each region provided a useful context for understanding the dynamics of fire size distributions and important differences among geographic regions. In this webinar, I present our findings with the goal of painting a picture of the multiple, interacting influences which shape fire size distributions within and around western wilderness.

Impacts of fire hazard assessment and fuel reduction priorities on mega-fire outcomes: A hypothetical test using the Wallow Fire in Arizona– April 2013
Uncharacteristically large and severe wildfires, or mega-fires, are occurring with increasing frequency over the last decades in the western United States. The 2011 Wallow Fire, a 538,049-acre (217,740-hectare) fire in the conifer forests of eastern Arizona, provided the opportunity to compare the effectiveness of different hypothetical treatment scenarios at reducing fire effects. To evaluate how treatment scenarios based on different values at risk influence landscape-level fire effects, we used FlamMap to model fire behavior under the following priority scenarios: 1) 2010 pre-fire conditions; 2) a Wildland-Urban Interface (WUI) priority (based on national priorities) where stands with high fire risk (Fire Program Analysis data) within WUI boundaries were “treated” to produce lower canopy cover and crown bulk density and fire models more indicative of open-canopied conifer forests; 3) a “Restoration Opportunity” priority, where forests stands in frequent-fire systems that exhibited closed canopy and high tree densities occurring across the landscape were treated as above; and 4) a scenario that represented a blend of 2 and 3. Key findings included: 1) Fuel reduction treatments were effective at reducing fire behavior and reducing risk to prioritized values like communities. 2) WUI-only treatments resulted in large, contiguous areas with unchanged crowning potential across the pre-treatment landscape. Continuous fuels in uncharacteristically high loadings continued to support active and passive crowning in 20,000 – 40,000-acre (~8,000 – ~16,000 hectare) blocks with potential losses to ecological integrity in forests adapted to more frequent fire conditions. 3) Fuel reduction treatments simulated at broader scales had bigger impacts on overall reduction of crown fire within the Wallow Fire perimeter. The continued investment of the majority of treatments in the WUI does provide protection for communities; however, our results suggest this strategy alone will not solve continuing ecological degradation from uncharacteristically severe fire on the greater landscape.

Implementing the Mexican spotted owl revised recovery plan: Conducting fire management in owl habitat– February 2013
The Mexican Spotted Owl Recovery Plan, First Revision, was released on December 17, 2012. The Recovery Team used the best available science to delineate actions we think are required to recover and protect the owl. This Recovery Plan presents realistic and attainable goals for recovering the owl, involving forest habitat management and vigilant monitoring. The goals are flexible in that they allow local land managers to make site-specific decisions. To accomplish the recovery of the Mexican spotted owl, the recovery strategy has five key elements designed to conserve the subspecies throughout its range: 1) protect existing populations; 2) manage for habitat into the future; 3) manage threats; 4) monitor populations and habitats; and, 5) build partnerships to facilitate recovery. The webinar presentation will briefly summarize all of the components of the plan, but focus on recovery recommendations dealing with fire and fire management.

Dr. Williams will discuss his recent work to derive a forest drought-stress index (FDSI) for the southwestern United States using a comprehensive tree-ring data set representing AD 1000–2007. This FDSI is linked to measures of forest productivity, mortality, bark-beetle outbreak and wildfire. If climate models are accurate, the mean forest drought-stress by the 2050s will exceed that of the most severe droughts in the past 1,000 years. Collectively, the results foreshadow twenty-first-century changes in forest structures and compositions, with transition of forests in the southwestern United States, and perhaps water-limited forests globally, towards distributions unfamiliar to modern civilization. See related publication here. Listen to a recording of this webinar here!
Extreme fire behavior indicates a level of fire behavior characteristics that ordinarily precludes methods of direct control action. One or more of the following is usually involved: high rate of spread, prolific crowning/spotting, presence of fire whirls, and strong convection column. This webinar will summarize the recent JFSP publication that connects the weather, fuel, and topographic factors that contribute to development of extreme fire behavior. See related publication here.

Recent science communication studies of the federal fire management community suggest managers access research via informal information networks, and that these networks vary by both agency and position. We used a phone survey to understand the informal science communication networks of fire professionals in two of the Joint Fire Science Program’s regional knowledge exchange consortia: the Northern Rockies Fire Science Network and the Southwest Fire Science Consortium. In these two regions, we sampled federal and tribal decision makers, fire management officers, fire ecologists, and fuels specialists to determine: 1) who they go to for scientific information about fuels or fire effects science, 2) why they go to these individuals, and 3) how they communicate with these individuals. Informal science communication networks varied by both professional position and information type (fuels vs. fire effects), with fuels specialists being universally important informants about science. In contrast to a broadcast approach to science communication, a more strategic approach based on understanding the characteristics of fire science communication networks is expected to shorten time lags to diffusion.

Hydrologic Impacts of High Severity Wildfire: Learning from the Past & Preparing for the Future – January 2012
Fires are increasing in size, frequency, and severity. Simultaneously, development continues in the wildland-urban interface and the number of people living in or visiting forest areas is growing. Understanding the post-fire hydrologic response of watersheds as observed on the Schultz Fire of 2010, is paramount for effective risk management and mitigation of post-fire hydrologic and geomorphic hazards. Equally important is educating communities that are at high-risk for post-fire flooding and sedimentation hazards. This presentation encompasses research on hydrologic and geomorphic impacts of past fires such as the Schultz Fire, a real-time perspective on recent post-fire hazards and mitigation (including the 2010 Schultz Fire and others) and identifies some high-risk areas where opportunity exists to educate and prepare the public for post-fire hazards before the flames.
