Seth Munson, Ph.D.
Seth Munson is an ecologist with the Southwest Biological Science Center in Flagstaff, Arizona. His research focuses on plant-soil interactions in dryland ecosystems and how these interactions are affected by climate and land use changes.
Much of Dr. Munson's research aims to understand the dynamics of dryland ecosystems at long temporal and broad spatial scales, and employs a multidisciplinary approach. His work seeks to improve the management of arid and semi-arid lands, including determining effective ecological restoration strategies, and is done in close collaboration with several land management agencies.

Biotic and abiotic treatments as a bet-hedging approach to restoring plant communities and soil functions
Two related concepts in restoration ecology include the relative interchangeability of biotic and abiotic restoration treatments for initiating recovery and bet hedging using multiple restoration approaches to increase the likelihood of favorable restoration outcomes. We used these concepts as a framework to implement a factorial experiment including biotic (outplanting greenhouse-grown individualAuthorsAudrey J Rader, Lindsay P. Chiquoine, James F. Weigand, Judy L Perkins, Seth M. Munson, Scott R AbellaOntogenetic trait shifts: Seedlings display high trait variability during early stages of development
Characterizing variation in plant functional traits is often key to understanding community-level processes and predicting ecosystem responses to environmental change. Trait-based ecology has focused on interspecific trait variation, but sources and consequences of within-species ontogenetic trait variation, particularly during early stages of development, remain understudied.Using a manipulativeAuthorsCaroline Ann Havrilla, Seth M. Munson, Charles Yackulic, Bradley J. ButterfieldDrivers of seedling establishment success in dryland restoration efforts
Restoration of degraded drylands is urgently needed to mitigate climate change, reverse desertification and secure livelihoods for the two billion people who live in these areas. Bold global targets have been set for dryland restoration to restore millions of hectares of degraded land. These targets have been questioned as overly ambitious, but without a global evaluation of successes and failuresAuthorsNancy Shackelford, Gustavo B. Paterno, Daniel E. Winkler, Todd E.

Extreme drought can strongly impact belowground communities and biogeochemical processes, including soil microbial community composition and extracellular enzyme activities (EEAs), which are considered key agents in ecosystem carbon (C) and nutrient cycling. However, our understanding of how seasonal timing of drought during the growing season affects soil microbial communities and their activityAuthorsWenlan Gao, Sasha C. Reed, Seth M.

Dryland (arid and semi-arid) ecosystems globally provide more than half of livestock production and store roughly one-third of soil organic carbon (SOC). Biogeochemical pools are changing due to shrub encroachment, livestock grazing, and climate change. We assessed how vegetation microsite, grazing, and precipitation interacted to affect SOC and total nitrogen (TN) at a site with long-term grazingAuthorsHeather L. Throop, Seth M. Munson, Nicole Hornslein, Mitchel P McClaranSupporting the development and use of native plant materials for restoration on the Colorado Plateau (Fiscal Year 2020 Report)
A primary focus of the Colorado Plateau Native Plant Program (CPNPP) is to identify and develop appropriate native plant materials (NPMs) for current and future restoration projects. Multiple efforts have characterized the myriad challenges inherent in providing appropriate seed resources to enable effective, widespread restoration and have identified a broad suite of research activities to providAuthorsRobert Massatti, Daniel E.

The southwestern U.S. is a global hotspot of climate change. Models project that temperatures will continue to rise through the end of the 21st century, accompanied by significant changes to the hydrological cycle. Within the Sonoran Desert, a limited number of studies have documented climate change impacts on the phenology of native plant species. Much of this phenological work to understand climAuthorsLuke J Zachmann, John F. Wiens, Kim Franklin, Shelley D. Crausbay, Vincent A. Landau, Seth M.

Managing climate impacts to natural resources in protected areas can be hampered by lack of monitoring data, poor understanding of natural resource responses to climate, or lack of timely condition assessments that can inform management actions. Here we demonstrate the utility of water balance as a tool for understanding natural resource responses to climate by developing case studies focused on sAuthorsDavid P. Thoma, Michael T. Tercek, E.

Restoration and rehabilitation are globally implemented to improve ecosystem condition but often without tracking treatment expenditures relative to ecological outcomes. We evaluated the cost‐effectiveness of widely conducted woody plant and herbaceous invasive plant removals and seeding treatments in drylands of the western United States from 2004 to 2018 to determine how land managers can optimiAuthorsSeth M.

Droughts have increased globally in the twenty-first century and are expected to become more extreme and widespread in the future. Assessments of how drought affects plants and ecosystems lack consistency in scope and methodology, confounding efforts to mechanistically interpret structural and functional impacts and predict future transformations under climate change. To promote integration amongAuthorsSeth M. Munson, John B. Bradford, Kevin R.

The ecosystems along the border between the United States and Mexico are at increasing risk to wildfire due to interactions among climate, land-use, and fuel loads. A wide range of fuel treatments have been implemented to mitigate wildfire and its threats to valued resources, yet we have little information about treatment effectiveness. To fill critical knowledge gaps, we reviewed wildfire risk anAuthorsKatherine M. Laushman, Seth M. Munson, Timothy N. TitusNon-USGS Publications**
