Current Research

Much of my current research focuses on (1) developing an understanding of the factors that determine ecological resistance to invasive species and that affect ecological resilience to disturbances like wildfire, and (2) using that information to develop effective management and restoration approaches. Study systems include arid and semi-arid shrublands, woodlands, riparian ecosystems and alpine ecosystems.

Research Interests

My research interests include: 1) disturbance/restoration ecology, 2) global change processes, 3) invasive species, especially annual grasses, and 4) arid and semi-arid shrublands, woodlands, riparian ecosystems and alpine ecosystems.

Past Research

My research has focused on the ecology, restoration, and management of ecosystems in the western US.

  • My early research focused on restoration of severely disturbed ecosystems with an emphasis on alpine areas. This work increased understanding of seed dispersal and seedling establishment processes in these ecosystems and was published in various journals including Ecology.
  • A major effort in which I am still involved focuses on restoring and maintaining riparian and meadow ecosystems with an emphasis on the Great Basin. This interdisciplinary work involves geomorphologists, hydrologists and plant ecologists, and resulted in numerous synthetic publications including a book and GTR on the factors affecting stream, riparian ecosystem, and meadow dynamics.
  • A long-term focus of my research has been on understanding effects of global change processes and management actions in Cold Desert shrublands and woodlands. This work has emphasized understanding the importance of environmental and productivity gradients on ecosystem response to (1) annual grass invasion, (2) woodland expansion, and (3) wildfire and management actions such as prescribed fire and tree cutting.
  • Consistent elements of my research include increasing understanding of relationships among environmental factors (precipitation, temperature), ecosytem attributes (soil water and nutrient availability) and biotic processes (plant establishment and community productivity).

Why This Research is Important

Developing an understanding of ecosystem resistance to invasive species and resilience to disturbance is essential for prioritizing management activities across the landscape and developing the most effective actions. This requires knowledge of the environmental factors and abiotic and biotic attributes and processes that determine ecosystem responses to global change and management actions. My colleagues and I have developed this information for key ecosystems in the Cold Deserts Ecoregion.

  • Riparian and meadow ecosystems - A process based approach has been developed for maintaining and restoring these ecosystems that is based on knowledge of their geomorphology, hydrology and vegetation communities. This work has been synthesized in a 2004 Island Press book and a 2011 RMRS GTR-258, both edited by Chambers and Miller (see above).
  • Cold Desert shrublands - The conceptual basis for evaluating Cold Desert shrublands based on resistance to invasion and resilience to disturbance has been developed, and an integrated, strategic approach for categorizing these shrublands based on their relative resilience and resistance has been devised. This work has been used to link ecosystem resilience and resistance with species conservation requirements, specifically Greater Sage-Grouse, and is being used to prioritize land management actions to decrease the threats of invasive annual grasses and wildfire by both BLM and FS in sagebrush ecosystems.

Sagebrush steppe and pinyon-juniper ecosystems: effects of changing fire regimes, increased fuel loads, and invasive species
    Prescribed fire operations in Underdown Canyon Demonstration Project.
    The use of prescribed fire to reduce expansion of pinyon and juniper to sagebrush ecosystems is a commonly used by managers but can have unwanted consequences. In this Joint Fire Sciences Program Demonstration Project, we show how seeding native species after prescribed fire can decrease invasion of nonnative annual grasses in sites with low resistance.
    Big sage mountain brush
    An unprecedented conservation effort is underway across 11 Western states to address threats to sagebrush ecosystems and the many species that depend on them. Today, the Department of Agriculture and the Department of Interior released the Science Framework for Conservation and Restoration of the Sagebrush Biome (Part 2). The Science Framework provides a transparent, ecologically responsible approach for making policy and management decisions for sagebrush landscapes.

    Changes in fire patterns for piñon and juniper vegetation in the western United States were analyzed over a 30-year period. This is the first evaluation of its type.

    The Science Framework for Conservation and Restoration of the Sagebrush Biome (Science Framework) provides a strategic, multiscale approach for prioritizing areas for management and determining effective management strategies across the sagebrush biome.

    The Rocky Mountain Research Station holds a long legacy in sagebrush and rangeland research dating back to the 1930s. With over 70 years of research on sagebrush ecosystem dynamics as well as mechanisms to manage for resilient and resistant sagebrush ecosystems, Forest Service scientists continue as a leading resource for providing sound science to the management of these landscapes.
    Cover of Exotic Brome-Grasses in Arid and Semiarid Ecosystems of the Western US – Causes, Consequences, and Management Implications
    Invasive annual brome grasses are resulting in altered fire regimes and conversion of native arid and semi-arid ecosystems in the western United States to annual grass dominance. The problem is particularly acute in sagebrush shrublands where cheatgrass (Bromus tectorum) has resulted in annual grass fire cycles that are placing numerous native species such as greater sage-grouse at risk and threating ecosystem services such as livestock forage, hunting and recreation, and even clean air and water. This 15-chapter book examines the environmental impacts, invasiveness, environmental controls, and management alternatives for invasive annual brome-grasses.

    Sagebrush ecosystems and the more than 350 species that rely on them are highly imperiled due to persistent threats such as invasive annual grasses, pinyon and juniper expansion, and altered fire regimes. Understanding their relative resilience or recovery potential following wildfire or management treatments provides the basis for more effective selection of treatment areas and restoration strategies.
    New research from the Rocky Mountain Research Station on sagebrush ecosystems is being put to use to benefit Greater Sage-Grouse habitat on federal lands across the intermountain west.  An interagency effort initiated by the Western Association of Wildlife agencies and led by Grasslands, Shrublands, and Deserts Program Scientist, Jeanne Chambers, was used to develop a strategy for decreasing the impacts of invasive grasses and wildland fire on sage-grouse habitat. 
    There is widespread interest in understanding the effectiveness of fuel treatments in mitigating the trajectory of wildfire suppression costs and how their effectiveness and longevity can be extended over large areas and landscapes. To date, there have been several studies that used a modeling approach to evaluate fuel treatment effectiveness at the landscape scale. However, empirical studies at this scale are rare because landscape-scale fuel treatment strategies have not been fully implemented or wildfires have not burned through implemented landscape fuel treatments. A thorough evaluation of what is currently available in the literature and lessons learned from forest and rangeland managers has not yet been conducted.
    The concepts of ecological resilience and resistance to invasive annual grasses have been used to develop an understanding of sagebrush ecosystem response to disturbances like wildfire and management actions to reduce fuels and restore native ecosystems. A multi-scale framework that uses these concepts to prioritize areas for conservation and restoration at landscape scales and to determine effective management strategies at local scales has been developed by Chambers and her colleagues. Regional SageSTEP (Sagebrush Treatment Evaluation Project) data coupled with west-wide AIM (Assessment, Inventory and Monitoring) data provide a unique opportunity to refine the predictors of resilience and resistance and extend the existing multi-scale framework effort.
    The framework for restoring and conserving Great Basin wet meadows and riparian ecosystems builds upon long-term work by the research team on resilience of these ecosystems to stress and disturbance. Data and understanding of the resilience of watersheds, valley segments, and stream reaches for a large ecoregion (the central Great Basin) are being used to develop the Resilience-based Framework and to expand its applicability by assessing other common watershed types in the central and northern Great Basin.
    Over one million acres will receive treatments across the Great Basin Landscape Conservation Cooperative (GBLCC) to conserve greater sage-grouse habitat over the next decade. These treatments are intended to restore native sagebrush habitat by reducing encroachment of juniper, infestations of invasive weeds, and wildfire. This project will evaluate the effects of vegetation treatments on population connectivity, genetic diversity and gene flow of wildlife species across the full extent of the Great Basin Landscape Conservation Cooperative.
