Current Research

My current research focuses on providing the National Forest System with the science foundation for a National Reforestation Strategy, understanding  the long-term processes of tree root system architecture in response to nursery practices and on-going mechanical stresses, evaluating biochar to improve nursery efficiencies, and describing long-term effects on carbon and nitrogen pools under different land management and silviculture scenarios.

I am also Director the Western Center for Native Plant Conservation and Restoration Science, a collaboration of scientists in the Pacific Northwest, Pacific Southwest, and Rocky Mountain Research Stations working in these fields.

Research Interests

My research interests include all aspects of propagating and outplanting native plants. From the nursery perspective, my research includes nursery production systems, specifically propagation, plant-disease interactions, plant nutrition, and water management. From the outplanting perspective, my research includes assisted migration as a management adaptation to climate change, functional restoration of plant communities, and long-term development of tree root systems.

Past Research

My research has improved the process of native plant propagation. Native plant species are produced with my protocols and my protocol format is routinely followed in the literature and the Native Plant Propagation Protocol Database. My seminal work on quantifying errant discharge of water and nutrients using novel techniques I developed led to science-based options to apply water and fertilizer more efficiently and sustainably. Basic research on nursery root diseases and the subsequent best management plans that my teams developed significantly reduced incidence of this serious pathogen. We found that the fungus Fusarium commune, rather than Fusarium oxysporum, is the more virulent pathogen, supplanting existing concepts about this nursery disease. Our development of a rapid molecular assay to discern this disease has markedly changed the paradigm of future research endeavors concerning this nursery pathogen, and has potential to revolutionize disease assessment in nurseries by providing real-time information. My teams have developed and advocated methods to avoid or mitigate pitfalls of confounding factors in nursery research and in deploying stocktype trials. I synthesized and delivered my research, along with that of peer scientists, and subsequently provided nursery managers and field restorationists holistic tools; some tools have been translated into Spanish, Dari, Creole, French, and Arabic. To improve communication within the native plant propagation profession, my Internet-based propagation protocol database, and the 3150 native plant propagation protocols in it, was accessed 12,675 times during 2019. I led efforts to bridge the gap between native plant propagation and native plant deployment by initiating a new journal that is innovative because it publishes refereed research and general technical articles to encourage “cross pollination” among researchers and field professionals. Recent work showing on-going changes to coarse root system architecture challenges existing tree-stability paradigms and provides new conceptual models. I co-led the WO-requested effort to synthesize the science underpinning contemporary approaches to forest restoration, including native plant deployment, and argue for approaching forest restoration (and other ecosystems as well), from a functional standpoint. Team work with assisted migration challenges existing paradigms about appropriate plant material transfer guidelines, lays the groundwork for future research in assisted migration, and in concert with functional restoration, is contributing significantly to, and expanding the debate about, restoration practices in response to changes in climate.

Why This Research is Important

In the US, more than 1400 native plant nurseries, operated by federal, tribal, state, private, and not-for-profit entitiies, annually produce more than a billion seedlings for reforestation and restoration. Ensuring seedlings are produced efficiently and with high quality reduces costs and improves seedling performance (survival and growth) after outplanting. The end result is that restoration work to maintain ecosystem function is done in the most efficient and economic ways possible. In addition, my research with assisted migration and functional restoration will help ensure that appropriate plant materials, in terms of adaptation, are applied to the landscape.

    Looking up at western larches changing color.
    Concern about changing climate is focusing attention on how silvicultural treatments can be used to regenerate or restore forested landscapes. In this study we leveraged a 30-year-old forest management-driven experiment to explore the recovery of woody species composition, regeneration of the charismatic forest tree species western larch, and vegetation and soil carbon and nitrogen pools. 
     Northeastern California Plateaus Bioregion Science Synthesis Document Cover
    The new publication, Northeastern California plateaus bioregion science synthesis (Gen. Tech. Rep. RMRS-GTR-409), has a northeastern California focus on sagebrush rangeland, dry pine forestland, juniper forests, habitat and wildlife, society, and response to disturbances, particularly those related to climate.
    A researcher crouches next to an excavated root system on a dirt slope.
    An increase in the frequency and intensity of storms is one aspect of changes to the global climate. Strong winds can uproot trees, generating adverse environmental and economic outcomes. Our research is revealing how trees produce and distribute new roots to remain stable and upright, including how individual roots react to mechanical forces by allocating biomass in specific patterns.
    Milkweed plants are an important host species for both monarch larvae and adult butterflies.
    Iconic monarch butterflies are disappearing from the landscape. They require milkweed plants to complete their life cycle. Milkweed seeds are often produced for restoration in nurseries in special beds. Our work shows that once these beds have served their purpose, milkweed taproots can be harvested, stored, and used for restoration, thus increasing the benefit of these beds.

    The number of global initiatives for forest restoration, and the scope of these initiatives, continues to increase. An important tool for meeting objectives of these global initiatives is reforestation, achieved by natural processes or by tree planting. Worldwide, organizations are challenged to most efficiently and effectively direct resources to the most critical reforestation needs. Currently in the United States, the reforestation efforts of the USDA Forest Service, are challenged by changes in policy, funding, climate change, and mega-fires, to name a few, and identifying strategies for timely successful reforestation at scale is needed.

    Restoration and reforestation using nursery-produced seedlings can be an effective means of increasing successful establishment and rapid growth following outplanting. This, in turn, can accelerate the recovery trajectory of these ecosystems. However, in many ecosystems of the world, seasonal changes as well as changing climate can create dry conditions that are not favorable to seedling establishment.

    Focusing on wildflowers (forbs) during restoration work in the western sagebrush ecosystem can benefit sage-grouse, pollinators, and the iconic Monarch butterfly. Can a more holistic approach be taken to maximize the effectivness of wildlife conservation? Outplanting forb seedlings in high-density islands may be a way to accelerate the pace of restoration, reduce the amount of seeds required, and provide critical linkage among remaining high-quality sagebrush habitat.
    RNGR specialists provide necessary on-site support to nursery managers to improve production of native plants for reforestation and restoration.
    The Reforestation, Nurseries, and Genetic Resources (RNGR) Team, established through a Forest Service memorandum of understanding, is tasked with transferring information on native plants, including their collection, propagation, and deployment. One issue the team addresses is ensuring that nursery managers, reforestation and restoration specialists, and others in related fields receive timely information.

    The estimated billion acres globally of degraded forests presents a formidable challenge to scientists, managers, and policymakers. To provide managers with an understanding of the many factors to be considered in planning and undertaking forest restoration, Forest Service scientists synthesized information on contemporary approaches to forest restoration, resulting in two publications and an expert workshop.

    The Forest Service’s Reforestation, Nurseries, and Genetic Resources Team provides an important forum for Native American tribes to network regarding native plant production and restoration. Team leaders have worked with nearly 80 tribes and one-on-one with more than 500 tribal members across the United States and Canada, teaching them how best to propagate culturally significant plants for their own uses.

    Researchers compiled a literary database about native plant transfer guidelines, climate change, and assisted migration. This database can help inform scientists, land managers, and university students about climate change and assisted migration through presentations and publications that cover the historical, biological, social, legal, and ethical aspects of assisted migration.

    The Lassen and Modoc National Forests intend to update their Forest Plans, guided by the 2012 Planning Rule. This requires public and tribal input throughout the process and embraces the fact that ecological, social, and economic objectives are interrelated. Because ecological, social, and economic conditions have changed since the original forest plans were written and new science is available, preparing a science synthesis, guided by input from the public, tribes, and forest staffs, is the first step in a multi-step process that eventually leads to revised forest plans.
    Successful ecosystem restoration often relies on outplanting seedlings grown in nurseries. These seedlings must be of high quality; a healthy, vigorous root system is essential. This project examines how root modification achieved in nurseries affects long-term root architecture and current fine-root growth of ponderosa pine.
    The goal of this partnership between RMRS and the Curlew National Grassland is to restore pollinator habitats and understand the best strategies to support forest botanists. Through a series of projects, partners will look into the needs and pitfalls of creating a seed menu tool. Specifically, the project will analyze the effectiveness of strategically planted forbs, or "islands", in restoring pollinator communities.
    Because milkweed plants (Asclepias spp.) readily reproduce from their roots, scientists examined how roots could be harvested in fall, stored during winter, and then outplanted in spring. Scientists found that roots can be successfully stored during winter. This provides land managers with another tool for increasing monarch butterfly habitat.  
    Rocky Mountain Research Station scientists and their partners are evaluating biochar as a seed coating and as an amendment to nursery substrates to improve germination and growth of native plants. The goal is to reduce costs associated with restoring ecosystems.
