Current Research

1. Determine ecological consequences of fire and other landscape stressors for avian communities of dry coniferous forests of the Interior West. 2. Examine breeding ecology of the black-backed, Lewis's, and white-headed woodpeckers in burned and unburned forests of the Inland Pacific Northwest. 3. Developing habitat suitability models from both field-collected and remotely-sensed data to predict bird distributions under different climate and management scenarios. 4. Developing statistically valid, standardized methods for occupancy and effectiveness monitoring of woodpeckers in relation to habitat restoration and fire management activities. 5. Determine the effect of fuels reduction treatments on habitat suitability of selected woodpeckers. 6. Provide managers with tools and results to help understand and estimate occupancy of selected woodpeckers throughout the USFS Pacific Northwest Region. 7. Develop historic and future woodpecker nesting habitats under different management & climate scenarios. 8. Identify future needs of habitat suitability for nesting woodpeckers to help guide forest restoration activities.

Research Interests

My research focuses on understanding wildlife habitat relationships to provide guidance on management activities that promote wildlife population and habitat persistence. Next steps will focus on 1) validation and refinement of habitat suitability models for woodpeckers under current conditions, 2) development of habitat suitability models for historic and future climate and land management scenarios, and 3) developing training workshops to instruct managers and biologists on creating habitat suitability maps that will be used to guide forest restoration activities (i.e. determine most appropriate locations for treatments).

Past Research

Recent efforts to mitigate severe fire effects and restore ecological function in dry coniferous forests have taken on a new urgency due to observed and anticipated effects of climate change. Currently, fuel reduction treatments are the primary focus of dry coniferous forest restoration. This will necessitate land managers to consider the implications of forest management actions on a range of resources, including wildlife. Consequently, managers need reliable information about climate-fire-vegetation interactions to effectively achieve their goals of forest restoration, while maintaining wildlife habitat and other sensitive resources. Land managers face significant challenges implementing forest restoration activities while concurrently meeting the requirements of existing laws to maintain wildlife habitat. Therefore, tools to predict potential wildlife habitat in landscapes affected by restoration activities are needed to help managers with timely decisions regarding treatment options.

Why This Research is Important

1. Co-edited a volume Fire and Avian Ecology in North America used in environmental analyses to examine effects of different fire conditions on avian species and communities. 2. Development of standardized methods for monitoring populations and habitats of cavity-nesting birds that are widely used in western forests and facilitate comparisons across studies. 3. Development of spatially explicit habitat suitability maps used for targeting management activities related to postfire salvage logging and forest restoration; areas identified as lower habitat suitability are considered for management activities, whereas those with higher suitability are identified for deferred, different, or maintenance treatments.

    Researchers studied avian relationships with wildfire to evaluate forest fire and fuels management strategies. Specifically, they document regional differences associated with historical fire regime with implications for broadly implemented strategies aimed at reducing severe wildfire risk. The results suggest that avian-fire relationships differ regionally, and therefore the best management practices for conserving or restoring avian diversity likely differ with historical fire regime.

    Increases in forest fires are expected with future changes in climate, allowing more opportunities for post-fire salvage logging. Forest managers are challenged with implementing post-fire management policies while concurrently meeting the requirements of existing laws and planning documents to maintain habitat for wildlife species associated with snags. Design criteria for post-fire salvage logging is needed to concurrently manage for economic benefits and wildlife habitat.
    Habitat suitability models provide critical information needed for forest management plans to accommodate biodiversity conservation. We are developing GIS-based application tools for forest managers that requires minimal technical expertise to create habitat maps.
    The Rocky Mountain Research Station is leading the effort to examine fire effects on populations and habitats of wildlife in dry mixed conifer forests in eight states across the western United States, including locations on National Forests, National Parks, and state and private lands. The goal of the Birds and Burns Network is to understand the ecological consequences of wildland fire, bark beetle disturbance, and forest management for wildlife in dry mixed conifer forests.
    Land managers require high-quality information on species and habitats at risk to develop effective management strategies. In the absence of information on these species and their habitats, agencies frequently err on the side of the species and make conservative, and often unnecessary, decisions relative to habitat protection. Over 20 years of research by scientists with the Rocky Mountain Research Station are helping address these information needs.
    Synergistic interactions of climate change, mountain pine beetle infestations, and wildfire are likely to catalyze landscape-scale changes in vegetation distributions, successional stage, forest structure, and wildlife habitat suitability. Our research will provide forest managers with information they need to project changes to habitat suitability for wildlife under a range of alternative climate and management scenarios.
    We are integrating multiple datasets, statistical modeling tools, and simulation approaches to quantify habitat and predict population responses by woodpecker and other wildlife species of conservation concern to natural disturbance (wildfire, bark beetle outbreaks) and forest management activities to inform adaptive management of dry conifer forests.
    Innovative quantitative approaches have been developed for evaluating wildfire and prescribed fire effects on wildlife communities in several western North American national forests.
