Current Research

In general, my research focuses on increasing our understanding of the relationships between the genetics of forest plant species and the environment. Understanding these relationships is essential to the success of a range of natural resource management activities (e.g. reforestation, gene conservation, seed transfer and invasive species management). When a plant population is not genetically adapted to cope with environmental constraints, the population's productivity or persistence may be diminished or lost. Thus, the primary motivation for my research is to provide knowledge necessary to effectively support decisions that increase or maintain ecosystem health and resilience and ecosystem services.

My present research objectives are to:

  • quantify adaptive (genetic) variation in growth and phenology; assess phenotypic selection under climate change and characterize the relationship between patterns of genetic variation and climate a) among whitebark pine populations in the interior northwestern USA and b) among and within subalpine fir populations, range wide and
  • quantify adaptive (genetic) variation in growth and phenology among and within ponderosa pine populations grown under drought stress during early seedling establishment.

    Why This Research is Important

    Genetic adaptation of forest trees is critical for maintaining ecosystem resilience, productivity and services (e.g., wildlife habitat, water quality, carbon sequestration, forest products) in the face of present and future disturbances, such as climate change, invasive species, wild fire, land-use change, etc.

    My research provides critical information to ensure that forest tree populations are adapted on the sites where they are grown, identify unique populations for conservation, identify populations at risk and predict evolutionary responses.

    Thus, this research is essential to maintain healthy forest ecosystems in the face of diverse and changing disturbance.
