Using historical datasets to test uncertainty in species distribution model projections through time.
University of Montana & University of California, Davis 2008-present
We are investigating the predictive ability of species distribution models in novel temporal and spatial domains using historical and contemporary vegetation and climate data from the mountain ranges of California, USA. We are examining how species functional traits, land-use type, and disturbance regime influences model skill and uncertainty.
The role of terrain of terrain in shaping the adaptive response of biota to climate change
University of Montana 2009- present
We are quantifying the extent to which landscape physiography influences regional climate patterns and climate displacement rates for both temperature and water balance. We are also examining historical data and paleoecological records to assess how organisms utilized terrain to mitigate against climate changes of the Quaternary.
Providing decision support for assisted migration planning to mitigate against climate change impacts
University of Montana & USFS Rocky Mountain Research Station 2010-present
We are examining current approaches for assisted migration planning with a focus on analytical methods used to quantify extinction risk and models used to identify future suitable habitat. We are developing methods that are better able to quantify uncertainty in climate change impact projections.
Past, current, and future fire regimes of the Sierra Nevada, CA.
University of Montana & USFS Region 5 2007-present
We are quantifying the relative role of anthropogenic, climatic, and biotic influences on fire probability in the western US using multiple modeling approaches. We are also studying the transformation, loss, and recovery of forest carbon resources due to management and wildfire.
Modeling and mapping vegetation across environmental gradients
University of California Davis 2004-2009
We developed improved strategies for modeling and mapping plant species distributions, vegetation structure, and biomass using species distribution models and high resolution satellite imagery (pixel resolution ≤ 1m2). We developed techniques for identifying individual tree crowns within high resolution imagery and pattern recognition techniques to identify forest stands, and vegetation patches of homogeneous physiognomy, structure, and floristics.
