Land and Ecosystem Management



Our Mission
Our work is designed to increase understanding of terrestrial, aquatic, and riparian ecosystems and their linkages to inform management and policy options and develop tools to enhance or maintain the production of desired goods and services.

Our team research addresses the following problems, with many studies spanning several problems:

Problem 1: Improve knowledge of terrestrial, aquatic, and riparian ecology and their linkages essential for managing these ecosystems

  1. We develop aquatic biodiversity information to inform management of riparian areas: Biogeoclimatic impact on productivity and life history traits of aquatic species
  2. We explore factors that regulate food webs in lentic systems: Relationship of fish behavior and growth to resource availability and riparian inputs into that availability
  3. We improve knowledge of ecosystem processes essential for restoration of ecological functioning in late-successional and old-growth ponderosa pine forests: Effects of reintroducing fire in eastside ponderosa pine forests
  4. We integrate knowledge of natural and human-caused disturbances with poorly-defined shifts in regional climate to better understand and predict future forest structure and composition: Forest dynamics after thinning and fuel reduction
  5. We advance knowledge of the causes and consequences of microbial functional diversity to better predict responses to environmental change: Phylogenetic approaches to functional diversity of mycorrhizal fungi: linking environmental change to ecosystem function
  6. We explore the role of wildlife in the distribution of fungal species: Fungal biodiversity and community dynamics in the Oregon Coastal dune ecosystem
  7. We improve knowledge of the role of fire severity on establishment and growth of both soil microbial communities and non-native plant species: Invasive plant species and soil microbial response to wildfire burn severity
  8. We expand knowledge of the linkages between high severity fire and soil productivity: Effects of wildfire burn severity on soil microbial communities and other biogeochemical properties

Problem 2: Develop integrated management alternatives to provide for desired goods and services

  1. We quantify the consequences and tradeoffs of alternative fire and fire surrogate treatments: The National Fire and Fire Surrogate Study
  2. We improve information essential for site-specific silvicultural prescriptions for regenerating white spruce in Alaska: Regenerating white spruce in boreal forests of Alaska
  3. We explore opportunities and trade-offs for the production of economic, ecological, and societal benefits associated with thinning: Density Management and Riparian Buffer Study: Microclimate and Microsite Component
  4. We demonstrate alternative harvesting treatments that create or retain habitat for late-successional and old-growth dependent wildlife species: Siuslaw Thinning and Underplanting for Diversity Study (STUDS)
  5. We compare treatments designed to meet concurrent ecosystem restoration and fire risk objectives: Timbered Rock Reforestation, Stand Development and Fuels Study (TRock)

Problem 3: Create and refine models, databases, and tools to evaluate management alternatives

  1. We develop new metrics to quantify juvenile salmonid abundance and productivity, and extend effectiveness monitoring beyond numerical censuses: Fish population and life history response to habitat restoration
