Ongoing Projects

Oriented by three research thrusts we work in partnership with communities, industries, NGOs, local governments, and federal agencies to coordinate research on climate mitigation and adaptation. Examples of our recent collaborative work include:

1. Enhanced Natural Climate Solutions (NCS+) using case studies from the Pacific Northwest of the USA as a model temperate system (Research funded by NSF, USDA, and industry partners):

Landscape opportunity mapping for increased carbon drawdown and permanence using ecological and geological datasets.

Using geomorphic landforms to map and forecast soil organic carbon in montane landscapes. Preliminary data presented by PhD candidate Brooke Hunter at AGU 2021 show large potential for carbon accumulation using terrace age power law relationship for an inventory of ~10,000 dated landslide chronosequences in the Oregon Coast Range https://agu.confex.com/agu/fm21/meetingapp.cgi/Paper/817129

Field experimentation for the artificial selection of plant and microbial communities that accelerate carbon stabilization in agricultural soils.

Designing novel plant and microbial communities using stable isotope probing and artificial selection under field conditions. Preliminary data presented by PhD student Hillary Rose Dawson at Botany 2021 show scaling functions for morphological and functional species traits that control carbon, nitrogen, and water transfer in root-mycorrhizal networks (http://2021.botanyconference.org/engine/search/index.php?func=detail&aid=89) and in paired experiments across a 520-km latitudinal gradient in WA and OR. This research involves co-production of knowledge with local stakeholders to explore the effects of plant community composition on carbon markets http://2021.botanyconference.org/engine/search/index.php?func=detail&aid=1046.

Quantification of wildfire effects on ecosystem carbon stocks and the potential for prescribed fire in stabilizing soil carbon pools.

Quantifying soil carbon dynamics after low-intensity (prescribed) and catastrophic wildfires in OR and CA.Preliminary data presented by PhD candidate Jamie Wright at AGU 2021 show a surprising trend of carbon accumulation in areas affected by fire compared to controls https://agu.confex.com/agu/fm21/meetingapp.cgi/Paper/907861

2. Enhanced Natural Climate Solutions (NCS+) using case studies from central Brazil as a model tropical system (Research funded by NSF, National Geographic, and industry partners):

Regional opportunity mapping using social, ecological, and geological datasets to inform policies and align incentives for biodiversity conservation and carbon sequestration.

Field experimentation using waste materials to reset natural succession and increase carbon stabilization in severely degraded landscapes.

Quantification of management effects on soil carbon and nutrients and the potential for indigenous land management in improving carbon stocks while sustaining livelihoods in nutrient-poor regions.
