What are the climate impacts of a given farm practice? While we know lots of strategies for reducing greenhouse gas emissions on farms, quantifying that impact can be difficult. However, there is at least one farm in our region – one that uses some pretty neat practices – for which scientists have attempted to answer that question. And the farmer just happens to be a long-time member of the Center for Sustaining Agriculture and Natural Resources’ advisory committee, Dale Gies. Continue reading

Biochar as a soil amendment has been the subject of much attention in recent years because of its ability to sequester carbon and to improve aggregation, water holding capacity, and organic matter content of soil amended with it (Lehmann, 2007; Marris, 2006). A recent post discussed what’s needed to economically produce forest to farm biochar. In contrast, researchers at Washington State University are investigating what we could call waste to farm biochar. Waste to farm biochar, if deployed on a larger scale, could offer a two-part benefit – removal of wood from the municipal solid waste stream and creation of a valuable product from this wood. In recent work, researchers are looking at two possible wastes that could be made into biochar: wood-based fractions of municipal solid waste and the large woody material remaining after compost production—referred to as “compost overs.”

Yes, more on snow… because there’s less snow. Read Nathan Gilles’s article in the Climate CIRCulator, that discusses research that found that mountains in the western United States have seen snowpack decreasing by an amount similar to the size of Lake Mead over the last 60 years.
Matt Reeves USFS Rocky Mountain Research Station and Georgine Yorgey Washington State University will present Case Studies to Build Rangeland Resilience
Cow-calf operators, the primary users of rangeland resources throughout the Pacific Northwest, will need to adapt to a range of future stressors, including those that are climate-related. A critical aspect of preparing for the future is understanding past vegetation performance and management responses. Learning from successful techniques for dealing with extended drought or reduced forage conditions can add insight to the future. Thus, as part of this project, we use case studies to quantify decadal trends and inter-annual variability for rangelands to aid managers and producers in planning for the future. We also profile forward-thinking grazers to provide stakeholder-centered and science-driven insights into their management practices to enhance resilience.
Friday, June 1, 2018 1 pm Eastern/12 pm Central/ 11 am Mountain/ 10 am Pacific
The presentation will follow an update on USDA Forest Service and Climate Hub activities

Remember 2015? That was a snow drought. Since then, researchers at CIRC (Climate Impacts Research Consortium) have been delving into snow droughts. They are part of an effort that recently released “a number of snow drought monitoring tools designed for decision makers and resource managers to monitor, plan for, and cope with snow drought and its impacts.” Get more details through Christina Stone (NIDIS) and Nathan Gilles’s article in the Climate CIRCulator, or check it out for yourself on the Snow Drought website.

My colleagues kicked off a discussion on biochar with their recent articles. Biochar can potentially be a win for soil health, for carbon sequestration in soils, and for fire risk reduction in forests. Kristin Trippe talked about the benefits of biochar as soil amendments in agricultural soils, and a tool to help producers choose biochar products. Chris Schnepf and Darrell McAvoy discussed the benefits and challenges of using forestry slash to produce biochar, and how mobile kilns can facilitate that. So, if biochar has all these benefits why aren’t all farmers spreading biochar on their fields? And why isn’t all the biomass from thinning being processed into biochar? Continue reading

Interested in better understanding climate change impacts in the Pacific Northwest? Our colleagues at CIRC (Climate Impacts Research Consortium) have recently released a report on their first seven years of research. Check out Nathan Gilles’s article on this report, that walks you through and highlights the key findings. Read Nathan’s article in the Climate CIRCulator.

Biochar has many possible agricultural benefits. Given the large role that fire plays in western forests, biochar has likely also already played a significant role in Northwest forests, as evidenced by the charcoal commonly found on top of or buried in our forest soils. Biochar shows promise in providing additional benefits in restoring heavily disturbed forest sites, such as forest roads, skid trails, and landings. For more information, see a chapter in a recent biochar book detailing the current state of North American forest biochar research.
Most of the enthusiasm around biochar in the forestry community, however, is related to using forest management residues to create biochar and useable fuels, such as bio-oil and syngas. Continue reading
