Halofsky, Jessica E.; Peterson, David L.; Dante-Wood, S. Karen; Hoang, Linh; Ho, Joanne J.; Joyce, Linda A., eds. 2018. Climate change vulnerability and adaptation in the Northern Rocky Mountains (Parts 1 and 2). Gen. Tech. Rep. RMRS-GTR-374. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station.

Foresters were among the first to start thinking about the possible effects of climate change, in part because of the long-term nature of forests—foresters commonly reflect on management issues on 50 or even 150-year time scales. Because forests are also highly valued for other benefits in addition to commodity production (i.e., wood), those managing forests are also particularly aware of the long-term effects of their management on water, wildlife, soil, and other ecosystem benefits.

One of the best examples of that broad, long, view is a recent new publication titled “Climate Change Vulnerability and Adaptation in the Northern Rocky Mountains,” a two-part, 495-page document produced by the USDA Forest Service). The publication is the result of a process that had extensive involvement from Forest Service personnel, non-governmental partners, and universities in a series of 2- and 3-day workshops throughout the Northern Region of the Forest Service (including one in Coeur d’Alene, Idaho).

I recently enlisted colleagues to write a blog article about the impact carbon dioxide emissions have on the Pacific Northwest oyster aquaculture industry. While reviewing the blog I realized that ocean acidification is probably a little-understood feature for many of us.  Therefore, I went in search of articles and videos that explain the science of ocean acidification, and its impact on ecosystems and economies.

Climate change is expected to increase the vulnerability of our agriculture and natural resource systems. In the face of more extreme and variable weather, there are a suite of soil health management practices that land managers can adopt to build greater resilience and to reduce risks in their agricultural operations (examples of strategies in Figure 1).

Through engagement with land managers and those who work with them, including Extension, Natural Resource Conservation Services (NRCS), and Soil and Water Conservation District (SWCD) professionals, it became clear that many of them were interested in soil health and its linkages with climate change adaptation and mitigation. As a result, Oregon NRCS and the USDA Northwest Climate Hub partnered to develop a resource to aid advisors and land managers in discussing soil health and climate resilience together.

What Does Winter Wheat Decomposition Have to Do with Climate?

Leave a reply

by Georgine Yorgey

Managing crop residue is essential to reduced and no-till farming systems. These farming systems store more carbon than conventional farming systems, thereby mitigating climate change, enhancing soil health, and reducing soil erosion. In work described in a recent project report, Arron Carter and colleagues have been working to make it easier for growers with diverse needs across the Pacific Northwest to manage wheat residues. While the work is still in progress, it is an illustration of the kind of creative, applied work that is needed to make reduced-tillage systems easier to manage, and more widely adopted across the region.

Chances are that, when you go to a restaurant for oysters in the Pacific Northwest, you’ll come across a menu that features the Pacific oyster. Also known as the immigrant oyster, the Pacific oyster made its way to the Northwest in the early 1900s from Japan, and has remained a staple in aquaculture in the region due to the ease with which growers can produce the oyster and the value it holds in markets.

Over the past decade the oyster industry in the Northwest has taken a hit. Due to rapidly changing ocean conditions, a growing process that once ran like clockwork has been experiencing major glitches, and public enemy number one is ocean acidification. Continue reading →

Keeping Unusual Weather in Perspective While Looking Forward to the Growing Season

With the arrival of the spring equinox, many of us in the Pacific Northwest were still digging out from the snow or dealing with seasonal flooding, the impacts of a cold and snowy winter fresh in our minds. Just a couple of weeks later, news of the fire season is already starting. Along with fire and drought, extreme weather events are happening more frequently than historical records suggest. I’ve been surveying the state of weather-related affairs across the region, and summarize here some of the conditions relevant to agriculture. Continue reading →

Check it out: How to Reconcile 2019’s Unusual Winter with a Warming Climate

Now that spring is here and the cherry trees are starting to bloom, take a few minutes to check out John Abatzoglou’s article in the latest Climate CIRCulator’s Northwest Climate Currents. By relating the conditions the Northwest experienced this past February and March (and the earlier mild times we had in December and January), Dr. Abatzoglou puts our winter in context. He also explains the weather patterns that were responsible for the low temperatures and widespread low-elevation snow we saw, and why they occurred. He then goes on to discuss the broader context of how to reconcile these experiences with our understanding of how the climate is changing. Because I find this particularly fascinating, and feel it is important to hear what the experts say about it, I repost that portion of Dr. Abatzoglou’s article below, with some revisions he kindly made so that it does not feel like an excerpt (thank you, John). Read on to get a better handle on this apparent contradiction.

The Devil is in the Process: Co-composting Biochar Could Benefit Crop Growth and the Environment

Leave a reply

By Karen Hills

Biochar has the potential to sequester carbon and improve the properties of soils when used as an agricultural amendment. However, biochar will only be a viable option for carbon sequestration if there are uses and viable markets for this biochar. In recent years, there has been interest in adding biochar to agricultural soils in conjunction with compost, and in some cases, “co-composting” biochar—putting the biochar in with the feedstock before the composting altogether. Read on to learn about a study led by Dr. David Gang, a professor at Washington State University’s Institute of Biological Chemistry, indicating that co-composting can provide additional benefits, both during the composting process and to the crops grown in soil amended with the resulting co-composted biochar.

If you live in the Northwest, you either experienced first-hand or certainly heard about this past week’s blizzard in eastern Washington State.  This area does not usually get much precipitation over the course of a year.  During the winter, they may typically get a few inches of snow in any given storm. This storm, however, took many people by surprise and dumped 2-3 feet of snow in parts of eastern Washington, while bringing in winds from the east and temperatures in the low teens. Over 1,600 dairy cows were killed in this freak blizzard. At an estimated $2,000 per head, that is a loss of $3,200,000, spread over a little more than a dozen farms. That is huge unforeseen expense for struggling farmers to absorb, and a large amount of dead animals to dispose of safely.

USDA SARE (Sustainable Agriculture Research & Education) recently published a new resource for land managers and those who advise them titled, “Cultivating Climate Resilience on Farms and Ranches.” This resource outlines some of the challenges that farmers and ranchers will face as climate change leads to more extreme and variable weather. While the resource is national in scope, there is a great table that briefly explores the observed and expected changes in weather across seven U.S. regions, including the Northwest (Table 1).
