The Pacific Northwest Research Station's Biodiversity Initiative: Collaborating For Biodiversity Management

The Pacific Northwest Research Station launched a Biodiversity Initiative to assist natural resource professionals in integrating complex biodiversity concepts into natural resource management processes. We canvassed clients from various affiliations to determine the main challenges they face in biodiversity management, to define their information needs, and to understand how best to deliver biodiversity information within a collaborative framework. The biodiversity management challenges that emerged included (1) the lack of well-defined biodiversity management policies, (2) understanding and quantifying the interaction effects between a number of factors (e.g., disturbance types, management practices) and biodiversity, (3) the lack of applied biodiversity monitoring strategies, (4) difficulty in locating and accessing biodiversity information, and (5) balancing conflicting values relating to biodiversity. We also list the biodiversity information product needs of clients, as well as preferred technology transfer methods, and we discuss the future direction of the Biodiversity Initiative.

Potential vegetation hierarchy for the Blue Mountains section of northeastern Oregon, southeastern Washington, and westcentral Idaho

The work described in this report was initiated during the Interior Columbia Basin Ecosystem Management Project (ICBEMP). The ICBEMP produced a broad-scale scientific assessment of ecological, biophysical, social, and economic conditions for the interior Columbia River basin and portions of the Klamath and Great Basins. The broad-scale assessment made extensive use of potential vegetation (PV) information. This report (1) discusses certain concepts and terms as related to PV, (2) describes how a PV framework developed for the broad-scale ICBEMP assessment area was stepped down to the level of a single section in the national hierarchy of terrestrial ecological units, (3) describes how fine-scale potential vegetation types (PVTs) identified for the Blue Mountains section were aggregated into the midscale portion of the PV hierarchy, and (4) describes the PVT composition for each of the midscale hierarchical units (physiognomic class, potential vegetation group, plant association group).

Wood energy for residential heating in Alaska: current conditions, attitudes, and expected use.

This study considered three aspects of residential wood energy use in Alaska: current conditions and fuel consumption, knowledge and attitudes, and future use and conditions. We found that heating oil was the primary fuel for home heating in southeast and interior Alaska, whereas natural gas was used most often in south-central Alaska (Anchorage). Firewood heating played a much more important role as a secondary (vs. primary) heating source in all regions of Alaska. In interior Alaska, there was a somewhat greater interest in the use of wood energy compared to other regions. Likewise, consumption of fossil fuels was considerably greater in interior Alaska.

Seasonal neighbors: residential development encroaches on mule deer winter range in central Oregon.

Mule deer populations in central Oregon are in decline, largely because of habitat loss. Several factors are likely contributors. Encroaching juniper and invasive cheatgrass are replacing deer forage with high nutritional value, such as bitterbrush and sagebrush. Fire suppression and reduced timber harvests mean fewer acres of early successional forest, which also offer forage opportunities. Human development, including homes and roads, is another factor. It is this one that scientists with the Pacific Northwest Research Station and their collaborators investigated in a recent study.

Synthesis of wind energy development and potential impacts on wildlife in the Pacific Northwest, Oregon and Washington.

Nationally, there is growing public interest in and policy pressure for developing alternative and renewable sources of energy. Wind energy facilities in the Pacific Northwest expanded rapidly over the past decade, as a result of state policies that encourage wind energy development. While much of the development thus far has occurred on private lands, there is interest in expanding onto federal land. However, there are concerns about the impacts of wind energy on wildlife. Wind energy facilities have the potential to harm wildlife both directly through collisions with turbines and transmission lines, and indirectly by modifying habitat. This report synthesizes the available scientific literature on potential wind energy facility impacts to wildlife, with a focus on the Pacific Northwest (Oregon and Washington), and summarizes the current best management practices recommended in federal and state guidelines for wind energy development. Research gaps in our understanding of wind energy impacts on wildlife remain. Future research needs include long-term, multisite, experimental studies of wind energy impacts on wildlife, improved ability to estimate population-level and cumulative impacts of wind energy facilities on wildlife, and better knowledge of key wildlife species' migration and demography.

Exploring the role of traditional ecological knowledge in climate change initiatives

Indigenous populations are projected to face disproportionate impacts as a result of climate change in comparison to nonindigenous populations. For this reason, many American Indian and Alaska Native tribes are identifying and implementing culturally appropriate strategies to assess climate impacts and adapt to projected changes. Traditional ecological knowledge (TEK), as the indigenous knowledge system is called, has the potential to play a central role in both indigenous and nonindigenous climate change initiatives. The detection of environmental changes, the development of strategies to adapt to these changes, and the implementation of sustainable land-management principles are all important climate action items that can be informed by TEK. Although there is a significant body of literature on traditional knowledge, this synthesis examines literature that specifically explores the relationship between TEK and climate change. The synthesis describes the potential role of TEK in climate change assessment and adaptation efforts. It also identifies some of the challenges and benefits associated with merging TEK with Western science, and reviews the way in which federal policies and administrative practices facilitate or challenge the incorporation of TEK in climate change initiatives. The synthesis highlights examples of how tribes and others are including TEK into climate research, education, and resource planning and explores strategies to incorporate TEK into climate change policy, assessments, and adaptation efforts at national, regional, and local levels.​

Life cycle assessment of wood energy for residential heating—opportunities for wood pellet production in southeast Alaska.

Southeast Alaska is a remote area, located approximately 700 miles north of Seattle, Washington. Most of the region’s goods are imported by barge, creating logistical and economic challenges not faced by many other parts of the United States. In this context, we used life cycle assessment (LCA) to evaluate the potential environmental impact on global warming potential (GWP) of converting home heating systems from heating oil to wood pellets in southeast Alaska. Once the current level (status quo) was established, we evaluated imported pellet utilization at 20-, 40- and 100-percent penetration into the residential heating oil markets. We also modeled local production of wood pellets in southeast Alaska, assuming a 20-percent penetration. Our research found that reductions in GWP resulting from the conversion to wood pellets ranged from 10 to 51 percent, with the greatest reductions being associated with the highest levels of imported pellets. The scenario of producing wood pellets in southeast Alaska to meet local needs had a reduction in GWP of 14 percent (versus the status quo).

Ahead of VP Pence’s Iowa visit, Joe Biden’s campaign calls out ‘consequential failure’ of Trump coronavirus response

Vice President Mike Pence owes Iowans more than a photo-op when he visits Des Moines today, according to Joe Biden’s campaign.

“Iowans are seeing up close the most consequential failure of government in modern American history,” said Kate Bedingfeld, spokeswoman for the former vice president and presumptive Democratic presidential nominee.

“With nearly 300,000 Iowans filing for unemployment, rural hospitals on life support, Latino communities disproportionately suffering and workers on the job without sufficient protection, Mike Pence owes Iowans more than a photo-op — he owes them answers,” she said.

Pence, head of the White House coronavirus task force, is scheduled to meet with Iowa Gov. Kim Reynolds and U.S. Sens. Chuck Grassley and Joni Ernst, all Republicans, as well as with faith, farm and food production leaders.

Pence will talk to faith leaders about how they are using federal and state guidelines to open their houses of worship in a safe and responsible manner.

Later, he will go to Hy-Vee’s headquarters in West Des Moines for a roundtable discussion with agriculture and food supply leaders to discuss steps being taken to ensure the food supply remains secure.

Pence has called Iowa a “success story” in its response to the COVID-19, but Bedingfeld said the Trump administration failed to protect Iowa families from the virus that has claimed the lives of 231 Iowans.

“From devastating losses across the state, at meatpacking plants to rural communities, one thing is clear — it’s Iowans and the American people who are paying the price for the Trump administration’s denials and delays in response to this pandemic,” she said.

“Instead of listening to our own intelligence agencies and public health experts, Donald Trump was fed dangerous propaganda from the Chinese Communist Party — and he bought it,” she said. “Iowans deserve better — they deserve Joe Biden.”

For his part, Grassley said he welcomes the discussion with Pence.

“There’s much work to be done, and the pandemic is disrupting all of our communities,” Grassley said. “It’s important to hear directly from those who help feed the nation and the world.”

Ernst also is looking forward to the discussion of how Iowa is working to protect the health and safety of Iowa’s families and communities while reopening the state’s economy.

“We continue to take an all-hands-on-deck approach to tackling this pandemic,” she said. “Together, we will get through this.”

New machines in Test Iowa initiative still unproven

DES MOINES — More than 20 days after Iowa signed a $26 million contract with a Utah company to expand testing in the state, the machines the firm supplied to run the samples still have not passed muster.

A time frame for completing the validation process for the Test Iowa lab machines is unknown, as the process can vary by machine, University of Iowa officials said Friday.

The validation process is undertaken to determine if the machines are processing tests accurately. To this point, the lab has processed the Test Iowa results using machines the State Hygienic Lab already had, officials told The Gazette.

Running side-by-side testing is part of the validation process. The lab then compares whether the machines yield the same results when the sample is run, officials said Friday. The side-by-side testing means the Test Iowa samples are being run at least twice to compare results.

The state does not break out how many of the 331,186 Iowans who by Friday have completed the coronavirus assessment at TestIowa.com have actually been tested. Test Iowa was initiated last month to ramp up testing of essential workers and Iowans showing COVID-19 symptoms. The state’s fourth drive-though location where people with appointments can be tested opened Thursday at the Kirkwood Continuing Education Training Center in Cedar Rapids.

On Friday, Iowa posted a fourth straight day of double-digit deaths from coronavirus, with the latest 12 deaths reported by the state Department of Public Health bringing the statewide toll to 243 since COVID-19 was first confirmed March 8 in Iowa.

State health officials reported another 398 Iowans tested positive for the respiratory ailment, bringing that count to 11,457 of the 70,261 residents who have been tested — a positive rate of more than 16 percent.

One in 44 Iowans has been tested for COVID-19, with 58,804 posting negative results, according to state data. A total of 4,685 people have recovered from the disease.

During a Thursday media briefing, Gov. Kim Reynolds told reporters a backlog of test results that occurred due to validation of Test Iowa equipment had been “caught up,” but some Iowans who participated in drive-through sites set up around the state indicated they still were awaiting results.

Reynolds spokesman Pat Garrett confirmed Thursday that “a very small percentage” of coronavirus test samples collected under the Test Iowa program could not be processed because they were “potentially damaged,” resulting in incomplete results.

There were 407 Iowans who were hospitalized (with 34 admitted in the past 24 hours) for coronavirus-related illnesses and symptoms with 164 being treated in intensive care units and 109 requiring ventilators to assist their breathing.

Health officials said the 12 deaths reported Friday were: three in Woodbury County, two in Linn County and one each in Black Hawk, Dallas, Dubuque, Jasper, Louisa, Muscatine and Scott counties. No other information about the COVID-19 victims was available from state data.

According to officials, 51 percent of the Iowans who have died from coronavirus have been male — the same percentage that tested positive.

Iowans over the age of 80 represent 46 percent of the COVID-19 victims, followed by 41 percent between 61 and 80.

Of those who have tested positive, state data indicates about 42 percent are age 18 to 40; 37 percent are 41 to 60; 14 percent are 61 to 80 and 5 percent are 81 or older.

Counties with the highest number of positive test results are Polk (2,150), Woodbury (1,532), Black Hawk (1,463) and Linn (813).

Earlier this week, state officials revamped the data available to the public at coronavirus.iowa.gov, with the new format no longer listing the age range of Iowans who died from coronavirus and providing information using a different timeline than before.

The governor did not hold a daily media briefing Friday due to scheduling conflicts created by Vice President Mike Pence’s trip to Iowa. Garrett said Reynolds would resume her COVID-19 briefings next week.

John McGlothlen and Zack Kucharski of The Gazette contributed to this report.

Solutions for nonlinear Fokker-Planck equations with measures as initial data and McKean-Vlasov equations. (arXiv:2005.02311v2 [math.AP] UPDATED)

One proves the existence and uniqueness of a generalized (mild) solution for the nonlinear Fokker--Planck equation (FPE) egin{align*} &u_t-Delta (eta(u))+{mathrm{ div}}(D(x)b(u)u)=0, quad tgeq0, xinmathbb{R}^d, d e2, \ &u(0,cdot)=u_0,mbox{in }mathbb{R}^d, end{align*} where $u_0in L^1(mathbb{R}^d)$, $etain C^2(mathbb{R})$ is a nondecreasing function, $bin C^1$, bounded, $bgeq 0$, $Din(L^2cap L^infty)(mathbb{R}^d;mathbb{R}^d)$ with ${ m div}, Din L^infty(mathbb{R}^d)$, and ${ m div},Dgeq0$, $eta$ strictly increasing, if $b$ is not constant. Moreover, $t o u(t,u_0)$ is a semigroup of contractions in $L^1(mathbb{R}^d)$, which leaves invariant the set of probability density functions in $mathbb{R}^d$. If ${ m div},Dgeq0$, $eta'(r)geq a|r|^{alpha-1}$, and $|eta(r)|leq C r^alpha$, $alphageq1,$ $alpha>frac{d-2}d$, $dgeq3$, then $|u(t)|_{L^infty}le Ct^{-frac d{d+(alpha-1)d}} |u_0|^{frac2{2+(m-1)d}},$ $t>0$, and the existence extends to initial data $u_0$ in the space $mathcal{M}_b$ of bounded measures in $mathbb{R}^d$. The solution map $mumapsto S(t)mu$, $tgeq0$, is a Lipschitz contractions on $mathcal{M}_b$ and weakly continuous in $tin[0,infty)$. As a consequence for arbitrary initial laws, we obtain weak solutions to a class of McKean-Vlasov SDEs with coefficients which have singular dependence on the time marginal laws.
