This paper, in the July 2017 edition of the Journal of Forestry, may help us in our discussions of fuel-treatment effectiveness.
In the wrong place at the wrong time, wildfires cause damage to ecosystems and threaten homes, communities, and cultural resources. To manage the impact of future wildfire and help restore its natural role in forest ecosystems, land managers often use fuel treatments such as thinning, mowing, and prescribed burning. How well do these treatments work? Ecologist Nicole Vaillant studies fire behavior and fuel treatments, including how effective they are over time. Her work is important in helping land managers assess wildfire risk and compare different fuel treatment strategies. She recently led a study that addresses the question: Are we treating enough of the landscape to compensate for decades of fire suppression?
Vaillant and her coauthor, Elizabeth Reinhardt, evaluated the extent of fuel treatments and wildfire on all lands administered by the Forest Service from 2008 to 2012. They compared these areas with historical wildfire rates and severities; they found that each year only about 45 percent of the area that would have burned historically experienced either characteristic wildfire or fuel treatment. This indicates a “disturbance deficit.” The good news is that 73 percent of the acres burned by wildfire during this period experienced characteristic fire (wildfire at an appropriate severity level for that ecosystem). However, Vaillant’s study also found that the forest type in the highest wildfire hazard class had the lowest percentage of area treated and also the highest proportion of uncharacteristically high-severity wildfire. This suggests that locating more treatments in areas with the highest hazard could improve program effectiveness. This is the first study to intersect the actual footprint of fuel treatments and wildfire with mean fire-return interval and wildfire hazard on a national scale.
This doesn’t surprise me, because my experience has been that, other than WUI, there has been very little prioritization of where to put fuels treatments on the ground, or, if fuels treatments are part of a larger project area, no prioritization within the project area. The FS is a “widget production” – driven organization in many ways, and since burn windows are relatively unpredictable, and the overall “reward” is for number of acres treated, one acre is as good as any other acre and burning piles is just as good as a prescribed burn, which is just as good as mastication. And, there is that implicit assumption (that is likely incorrect) that there is a linear relationship between the total number of acres treated and the effectiveness of the treatment. So the focus is on overall acres…Plus there is the misguided perception that “integration” means doing everything in the same place at the same time, when, in reality, the highest priority areas for fuels treatments, forest restoration, watershed restoration, etc. are not all in the same place/project area. There are ways to deal with this, but much of the FS, due to reduced staffing, has bought into the idea that the most “efficient” way to do NEPA is on large areas (50,000 acres +), and they only have the staff to “plan” one of these areas at a time. And those areas are usually selected based on the availability of wood products, as keeping the mill infrastructure and jobs associated with that are generally a higher priority.
Agree on the need for prioritization.
However, we must also balance the need to sustain forest industry infrastructure if we are to control the cost of such treatments in order to treat significant acreage.
Thanks for the insightful comments, mom. They shine the light on the lack of transparency of the “decisions” that occur between the forest plan and projects and establish the actual priorities for national forest management. It could help improve effectiveness and accountability if the Forest Service would include the public in this part of the process and disclose its rationale.
Here is a related publication showing that the stands the most need fuel treatment are full of tiny trees that won’t support a viable timber sale. The emphasis of the Forest Service is to pretend there is near perfect alignment between fuel reduction and commercial logging. It’s folly to set fuel reduction priorities based on commercial viability of fuel reduction logging.
“Hoping to boost their economies and also restore these forests, local leaders are interested in the economic value of timber that might be available from thinning treatments on these lands. … [W]e found that on lands where active forestry is allowable, thinning of most densely stocked stands would not be economically viable.” Rainville, Robert; White, Rachel; Barbour, Jamie, tech. eds. 2008. Assessment of timber availability from forest restoration within the Blue Mountains of Oregon. Gen. Tech. Rep. PNW-GTR-752. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 65 p. http://www.fs.fed.us/pnw/pubs/pnw_gtr752.pdf
Most of the forests that need restoration will not support a viable timber sale, so restoration will require investment, not profit taking. This very sobering report from PNW Research shows that commercial logging is not a good tool for restoration because it will be useful to address only a small fraction of the restoration needs in degraded forests with relatively low productivity like the Blue Mountains.
This confirms what we have known for years, that past management has taken too many of the big trees and left current managers with limited options. After being clearcut or high-graded in the past, and given the high production costs and low value of small logs, most dense over-stocked stands will not support a viable timber sale that still sustains the other important values in the forest. The report says that retained receipts will help some, but not much. And if the 21″ diameter cap in the Eastside Screens were lifted to make ‘restoration’ more profitable, no one can legitimately call it “restoration” anymore.
Too many people seem to be under the false impression that thinning is a magic bullet that will solve all our problems. Other forms of restoration such as prescribed fire and non-commercial thinning might make but funding will be a challenge. How will these action be funded if Congress is under a false impression that thinning is the universal antidote?
MORE EXCERPTS FROM RAINVILLE ET AL:
2ndLaw, there are forest products other than sawlogs. A few examples” Miller Timber, a contractor in the PNW, routinely takes material from thinning projects down to a 2-inch top, for pulp and fuel chips. Bear Mountain Forest Products in Cascade Locks, WA, makes wood pellets and bricks (fuels used in residential and commercial heating/power systems), and animal bedding, from small-diameter logs. Avista’s Kettle Falls, WA, generating station has been generating power from wood waste since 1983. More such plants might be opened if there were long-term contracts for woody biuomass — the stuff of thinning that is otherwise unmerchantable.

I won’t dispute your reference study but even if everything it says is true, then it tells us to prioritize our efforts on those areas where it is not true including Steve’s appropriate comments above.
