Feds to spend $30M on forest restoration projects

The USDA is kicking off a number of forest restoration project this year. There’s nothing major in this neighborhood, apparently, but that may change in subsequent years . . .

The U.S. Department of Agriculture said Thursday it will spend $30 million this year on forest restoration projects in 12 states to reduce the threat of wildfires, protect water quality and improve wildlife habitat for at-risk species.

Those first 13 projects will be the start of a multi-year initiative to improve the health of forests and watersheds on public and private lands, Agriculture Undersecretary Robert Bonnie said.

With longer fire seasons in recent years burning more areas, and beetle outbreaks devastating more than 40 million acres of forests in the West, the pace and scale of restoration need to be increased, he said.

Larger, hotter wildfires the new normal

Expect more big wildfires for a while . . .

The trend toward larger, hotter wildfires in this part of the country is rapidly becoming the new normal.

In the four decades between 1960 and 1999, wildfires in the United States scorched more than 7 million acres in a single year just once. Since 2000? Eight times, with 2012 at 8.8 million acres and still climbing. The annual number of wildfires exceeding 25,000 acres in 11 Western states has quintupled since the 1970s, according to a Climate Central report released last month.

The causes, fire ecologists say, are simple enough. A century of fire suppression and traditional “pick-and-pluck” logging practices that removed the largest, most fire-resistant trees have transformed open stands of ponderosa pine into multi-tiered, lower-crowned forests of thinner-barked trees more susceptible to spruce budworm and bark beetle — and catastrophic wildfire.

Recent study shows beetle-killed pine needles burn 3 times faster than live needles

That beetle-killed trees burn faster than live ones seems rather obvious, but it’s good that someone has come up with some hard numbers . . .

A recently study should put to rest the notion that green lodgepole pine needles burn as fast as red ones.

But more than that, Matt Jolly said, the study could help open firefighters’ eyes to the dangers lurking in mountain pine beetle-infested forests where the trees still look to be alive and doing well.

Bugs, fire, politics to transform western Montana forests

Here’s a pretty good discussion of the impacts on Montana’s forests over the next 50 years or so. Interestingly, some of the changes may actually restore earlier, healthier conditions . . .

Three things will combine to radically transform Montana forests in the next 50 years: bugs, fire and politics.

Mountain pine beetles have killed millions of acres of lodgepole pine trees. Those dead stands, combined with a progressively drier climate, will likely burn in wilder, more intense fashion. The biological aftermath should bring a wider mix of tree species, open areas and wildlife habitat, according to new computer models.

How humans tinker with that progression remains a wildcard…

New USFS study shows beetle-killed trees ignite faster

Here’s official support, with actual numbers, for something that seems intuitively obvious . . .

The red needles of a tree killed in a mountain pine beetle attack can ignite up to three times faster than the green needles of a healthy tree, new research into the pine beetle epidemic has found.

The findings by U.S. Forest Service ecologist Matt Jolly are being used by fellow ecologist Russ Parsons to develop a new model that will eventually aid firefighters who battle blazes in the tens of millions of acres from Canada to Colorado where forest canopies have turned from green to red from the beetle outbreak.
