I was just reading about this today: Mountain pine beetle effects on fire behavior... not a new article (it's news to me though).  

smiley_book2_page Well, it doesn't conclude much, except that they know how to start a forest fire (pictured in the article), I'm kidding, but there's more recent information about this kind of fire behavior on PubMed Central (PubMed includes articles about ecology). One says that such assumptions as those in the article above have been refuted: Area burned in the western United States is unaffected by recent mountain pine beetle outbreaks.

Alrighty, well I'm glad I found out about it later than sooner. Not that it seems totally implausable, still. It may or may not result in greater fire severity (they weren't sure). There's probably another article about that...

Right, here's one: Recent mountain pine beetle outbreaks, wildfire severity, and postfire tree regeneration in the US Northern Rockies

They found that "prefire mountain pine beetle outbreak severity affected few measures of wildfire severity", although after 3 to 10 years following a beetle outbreak, the surface fire severity may increase under extreme conditions, and result in more live trees being burned, because there is more fuel for the fire on the ground, from those beetles killing some of the surrounding trees.

The initial article predicted this to some extent, because dead pine needles that accumulate on the surface are drier and ignite more easily.

So, I was wondering if there was anything good that could come of pine beetle "outbreaks", and they do seem to have an ecological function, based on another article: Rapid Increases in Forest Understory Diversity and Productivity following a Mountain Pine Beetle (Dendroctonus ponderosae) Outbreak in Pine Forests...

"Within four years following beetle outbreak, productivity of understory plant communities increased along a gradient of beetle-induced tree mortality. Richness and evenness of herbaceous species also increased along the gradient of tree mortality while woody species richness and evenness did not."

I guess it's considered an outbreak then because the woody species don't benefit from it, and only people are supposed to keep those fires going (irrespective of their ecological impact).

Today I learned that forestry is kind of boring when I talk about it (so I'll just stick to yardwork).

Oh yeah. Interestingly enough, the yardwork turned into forestry on me anyway, when I found trees growing out of the rain gutters!
How does that go? Make like a leave and tree... fly_smiley

Had to go look and check the east gutter to see if remembered to log it this summer.  Have a maple tree off that side of the  house. That's just a type ornamental forestry anyway isn't it. Redneck Bonsai, at least that's my story.
