How do you like your silviculture served? In a book, a pamphlet, a video, or an app?

My office shelves are lined with decades-old research reports, mostly left behind by my predecessors; and having neither the time to sort through them nor the ability to fully shake my packrat tendencies, I hang on to them. Besides the information they contain, these volumes form a historical record of sorts, and so while they don’t come off the shelf too much these days, they are worth keeping around.

An example is Douglas-fir: Stand Management for the Future (1986). The title makes me consider whether the Future of Douglas-fir stand management has turned out the way the authors expected, when this was published nearly 30 years ago. Continue reading

Our Master Woodland Manager trainee class wraps up next week, after sixty-plus hours of learning and sharing together over the past six months. As an instructor, what I’ve enjoyed the most of this experience is that over half of our instructional time has been spent in the field, doing hands-on activities designed to encourage critical thinking about the day’s topic.

For each class session, we’ve tried to hone in on a few key themes. One theme for our forest health session was the importance of being observant in diagnosing a pest or disease. Our instructor, Dave Shaw, had the class look methodically for signs and symptoms at each site we visited. Where on the tree is the problem noticeable? Was there a pattern to the damage across the stand? What’s going on at the ground level? Any signs of chewing, wounding or scraping? What else is going on in the area?

Twice that day, we learned how easy it can be to prematurely jump to conclusions about a forest health problem, without pausing to get the full picture of what’s going on around you. We went to one site where there was extensive mortality of young Douglas-fir trees. Knowing that laminated root rot is the #1 most common disease in the area, when we walked into the stand and saw symptoms consistent with laminated root rot, most of the group who had seen it before agreed that it was the likely cause. But it was not until we started excavating around some of the dead trees that we found signs of two other root diseases, as well. Continue reading

In one word, what’s this a picture of?

Last month, the Port of Portland rejected a billboard that was proposed for the Portland airport. “Welcome to Oregon: Home of the Clearcut”, reads the ad, developed by a coalition of groups that oppose legislation that would increase timber harvests on federal lands. Now a subject of a free-speech debate, the fate of the billboard is unclear.

The billboard is meant to be provocative. But what interests me more than the billboard itself, or even the purpose behind it, is the public’s reaction, as expressed in various Letters to the Editor in the Oregonian. These letters reveal wide-ranging perceptions of what forests and forestry are (and aren’t). Continue reading
