Selection cutting: Panacea or damage in disguise?

t’s not difficult to convey the environmental impacts of clear-cut logging; just look at the big, ugly bald patches of scarred earth after a clear-cut and you get it. But too often, an alternative to clear-cutting — known as selection logging — is offered as a panacea. Wow, it looks so much better than a clear-cut, especially when you’re looking at photos taken by timber companies doing the logging.

But if you get down into the weeds, so to speak, as forest scientists do, you start finding that selection logging also has problems…they’re just not as visible. One of the biggest problems of selection logging is the ground disturbance from the haul roads and skid trails cut into the forest to take the trees out.

Is wilderness real? Is it worth restoring?

One evening last fall I nearly had a panic attack as I read the now famous 2003 article, “Are You Living in a Computer Simulation?” by Nick Bostrom, a Swedish philosopher at the University of Oxford. Bostrom’s theory has convinced many physicists and futuristic thinkers like Elon Musk that the natural world — the Universe — is actually a computer simulation created by some advanced post-human civilization. I’m not exactly a sci-fi aficionado and I had to force myself to watch “The Matrix,” but Bostrom made a strong, logical argument that for a brief moment shook my life-long belief that nature is the baseline for everything else that exists.

As an environmentalist, I’ve always held to the notion held by deep ecologists that wild nature, as it evolved through the eons, needs to be preserved as the foundation for life on the planet. Wilderness areas (Earth’s least disturbed places) are a priceless storehouse of our planet’s biodiversity. We need to protect wilderness — or else humans, along with other species that we share the planet with — will perish.

Our undervalued natural resource

Our undervalued natural resource

We seem to be deluged with news lately about the dwindling water supply here in Santa Cruz County. Most has centered on ways to address the problem, especially the controversial proposed desalination plant vs. the need for more conservation. What's not at issue is that increasing water shortages are due to increased demand, longer dry spells, and the need to leave more water in the streams for native fish, especially endangered coho salmon.

What often seems left out of the conversation is just how precious our existing water supply is.
