Bloomberg News has a pretty good article today:
Scientists Are Trying to Make California Forests More Fire Resilient
As the threat of wildfire looms, a debate has emerged in the state about the best way to plant trees.
Some interesting photos, too.
As someone who helped with numerous timber sales on the El Dorado NF in the 1980s, and helped suppress a few wildfires there, I agree that broad landscapes of plantations of evenly spaced trees are far from natural, and in a changing climate, perhaps are a liability — unless they are managed to be more like natural stands, with groups of trees and spaces in between. That can be done with “industrial” plantations, if thinning aims to leave groups/skips/gaps rather than maintaining relatively uniform stem density. Of course, this is site-specific. In some areas, even-aged, production-oriented silviculture is appropriate, and in other areas, nature has created dense, even-aged stands on its own. In between, group planting may help guard against the incineration of entire watersheds. Here is where desired future conditions, with due recognition of likely future climate conditions, might best guide management.
My headline would have been “humans disagree about how much planted trees should be clustered in the Sierra” : interesting quote..
I’m pretty much with Butler on this..
This is a classic problem.. we have no clue which will be best in reality (who knows if the climate will change so much that all the seedlings will die?) so different people make different assumptions. Then there’s another possibility.. start them to maximize growth and then thin to clumps based on what we know then. That would soak up most carbon right now, plus you would have whatever clumps you want designed with whatever you think is best at the time (20-30 years from now we’ll know a lot more about everything and we might even have markets for the material).
Everyone’s experience is different and every site is different .and that’s a good thing about people trying different things and seeing how they work IMHO..
