Putting Our Public Forests Into Carbon Reserves

The Biden Administration supports protecting 30% of US lands by 2030 or what is termed the 30 x 30 proposal. One of the best ways to meet that 30 by 30 goals would be to put all national forests and BLM lands off-limits to logging.
Not only does this help to move the country closer to the 30 x 30 goals, but it would go a long way towards sequestering carbon as well.
Our public forests currently hold about 7 times the current annual national carbon emissions and US forests sequester about 12% of the country’s carbon emissions.

If we stopped logging and thinning our federal forests, we could sequester even more carbon.
However, the Forest Service, the timber industry, and co-opted conservation groups continue to support thinning the forest in the name of precluding large wildfires.
Unfortunately, advocates of thinning mislead Americans on the limited effectiveness of thinning in precluding large blazes. Plus logging contributes more carbon to the atmosphere that exacerbates fire weather.

The problem with the thinning will limit large fires myth is that it ignores the influence of extreme fire weather. Thinning might, in some instances, slow or stop blazes burning under low to moderate fire conditions, but not under extreme fire weather. Under less than extreme weather, most fires are easily suppressed or even self-extinguish if we leave them alone.

All large fires are driven by extreme weather. And these are the fires that the agency, politicians and others seek to stop, but under such conditions, the scientific consensus is that nothing can stop a blaze. Wind-driven fires pass over, around, and through thinned forests and prescribed burning sites.
Second, there is a low likelihood that any treated forests will be exposed to fire. So most thinning projects remove carbon, but they do nothing to reduce large blazes.

As one study concluded: “the amount of carbon removed to change fire behavior is often far larger than that saved by changing fire behavior, and more area has to be harvested than will ultimately burn over the period of effectiveness of the thinning treatment.”
Another researcher suggests: “Reducing the fraction by which C is lost in a wildfire requires the removal of a much greater amount of C, since most of the C stored in forest biomass (stem wood, branches, coarse woody debris) remains unconsumed even by high-severity wildfires.”

The misconception that many hold is that fires release a lot of GHG emissions. Burning does release some carbon, but the majority of the carbon in the forest remains on site even after a severe fire. The snags left after a blaze contain much of the carbon found in a forest, while charcoal that is retained in the soil stores even more carbon.
By contrast, logging releases a tremendous of carbon.

That is one reason the biggest sources of Green House Gas (GHG) in Oregon is logging which accounts for 35% of the state’s emissions.
The other problem is that recovering that carbon lost during thinning/logging takes decades to centuries and we need to reduce carbon emissions now.

Surprisingly, many conservation groups, on hand claim that climate change is the biggest threat to the future of the planet, yet the same groups support thinning the forest in the name of fire exclusion and at times even burning logging residue for biomass energy.

The highest value of our public forests is their function as carbon reserves. Prohibiting logging would not only help sequester more carbon, but provide numerous other benefits such as watershed protection, protection of wildlife habitat, preserving the ecological function of insect, wildfire, and drought that creates healthy forest ecosystems.

Ironic that in logging & “thinning”, in order to reduce fires – the carbon released in those efforts is more than what the fires would cause to be released! Sort of 2 steps forward & likely 2 steps back. Appears that now is the time for our government & lawmakers to be awakened to true facts rather than profit and the bottom line.
Since the Reagan/Watt years less and less regulation by the federal government has perpetuated a permissive attitude toward businesses that utilize resources on public lands so that damage to public land has largely been overlooked. This operational paradigm has created a mythos of economic success while at the same time building up an extensive back log of ecological damage.
How long can the government permit fracking when fracked wells require anywhere from a quarter million to 15 million gallons of fresh water per well? And how long can biofuels power generation continue when it is 1.5 times more polluting than coal and 3 to 4 times more polluting than natural gas. (see the work of Mary Booth for the facts) EG: https://docs.cpuc.ca.gov/PublishedDocs/SupDoc/R2011003/3350/360565082.pdf
The United Sates has dug itself into a very deep hole of environmental degradation and economic instability. Will the Biden administration have the intelligence and fortitude to carry out the necessary regulation to reverse environmental/economic damage and what will be the result if it cannot?
You ask “Will the Biden administration have the intelligence and fortitude to carry out the necessary regulation to reverse environmental/economic damage, and what will be the result if it cannot?”
I think Biden’s appointments and nominations look very good compared to the past, including the Obama Administration. The biggest block in environmental regulation will hardly be the new Biden Administration.
The blockade will come from the dysfunctional, mixed up, partly seditionist Republican Party. People who believe in QAnon, will not be supporters of taming climate change.
Biden have to fight hard to get all of his environmental team past the Republicans in the U.S. Senate.
