Mongabay: New study identifies mature forests on U.S. federal lands ripe for protection

Forest ecologist Dominick DellaSala of Wild-Heritage in Oregon has been eager to produce high-quality, verifiable maps of remaining intact, mature and old-growth forests across the continental United States. He and I have been discussing the potential for such mapping to help create what he and colleague Bev Law of Oregon State call a Strategic Carbon Reserve, akin the the Strategic Petroleum Reserve that presidents call upon when gas prices spike or OPEC suppliers manipulate global oil supplies.

The carbon reserve would act as a protected carbon sink in the US that would remain intact, biodiverse and capable of continuing — and even expanding over time — its capacity to sequester greenhouse gases to help slow the rate of global warming. This story here describes the outcome of a new study (October 2022) in which DellaSala teamed with a group of forest ecologists to produce the first ever coast-to-coast mapping of such valuable, vulnerable forests.

President Biden in April 2022 requested similar mapping from his departments of Interior and Agriculture for the purpose to protecting more forests on federal land to help him meet his Paris Agreement GHG-reduction goals by 2030. DellaSala’s study will serve as a baseline comparison in April 2023 when the federal maps are due to make sure timber interests and forestry corporations don’t pressure the U.S. agencies to produce maps more favorable to logging than conservation.

While national park forests are fully protected, just 24% of U.S. Forest Service and Bureau of Land Management forests are fully protected, with the rest at various levels of risk.

Mongabay: British Columbia delays promised protections as old growth keeps falling

In summer of 2021, during a trip to the Pacific Northwest, I had hoped to continue my coverage of British Columbia’s at-risk old growth forests. But Covid-19 restrictions kept me from entering Canada. In July 2022, with the border re-opened, I was able to report this story from the field in Vancouver Island’s wooded and extensively harvested remote outback.

What I observed was both staggering and disheartening — large blocks of old-growth forests that should have been protected from logging, given a policy promise in 2020 by BC’s majority party, were being clearcut throughout southern Vancouver Island. Logging rushed to take down ancient giants while they still could. Torrance Coste, a BC forest campaigner, was my tour guide that day, taking me to settings of environmental degradation and decimation that few BC residents, let alone legislators, ever seen. They should. Torrance is also seen in a short video embedded in the story in which he explains the difference between native forests designed by nature and monoculture tree farms planted by logging companies.

The story is thorough and nuanced with politics, environmental science and the treatment of Indigenous peoples overlapping; I appreciate my editor Glenn Scherer giving me the space I needed to tell the full story. As a key source told me in the BC capital of Victoria:

“Certain politicians say, ‘Canada is just 1% of global emissions; it doesn’t matter what we do. But if we protect our at-risk old growth, we can be 10% of the global solution. Why don’t we want to be the beacon of what’s possible? Wouldn’t that be nice?”
