They should be investing their energy into finding a way to make better use of these small logs instead of wasting them like this.
Good lord, what bullshit. On top of the fact that it’ll get broken down anyway, you’ll just burn a few tons of carbon excavating and filling a hole.
There are several major problems this solves. The forests are overstocked, which is part of what leads to larger and more severe wildfire. These are live trees, and won’t break down, but need to be thinned. And if the forest does burn, that dead wood needs to be removed to prevent it from burning again. This wood could break down eventually, but it makes it riskier to replant (for both the people planting, and the new seedlings).
Both of these activities are incredibly expensive, and burying the trees in a vault on site could provide a way to manage all of the wood, and pay for it.
Should wood vaults be the only solution? Probably not. And we should definitely remain skeptical as they are proven out. But proper forest management is challenging, expensive, and is often neglected (at least in the US), and I think it’s overall beneficial to explore novel solutions like this.
Seems like biochar would be a better solution.
And did they consult the mushrooms ? Seems in medium term, may help feed a lot of bugs and birds, which is good for biodiversity, but to store carbon, needs to be fungi-proof.
Why not just stack the wood in arid places though?
Sink it in the deep ocean then, let’s see it burn there!!! Wait, what do you mean wood floats? Bah, details!
