Note, even the "good" brand can go rancid if you don't take care of your stash. I highly recommend cutting one open for a smell test if you're unsure. Also, if you're getting gross burps, your batch may be bad.
I've used Aqua Omega (unaffiliated) with great success for years.
These forests have been logged multiple times over history, and many were replanted with terrible replanting practices.
1. Monoculture, with a focus on economic species. This means that fire-resistant Alder (deciduous) that helps mitigate fires, are not planted.
2. Glyphosate bombing. Yes, we aerial bomb our forests with Glyphosate in order to kill of the Alder which fills in much faster than the desired economic species. I bet you didn't know that..
3. Trees were planted WAY to close together. Many of these forests looks like matchsticks, because that's what they are. At the time it was thought that closer-spacing would lead to faster harvesting and more biomass(money), but what you end up with is a giant tinderbox with small trees, TONS of deadfall.
What all this leads up to is way more fire frequency and a MUCH higher fire magnitude. Large healthy trees, with their canopies way about the forest floor, are naturally resistant to fires, even without Alder around. Once the fire reaches the canopy it will spread fast and far, and likely kill the tree.
