In part two of his essay series on modern wildfires, Rex Sanders explores how backpackers must adapt to the new normal.
More on wildfires and local water pollution in this LA Times story from Santa Cruz County, California:
“Every storm that has occurred since the fire has caused the water to run black for a few days, so I know runoff is making it into the water”
A local water district is using groundwater instead of previously-better surface water, but that’s not sustainable during a long-term drought.
“We are learning that there’s a lot we really don’t know.”

What is the regeneration time for the flora typically?
Hiking the Angeles NF the past summer (PCT sections), I met another hiker claiming to have been a firefighter on one of those fires about a decade ago (+/-) who said the burnt area seemed far better off (assuming he meant in comparison when it actually wasn’t on fire). The big problem is the next few years is erosion as ecological succession takes place (first plant species to stabilize the soil -> helps support larger shrubs and trees later on). Other western areas used oats as an annual ground cover to assist soil reformation in the first year or 2 of recovery.
Of course California also had big winter rain years in 2017 and 2019 with a decent 2018 .. after several years of drought or dryness.
In brief: post-wildfire “recovery” is different everywhere, even within California, even within a mile or two.
Plus recovery can be measured in many different ways, and the metrics frequently don’t correlate. Fires can be patchy, vegetation isn’t uniform, animals aren’t uniform, water quality will vary, and geohazards like debris flows and landslides can be very site specific.
Even what helps in some places, like planting oats or other fast-growing plants, can be useless or detrimental in other areas.
As much as we might like simple answers, they are in short supply. If I could snap my fingers and return to a pre-industrial climate tomorrow, we’d still have serious wildfire-related problems in California for many other reasons.
