[FRIAM] Drones to detect wildfires

We won’t realize anything unless the experiments happen.   We may not learn from experiments, but that is a different issue than the need for the experiments.

My father dedicated his life to "forest management" as a professional forester, trained in biology and range/timber management.   He retired "early" after 30 years somewhat in disgust over the changing of aesthetics and perspectives of the United States Forest Service.   He was dedicated and loyal to the spirit of Aldo Leopold and other early conservationists.  He spent multiple multi-week segments every summer leading (most Zuni and Hopi native) fire-crews on the West Coast trying ot protec homes and "valuable timber". We lived on the edge of the first Wilderness (Gila) created (at the behest of Aldo Leopold) for 2/3 of my growing up years.   My father died 10 years ago (Alzheimers), was cremated, and we (illegall) spread his cremains in the heart of the Gila with a minor amount of guilt as he was a (nearly) strict rule follower (yet asked for this).   Within the year, a serious wildfire complex converged at almost the exact spot we scattered him (woooOoooooo!).

Even my Trump-voting (2016) sister and husband are now acknowledging that his life/profession were dedicated to a project that was fundamentally "unwise".    They *were* (for the most part) doing the best they knew how.  Most everything they did (from stopping wildfires at the first opportunity) to running dual bulldozers across landscapes with a chain between them to clear the juniper trees from a landscape to allow more grass (for cattle) to grow was "well intended", but it was *range* and *timber* management not "grassland" and "forest" management as they called it.  The goal was to maximize the "productivity" of the public lands under their management (dept of Agriculture_.   The Bureau of Land Management (BLM dept of Interior) was know to be *worse* in the sense that their rules on cattle and mining were much less careful of protecting the landscape and biome.   The National Parks were derided by both the Forest Service and the BLM for being "much too restrictive" (no "harvesting of resources"!!!!)

And yet NOW we realize how "unwise" all of that was.   But in the same breath we suggest that all of our exploitative depradations of the planet's "resources" are necessary and possibly "a really good thing"...  and I am sure that in another 20 or 50 years we will be lamenting *all* of the things that today we are promoting wholeheartedly in the name of "progress".

This is part of how I became a neo-Luddite.

Let's hope they are a bit more wise in managing the wildfires in the future than they were in the 20th century.

Before this unprecedented era of mega-blazes on the US west coast, California’s forests had a canny, ingenious way of avoiding destructive worst-case forest fire scenarios. By periodically removing the grasses, shrubs and young trees – known as the forest understory – California<https://www.theguardian.com/us-news/california> avoided fires growing to destructive intensities before the 20th century. The way this was done? Fire.

Every five to 15 years, groundfires would burn through the forest, killing off the undergrowth on a regular basis, thus removing the material that can act as tinder and kindle fires. Such groundfires were sparked by lightning or by indigenous people who used sophisticated burning practices to facilitate crop growing and hunting. Because the fires occurred frequently, the understory rarely had time to build up enough combustible material for the fires to reach the canopies of the mature trees – which is what causes the large, devastating fires we are seeing now. As a result, overstory trees might get wounded by the groundfires, but they would rarely get killed.

Due to climate change there will be more and more wildfires in California, Arizona and New Mexico in the coming years. Drones could help to detect wildfires early.
