Spent pretty much my whole day off burning through this thread, it fuckin' rules. Animorphs was probably one of my favorite series when I was a kid, and I have
very distinct memories of checking out the first two books that were on display in my school library when I was in 1st or 2nd grade. Loved those books.
Also, to go back two pages:
This does raise the amusing point of location. "I can't tell you where I live... except it's the United States, on the coast, with mountains and forest in close proximity..."
edit - did they mention it was state forest? I was never really clear on what that means, but I would assume it can't be national park if they're logging. I remember when I first drove across Australia being perplexed by the huge swathes of bushland in Western Australia which weren't marked on my roadmap as anything in particular. They weren't national parks, they weren't state forest, they were just... wilderness? Which I guess is national land by default? But I wouldn't think there's much of that going around in California.
So in the United States, there are a variety of what we call "Land Management Agencies." These are all government agencies that manage lands owned by the federal government, and include the National Park Service, Bureau of Land Management, US Forest Service, US Fish and Wildlife Service, the Army Corps of Engineers, and a few others. Each of these agencies have different purposes, and will manage lands in different ways-for instance, the National Park Service manages areas designated as National Parks, Monuments, Battlefields, Historic Sites, Seashores, Recreational Areas... stuff like that. The NPS mission is to preserve these sites for current and future generations, so generally speaking there's not going to be much in the way of logging or resource extraction (Though there are some historic exceptions-there was an active uranium mine on the rim of Grand Canyon until 1968, for instance), and large tracts of land are managed as pure "Wilderness"-a legal definition which effectively means nothing can be built there, and no vehicles are allowed.
National Forests, meanwhile, are operated by the US Forest Service, under the Department of Agriculture. Though these areas are under federal protection, these protections are less robust, and development, such as logging, can occur. But any development is going to take
years of permitting processes and (likely) legal battles to go through, so realistically the Yeerks would have a hell of a time getting permission to clear-cut any significant portion of the forest before they flat-out took over the earth anyway.
(Also, as an extremely pedantic point that stems from when I was going through Book 3 this morning, all the rangers would be Forest Rangers, not Park Rangers. They wish they had our flat hats).
