Then there's stuff like the "SAS Survival Handbook" by John Wiseman, and similar, which would be very insightful as regards food resources. Also has a load of stuff you should know if you're gonna go out in the woods much.
Other non-BF centric reading, some Fossey and Goodall, and stick a pile of National Geographics by the potty, lots of tangential anthropology, primate, archeology and palaentology stuff you can glean out of those.
Then for more "how the hell do they do it" type stuff you can look out stuff about escape and evasion techniques, elite forces operating procedure and tactics, some older stuff such as the WWII history of the SAS, LRDG and "PPA" is educational also, bearing in mind that hiding in the woods is childs play compared to hiding in the open desert behind the lines of Axis powers who had air superiority at the beginning of the campaign (Screwing that up was a big part of the mission) all without getting zapped or captured. Then top off with some sniper training material, both for insight into how not to be seen, but also how to see.
Then of course there's tracking manuals, general nature and geology books, (hint hydrology and trees and relationships could let you read the terrain better)
Then of course a recent copy of Skeptical Enquirer should be with you at all times while in the field, hermetically sealed in a ziploc bag... just in case you find yourself in need of dry tinder or TP.
