Forest Walking

Almost two-thirds is all about plants and animals in the forest and how to appreciate them, (I'll admit I skipped the sections on making it fun for kids, not my area) then the switch seems to be to practical aspects of walking in a forest - when weather is safe vs dangerous, whether you should rely on foods to be found there (broadly no), how to start a fire (if it's not banned), a couple tips if you happen to find yourself off trail (i.e. lost), what to wear. This is followed by a note on spotting old growth and how to preserve it. 
As the In Closing section says it: “This book is not a reference book. It's an appetizer. “

If you're interested in wilderness survival or foraging  or off trail hiking I think there's probably more comprehensive guides out there. If you'd like to dwell in the land of interesting nature facts, the first two-thirds-ish are a fun read.
