What are some common dangers to avoid in the california woodland wilderness?



I know the question is very broad. Just give me the gist of it.



Also is there a book that covers all of this? It would be very helpful to people who want to get into camping/backpacking.What are some common dangers to avoid in the california woodland wilderness?

Depends on where in California. It's a huge state.



Mountain lions %26amp; wild boars have been known to traverse the entire length of the state. Bears are found far north. Coyotes %26amp; rattle snakes are found in the lower part of northern cali %26amp; on down to socal. Black widow spiders are common nearly all over the state. Poison ivy/oak is pretty common but not everyone is allergic to it.



Plenty of books cover it, just google "hiking camping california book."What are some common dangers to avoid in the california woodland wilderness?
