This short video shows you the proper technique to use when biking down wet slopes through bushes:

I was coming down a not-very-difficult rock and a I hit the soft, wet edge of the trail and, needless to say, just kept going. Just a few small cuts are the result. In my defense, I'm recovering from a strep throat and, more pertinently I was preoccupied with other thoughts. To make it even worse my chain gave me problems a couple times before then and later got stuck completely meaning I was only able to bike out of there on the downhill sections. I also did a very slow endo after the visit to the bushes. Things aren't usually this bad, but, like I said I was preoccupied with other things.
