I started a hazard analysis for a developer today but wasn't able to make much headway. All the corners and monuments had been pulled, watershed boundary marker, etc. Out of about 200 trees only a handful didn't have crap like this painted on them.
That's too bad. Hard to get rid of stuff like that. Someone did the same thing in Montgomery woods, on the big redwoods, but the bark is so thick on those trees that scraping the outer layer off made the trees look fine afterwards.
That thin bark is another thing. A little sand paper, maybe?
