ISA certified municipal arborists had me and other guys climb with spurs to remove hangers left after a storm that were above paths. Meanwhile, the big snags, some of which were over 80' tall, and less than 20' from the paths or playgrounds, were left alone. Wildlife trees, I guess.
In the bush, logging companies are fined thousands of dollars for working close to snags, you have to fall them first, by law. I guess the park users are more on the ball than the loggers, looking out for falling stuff that can kill them and all that.........
