I am visiting your town and read the article on hammocks with great interest (“What does Cal Poly’s Hammock Club do? Hang around, mostly,” June 17) — especially the part about hanging them from Big Sur’s oaks and redwoods.

My city is considering a ban on hanging hammocks from trees in city parks.
The city’s arborist has said the hammocks are damaging the trees. He said that when hammocks and the increasingly popular slacklines, which are similar to tightropes, repeatedly are tied to tree trunks, they weaken and wear away the bark, which renders the trees susceptible to insect infestation and disease. And when hammocks are tied to large tree limbs, such as the horizontal branches of live oaks, they can weaken and crack.
