i doubt any tree will ever die from damage ocured by a tarp line. the bsa and other lnt organizations have been setting up tarp ridgelines for cooking tarps and such for years, and i've never heard of anyone being concerned about tree damage from such activity. but, just b/c it doesn't cause damage, doesn't mean someone can't claim that it does.
isn't bear bagging still widely accepted? this is way worse than even hanging without tree straps, as the line saws into the bark of the tree as the weighted bag is raised and then lowered again in the morning.
tree straps should definately be used for the suspension, but for a tarp, might be pushing it.
