The Damage done by trees already on the ground can do upwards of 80 through armor. In my case I had two trees logs on the ground one was behind me the other was in front. The log I was facing came towards slowly so i jumped and even jumping it touched me. Because i was in contact with another log when I jumped it inflicted upwards of 80 killing me. That is a failing tree mechanic! Unfortunately this is not the only time that a ridiculous amount of damage was done by trees already on the ground. That is why I now consider trees the highest damage dealing creature, object, or thing in this game!
