Never Me took me to an evil tree today, which seems to be a recent addition to woodcutting.
People swarm around a large, violent tree, chopping away roots to get at it. They can also receive evil tree kindling, which when used on the tree gives 1k firemaking xp.
Once the tree is dead, everyone gets given a set of rewards. They get items (I received around 1kgp, 1 willow tree seed, and 12 yew logs), bonus banking (for the next 20 mins, if I have a full inventory, any logs will be automatically sent to my bank), and an increased chance of receiving birds nests from trees.
Seems fairly rewarding, and a good way to break up a dull skill.
