A Hollow tree is a lumber tree requiring level 45 Woodcutting to cut. The tree provides Bark when cut and 82.5 Woodcutting experience per piece of bark collected from the tree. Hollow trees only grow in select areas of Morytania. Hollow trees are primarily cut in order to gather bark to make splitbark armour. Hollow trees are cut very infrequently, due to the restricted and remote location and limited use.
Hollow trees are exclusively located in Morytania. Hollow trees are shown on the World Map and Minimap as a bushy tree . This image is shared with several other trees, so a bushy tree on the map does not directly mean it is a Hollow tree. The quickest way to reach Hollow trees is to use fairy ring code ALQ. The safest location for harvesting them, however, is South of Port Phasmatys.
Hollow trees have a 1 in 8 chance of depleting when receiving a piece of bark, and a respawn time of 26 seconds. A roll to receive bark is done every 4 game ticks when chopping. The chance to successfully chop is affected by the axe used and Woodcutting level, better axes and a higher woodcutting level increases the likelihood of successfully receiving bark.
