In selecting a cedar tree to fell, the Stó:lō have to consider a number of things. Is the tree straight and free from knots? Is the tree free of rot in the interior sections? An initial assessment for rot is to hit the tree to listen for a hollowed trunk. This initial test is followed by making a small hole into the tree that extends to the centre of the tree. This test hole enables the tree-faller to assess the state of the wood on the inside of the tree.
