base.
5. The girdling roots are of 0.25m, 0.2m and 0.05m in diameter respectively. The
cutting of these girdling roots may cause the tree to uproot or it may introduce decay
into the root system and result in the tree death or uprooting in future.
6. Due to the close proximity of the tree to the building, it is recommended that the
tree be removed.
