The Cambridge Tree Trust is active in promoting the planting, and protection of trees and the beautification of the entrances to the Town.
The Waipa District Council supports the policy of a protected tree list to preserve, protect and enhance the character and visual quality of Cambridge.

In 2002, an Arboriculture student, John Reid, identified 52 notable trees in and around Cambridge. The Waipa District Council has its own list, which includes most of John's, but adds those considered notable by its own arborists since 2002, and extends the area under consideration. The Tree Trust is checking both works to update them. We already know that some trees have been removed through death, disease or bad siting.
The soft, sandy pumice soil around Lake Te Ko Utu has proven unable to hold big trees. Several have fallen in recent winters. In 2013, the Waipa District Council started implementing a plan to remove them and replace them with more suitable species. One such collapse killed a dog and missed its owner by the length of the leash.
