What type of support system allows for more tree sway?

A dynamic support system is specifically designed to accommodate and allow for more movement or sway in trees. These systems enable the tree to flex and bend naturally with environmental forces such as wind, which is crucial for the tree's health and stability. By permitting this movement, dynamic support systems reduce stress on the tree and are often more effective in maintaining the tree's natural growth pattern while providing necessary support.

In contrast, static support systems, fixed support systems, and permanent support systems tend to limit movement and may not adapt well to the dynamic forces that trees face. This restriction can lead to increased stress and potential damage to the tree, as it does not allow adequate sway to absorb shocks from wind or other pressures. Instead, dynamic systems create an environment where the tree's natural resilience can be utilized, promoting overall health and stability.
