Cooling through Growth Dynamics
Regular pruning maintains the tree’s juvenile growth dynamics over the long term — and high growth dynamics also mean high cooling performance.
After pruning, a comparatively small crown volume is supported by a large and highly efficient root system. Water and nutrients are transported through newly formed, highly active vascular pathways into the young shoots. As a result, leaf mass and crown volume multiply within a short period of time.
It is precisely this young and highly active leaf mass that generates intense transpiration and therefore cooling.
CPT trees therefore cool most effectively when it matters most: during hot summer afternoons with high transpiration performance and intense water release.
At the same time, another advantage emerges:
Fast-growing CPT tree species develop their climate effect much earlier than slowly growing climate-resilient urban trees. While many of these species require decades to develop larger crowns, fast-growing CPT trees can achieve effective shading and transpiration performance within just a few years.
CPT therefore combines:
- rapid growth
- early climate impact
- high transpiration performance
- and long-term controllable crown sizes
Cooling performance therefore arises not only from crown size, but from continuously active growth, physiologically young leaf mass, and highly efficient vascular pathways.
