We’re doing what we can to protect our trees and to be forward-thinking when it comes to ways to save them. Our county-wide Heritage Tree Preservation Program was initiated to catalog existing mature trees and to establish requirements for maintaining tree diversity and density in all County Parks.
Faced with extreme drought conditions, many trees shown signs of drought-related stress. Stress may not kill a tree directly, but it can weaken it – making it susceptible to more serious secondary pathogens like pest infestations and fungus. A healthy tree can fight an infection, but a thirsty one may not and it’s because of this, that tens of thousands of trees have died throughout San Diego County.
In an effort to preserve trees, the Department of Parks and Recreation (DPR) developed a Heritage Tree Preservation Program. This program analyzes the health of trees on County land, and establishes requirements for maintaining diversity and density to safeguard their existence and the growth of new natural landmarks, for generations to come.
Key components of the program are to:
When new trees are planted, we follow a couple of general rules:
Mature trees offer shade and contribute to biodiversity. They also serve as important climate buffers to moderate temperature and moisture. DPR is building sustainable landscapes within parks to support local ecosystems, enhance park experiences, and reduce our carbon footprint.
