NATURE'S LIVING SYSTEMS
The living systems of nature ... including human beings ... are extremely complex and quite amazing. Despite the amazing growth in knowledge during the last century very little is known about the deep intricacies of these natural living systems. What is now known is that they are immensely important for sustaining the enviro-socio-economic system that is key to quality of life and standard of living.

Davey Tree i-Tree software

|
Davey Tree developed the i-Tree software suite in partnership with several other organizations to better quantify and understand trees as a form of natural capital. i-Tree provides urban and community forestry analysis and benefit assessment tools, enabling the valuation of a tree’s impact on air and water quality, energy use, human health and more. This in turn enables Davey Tree’s arborists to educate clients on the value of their natural capital. #12711
