To grow urban trees to peak ecosystem benefit, they need to be the type of tree for the region and given 1500 cubic feet of non-compacted soil volume. Analysis of the 1,791 (and counting!) trees in the Santa Fe trees inventory project shows that these can transpire up to 336,343 cubic feet per year. They mitigate 11,600 cubic feet per year of stormwater runoff. They sequester 7.925 tons of carbon and store 482.6 tons, which is valued at $82,300. These trees, which represent a mere 16% of the public park system, have an overall structural value of $3.47 million. Public park trees only represent a small fraction of the total urban forest, as most trees are growing on private property. Figures are based on I-Tree Eco algorithms for Santa Fe, NM.
Factoring energy efficiency into design helps place trees where they are cooling buildings on hot days. Trees need a minimum of 1500 cubic feet of non-compacted soil for optimal health. Accounting for growth, the tree will provide exponential value over time.
