I would call an increase from 27% to 36% a 33% increase in tree coverage compared to the average city. Not only that, it's the top tree covered city on the source article for that wiki entry: http://www.deeproot.com/blog/blog-entries/tree-cover-how-does-your-city-measure-up http://www.deeproot.com/blog/blog-entries/tree-cover-how-doe... Also based on that list, the 27% average seems to be artificially high by giving equal weight to cities of all size given how the largest US cities are all well below 20%.
