I just finished mining over 120 more planning documents for information about trees cut for developments in Surrey. Now I’ve gone through all the planning documents Surrey has online since 2012, except for July/Sept 2014.
These graphs are estimates, since planning documents don’t always list the numbers of trees they plan on cutting or planting, and planning documents aren’t tree cutting permits. I did get a list of numbers of permits given, but the city employee who had gathered that information didn’t want to make it public. I can tell you that it reflected the numbers I’ve gotten from planning documents.
In South Surrey, where I live, these numbers are often forests being turned into residential developments. I can’t give exact numbers on that because the COSMOS mapping people said they’d have real trouble trying to export data in comparable formats from the two relevant layers (the ecological survey and planning documents).
