Three tree-related projects. First is a relatively simple (but data-intensive) rethinking of tree distributions. Instead of the usual species-level blob maps, I've made a series of maps showing the actual distribution of major tree types, plus some interesting higher-level patterns.
I've then used this same data as a starting point for a new kind of bioregionalist mapping: instead of a few discrete forest regions, I'm defining "arborregions" based on the similarity between a specific place and its wider surroundings. If bioregions are really meant as an alternative to the arbitrary lines of political jurisdictions, they should challenge not just the specific boundaries, but the hardness of those boundaries as well.
Finally, I've also taken a close look at every street tree in New Haven. After the ravages of Dutch elm disease, it turns out that Elm City doesn't actually have that many elms. Instead the city is a weave of a half dozen major tree types, with dozens of others scattered throughout.
And a quick bonus map, too: the apizza region of central Connecticut!
