We have three main questions.
Has planting increased over time overall? What about in low and high income areas?
Are the same types of trees being planted? Do the proportions of native/evergreen/large trees differ across different incomes?
Do planted trees persist? Which ones last a long time, and which ones die out after a few years?
To answer these questions, we're using a dataset of street tree plantings provided by the Portland Parks & Recreation Department of Urban Forestry.
Our final paper can be found here.
