This application was designed to help prioritize tree planting initatives in Philadelphia. The web application has 3 distinct features:
- This application allows you to view the current state of the tree canopy in Philadelphia! Users can view 10 distinct tree canopy statistics by
clicking on our interactive dropdown menus. Users can view these statistics in either neighborhood or grid cell (150m x 150m) form.
This feature allows the user to understand the current state of the tree canopy in a given area. Click on a neighborhood or grid cell to view all statistics for that location!
- This application allows users to view where construction permits are located! By overlaying completed construction permits with our tree canopy statistics/ tree canopy loss risk predictions,
users will notice that construction is very much related to tree canopy loss! Users can toggle the statistics or predictions on and off to view exactly where construction has occurred. Tree planters should
prioritize streets with high construction rates located in high-risk tree canopy loss regions. Users can either view construction permits from 2008-2018 or 2019- April 2021. Note: The more construction permit
categories selected, the slower the web application will be due to the large size of the construction data.
- Most importantly, this application allows users to view areas that are at high risk for substantial tree canopy loss! Each grid cell is assigned a "probability score",
which is the probability that the given grid cell will experience substantial tree canopy loss in the future. Substantial tree canopy loss is defined as a grid cell losing 25% of their tree canopy loss over a ten year period.
Click on the grid cell to view the probability score of a location! The results are based on a model predicting where tree loss will most likely occur based on attributes associated with regions with significant tree loss.
Users can view the substantial tree canopy loss risk in differing construction scenarios. You will notice through our interactive bar graph that as construction permits increase,
the risk of tree canopy also generally increases.
Please view our report for more information regarding the model.
