We maintain our urban forest with mapping from ArcGIS, and this includes our map of the Ash trees on campus grounds. This is our working map, tracking our Ash trees by maintenance requirements, priorities, and health. If the map below is not working, or a larger view is desired, the app is also found here.

We have mapped (https://arcg.is/vez5a) over 700 ash trees on campus grounds and outside lands, based both on the campus tree map and outstanding work from 2 student interns, thanks to Marc Lapin. Ash trees were mapped only if they were near a ‘target’. This includes not only the obvious ones such as transmission lines, roads, buildings, sidewalks, but also less obvious ones such as sports fields, trails, or abutting neighborhood lands, like backyards.

Trees were mapped into 4 locations (n=721)

1. Utility (55 trees)-near a transmission line, either a powerline along a road or backyard, or a power drop to a structure.
2. Right of Way (ROW) (43 trees)-this is an Ash next to either a public or private road.
3. Campus (333 trees) -any tree not like the above on campus land.
4. Private (290 trees)-trees on ‘outside house’ lands, or other lands owned by Middlebury surrounding the town.

Trees are also prioritized for removal, on a scale of 1-5.

1. Immediate Removal (23 trees)-based on size, health, or location, Utility tree
2. Major Target (133 trees)-major target nearby, or ROW
3. Unsightly location (90 trees)- major trees in obvious locations, or on campus grounds
4. Lower Priority (172 trees) – probably need to do these at some point
5. Lowest Priority (42 trees)- Could leave?
6. Trees marked as 0 on map (260) – trees not on campus, needs further discussion (TAM trail, legion fields, etc.)
