Trees are important to cities. I'd like to discuss their role. At least these roles

1) Street furniture & place making
- a source of shade and comfort
- Sound deadening (noise pollution cure)
- visual screen

2) As climate partner
- stormwater management, air cleaning
- heat management
- carbon sequestration

3) Recreation asset
- Forested parks
- Rope Course?

4) Threats
- projects
- pests (gypsy moths released in Medford MA :-(
-- 17yr locusts (threat to small trees, rely on undisturbed forests)
-- asian longhorn
-- emerald ash borer
-- Chestnut blight
-- Dutch elm
-- Winter moth
- hostile people (cut a tree to steal a bike)

--- and things like ---

Tree age and size (the big issue on Melnea Cass)
- adding new trees
- getting them to maturity
- protecting them at maturity

Species selection & mix

Tree City USA
- does your town have a Forestry Plan?
- a Tree Warden?
- a prune, remove, plan, plant, grow plan?

I was inspired by this old post in the MGH thread in which we see how important Elms were in the 1800s and 1900s We may also cover how important Chestnuts were in the 1700s and 1800s

Also of interest: the black "anti climbing caterpillar" bands, which I think were an anti-gypsy moth thing?
I assume these are some sort of tarred "tanglefoot" traps on the trees in what would be a spring "pre leaf" photo:

For any pest where they mature in the canopy, but drop and overwinter in the ground, "climbing back up" in the spring was a big deal.

Which is also why Winter Moths caught us off guard, laying their "inchworm" eggs directly on leaf buds in the fall (and overwitntering) up there.

The politics of urban trees are major. See the discussion in the Melnea Cass thread with accusations of "environmental racism" by some Roxbury groups over the planned removal of mature trees along the Blvd.
