Tree pits are used in hardscapes to reduce compaction and extend the life of urban street trees. We're piloting new tree grates & guards to protect these trees. This new design makes it easier for staff to care for these trees. #UrbanForest #StreetTrees 
This pilot study removed pre-cast concrete pit cover panels from 18 trees on Spadina Ave. Almost every tree that was 20 cm dbh or greater exhibited damage to the trunk or the panels. The new pit cover design addresses these issues. #UrbanForest #StreetTrees
Concrete covers hard to maintain, can leave grade change between sidewalk & tree pit. New grates have larger tree openings to accommodate long-term tree growth; adjustable legs to maintain level grade w/sidewalks. Developed w/ @TO_Transport & CityPlanTO #UrbanForest #StreetTrees
Spadina pilot: Remote soil moisture monitoring tells Urban Forestry staff exactly when newly planted trees need to be watered to maintain optimal soil moisture until trees are established. Developed through a research partnership with @BeWhereInc #UrbanForest #StreetTrees 
Spadina pilot: Compaction and salt are two things Toronto #StreetTrees must endure. Engineered soil is designed to optimize the availability of water and oxygen, as well as improve drainage to remove salts and other toxins. Developed in partnership with @TRCA_HQ #UrbanForest
Spadina pilot: Permavoid cell is installed at the bottom of a tree pit. This system acts as a reservoir to collect and re-use water, extending moisture availability to newly planted trees to aid in establishment. Developed in partnership w/
