Focus on ADDING trees

I live in a neighbourhood of single-family houses. Every time I go on a walk around here, it's depressing to see large lawns that mostly have nothing but grass. Often these lawns are as big as the houses themselves! So these lawns are not providing housing for people or habitat for wildlife. What a waste! Since housing is more "controversial", more trees could be planted on these lawns. This could be a legal stipulation for a minimum number of native trees per area of a lot that is not used for housing. If the City can have stipulations for setbacks and density (which hinder housing supply), surely they can mandate tree planting. Perhaps the City could spin this as "stimulating property values" to placate homeowners.

(Too much of the focus so far is on protecting trees from removal. This will necessarily conflict with evolving needs and land uses in the city. How about increasing focus on tree provisioning as part of the strategy?)
