Urban Tree Canopy and Wildlife Welfare

Urban trees provide critical welfare resources for birds, bats, and invertebrates, and the ongoing removal of urban trees for development threatens these welfare networks.

Key Facts

Welfare Considerations

Urban trees are welfare infrastructure: each mature tree is a habitat for hundreds of species, providing food, shelter, and nesting sites that would otherwise require acres of rural habitat. The removal of a 100-year-old tree for a development project eliminates welfare-supporting resources accumulated over a century. Species that depend on old growth features — woodpecker cavities, bat roosts, lichen communities — cannot simply move to younger trees. The welfare argument for urban tree protection is both direct (for tree-dependent species) and indirect (for the cooling and air quality services trees provide all urban wildlife).
