The decision followed public opposition, including a lawsuit announced by a community member and concerns raised by parents, residents, arborists, and soil scientists.

Blue ribbons tied around trees in Honolulu mark nesting sites for the manu o kū, a species of white tern adapting to urban areas. The ribbons alert arborists and tree crews to active nests to prevent accidental harm.
