Trees are an important part of our environment, in urban areas no less than in the wild. Clean air, clean water, carbon sequestration, shade, temperature control, increased property value, and wildlife habitat are a few of their benefits. Many urban areas - like San Diego - have policies preserving, protecting and encouraging the planting and growth of trees. Everyone loves trees, right?

So, why are trees in trouble? Why are urban forests shrinking instead of growing? Why would majestic 50-year-old trees lining a public sidewalk be leveled to the ground? Why are new street center dividers mostly concrete and asphalt instead of tree planters? Why not fill those empty spaces with green?

Well, not everyone loves every tree. That spectacular tree in your neighbor's yard might be a maintenance nuisance in yours. A tree might be legally protected, but the guy with a chain saw might not know that. The city might love trees, but not love the expense of taking care of them.

Advocates are needed to speak for the trees, especially in urban areas. TreeWatch is a neighborhood-based, community-science volunteer program to involve residents in identifying and protecting their local city trees and contributing to implementing the City’s Climate Action Plan.
