Is Seattle doing enough to save its trees?:
Tree advocates have been complaining for years that the city needs to do a better job of conserving its canopy of trees, which has declined over the decades because of development.
The city has estimated that the amount of land with an overhead tree canopy decreased from 40 percent in 1972 to 18 percent in 2006, though it now says the coverage is nearly 23 percent.
Tree policy issues are complicated, city hall sources say, pitting desires for tree preservation against conflicting pushes for more densely-packed developments.
