Louisville Mayor Jerry Abramson says trees are vital for any size community.“They filter the air that we breathe, removing some of the dust, even some of the harmful particles, they moderate our climate, conserve water, provide vital habitats for wildlife, as well as the beauty of the trees that you see that have been with us for many years," says Abramson.Governor Steve Beshear declared April 15th to be Arbor Day in Kentucky, though National Arbor Day is April 30th.
