Big Bear Valley, CA, May 20, 2011, noon - Mother Nature provided some natural tree pruning again this year with the heavy snowfall during the winter months. As you work around your mountain home this season, Big Bear Valley Fire Agencies remind residents and property owners to create defensible space by limbing up trees, thinning out heavily treed areas on your property, and clearing overgrown vegetation. For specific steps and tips, visit www.thinisin.org. The Big Bear Valley Free Chipping Program is on demand this year valley wide. Once you have limbed up, thinned out, and trimmed back, call the toll free chipping hot line at 877-771-CHIP (2447) to coordinate FREE pick up. Chipping crews will be at the curb to chip your branches and tree limbs into mulch.
