Two presentations on energy efficient living, bike rides and a Coastal Cleanup Day define the sustainable weekend.

Random read. Created and maintained by the Friends of Gardena Willows Wetland Preserve and Constance M. Vadheim, an adjunct Professor of Biology at CSU Dominguez Hills, Mother Nature's Backyard is a blog about water-wise and life-friendly gardening in Southern California. The latest entry reads like a love letter to the often unseen change of seasons in the region: how a drought-tolerant vegetation transforms as the months go by, how its colors move from silvers and purples to yellows and browns. Serving as a perfect introduction to the website, the post reminds us that the driest time of the year bears beauty. "Overall," it says about water-wise backyards during the months of August, September and October, "the garden is a symphony of browns; a restful blend of colors that is subtle and soothing."
