Transition Zones
Habitat fragmentation and disruption of wildlife movements are great threats to endangered species. Habitat loss and global climate change threaten the survival of large fractions of species. The northern slopes of the San Gabriel Mountains represent a transition zone allowing species and plants to migrate up and down the slopes to adapt to climatic changes. Numerous small streams convey runoff from the mountains, and recharge declining ground water levels resulting from the population growth in the western Mojave Desert.
Sheep Creek Wash
Flash flood in Sheep Creek Wash
Along Sheep Creek Wash, the most rapid infiltration occurs in upstream reaches near the mountain front.
Our goal
Protect important natural resources, elevational transition zones, wildlife corridors, habitats, plants, animals, landscapes, streams, and view sheds along the San Gabriel mountains and in the Western Mojave Desert for future generations to enjoy.
All communities need local parks and natural areas where they can walk in nature and recover from the daily stresses in our lives. Park planning and protecting our natural resources is part of our responsibility to our children and grandchildren.
