Why We Meet

The Puente-Chino Hills Task Force is a part of the Sierra Club working towards the preservation of the Wildlife Corridor as an island of beauty and biological significance in a sea of urbanization.

The development of the middle of the Wildlife Corridor will increase traffic, increase pollution, crowd schools, destroy wildlife habitat, and impact everyone's quality of life. 

Biological Significance of the Wildlife Corridor

  • This ecosystem is a global "Hot Spot of Diversity" - one of the world's most biologically rich and threatened regions.
  • Numerous federally listed endangered species exist in these lands. In addition, many rare species are present, including a remnant population of the rare Tecate Cypress tree that once covered most of the southwestern United States.
  • This hillside system is a "Missing Linkage" as delineated in study released in 2001 by The Nature Conservancy, the San Diego Zoological Society, State Parks, and others.
  • Much of this landscape is part of the United States Fish and Wildlife Service designated "critical habitat" for California coastal gnatcatchers.
  • Nearly 5,000 acres lie within Los Angeles County Significant Ecological Area #15 and the Department of Fish and Game's Significant Natural Area #94.
