The National Park Service is beginning a lengthy study of how best to conserve corridors of wilderness around the heavily urbanized Los Angeles Basin.
The $500,000 study will look into possibilities for how best to protect habitat for wildlife, including migrations, and recreational opportunities for millions of people living nearby.
Congressman Adam Schiff and officials of the Park Service and Angeles National Forest outlined the study Friday at a nature preserve in Eaton Canyon above suburban Pasadena.
The study area stretches from the Santa Monica Mountains National Recreation Area through mountain ranges ringing Los Angeles' San Fernando Valley to the Angeles National Forest north and east of the city.
A report will go to Congress in about four years.
