The Biden administration announced Thursday plans to expand the heavily visited San Gabriel Mountains National Monument. The president signed a proclamation that called for the addition of 105,919 acres of federal lands to the monument’s current 346,177 acres of the Angeles National Forest. “In 2021, the national forest received 4.59 million recreation-based visits, according to the U.S. Forest Service. “This intense level of use, especially on peak days, can create management challenges that include excess trash, inadequate bathroom capacity, overflow parking that impairs emergency access, and adverse impacts to fragile water ecosystems.” In 2014 President Barack Obama initially designated the monument, which now includes popular trails and destinations such as the Cobb Estate, Eaton Canyon, Sam Merrill Trail, Millard Canyon and Brown Mountain. “What a momentous day for Angelenos,” Rep. Judy Chu, D-Pasadena, said in a statement. “Thanks to the passionate advocacy for many decades of a vibrant, diverse coalition of Indigenous community leaders, community activists, and nature-lovers across Southern California, President Biden is expanding the boundaries of the existing San Gabriel Mountains National Monument and protecting more of a national treasure in our backyard.
