Crystal Lake Recreation Area temporarily closes for pesticide spraying against Western pine beetles, April 9-14.
Crystal Lake Recreation Area in the San Gabriel Mountains temporarily closes April 9-14 for pesticide spraying to protect trees from Western pine beetles. Ponderosa, Jeffrey/ponderosa hybrids, and Coulter pines will be sprayed with bifenthrin, and the treatment will be applied from the base up to 45 feet. Pine beetle infestations have increased as climate changes, causing greater tree destruction.
