Results and AccomplishmentsSAWA is a non-profit entity and has obtained grants and mitigation money to manage the natural resources of the Santa Ana River. A noxious weed giant reed or Arundo had taken over more than half of the native riparian habitat on the river, perhaps 10,000 acres. SAWA has removed 3,000 of those acres so far, is maintaining those lands weed-free, and looking for the next grant to continue the relentless marsh to the Pacific Ocean. The entire upper watershed of the river has been cleaned and is being monitored by a team of 11 biologists and seasonal aids. Endangered species are monitored and managed in particular to avoid potential impacts of the weed-control activities. The least Bell's vireo is one such endangered bird that has been managed in this watershed since the early 1980s. As of 2004 the Santa Ana River population surpased that on Camp Pendleton to become the largest in existence because of our management efforts.
