Least Bell’s Vireo Status in Prado Basin From 18 territories in 1986 to 665 in 2018 due to OCWD’s successful Wildlife Management Program Including SAWA territory numbers, we have nearly 2,000 territories, which is the largest number of territories in the Santa Ana Watershed since listed as endangered Least Bell’s Vireo Nest Monitoring Vireo Nest Video Habitat Restoration • Removal of Non-Natives • Natural Recruitment • Planting Natives We restore habitat by first removing non-native plant species and allowing either natural recruitment to take place or actively planting native riparian species Removal of Non-natives The focus for removal is Arundo because of the many problems it causes but there are many other problematic invasive plants, Tamarisk, Palms, and Castor Bean, e.g. Native Plants Planted by: •Natural Succession •Volunteers •Contractors •Staff Our Natural Resources Program is responsible for planting 2 acres of native habitat in Prado Basin And 2 acres in OC facilities per year OC Recharge Facilities: Lower Santa Ana River Recharge facilities, river & off-river channel = 1,000 wetted acres OCWD biologists work closely with the Operations Department to protect wildlife Burris Island Burris Drone Video Burris Basin & Island • Burris Basin ~ 120 acre • Water storage and percolation basin • Downstream and adjacent to Santa Ana River • City of Anaheim near Anaheim Stadium • 14 miles from ocean • In 2008, OCWD confirmed nesting of CA Least Terns, a federally and state listed endangered species Aerial photograph of Burris and surrounding recharge basins near the Santa Ana River Burris Wildlife Burris Wildlife Video Bird Nesting Box Program Accommodating wildlife, strong environmental stewardship helps in the regulatory arena; without nest cavities, many of these charismatic and useful species would be rare.

  • Studying Orange County Plants by Bob Allen California Native Plant Society, Orange County Chapter
    Studying Orange County Plants By Bob Allen California Native Plant Society, Orange County Chapter http://www.occnps.org/ So, you want to learn about wild plants in Orange County? This little guide should get you started. Geography The geographic features of our area extend a bit beyond our geopolitical borders. Thus we share some natural features with our neighboring counties: Los Angeles, San Bernardino, Riverside, and San Diego. The following are our major geographic features. • Los Angeles Basin. A low-lying expanse that encompasses the coastal plain of Los Angeles County southeast into Orange County. The portion of it that lies south of the Santa Ana River, between the Santa Ana Mountains and San Joaquin Hills, is technically called the Tustin Plain. • San Joaquin Hills. A range of seaside hills that parallels the coast, from Newport Beach to Dana Point. • Lomas de Santiago. A range of inland hills that parallels the coast, inland of the Tustin Plain. • Chino Hills. A range of inland hills in the northern portion of our area. Their northwestern region is called the Puente Hills; the two features are sometimes together called the Puente-Chino Hills. • Santa Ana Mountains. A range of peninsular mountains, it extends from the Santa Ana River southeast into western Riverside and San Diego Counties. A steep-sided range of many peaks and deep canyons that support an abundance of wild plants and animals. • Temescal Valley. An inland valley, south of the Santa Ana River, from Corona & the southeast. It lies between the Santa Ana Mountains and the Gavilan Hills. It drains northeast into the Santa Ana River.

Adam Scott Miller A Watershed Event For a Watershed Community: The Development of Flood Control for the Santa Ana River Basin BY ADAM SCOTT MILLER ABSTRACT: Southern California receives the vast majority of its yearly rainfall in the relatively short time period between the months of December and March. Occasionally, this intense rainfall creates floods that have historically threatened and devastated the communities of this region. The twentieth century proved challenging for local flood control agencies. California experienced tremendous population growth, resulting in migrants settling on the existing floodplains. Unaware of the periodic, hidden menace, newcomers were ruined when rivers and their tributaries flooded. It became clear that a significant change in flood control methods was required.
