Current Initiatives

For fiscal year 2016 (FY16), TCA’s Environmental team is focused on four key initiatives.

  • Wildlife Fence

    SR 241 Wildlife Protective Fence

    The largest of TCA’s FY16 environmental initiatives is the extension of the Wildlife Protection Fence along State Route 241 and the beginning of an ongoing study of the benefit the fencing provides to local wildlife. These findings will help TCA and other transportation agencies design and build future projects. The 10- to 12-foot-high fence was constructed to protect mountain lions, muledeer, coyotes and bobcats living in the Santa Ana Mountains from passing cars. In addition to shielding them from the road, the new fence, which spans a distance of six-and-a-half miles, will also funnel them to existing wildlife bridges and culvert undercrossings that allow them safe passage to open spaces on either side of the road. The project was the result of a joint study with University of California, Davis into the movement and health of the area’s wildlife, including GPS tracking of mountain lions. Want to learn more?

  • Live Oak

    Live Oak Plaza

    TCA will continue to manage Live Oak Plaza, a 23.2-acre site that forms a wildlife connection to the Cleveland National Forest. Its oak woodlands, riparian and coastal sage scrub provide habitat for the California gnatcatcher and Riverside fairy shrimp.

  • Strawberry Farms

    Strawberry Farms Mitigation Site

    TCA will continue to restore 15 acres of coastal sage and cactus scrub habitat and native perennial grassland at Strawberry Farms, located in Irvine and overlooking the Strawberry Farms Golf Course. Part of the larger Central/Coastal Natural Community Conservation Plan area, the open space is home to several species such as the California gnatcatcher and the coastal cactus wren.

  • Upper Chiquita Canyon

    Upper Chiquita Canyon Conservation Area Management

    TCA oversees the ongoing management of this 1,158-acres of open space under existing agreements with U.S. Fish & Wildlife Service and the California Dept. of Fish & Wildlife. Among TCA’s responsibilities are preserving, managing and restoring this preserved habitat, including weed control and scientific testing of different habitat management techniques. Before TCA purchased this property near Coto de Caza, the former grazing pasture was zoned for residential and golf course development. Now permanently protected as open space, the restored habitat supports important populations of the California gnatcatcher and coastal cactus wren. Several families of deer are usually spotted running throughout this site on any day.
