The Palo Verde Ecological Reserve (PVER) encompasses more than 1,350 acres. The California Department of Fish and Wildlife made this property (formerly known as the Travis Ranch) available to the LCR MSCP for habitat restoration activities.

The eastern boundary of the property (more than 4 miles) is adjacent to the Colorado River, and the western boundary is adjacent to active agricultural fields. Planting of the conservation area was completed in 2013, with over 1.8 million riparian trees and shrubs planted in a phased approach over 8 years. The entire habitat will be managed and maintained for the 50-year life of the LCR MSCP. The intent of the conservation area was to create as much riparian habitat as practical. The restoration includes a mosaic of habitats that contain areas of riparian species (including mesquite) and ground covers or open areas. Ground cover is an effective method of controlling non-native species and provides another layer of vegetation for habitat. Generally, all phases at PVER are targeted for southwestern willow flycatcher, yellow-billed cuckoo, and other covered species. Reclamation and its partners will continually monitor conditions to ensure the proper habitat structure is present through the 50-year period.

Bird Monitoring

Surveys for covered birds are conducted annually. During the late spring and summer, presence surveys are conducted for riparian birds to document use of the conservation area for nesting, foraging, and migration. Riparian birds monitored include the listed southwestern willow flycatcher and yellow-billed cuckoo, and the following covered species: Arizona Bell’s vireo, Gila woodpecker, gilded flicker, yellow warbler, summer tanager and vermilion flycatcher.

Mammal Monitoring

Small mammal live trapping is conducted annually to monitor presence of Colorado River cotton rats and desert pocket mice at the conservation area. Bat presence is monitored annually from June through August with net captures and remotely recording echolocation calls using a long-term Anabat™ station.

Insect Monitoring

Surveys are conducted for MacNeill’s sootywing annually to document presence of the species in the conservation area.

Riparian Management

The final phase of PVER (Phase 8) was planted in the spring of 2013, completing the planting phases of the project. To date, approximately 1,032 acres of cottonwood-willow, honey mesquite, and upland buffer areas have been established at PVER.  Over 1.8 million trees and shrubs have been planted over the entire acreage, which will provide habitat for many species. Continued irrigation, maintenance, and on-site management for the established habitat and areas will be maintained throughout the year.
