Tree Swallow on Nest Box

Rockfield Quarry earns Conservation Certification from the Wildlife Habitat Council through regional alignments

Rockfield Quarry maintains 20 nest boxes for resident and migratory cavity-nesting songbirds that fledge over 100 birds annually.

The San Joaquin River constitutes a unique and important environmental, cultural, agricultural, recreational and wildlife resource in the rapidly urbanizing Fresno-Madera region of central California. The 22-mile reach of the river between Friant Dam and Highway 99 consists of approximately 6,000 acres of San Joaquin River bottomlands.  This particular reach of the San Joaquin River is of statewide significance. CEMEX’s Rockfield Quarry is located adjacent to the San Joaquin River. As part of the regional effort to restore and enhance streamside forest habitat, CEMEX has installed and continues to monitor and maintain 20 nest boxes for cavity-nesting songbirds like ash-throated flycatchers, tree swallows, house wrens and western bluebirds.

The nest boxes are located along the riparian corridor of the San Joaquin River, just south of Lost Lake Park Audubon Important Bird Area and fledge over 100 birds annually. Installing nest boxes provides migratory birds with nesting sites to raise young in their breeding habitat and roosting sites in their overwintering habitat. This conservation project aligns with the important conservation needs of the area, resulting in more meaningful and greater impact.

The Rockfield Quarry not only participates in projects that align in conservation, but also in building a better future for the community.  The Rockfield Quarry collaborated with the Art of Life Cancer Foundation and the City of Fresno on the development of the Art of Life Healing Garden at Woodward Park in Fresno, Calif., which provides a space for the community to go for sanctuary, celebration and healing.
