Habitat Restoration

RESTORATION AND FIRE REHABILITATION

Camp Pendelton & Marine Corps Air Station Miramar, CA
US Naval Facilities Engineering Command Southwest (NAVFAC SW)

As part of an Indefinite Delivery Indefinite Quantity (ID/IQ) contract at Marine Corps Base Camp Pendleton and Marine Corps Air Station Miramar, Harris Environmental conducts numerous projects to protect and restore natural resources. Fire rehabilitation consists of Best Management Practices (BMPs; wattles, jute-netting, silt fencing, etc.) combined with soil erosion control (e.g., re-contouring, rolling dips, waterbars) and revegetation (transplanting nursery stock, re-seeding). Other projects include removal and eradication of non-native and invasive plant species via both mechanical and chemical methods. Harris Environmental’s support of the Bases’ habitat restoration and fire management plans is an example of how we assist the military in responsibly protecting and conserving their largely undeveloped natural resources

NATURAL RESOURCE MANAGEMENT AND RESTORATION

Yakima Training Center, WA
US Army Corps of Engineers, Seattle District

Harris Environmental conducted emergency soil erosion control and restoration at the Yakima Training Center (YTC), in Yakima, Washington. Thousands of acres of natural sagebrush-steppe were destroyed in a wildfire resulting from military activities, which include maneuver and live fire training. We successfully completed installation of over 13,000 lineal feet of wattles and over 300 rock structures to slow water velocity and increase soil deposition. Subsequently, we seeded all areas with native grass seed mixes using both aerial (i.e., helicopter) and broadcast (i.e., on foot) methods. The next phase of the project will consist of transplanting thousands of sagebrush seedlings onto the site as well as aerial seeding with native sagebrush seeds. Harris Environmetnal worked closely with YTC staff to support their military mission while restoring natural resources and habitat on range.

WATERSHED ENHANCEMENT

Guadalupe Canyon, AZ
US Fish and Wildlife Service

Harris Environmental managed a stream restoration project in Guadalupe Canyon, a remote, intermittent stream in southeastern, Arizona, and southwestern, New Mexico. Recent fires, past human disturbance (e.g., levees, road crossing), and the canyon slope had increased impacts during runoff events resulting in large channel incisions. Infrequent floodplain inundation also had reduced natural recruitment of riparian vegetation. We designed and installed treatments which included boulder weirs, log structures, and channel re-alignment to increase both sediment deposition and water retention. Treatments lifted the channel bed within incised reaches allowing runoff to rewet the floodplain and promote native vegetation growth. Headcuts and road-crossings also were stabilized using earthworks to prevent further erosion. All treatment sites as well as staging areas were re-seeded and raked with native grasses and debris and rocks were distributed to increase roughness and promote water retention. The project was a collaborative effort between the private landowner whose property contained Guadalupe Canyon, the U.S. Bureau of Land Management, and the U.S. Fish and Wildlife Service. Harris Environmental worked with the private landowner and two federal agencies to complete the project, and were sensitive to the private landowners needs.
