Our Completed Habitat Management Projects


Carlsbad Hydrologic Unit Riparian Habitat Restoration and Maintenance

For more than 10 years, ACS Habitat Management has been the primary contractor responsible for the removal and control of invasive plant species and native revegetation of selected areas within the Carlsbad Hydrologic Unit. This management unit is comprised of seven watershed districts in northern San Diego County where we have:

  • Controlled invasive species throughout roughly 280 acres of riparian watershed areas encompassing Agua Hedionda Creek, Buena Creek, Buena Vista Creek, Encinas Creek, Escondido Creek, Loma Alta Creek, and San Marcos Creek
  • Successfully controlled Arundo, tamarisk, pampas grass, palms, and various other highly invasive riparian species
  • Coordinated with landowners to gain right of entry while being active in public outreach to inform landowners of non-native plants’ negative impact on the watershed ecosystem and the benefits of the invasive species program

We have been working on the Channel Islands of California for more than a decade. Part of that is our effort toward preserving San Nicolas Island’s unique and delicate habitat.

Our crew members and managers have intimate knowledge of the island’s unique geography and sensitive habitats as well as the non-native invasive plant species that threaten them. The tasks we have successfully performed on San Nicolas Island include:

  • More than 10 years of non-native invasive species control, including the near eradication of the once prevalent fennel (Foeniculum vulgare) and diligent control efforts focused on the Saharan mustard (Brassica tournefortii)
  • Being the first to respond to the highly invasive and recently discovered carnation spurge (Euphorbia terracina)
  • Managing a native plant nursery refurbishment project on the island that allowed the propagation of locally collected seeds, which can be used for restoration efforts
  • Managing the installation of more than 1,300 native plants that propagated from locally collected seeds at the Thousand Springs restoration site

Marine Corps Base Camp Pendleton Artichoke and Yellow Starthistle Control

We have been an integral part of Camp Pendleton’s weed control programs for more than 15 years. An example of this is the Artichoke and Yellow Starthistle Control Program.

Before, these thistle species could be found in concentrated numbers throughout the 100,000-acre installation. Today, only sparse populations remain and the control of these plants is becoming more targeted.

Our Contributions to the Project

  • We were the first firm to begin using GPS technology to map individually treated weed populations on the base.
  • Our team helped develop the current GIS geodatabase design that was used for tracking and managing the control program.
  • Comprehensive annual reports and GIS deliverables that we produced helped base personnel make land management decisions.
