Arizona Wildlife Conservation Strategy

Quigley-Achee COA

This COA has been identified as an Important Bird Area (IBA) because it has nearly 20 acres of wetland habitats that are critical for wildlife in this otherwise arid agricultural landscape. The area is home to several secretive marshbird species, including the federally-endangered Ridgway’s (Yuma) rail. Invasive salt cedar and arroweed continue to threaten these habitats and consistent management is required to keep these species in check. Abundance of these invasive species is also increasing fire risk at the site.

Conservation Goals

  • Invasive plant species are removed and restored with native species, including cottonwood and willow.
  • Adequate water levels in wetland areas are maintained to provide quality habitats for nesting birds as well as migratory stopover habitats.


Primary Threats

1. Agriculture

1.3: Livestock farming and ranching

3. Climate Change and Severe Weather

3.1: Habitat shifting and alteration

8. Invasive and Other Problematic Species

8.1: Invasive non-native species

9. Natural System Modifications

9.1: Fire and fire suppression

Potential Conservation Actions

2. Land and Water Management

2.1: Site/area management
  • Improve groundwater management to maintain water levels in wetlands habitats.
2.2: Invasive/problematic species control
  • Remove invasive salt cedar and other invasive plant species to improve habitat quality and reduce risk of devastating wildfire.
