Populations show a jump of more than a third in some areas. The National Audubon Society created the Conservation Ranching Initiative (ACR) in order to support ranchers while protecting and renewing grassland habitats and increasing populations of grassland birds. Audubon range ecologists partner with ranchers to develop habitat management plans customized to make their land more bird-friendly through practices including rotational grazing and minimizing the use of chemicals.
Audubon’s science team has developed a Bird-Friendliness Index to quantify ACR’s impact on vulnerable grassland and aridland birds. It measures the abundance, diversity, and resilience of the bird community on ACR-certified ranchland, and compares them to conventionally managed lands.
