This lichen favors mature and old growth, wet conifer and hardwood forests with clean air. A. sarmentosa is sensitive to air pollution and used for air quality monitoring. Areas required by A. sarmentosa are found in northern and southern temperate zones and receive high rainfall. This lichen is commonly found in transitional areas between valley and mountainous forests, but usually avoiding the immediate coast.
