- Leaves of three-tip sagebrush are deeply cleft into three lobes.
Common Names & Scientific Names
- Wyoming Big Sagebrush: Artemisia tridentata ssp. wyomingensis
- Three-Tip Sagebrush: Artemisia tripartita
- Basin Big Sagebrush: Artemisia tridentata (subspecies not specified in all instances)
- Mountain Big Sagebrush: Artemisia tridentata (subspecies not specified in all instances)
- Low Sagebrush: Artemisia arbuscula arbuscula
Distribution and Habitat
- Sagebrush is dominant across the western United States, particularly in Wyoming, Montana, and Nevada.
- Specific locations mentioned include Park County, Wyoming and areas east of Colorado.
- Wyoming big sagebrush sites may be found at lower elevations.
- Mountain big sagebrush is often found at higher elevations that are wetter and cooler than Wyoming big sagebrush sites.
Morphological Characteristics and Growth Habits
- Three-tip sagebrush is a rounded, freely branching, evergreen shrub.
- Leaves of three-tip sagebrush are gray-green, long, and deeply cleft into three lobes.
- Wyoming big sagebrush leaves are 1-3 cm long and 0.3-1 cm broad, with wider outer tips divided into three lobes.
Ecological Role and Interactions
- Sagebrush species are a crucial component of sage-grouse habitat, serving as a food source. Palatability varies among different sagebrush types, with some being more palatable than others.
- The text mentions interactions with other plants, such as bluebunch wheatgrass, rubber rabbitbrush, and Douglas rabbitbrush, indicating their presence in similar habitats.
- Fire can impact sagebrush habitats, influencing the distribution and recovery of different species and subspecies. Long fire-return intervals are needed for Wyoming big sagebrush to dominate.
- The risk of shrubland invasion is also mentioned.
