Sagebrush-steppe

Grass grows above sagebrush
Sagebrush-steppe occurs in the northern range in Yellowstone.

NPS

 

This vegetation type occurs in the northern range, Hayden and Pelican valleys, and Gardner’s Hole. Mountain big sagebrush (Artemisia tridentata var. vaseyana) dominates, along with several other kinds of sagebrush. Several grass species, such as Idaho fescue (Festuca idahoensis), also dominate sagebrush-steppe. Other species of the sagebrush steppe include mountain brome, needlegrasses, yampah, sticky geranium, and several species of upland sedges. The northern range can be spectacular with wildflowers in late June and early July.

In 2015, a long-term sagebrush steppe monitoring program was initiated to track the changes in plant cover and species composition over many years with an emphasis on invasive species. Data loggers will be used to assist staff with correlating any changes in the vegetation with climate change.
