Facts about Bison Grazing Impact
- 06
Periodic bison grazing removes accumulated dead plant material, reducing thatch buildup and allowing sunlight to reach soil and stimulate new grass growth.
- 05
Grazing by bison keeps grasses cropped short enough to alter soil temperature and moisture, directly influencing the microhabitats available to ground-nesting birds.
- 04
Heavy bison grazing suppresses dominant grass species, allowing forbs and less competitive plants to establish and broadening overall prairie biodiversity.
- 03
The selective grazing pressure of bison promotes nitrogen cycling by returning nutrients to the soil through urine and dung, fertilizing surrounding vegetation.
- 02
Wallowing behavior associated with bison grazing creates shallow depressions in soil that collect water and support distinct plant and invertebrate communities.
- 01
Bison grazing creates patches of short, intensely grazed grass interspersed with tall ungrazed areas, increasing plant diversity across grassland ecosystems.
