What Happened?
In 1987, 30 bison were introduced to Konza Prairie, leading to a 103% increase in native plant richness over 29 years. The study highlights the benefits of bison grazing.
Why it matters
The restoration of bison grazing could enhance biodiversity in grassland ecosystems.
Key points
- In 1987, 30 bison were brought to Konza Prairie from Fort Riley.
- Native plant species richness increased by 103% locally and 86% across catchments over 29 years.
- Bison grazing was linked to sustained increases in plant diversity, even after extreme droughts.
- Bison grazing reduced dominant grass cover, allowing more native species to thrive.
- Compared to cattle, bison grazing resulted in greater increases in native plant richness.
Key insights
- Bison grazing may help ecosystems recover from drought due to increased plant diversity.
- The study suggests that native herbivores like bison play a crucial role in maintaining prairie health.
- Long-term ecological research at Konza Prairie provides valuable insights into biodiversity management.
