Bryophytes of Ausable Chasm

Abstract

We surveyed bryophyte diversity along the Rim, Inner sanctum, and Little Dry Chasm trails at Ausable Chasm. Using 50cm2 quadrats comparisons were made between bryophyte Genera. Results suggest that the Dry Chasm trail had the greatest bryophyte Genera richness (S=10) and the common species were also found along the Rim trail. All four Genera observed on the Inner Sanctum trail were unique to that trail and likely reflect the complexity of rocky substrate.With further study and long-term monitoring, the findings of this study may have significant implications for human impact on bryophyte communities in this unique tourist attraction.
