About the Cass Mountain Research Area
The Cass Mountain Research Area (CMRA) is a 1,775-hectare research landscape owned and managed by the University of Canterbury in the upper Waimakariri catchment of the central South Island.
Located near Arthur’s Pass, the area encompasses two prominent peaks, Cass Hill (1,098 m) and Sugarloaf (1,359 m), along with river terraces, alluvial fans and a remarkable diversity of mountain environments.
From alpine slopes and scree fields to beech forest, wetlands, streams, grasslands and braided river habitats, the CMRA contains an exceptional range of ecosystems within a relatively compact area.
This diversity makes it an ideal outdoor laboratory for research, teaching and long-term environmental monitoring.
The wider upper Waimakariri Basin is one of New Zealand’s most diverse mountain landscapes, shaped by active geological processes and the dynamic interactions of rivers, glaciers, tectonic uplift and erosion.
Within a relatively small area, students and researchers can access braided rivers, alluvial fans, river terraces, alpine and subalpine environments, wetlands, beech forests and mountain ranges.
This exceptional diversity of landforms, habitats and ecological gradients makes Cass an ideal location for teaching and research, allowing learners to investigate environmental processes and ecological patterns firsthand while providing a natural laboratory for studies ranging from geology and geomorphology to ecology, hydrology, conservation and climate change.
Few locations in New Zealand offer such a rich setting for field-based teaching, interdisciplinary research and long-term environmental monitoring.
