A base for long-term mountain observationThe core instrumentation area is located within the Afromontane Research Unit’s 250 ha Alpine Lease with Witsieshoek Mountain Lodge. Situated on the Free State summit plateau, the lease provides secure access to high-altitude grasslands, wetlands, streams and elevation transects.
Witsieshoek-ARU Alpine Base
The Witsieshoek-ARU Alpine Base is situated at approximately 3 069 m near the head of Namahadi Pass. Created through the restoration of the historic Namahadi border-post buildings, it provides a unique platform for research and extended field visits in the alpine zone. The facility can accommodate research groups and supports access to the Mont-Aux-Sources plateau, the Chain Ladders, uThukela Falls and nearby monitoring sites.
Monitoring networkLong-term observations are being developed across an elevation gradient extending from the lower mountain environment to the alpine summit. Infrastructure includes automatic weather stations and project-specific monitoring of soil moisture, vegetation, biodiversity and water. Standardised observations allow researchers to compare change across elevation, land use and ecosystem condition.
Field safety
The high Drakensberg is remote, and weather conditions can change rapidly. Access to the Alpine Lease and Base must be arranged in advance. Visitors should be properly equipped and receive appropriate access and safety guidance.
