For more than fifty years, the Natural History Museum of Denmark – a founding partner and co-manager of UEMC – has been at the forefront of biodiversity research in the Eastern Arc Mountains, revealing an extraordinary concentration of endemic species. These discoveries played a decisive role in recognising the global conservation importance of the area and contributed to its designation as a National Park in 1992.
A major milestone in documenting Udzungwa’s invertebrate fauna came in 2014, when the COBRA protocol was applied across multiple habitats. The COBRA (Conservation Oriented Biodiversity Rapid Assessment) protocol for invertebrates is a standardized, time-efficient method designed to assess biodiversity by combining multiple sampling techniques—such as pitfall traps, beating, and sweeping—to target various taxonomic groups (especially arthropods) in a short time. The survey revealed an exceptional spider community, with 631 documented species – 85% previously unknown to science – and more than 60 endemic millipedes.
Our invertebrate monitoring focuses on understanding species diversity across habitats and elevations. Using innovative and cost-effective methods, we study patterns of biodiversity and how they respond to environmental change.
Results show that biodiversity changes significantly with altitude, with high-altitude habitats hosting unique and often highly specialized species. These species are typically more vulnerable and less able to disperse, making them especially sensitive to environmental change.
This highlights the critical importance of protecting and restoring high-altitude habitats—even small conservation actions can make a big difference in safeguarding rare and endemic species.
Because of their sensitivity and short life cycles, invertebrates act as early warning indicators of ecosystem health. This makes them essential for detecting change, guiding conservation action, and protecting fragile habitats—especially in high-altitude areas where unique species are most at risk.
