Udzungwa
Landscape Strategy
Protecting a globally unique ecosystem, together.



The Udzungwa Landscape Strategy (ULS) is a long-term, collaborative effort to protect one of Africa’s most extraordinary biodiversity hotspots, the Udzungwa Mountains of southern Tanzania.
ULS brings together communities, protected area managers, civil society organisations, researchers, and donors to conserve nature and improve human well-being.

Our Mission & Vision
We work to conserve the unique Udzungwa Mountains landscape through a transparent, inclusive, and long-term strategy that empowers communities and protects biodiversity. Our vision is a resilient Udzungwa where thriving ecosystems and local people coexist and sustain one another—now and for generations to come.

Why Udzungwa
Over 2,500 plant and 120 mammal species
Home to 46% of Tanzania’s endemic vertebrates
Supports the livelihoods of >250,000 people
18 rivers originate in the Udzungwa Mountains, sustaining hydropower stations that generate over 30% of Tanzania’s electricity

The Udzungwa Mountains are globally recognised for exceptional biodiversity, including thousands of arthropod species found nowhere else on Earth. In just 3.5 hectares of forest, researchers recorded 631 spider species, with 85 per cent new to science—one of the highest documented densities of spider diversity worldwide.
To strengthen evidence-based conservation, long-term invertebrate monitoring is underway in Kilombero Nature Forest Reserve and Udzungwa Mountains National Park, led by the Udzungwa Ecological Monitoring Centre in collaboration with protected area authorities. Permanent monitoring plots and standardised seasonal surveys are generating baseline and trend data on insects, spiders, and other arthropods.
These species respond more rapidly to habitat disturbance and climate variability than vertebrates, making them effective early indicators of forest health. Integrating this data into management planning strengthens adaptive decision-making and supports Monitoring, Evaluation and Learning under the Udzungwa Landscape Strategy.
Science is guiding long-term protection across the Udzungwa landscape, ensuring that even the smallest species inform the future of conservation.
