Ndutu, located in the southern part of the Serengeti-Mara ecosystem straddle in the Ngorongoro Conservation Area (NCAA) and Serengeti National Park(SNP), both Unesco World Heritage sites. Ndutu plays a vital role in the Ecosystem particularly from January to March, when it becomes the primary calving ground for the wildebeest migration. During this period, more than 400,000 wildebeest calves are born in just a few weeks, making it one of the most crucial life stages in the migration cycle.
This year, the calving season started earlier than usual, with reports of newborn wildebeest appearing in Ndutu as early as the 28th of December. This shift may be influenced by rainfall patterns and environmental factors that trigger the rutting bout.

The Ecological Importance of this Landscape or The Ecological Significance of Ndutu: From Calving to Predation
Nutrient-Rich Grasslands
Ndutu’s short grass-plains, enriched by volcanic ash from the Ngorongoro highlands, provide essential minerals and nutrients that support lactating mothers and strengthen newborn calves. This makes it an ideal calving site, ensuring the highest possible survival rate for young wildebeest.
A Predator-Prey Hotspot
With such a large concentration of vulnerable newborns, Ndutu becomes a predator hotspot. Lions, leopards, cheetahs and hyenas patrol the plains, taking advantage of the abundant easy prey. This predator-prey interaction is vital for ecosystem-balance, ensuring that only the fittest survive to continue the migration.
Scenic Acacia Woodlands and Seasonal Lakes
Beyond the open plains, Ndutu features Acacia (aka Vachellia) woodlands that provide food and cover for species like giraffes, elephants and cover for leopards. It is also home to Lake Ndutu, a seasonal soda lake that attracts migratory birds, including large flocks of lesser flamingos. During the wet season, the lake becomes a crucial water source, attracting thousands of grazing herds and birds.
A Birdwatching Paradise
With over 400 bird species recorded, Ndutu is a paradise for birdwatchers. The diverse habitat, from woodlands to lakes, support both resident and migratory birds, making it a year-round destination for bird enthusiasts. This area’s unique environment provides abundant feeding grounds and nesting sites for a variety of species.
The Role of Climate and Seasonal Changes
Ndutu’s landscape is heavily influenced by seasonal changes. During the wet season, the area becomes lush and green, providing ample food and water for the migratory herds. However, during the dry season, the landscape transforms becoming unhospitable and challenging wildlife to adapt. The dynamic seasonal rhythm creates a constantly changing environment, contributing to the ecological complexity and resilience of the area.
Ndutu as a Research Hub:
Ndutu is a focal point for scientific research on wildlife behaviour, ecology and conservation. This ongoing research contributes valuable insights into the broader dynamics of the Greater Serengeti- Mara ecosystem, supporting effective conservation strategies for the future.
