Safari in Ndutu: Why the Impala Rules Africa’s Edges
While camping in the Ndutu region of Tanzania, I rose from my bunk and slowly unzipped my tent. A bachelor herd of impala, numbering maybe 15 individuals, stood about 40 feet away. It was raining and none of us were going anywhere. I was content to sit and peek. They stood under the dripping scrub, matted and wet, and looked back. I smelled their odor. Nostrils flared. They were undoubtedly thinking the same thing. It was a good place to be and the right time to be there.
Ndutu Safari: Life in the Serengeti Transition Zone
As it turns out, the Ndutu region functions as a transition zone between the sweeping, short-grass plains of the southern Serengeti and the wooded volcanic highlands of the Ngorongoro Conservation Area.
While seasonal visitors like wildebeests, zebras, and their tag-along predators migrate into Ndutu on an annual schedule, the impala is a permanent resident here.
What is an Ecotone? The Power of “The Edge”
In wildlife management, “the edge,” or more formally, the ecotone, is the boundary where two different habitats meet.
In North America the white-tailed deer are edge-masters. They love hanging out where forests meet suburban backyards, mostly so they can munch on expensive landscaping. They thrive by taking advantage of resources from more than one world.
In Africa the impala (Aepyceros melampus) are edge-masters. For these antelopes, crossing lines isn't a zoning mistake; it’s a survival strategy built around three distinct advantages:
1. Diverse Food Options
Open plains offer fresh grasses, while thick forests offer nutritious tree leaves and seed pods. Because impalas are mixed feeders, they switch effortlessly between grazing on the ground and browsing on woody shrubs depending on the season.
2. Predator Protection
If a plains predator like a cheetah chases them, the herd can quickly dart into the thick brush to break the cat's line of sight and high-speed momentum. If a thicket predator like a leopard corners them, they can burst out into the open plains where they have room to outrun them.
3. Climate Control
The Ndutu “edge” gives the herd options. They can bask in the warm, sunny open grasslands during chilly mornings, and quickly retreat into the deep shade of the scrub trees during the blistering midday heat.
Watching the impala navigate the elements made me appreciate my own ecotone even more. I zipped up the canvas door and retreated to my dry bunk.
