Making Migration Impossible?

Up to two million wildebeest and half a million zebra migrate across the Serengeti each year.

Considered the greatest natural wonder of the world, Africa’s Serengeti National Park is ground zero for massive wildlife migrations through Tanzania and Kenya. Each year, millions of wildebeest, zebra, elephants, rhinos, gazelles and predators like cheetahs and lions teem across the landscape as far as the eye can see. They move in search of rain, instinctively following paths established over thousands of years of evolution.

But last May, the Tanzanian government announced plans to build a 300-mile highway through the northern part of the park. Tanzania’s president, Jakaya Kikwete believes the $480 million project would improve transportation and boost economic activity by linking two of its key towns — Arusha, near Kilimanjaro and Musoma on Lake Victoria.

Unfortunately, the road could have devastating consequences for migrating wildlife, and the African economies who depend on the key tourist attraction. Kenya is opposed to the Serengeti road project, worried how it would affect the annual wildebeest migration.  More than 100,000 tourists visit the country’s Maasai Mara National Reserve during the migration months between July and October, and any interruption is likely to hurt Kenya’s economy.

“Wildebeest have a problem crossing roads which have heavy human and vehicle traffic, there is nothing elsewhere in the Serengeti with this high capacity for traffic,” said Mr Gideon Gathaara, a Kenyan Ministry of Wildlife official.

Scientists say that a road like this could lead to the collapse of the Serengeti ecosystem, as well as  tourism in the region. Though the proposed road would be gravel, the presence of increased traffic would disrupt wildlife to the point of their avoidance of the area and would lead to roadkill, especially at night. And it’s not only zebra and wildebeest at risk – vehicles pose a huge threat to carnivores like wild dogs, even big animals like rhinos. A fence would be even more damaging to wildlife, entangling some animals and isolating others. Baby elephants that are unable to step over the same fences that grown elephants can are often abandoned, the rest of the herd pushed on in search of water. Eventually, the road would most likely be paved anyway.

Several conservation experts have publicly condemned the plan,  as has the United Nations World Heritage Committee. Internationally known wildlife biologist Richard Estes said the price of a road through the Serengeti is too high. “There’s not only the hazards of animals being killed by vehicles, which is serious, but more dangerous is the unplanned development that will follow — the building of towns and strip development — which is increasing human influence and access. The poaching is already serious and this will make it a whole lot easier.”

Construction of the highway is slated to begin in 2012. That’s not a lot of time to convince officials to change their plans. Can we save the Serengeti – or will this great migration be relegated to the pages of history?

    Could they incorporate underpasses in the highway plans? Gullies that the wildebeest and other migrating animals could use while the vehicles travel on the road could save lives. Just an idea.

    These animals have been doing this for 1,000 of yrs. Why destroy something so beautiful for the convenience of a road? Part of the allure of Africa is it untouched grasslands….tourist come to Africa just for those reasons. They are willing to bring in top dollar for that beauty of the land and the animals.

    Hi Vicki – Unfortunately, there is no way to mitigate the impacts of this highway. Migration is hectic, frenzied and always different. There would be no amount of crossings that would allow safe passage of this many animals, moving this quickly and sporadically. Also, the herds may be so disturbed by the presence of a highway, they may not come near it, thus stunting the migration. Finally and most tragically, even if we could safely pass animals under the road, the road itself will be a drive-through for poachers. Even now, with no road, poachers are illegally killing thousands of animals. With a highway, they would be virtually unstoppable. Rare species like rhino, elephant and lions would be slaughtered. But stay tuned and don’t give up hope!

      If cost is also in consideration then beacuse you are thinking Tanzania do a Kenya and Tanzania safari.You could start with either of these two countries.The migration happens in three parks serengeti (Tanzania) part of ngorongoro(Tanzania) and masai mara (kenya).*Note the migration is a natural event and the timing varies month by month; year by year. But here is how it generally runs.December, January, Feburary, March: During these months the southern Serengeti and the Conservation Area are inhabited by enormous herds of wildebeest and zebra. The great herds graze on rain ripened grass.This is the best time to visit the Serengeti. (Tanzania)This is also the calving season between late January through mid March when over 80% of the wildebeest give birth over a period of a couple of weeks the herds concentrate at the Ndutu and Salei plains (Southern Serengeti / Ngorongoro Conservation Area) attracting the attention of predators like lion, cheetah and hyena.April, May: During the months April and May the depleted plains are unable to sustain the huge herds. over 1.5 million wildebeest not to mention zebra etc. The migration, sweeping west and north, moves from the short grass plains of the southern Serengeti / Ngorongoro Conservation Area to the long grass plains and woodland of the Serengeti’s western Corridor, almost to Lake Victoria.This period is often during the long rains and is considered off season for wildlife viewing in east Africa as roads are often muddy. Ndutu Safari Lodge, Kusini Camp and the Serengeti Serena Lodge are fine for wildlife viewing during this time. So are campsites in the Ndutu/Naabi area.Other things you might consider while on your African safari would be a beach experience. African beaches are pure white and also places like mombasa in Kenya offer a rich history and fun activities. Imagine sailing on an arab dhow (sailing ship) at sunset to visit an old city of mombasa learning its history from the arabs to the portugese who once inhabited this place then ending up with candle lit dinner at fort jesus under the african stars with the waves roaring close. It’s called mombasa by night safari.Other great places to visit are Zanzibar in Tanzania.

    Hi Victoria – You are right. Tourism brings millions of dollars to Tanzania and this highway would indeed destroy what the tourists are coming to see. The Great Migration is considered the greatest natural wonder of the world. Can you imagine throwing that away? That’s why thousands of travel agents have signed a petition to stop the highway and have pledged to take their clients elsewhere if Tanzania goes through with the highway. Check it out here:
