post_content: In the summer of 2008, Jay Vavra and a group of High Tech High students traveled to Tanzania on a safari with a purpose—to combat the African Bushmeat Crisis, the illegal trade of meat from protected species, usually disguised as meat from a lawful origin.
Over the course of three years, students in Dr. Vavra’s biotechnology course studied the bushmeat trade and conservation forensics. They developed and practiced ways of identifying species via DNA barcoding, a technique they hope will aid scientists, environmental groups, and prosecutors in tracing illegal bushmeat back to its localized animal populations. While in Tanzania, the HTH team’s focus shifted from animals to people; they filmed and interviewed tribesmen and park officials talking about their lives and how poaching affected them. They presented their work to scientists and began an exchange of ideas for combating the crisis and developing education programs in East Africa and the United States. They returned home with hours of documentary footage and a greater understanding of wildlife conservation practices, the effects of illegal hunting on biodiversity, and the challenges being faced by those hoping to prosecute poachers.

Maasai tribesmen, photographed by HTH junior Steve Pye. The pastoralist Maasai tribe at Oldonyo Sambu, the mountain near our base camp, taught us much about coexisting with surrounding wildlife, including how to identify different animals’ tracks and scat. On our way to a dried out watering hole, we spotted fresh lion tracks, giraffe droppings, and foliage trampled by elephants. It was incredible to see evidence of so many different species in one small area.

While wild meat can be differentiated from domestic meat by smell and look, species-specific identification is usually impossible. Nelson Mwakafwila, a Tanzanian National Park Ranger, noted that the meat of a rare animal such as the Topi or Oryx can easily be mistaken for that of common gazelle or zebra.

The Hadza, a hunter-gather tribe, taught us a great deal about how to survive on the land. Following a lesson on arrow-making they took us along on a hunt. While we did not witness a kill, we learned that when a kill is made, the Hadza people set up camp and cook all of the meat on the spot. This allows everyone to benefit from one kill, rather than making several kills and not utilizing all of the fresh meat. The Hadza understood that their survival relies on keeping wildlife abundant.
Siagi, an elder of the hunter-gatherer Hadza tribe, photographed by Jay Vavra. Interviews with the Hadza tribe were challenging, as we needed translation from English to Swahili to Hadzabe, a beautiful language filled with clicks and pops. Our interview with Siagi went beyond words. When asked how tribesmen communicate with each other during the hunt, Siagi showed us a variety of signals and acted out a series of hunts. It was as if the lion or cape buffalo, and Siagi’s hunting partners, were really there.
An encounter with a great African elephant (tembo in Swahili) in the Tarangire National Park, photographed by Jay Vavra. These gentle giants would get frighteningly close to the vehicles, trotting along beside us and on one occasion, when we accidentally separated a baby from its mother, trumpeting behind us in hot pursuit. Observing the tembo in their natural habitat solidified our commitment to help preserve such animals and their environments.
Iraqw children with HTH senior Alex Bozzette, photographed by Jay Vavra. HTH students discovered that juggling was a great way to engage with people, particularly children, and begin conversations about wildlife conservation. Each member of our expedition realized that education was key to solving the bushmeat crisis; we emphasized that live animals had much greater worth than dead animals.

While documenting the wildlife conservation practices of the agriculturist Iraqw people, we learned that the Iraqw believed chameleons were poisonous. After seeing our excitement in holding and photographing the harmless reptiles, a group of Iraqw children ran ahead on our path through the forest and gathered a dozen chameleons for us. They later vowed to not kill these lizards, but to help protect them and to tell others they are good.
Lazarus Saruna, park warden & anti-poaching commander of Tanzania National Park, photographed by HTH sophomore Tyler Taylor. We had the opportunity to interview Lazarus after a chance meeting at a watering hole. He discussed the challenges in patrolling such vast areas, and emphasized the importance of techniques like ours in identifying bushmeat so that poachers could be prosecuted in court. Two weeks after our expedition we heard from Lazarus; he encountered a poaching camp containing slaughtered and partially processed animals. He estimated twelve zebra, six wildebeests and two impala.
Scorpion, photographed by HTH junior Steve Pye. Senior Megan Morikawa writes, “Tanzanian nights were filled with all sorts of surprises. From strange noises in the bush, to glowing eyes, to a great diversity of arachnids and insects, the students got to experience the true night time of Africa, when the animals take over. With caution and a critical eye, students learned not only to master their fear of the African night, but to appreciate each creature for their unique adaptations. The scorpion carries a protein which will fluoresce under UltraViolet light. Students got to witness this up close one night in the Yaida valley.”
