The Sangha Tri-National (TNS)
Biological surveys conducted by WCS and WWF in the late 1980s and early 1990s highlighted the strong biological wealth of the Sangha region Tri-National Landscape threatened by uncontrolled logging and illegal hunting activities for commercial purposes. During the same period, the two conservation NGOs established field projects in the different sites.
The governments of the countries concerned, quickly realized the importance of the Sangha region in the world and committed to create several protected areas. In 1990 the Dzanga-Ndoki National Park and Dzanga-Sangha Special Reserve in CAR are ranked and, in 1993, the Nouabale-Ndoki National Park in Congo is classified. In Cameroon, the Lobéké area is designated “Essential Protection Zone” in 1995 and its ranking as a national park took place in 2001. The fact that the three conservation areas are attached and share the same types of vegetation, and the same local communities – in particular, the forest peoples who share the same cultures and traditions and are faced with similar problems – provided an excellent opportunity to develop a cross-border conservation program.
Following the Central Africa Heads of State Summit of 1999 in Yaounde with the subsequent birth of COMIFAC, the Governments of Cameroon, Central African Republic and the Republic of Congo made their commitment by signing a Cooperation Agreement to establish and collaboratively manage the transboundary forest complex called the Sangha Tri-National (TNS).
