Major Threats

The majority of documented corridors in the country now seem to be in a critical condition.

That is, based on current rates of habitat change, they are estimated to have less than 3 years remaining before they disappear.

Five corridors are in extreme condition and could either disappear within 1 year unless immediate action is taken, or have already been closed.

Corridors are being destroyed by:

  • rapid agricultural expansion
  • unplanned land use strategies
  • unmanaged natural resource extraction
  • increased bushmeat trade and the building of roads

At the root of all these threats is a rapidly increasing human population.

In the short-term, unless action is taken to manage these activities, Tanzania’s protected areas will become isolated; a situation likely to have serious implications for economic development including the sustainability of the tourist industry.
