MANAGEMENT ISSUES: TANZANIA’S COASTAL FORESTS 2011 several regions more than 300 km distance from Dar es Salaam, and the transport by rail from Tabora is over 1,000 km from Dar es Salaam. Considerable amounts of charcoal came from the coastal forest landscapes in 2007 (Figure 19), a situation that continues today.

Logging using pit sawing techniques occurs in those Coastal Forests where commercial timber trees remain. Many forests have already been logged to exhaustion for the usual commercial timber trees but are ever threatened by further logging when commercial attention shifts to new species. Particularly heavy exploitation for round wood export recently occurred in the Coastal Forests of the Rufiji, Kilwa and Lindi Districts of Tanzania, although this has now been stopped to a limited extent. Although some of this logging is undertaken using licences obtained from the relevant authorities, most is illegal. Logging of the valuable trees is often the first major disturbance to a forest, which then progresses to fire wood collection and charcoal burning, and in the worse cases to clearance for agricultural use. Studies within 10 forests from Dar es Salaam south to the Matumbi Hills (Ahrends 2005) have shown that logging of the highest value trees is concentrated more than 150 km south of the city – for the simple reason that these high value timber species have already been exploited in the forests closer to Dar es Salaam (Figure 20).

Some other fires are started accidentally, for example from cigarettes thrown from passing vehicles or by pedestrians. Fire can invade lowland
