The Eastern Arc Mountains of Tanzania show exceptional endemism that is threatened by high anthro- pogenic pressure leading to the loss of natural habitat. Using a novel habitat conversion model, we pres- ent a spatially explicit analysis of the predictors of forest and woodland conversion in the Eastern Arc over 25 years. Our results show that 5% (210 km 2 ) of evergreen forest and 43% (2060 km 2 ) of miombo woodland was lost in the Eastern Arc Mountains between 1975 and 2000. Important predictors of habitat conversion included distance to natural habitat edge, topography and measures of remoteness. The main conservation strategy in these mountains for the past 100 years has been to develop a network of pro- tected areas. These appear to have reduced rates of habitat loss and most remaining evergreen forest is now within protected areas. However, the majority of miombo woodland, an important source of eco- system services, lies outside formal protected areas, where additional conservation strategies may be needed.

The Cancún Agreements provide strong backing for a REDDC (Reducing Emissions from Deforestation and Forest Degradation) mechanism whereby developed countries pay developing ones for forest conservation1. REDDC has potential to simultaneously deliver cost-effective climate change mitigation and human development2–5. However, most REDDC analysis has used coarse-scale data, overlooked important opportunity costs to tropical forest users4,5 and failed to consider how to best invest funds to limit leakage, that is, merely displacing deforestation6. Here we examine these issues for Tanzania, a REDDCcountry, by comparing district-scale carbon losses from deforestation with the opportunity costs of carbon conservation. Opportunity costs are estimated as rents from both agriculture and charcoal production (the most important proximate causes of regional forest conversion7–9). As an alternativewe also calculate the implementation costs of alleviating the demand for forest conversion—thereby addressing the problem of leakage—by raising agricultural yields on existing cropland and increasing charcoal fuel-use efficiency. The implementation costs exceed the opportunity costs of carbon conservation (medians of US$6.50 versus US$3.90 per Mg CO2), so effective REDDC policies may cost more than simpler estimates suggest. However, even if agricultural yields are doubled, implementation is possible at the competitive price of US$12 per Mg CO2.
