Conversion from primary forest to other land uses, 1985-2007 Conversion from primary forest to other land uses, 1985-2007
The main driver for forest loss on peat areas in the Leuser Ecosystem was oil palm development between 1985 and 2007, while for forest on non-peatlands other land uses than oil palm contributed more to land use changes.

Ecosystem services value for the Leuser Ecosystem Ecosystem services value for the Leuser Ecosystem
Values for the various non-carbon ecosystem services (water, regulation of floods and landslides, fisheries, prevention and limitation of fires, agriculture, tourism, and non-timber forest products (NTFP) and biodiversity) were calculated with a discount rate of 4% over a 30-year period. Total value for ecosystem services beyond climate regulation being USD 3,735/ha.

Distribution of benefits under different land use scenarios in the Leuser Ecosystem Distribution of benefits under different land use scenarios in the Leuser Ecosystem
Net present value (NPV) is in millions of USD over a 30-year period (2000-2030) at a 4% discount rate. The NPV for local communities under a deforestation scenario would be 3,132 million USD and under a conservation scenario 5,341 million USD. The analysis shows that the local community would benefit most from a scenario under which the forest is conserved, negative effects on ecosystem services are avoided and payments for ecosystem services ar...

Conservation areas and the Leuser Ecosystem Conservation areas and the Leuser Ecosystem
Approximately 50% of Sumatran orangutan habitat is inside conservation areas directly managed by the Ministry of Forestry, and 78% lies within the boundaries of the vast Leuser Ecosystem Conservation Area.

Water catchments Water catchments
Orangutan habitat overlaps the catchments of 44 major rivers in Sumatra, each of which reaches the coast and discharges into the sea. Thus it is very important to guarantee proper functioning of ecosystem services related to water.

Migration of grassland birds in America Migration of grassland birds in America
The grasslands of Argentina, Bolivia, Brazil, Paraguay, and Uruguay in southern South America represent important habitat to numerous migratory and resident bird species. These birds play vital roles in the ecosystem by dispersing seeds and controlling insect populations. Some species, such as the Buff-breasted Sandpiper (Tryngites subruficollis), migrate some 20,000 km from their breeding grounds along the Arctic coast to their non-breeding rang...

Highway threaten Serengeti wildlife Highway threaten Serengeti wildlife
This graph shows proposed commercial roads across the Serengeti and surrounding region in 2010. However, following intense international pressure, the Tanzanian Government announced in 2011 that it will favour an alternative route to the South, outside the park. Some projections suggest that if the road were built, numbers may fall to less than 300,000 (Dobson and Borner, 2010), others that the herd could decline by a third (Holdo et al., 2011), ...

Cheetah and Wildebeest in East Africa Cheetah and Wildebeest in East Africa
Protecting the Cheetah’s range also benefits other migratory wildlife, including those not currently protected by international agreements such as Appendix I of the CMS. The Serengeti- Mara-Tsavo landscape, for example, is home not only to a globally important population of Cheetahs, but also to vast numbers of migratory Wildebeest, Zebra, Eland and Thomson’s Gazelle. In 2011, the Tanzanian government ensured that the proposed commercial road n...
