Land rents for Mabira Forest Reserve in 2001. Rents have been converted to U.S. dollars. Darker areas indicate higher land rents, which are mostly in the western part of the reserve. Areas in red were deforested between 1986 and 2001. The local road network is also shown, as well as a 2001 Landsat image of the surrounding agricultural landscape. Areas in gray were deforested before 1986 and are now regenerating.

Total cost-revenue curves under various scenarios for avian biodiversity conservation at the Mabira Forest Reserve. TC, the current total cost curve; TB, the current total revenue curve; TC′, the total cost curve under the growth scenario; TB′, the total revenue curve with optimal entrance fees; S₀, the current equilibrium supply of forest bird species; S₁, the equilibrium supply under the least favorable scenario; S₂, the equilibrium supply with changes in the total cost and total revenue curves; S₃, the equilibrium supply under the most optimistic scenario; M, the total cost curve with land values held constant ($114.00 per hectare).
