  abstract = {{I}n situ conservation of tropical forests often requires restricting human use and occupancy within protected areas by enforcing regulations. {H}owever, law enforcement interventions that seek to prevent deforestation rarely have been evaluated. {C}onservationists increasingly recognize the need to measure the effectiveness of their interventions, using an indicator of biodiversity change, such as rate of deforestation, and a counterfactual approach that addresses a fundamental question: what would have happened had there been no intervention? {T}his study examines how law enforcement can mitigate habitat loss from small-holder coffee growing by comparing 34 years of empirical data on deforestation rates and coffee prices across a zone of high law enforcement and a zone of low law enforcement using satellite imagery, ecological data, interviews, and {GIS} modeling.. {I}n the early 1980s strong law enforcement efforts were found to reduce deforestation inside {B}ukit {B}arisan {S}elatan {N}ational {P}ark ({BBSNP}), southwest {S}umatra. {H}owever, law enforcement efforts were weak in remote areas of {BBSNP}, where high coffee prices spurred rapid deforestation. {F}urthermore, law enforcement efforts were reversed by the 1997-1998 {A}sian economic crisis. the fall of the national president, and by new regulations surrounding regional autonomy. {T}hese findings indicate that law enforcement is critical but insufficient alone. {T}hey also highlight that rising costs of agricultural commodities can be detrimental to tropical forests and their associated biodiversity. {I}n the long run one must act to decrease the incentives for coffee cultivation. {A} multi-faceted strategy that includes law enforcement and incentives to reduce poverty around {PAS} is proposed.},
