Protection beyond park boundaries: On the impact of systematic patrolling in Divisional Forest Office, Sarpang, Bhutan

Abstract

Abstract Protected areas and biological corridors play a crucial role in conserving biodiversity and promoting connectivity between habitat patches. Bhutan, known as a stronghold for tigers (Panthera tigris), has dedicated a significant portion of its land to a network of protected areas and biological corridors. However, these areas face risks from illegal activities, posing challenges for their management. To address this, the Department of Forests & Park Services in Bhutan deployed an adaptive management framework, informed by the Spatial Monitoring and Reporting Tool in 2016 in the Divisional Forest Office, Sarpang, an important corridor area outside of official protected area boundaries. This study analyses 5 years of data (2017–2021) recorded through a monitoring tool to assess changes in ranger activities and on‐ground observations. The results show improved data availability, increased patrol effort, enhanced monitoring of wildlife, and a reduction in threat detection over time. Furthermore, camera trap surveys targeting tigers reveal a potential increase in the number of individual tigers utilizing the corridor since the adoption of the tool and other management actions. These findings highlight the effectiveness of these efforts in a critical wildlife corridor.
