The case study evaluated the use of SMART-based Law Enforcement Monitoring (LEM) as a tool to improve anti-poaching patrols across four protected areas (PAs) in the Russian Far East, critical for Amur tiger conservation. Poaching persisted because there was demand for tigers and their prey, opportunities to hunt them inside and outside the protected areas, and challenges in enforcement efficiency. The interventions focused on combating wildlife crime by implementing the SMART law enforcement monitoring system, increasing patrol effort and effectiveness, and reducing predictability of patrols. Patrol teams used GPS to record movements and paper forms to record violations, threats, and wildlife sightings. The collected data was also used to evaluate performance, set targets, and provide feedback. They also implemented a performance-based bonus system for members of the patrolling team to increase patrolling effort. As a result, over a four-year period, the project noted an increase in patrol effort and a partial reduction in threats. Poaching rates and firearm confiscations declined in some areas, but trends were inconsistent. Although they did not detect clear trends in ungulate numbers, tiger populations remained stable or increased, suggesting that poaching of tigers may be more limiting than prey depletion. The intervention was promising because SMART monitoring enabled standardized tracking of patrols and threats, supporting data-driven decision-making. It allowed achievement of the short-term goal of improving patrolling quality and reducing threats to wildlife. However, long-term conservation goals, such as increasing tiger numbers to 1 individual/100 km² at each study site, and prey numbers couldn’t be achieved. Ultimately, this study determined that further development of success indicators is necessary to properly evaluate and redirect anti-poaching efforts.
