A ranger since 2015, Mário Cristóvão became a patrol leader following extensive training. He stands out for his work in the community-led “Tchova Tchova” initiative, which since 2018 has reduced poaching of elephants and lions to zero in the L5 South block. In 2025, he survived an insurgent attack, demonstrating courage and resilience, and continues his recovery with an inspiring spirit.
