Laqui started as a resident vaquero on the Northern Jaguar Reserve, along with his father, brother, and nephew. He has assisted visiting researchers since 2010, with particular interest in studying birds on the reserve. Laqui is trained in camera placement and maintenance, and today is responsible for checking motion-triggered cameras on the reserve and Viviendo con Felinos ranches. He also has experience with restoration techniques and tractor operation, and helps with gabion construction and invasive species removal as available. His son, José Ezequiel, participates in our Eco-Guardian program. Laqui is a recipient of the Disney Conservation Hero award.
Braulio Duarte López, Vaquero
Braulio is the eldest of our vaquero Laco’s sons and inherited his father’s work ethic and knowledge. He has an inner drive to work hard as a skilled albañil (handyman) and produces quality results. As a fulltime vaquero on the Northern Jaguar Reserve since 2015, Braulio builds with adobe, wood, and stone, collects rocks to make gabions, helps repair and install fencing, and assists with motion-triggered camera maintenance as needed. Braulio likes to spend time working as a leather artisan, making belts, scabbards, and repairing saddles.
Braulio Duarte Arvayo, Vaquero
The younger Braulio enthusiastically joined our ﬁeld team in 2017. He rapidly developed the skills to help with motion-triggered camera operation, as well as a passion and knowledge for wildlife. In addition to maintenance and restoration activities, Braulio helps with biological monitoring. While working on the Northern Jaguar Reserve, he has overcome his fear of snakes and can handle non-venomous reptiles, if needed, to move them out of harm’s way.
Heraclio “Laco” Duarte Robles, Vaquero
Laco, who works alongside his sons and grandson, patrols the Northern Jaguar Reserve to keep trespassers out and maintains fences to prevent wandering cattle from coming in. He is a traditional Sonoran vaquero, originally from Arivechi, and worked as the lead vaquero on these ranches since 1982. Laco has seen jaguars on more than a dozen occasions and knows this terrain better than anyone. He is also a local artisan and makes traditional leather lassos.
