Jaguars have recently been spotted crossing the U.S.-Mexico border for the first time in about 40 years. This is good news to conservationists working to create a permanent home in the feline’s native range—a corridor that stretches from Mexico to Argentina.

But the task is not as simple as setting land aside. While camera traps and satellite tags gather crucial population data, sensitive political battles are waged with private landowners and governments. The truth is, aiding predators is a hard sell.

Wild Chronicles follows one man’s attempts to save the largest cat in the Americas, and discover what scientists are hoping will allow jaguars, and the people that share their land, to thrive.

  1. Approximately how much jaguar habitat has been lost to human development?

    • Answer

      More than 1.5 million acres of jaguar habitat has already been lost to human development.

  2. The proposed "jaguar corridor" would stretch from Mexico to Argentina. Where is the most critical area of the corridor?

    • Answer

      The swampy Pantanal region of Brazil is the largest and most important area of the corridor.

  3. How large can a jaguar of the Pantanal grow?

    • Answer

      A jaguar of the Pantanal can grow to 23 kilograms (150 pounds).

  4. Why do ranchers oppose the proposed jaguar corridor?

    • Answer

      Ranchers say jaguars prey on their cattle.

  5. What health statistics do scientists measure in a captive jaguar?

    • Answer

      Scientists measure the jaguar's temperature, pulse, and respiration rate.
