ON THE EDGE OF EXTINCTION - C - THE JAGUAR (Panthera onca)

[Pckts]

Differences in the Southern Pantanal compared to the Northern
Southern Pantanal has a more harsh flood season, it's been more molested by farmers and Jaguars are harder to see there. To entice Jags to come out they do bait them in the South to get them to walk in front of their safari vehicles.

"But for people who want to see jaguars, the north is definitely the place to go to, especially around Porto Jofre"


But the South is where you want to go if you want to see Macaws, Peccary, Giant Anteaters, Tapir and Yellow Anaconda. My guess would be due to the fact that Jaguar numbers aren't as high, but that is only a guess.
Per Paulo, Jags in the South may not be as large as they are in the North but they are still plenty large, have solid numbers and have a strong prey base. But most likely due to the fact that they are a bit more intruded on by humans and deal with a heavier flood season, that may have something to do with it. I also believe the South doesn't have the same Caiman Population as the North does.
