Chacoan Peccary (Catagonus wagneri) Fact Sheet: Distribution & Habitat

Chacoan Peccary (Catagonus wagneri)


  • Endemic to the generally hot and dry Gran Chaco of western Paraguay, northwestern Argentina, and southeastern Bolivia
    • Torres et al. (2017) suggest the southern limit of this species extends farther south than previously thought
  • Distribution is fragmented, possibly due to intense hunting pressure following increased accessibility (i.e., development) of the Chaco.


  • A mosaic of xerophytic thorn forest, open woodland with dense grass and sparse cactus, and agricultural land.
  • Chacoan peccaries evidently adapt to land degraded by fire and overgrazed by livestock as long as ample food and cover are available and they are not overhunted.
  • Home ranges in Paraguay were 3.8-15.5 sq km; little overlap. Dispersing animals have occupied three discrete ranges and moved 4.6 km during a 9-month period. Movement within the home range is continual.
