Invasive Wild Boars Threaten Crops in Argentina’s Tres Arroyos and Pringles

Wild boars (jabalíes) originally introduced to La Pampa in the early 20th century are rapidly expanding into the border districts of Tres Arroyos and Pringles in Buenos Aires Province. Their high reproductive rate and adaptability have created large populations that move in groups weighing over 200 kg.

The animals damage agricultural production by damaging silobags, destroying maize, wheat and soybean crops, and breaking fences. They also pose safety hazards on roads and raise sanitary concerns, as hunters and consumers risk disease transmission from untested meat. Argentine law permits hunting with a permit from the Ministry of Agrarian Development, but control is difficult because the boars are fast, have keen senses, and reproduce quickly.

Local authorities report increasing economic losses for farmers and the need for costly replacements of damaged grain storage. The spread is linked to expanding maize cultivation, wildfires and the absence of natural predators, turning the issue into a broader environmental, agricultural and public‑health challenge across the region.
