Invasive Iguanas Devour Crops in Taiwan's Red Bean Heartland

Farmers in Pingtung face mounting losses as a surge in green iguanas decimates fields, turning a vital agricultural region into an unexpected buffet.

Farmers in Wandan Township, Pingtung County, Taiwan, are facing significant challenges as an invasive species, the green iguana, has seen a dramatic population increase, leading to widespread crop damage. As the red bean planting season begins, growers are experiencing distress rather than anticipation due to the reptiles' voracious appetite for their produce.

A recent operation organized by the service team of County Councilor Hong Tsung-chi saw over ten individuals deployed to five different fields in the early hours of the 18th. In a single night, they successfully captured more than 140 green iguanas, highlighting the severity of the infestation.

One particularly hard-hit area is farmland adjacent to a cemetery. A female farmer, who cultivated two tenths of a hectare of red beans last year, witnessed her newly sprouted crop completely consumed by the iguanas. This year, she opted to plant chili peppers, hoping to avoid the iguanas' feeding habits. However, her efforts were in vain as the young chili sprouts were also devoured as soon as they emerged from the soil. Witnessing her hard work go to waste, she sought assistance from the councilor's office.

Upon receiving the report, Hong Tsung-chi immediately mobilized resources for a capture operation. In the affected farmer's land alone, over 40 iguanas were caught, a situation described as "catching iguanas faster than catching fish." Councilor Hong emphasized the alarming reproductive rate of the green iguanas, noting that they not only threaten farmers' livelihoods but also disrupt the ecological balance. He warned that unchecked proliferation could severely impact Pingtung's crucial red bean industry.

He stressed that sporadic efforts by individual farmers or local volunteers are insufficient to curb the expanding population. Effective control requires collaboration between the government and the community to address the issue at its source. He urged farmers to report any sightings of green iguanas immediately by calling the Pingtung County Government's hotlines, 1959 or 1999, so that relevant authorities can provide assistance and mitigate the damage.

Red beans are a significant economic crop for Wandan, known as the "hometown of red beans," and consistently attract substantial orders. The current situation, where these valuable crops are being treated as a "feast" by invasive green iguanas, has left farmers feeling helpless and frustrated. Councilor Hong reiterated his call for the government to take this issue seriously, as it poses a threat not only to agriculture but also to the long-term ecological health of the region.
