Taiwan Drastically Reduces Invasive Cane Toad Population | Environment News

A concerted conservation effort in Caotun, Taiwan, has achieved remarkable success in curbing the population of the Cane Toad, a species listed among the world's top 100 invasive organisms. First identified in the area in 2021, these large, prolific amphibians posed a significant threat to the local ecosystem.

Cane Toads, native to Central and South America, were introduced as pets but quickly established wild populations after being abandoned. Their large size, capable of reaching 1.5 kilograms, and potent venom, coupled with their tendency to prey on native animals and compete with indigenous frog species, made them a serious ecological concern. By 2023, surveys indicated a staggering population of 35,883 Cane Toads in Caotun.

However, through collaborative removal and monitoring initiatives involving various government agencies, research institutions, and community associations, the tide has turned. The population has seen a dramatic decline, with the latest surveys in June showing fewer than 30 individuals remaining. This significant reduction is a testament to the effectiveness of the coordinated action taken.

Recognizing the ongoing threat, the public is advised not to capture Cane Toads themselves. Instead, any sightings should be reported immediately. Individuals can report findings through the "Taiwan Amphibian Conservation Volunteers" Facebook group or by contacting local authorities via the 1999 hotline. The Cane Toad was officially designated as a harmful invasive species in April 2024, and unauthorized capture, possession, or breeding can result in fines under the Wildlife Conservation Act.

If the public discovers Cane Toads in the wild, please take a photo and record the time and location, then promptly report it on the 'Taiwan Amphibian Conservation Volunteers' Facebook group, or call 1999 to contact local government for assistance.
