Save Madagascar’s Fragile Ecosystems From Invasive Species

Target: Niklas Hagelberg, Coordinator of the Ecosystem Management Subprogram at UN Environment

Goal: Eradicate a dangerous invasive toad that threatens Madagascar’s native species.

Approximately 70 percent of Madagascar’s plant and animal species are found nowhere else on earth. Many of these species are now threatened by a toxic invader: the Asian toad. This invasive toad secretes a toxin that is deadly to native birds, mammals, and snakes as well as posing significant threats to human health.

The Asian toad is thought to have arrived in Madagascar between 2007 and 2010 and its population has been expanding rapidly ever since. If left unchecked, it will wreak havoc on all levels of the food chain. Asian toads, which grow up to 8 inches, prey on Madagascar’s vulnerable small mammals, snakes, and amphibians. The toads could spread deadly diseases to Madagascar’s already-threatened native amphibian population and poison native predators that try to eat them. Asian toads also threaten human health – their carcasses contaminate wells and waterways and they are toxic enough to kill a child.

It is imperative that these toads are eradicated as soon as possible to protect the dozens of endangered species that make their home in Madagascar. Sign this petition to urge UN Environment to provide funds to eliminate this dangerous species before Madagascar’s ecosystems are destroyed.


Dear Mr. Hagelberg,

Madagascar is home to over 250,000 plant and animal species, the majority of which are found nowhere else on earth. But Madagascar’s ecosystems are being threatened by the Asian toad, a dangerous invasive species. The toad secretes a potent toxin, which makes it dangerous to Madagascar’s native predatory birds, snakes, and mammals. The toad also spreads diseases to other amphibians, threatening Madagascar’s 300 native frog species. These toxic toads contaminate water sources and can sicken and even kill children. To protect the animals and people of Madagascar, it is critical that these toads be eliminated from the island.

Invasive species experts have established strategies to eradicate this toad from Madagascar, but lack the funds to complete the project. I ask that you do all you can to work with your colleagues in the Ecosystem Management Program at UN Environment to obtain the necessary funds to eradicate the Asian toad and protect Madagascar’s fragile ecosystems.
