Protection of endangered species and measures against alien species

Amamioshima has been chosen as a candidate site for World Natural Heritage designation. However, there are measures that need to be taken, including the protection of endangered species. Many of these issues can be solved by upgrading the thoughtfulness of individuals and observing public manners.

Protection of endangered species

Prevention of animals from being killed on the roads

Roadkill prevention signboards have been installed in order to protect Amami rabbits and other endangered species from being killed in traffic accidents. We encourage drivers to drive slowly especially when driving on mountain roads at night.

Prevention of adverse effect of goats

Goats that have returned to the wild have caused damage to endangered wild species of flora and fauna. The destruction of vegetation has caused landslides and other damage. Since it is important to protect ecologically sensitive areas from such adverse effects, capturing feral goats is one of the measures now being taken towards designation as a World Natural Heritage Site.

Protective measures for sea turtles

Sea turtles are an integral part of the rich natural environment. Because of its academic and cultural values to local governments and citizens, collaborative investigation and studies of suitable protective measures is underway with the goal of ensuring that sea turtles are inherited to future generations.

Conservation of coral reefs

Coral reefs closely interact with other living creatures and thus help form a diverse ecosystem. They are precious assets to both nature and to the well being of communities. For these communities, reefs can be used as a tourism resource or they can function as wave breakers.
In order to protect these coral reefs, extermination of crown-of-thorns starfish Acanthaster planci is being conducted and investigation of and research on the nature of coral is being carried out.

Measures against alien species

Various alien species that have invaded Amamioshima have had adverse effects on the original ecosystem of Amamioshima. Especially predation of native species by mongoose and feral cats and other alien species has caused a problem that will require taking measures against these intruders in order to stop and reverse the effect on endangered wild flora and fauna.

Measures to be taken against mongoose

In 1979, approximately 30 mongoose individuals were released to Amamioshima as a measure against Habu Trimeresurus flavovirdis snakes and against rats. Later it was found that mongoose predate precious native animals.
Therefore, in order to recover the ecosystem, the capturing of mongoose and the investigation of the recovery status of the native animals that had been reduced in number by mongoose have been undertaken.
