Japan Butterfly Conservation Society (JBCS)

Conserving endangered butterflies

Activity grant

Project Description

A quarter of all Japanese butterfly species are in danger of extinction, but there is currently nothing being done to conserve them. The main factor behind this is the deterioration of their woodland habitats, and there is a need for humans to maintain and manage these living environments. JBCS is an NPO that is assessing the situation of these habitats and carrying out local conservation initiatives. This includes researching the current situation of endangered butterfly species and taking action to conserve them and improve their habitats, as well as raising awareness among local people through lectures and observation tours, collaborating with regional conservation movements, creating pamphlets, and holding symposiums.

Establishment purpose
While the number of endangered butterfly species is increasing, efforts to conserve them are insufficient across Japan, a situation that will lead to further butterfly losses. Also, as butterflies are found in many habitats and are easy to approach, they can act as important bellwethers for conservation efforts across the country. JBCS was established based on this way of thinking and aims to conserve butterfly species on a national level, and encourage the view that butterflies are a symbol of environmental conservation.
