Introduction to Grant Projects

Animal-pathway & Wildlife Association (ApWA)

Animal-pathway's nationwide outreach

Activity grant

Project Description

In Japan, the total length of roads is around 1,270,000km, and around 120,000km for railroads. Both of these are essential for our daily lives, but the proportion of forest land is around 68% and the extension of roads that divide forests is extensive. Arboreal animals living in these divided, isolated forests can no longer go back and forth, which causes genetic deterioration and regional extinction. Our organization is spreading the availability of migration pathways on roads, "animal pathways" and are helping environmental education by using books and images of the species using these pathways.

Establishment purpose
To protect wild arboreal animals that we are not familiar with, including Japanese squirrels, Japanese dormouse, giant flying squirrels, and flying squirrels by developing an artificial route, an inexpensive animal pathway, on the roads between divided forest areas. As a result, we collaborate with local governments, road administrators, architectural consultants and user corporations to educate children and the next-generation community.
