Zoo Stock Species and the Red List
Zoo Stock Species and the Red List
Zoo Stock
This indicates that the species is included in the Second Zoo Stock Plan, which was formulated by the Tokyo Metropolitan Government in 2018. The plan sets goals for the next 10 years in three areas: "species conservation," "contribution to wildlife conservation," and "environmental education and conservation awareness." 124 animal species are included.
What is the Red List?
Based on scientific research, this is a list of wildlife classified by rank (category) indicating the degree of risk of extinction.
Livng Things Encyclopedia shows the categories (mainland and islands) assessed by the IUCN (International Union for Conservation of Nature) at the global level, the Ministry of the Environment for Japan, and the Tokyo Metropolitan Government for Tokyo.
The higher the category in each table, the higher the risk of extinction, and CR, EN, and VU are the three categories known as "endangered species." In Tokyo, species that are not at the NT (near threatened) level but are relatively rare are considered "species of concern."

Wild Boar
Sus scrofa
Wild Boar
Sus scrofa
They use their sensitive noses to sniff the ground, searching for small creatures such as plant roots, earthworms, and insects. They have strong, sturdy muscles around their necks, making them strong enough to push up rocks and fallen logs weighing the same as their own body weight. Females give birth to around four to five babies in the spring. For about six months after birth, the babies have a striped appearance that makes them easily blend into the forest scenery.
