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."

Przewalski's Horse
Equus przewalskii
Przewalski's Horse
Equus przewalskii
They live in groups (harems) consisting of one male and several females. Each female in a harem has a leader, and the other members of the group also have a set hierarchy. Males that are not part of a harem form groups with other males. They once inhabited a wide area from Mongolia to Europe, but became extinct in the wild in the late 1960s. Currently, reintroduced groups live in the Gobi Desert and Hustai National Park in Mongolia.

Body color
Domestic horses come in a variety of colors, but all Przewalski's Horse 's horses are nearly identical in color. Their bodies are brown, their feet are black, and their bellies and noses are whitish. Their manes are short and upright. They have dark brown stripes (eel stripes) along their backs.
reintroduction into the wild
They became extinct in the wild in the late 1960s, but conservation projects using captive specimens in Europe and the United States led to their successful breeding, and in 1992 they were reintroduced to protected areas in Mongolia.
