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."

What corner is it now?
The horns fall off from the base every spring. New horns covered with brown skin soon begin to grow, and by summer they are fully grown. Towards the end of summer, the brown skin peels off, revealing the white, bony horns. Be sure to record what kind of horns you had that day, along with the date.
What color is your hair now?
Their fur color changes with the seasons. From spring to summer, their bodies are light brown with white spots. From autumn to winter, their entire body is a dull dark brown. These colors allow them to blend into the forest scenery in each season and make them less noticeable to predators.
