Reviewing the transition of conservation education in high school biology, I researched descriptions in high school biology textbooks from 1948 to 2008. The following results were obtained:1. An emphasis on the descriptions of conservation of living things has changed, consistent with enacted laws concerning protection of nature, from protection of living things as resources, protection of natural monuments, conservation of ecosystems, to conservation of biodiversity.2. Descriptions of the decrease of habitat and the effects on native species of alien species were found. However, the reason why genetic diversity was reduced was not explained, and the reason for the change of environmental quality was also not explained.3. The living things which needed conservation were changed from ones on the natural monuments list to those on the endangered species list. Some text books describe a factor to reach extinction. What is desired is an explanation of what situation biodiversity is in and the reason why biodiversity was reduced. And it is hoped hereafter to teach not only ecosystem diversity and species diversity but also genetic diversity by showing examples around us.
