In the succession of plant communities, this refers to the invasion and establishment of a place where no seeds or spores exist. This refers to the succession on islands immediately after they are formed by the eruption of an undersea volcano, or in places where lava flows have cooled and solidified. Unlike secondary succession in places where part of the existing vegetation has been lost, it takes a long time to reach the climax stage.

植物群落の遷移において、種子や胞子などがまったく存在しない場所に侵入・定着すること。海底火山の噴火によって形成された直後の島や、溶岩流が冷えて固まった場所での遷移を指す。既存植生の一部が失われてできた場所への二次遷移と異なり、極相に至るまで長い時間を必要とする。
