Sociation
(also microassociation), a taxonomic unit of vegetation distinguished by the dominant forms of the principal strata of the vegetational cover. A sociation is smaller than an association (seeASSOCIATION, PLANT). The following sociations are distinguished in an association of a pine forest with a ground cover of lichens: pine groves with a ground cover of the lichen Cladonia alpestris and pine groves with a cover of the lichens C. silvatica and C. rangiferina. The term “sociation” was introduced in 1930 by the Swedish geobotanist G. Du Rietz. Want to thank TFD for its existence?
