The relationships between the present distribution of native Fuegian vascular
plants and their ecological behaviour have been studied on the basis of information and multivariate analysis. 216 species (54 % of the total flora) were collected during two surveys within a transect across the main vegetation zones of Isla Grande de Tierra del Fuego; the ecological and phytogeographic informations are derived from field and literature data. The results show that: 1) the species list obtained by the survey along the transect have the same informational content of the total flora of lsla Grande; 2) seven out of twelve species groups obtained by numerical classification of phytogeographic data are well correlateci to the main habitat-types of Fuegia, i.e. steppe, forest and bog communities; 3) the Andean Cordilleras played the main role in plant migration to Fuegia after the ice retreat.
