Plant diversity in sub-Antarctic ecosystems is currently threatened by land use, forest management, cattle grazing, species invasion and climate change. Based on 535 floristic inventories (richness, cover), including 230 vascular plants species distributed in Tierra del Fuego, we assessed plant distribution at stand, landscape and regional scales. We developed habitat suitability maps for 35 vascular plants using environmental niche factor analysis and a set of 14 environmental predictor variables. Maps were combined into an overall plant diversity conservation map. Appropriate management actions including a targeted network of protected areas should be established for conserving plant diversity.
