Abstract Grasses are one of the most successful and dispersed plant families worldwide their environmental economic values widely acknowledged. They dominate landscape Cabo Verde, southernmost driest archipelago Macaronesia, relevant natural resources for local populations, but a comprehensive evaluation distribution patterns is still lacking. In this study, we aim to evaluate potential effects climate change using long‐term data concerning grass in Verde recognized climatic variability archipelago, which entails huge irregularity spatial temporal rainfall. We identified two contrasting periods (wet, from 1929 1968, dry, 1969 2007) gathered all information available bibliography, herbaria, fieldwork spontaneous species recorded during those periods, amounted 107 taxa. This was then used disclose diversity as related topographic variables (altitude windward vs. leeward aspects). Different altitudinal shifts assemblages an assemblage specific wet period were revealed by comparing periods. The role exposure delimiting various highlighted; trade winds clearly determine assemblages. detected according (related macroclimate) factors (associated with mesoclimates). Also, functional traits (i.e., annuals perennials, C3 C4 grasses, tropical temperate species) found vary between dry well altitude slope aspect. Understanding distributions crucial predicting how will affect them thus support effective management conservation actions.
