Mapping Vascular Plant Diversity on São Jorge Island under the PRIBES project

The island is a narrow volcanic ridge approximately 55–56 km long and 6.5–8 km wide, with an area of about 237–246 km². Its highest elevation is Pico da Esperança (1,053 m a.s.l.) (Madeira & Brum da Silveira, 2003).

A total of 243 vascular plant taxa were recorded across São Jorge Island, encompassing 8 classes, 40 orders, and 89 families. These records correspond to 4,523 individual plant occurrences, including repeated observations of the same species across different sites. As each photographic observation is tied to unique geographic coordinates, all recorded specimens represent new spatial records for the island’s flora.
