Descripción

This study was conducted on São Jorge Island, part of the Central Group of the Azores Archipelago in the North Atlantic Ocean. 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 4,524 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. Among the taxa, 53 are considered endemic to the Azores, 131 are introduced, 58 are native and one species (Dracaena draco) is of indeterminate status. These correspond to 1,774 individual occurrences of endemic taxa, 1779 introduced, 970 native and one with indeterminate status. At the family level, 31 families include endemic taxa, 63 include introduced taxa, 34 include native taxa, and one family contains a taxon of indeterminate status

Datos del proyecto

Despite numerous floristic explorations since the 19th century, detailed, spatially explicit data on plant species occurrence across the varied habitats of São Jorge remain limited. Comprehensive plant inventories are crucial for understanding biogeographical patterns, assessing ecological changes, and guiding conservation strategies. The aim of this study was to develop a spatially explicit inventory of plant species across diverse natural and seminatural areas of São Jorge Island (Azores). Fieldwork was conducted over a seven-day period, from July 13th to July 19th, 2020.

Descripción del área de estudio This study was conducted on São Jorge Island, part of the Central Group of the Azores Archipelago in the North Atlantic Ocean. 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). The island's WNW–ESE orientation results from the alignment of spatter cones along active dextral normal faults, reflecting the tectono-magmatic fabric of the Azores Plateau (Madeira, J., et al., 1998). São Jorge is characterized by steep coastal cliffs—especially along the north coast—rising 400–800 m above sea level, and numerous «Fajãs», flat low-lying areas formed by landslides or lava flows (Zanon & Viveiros, 2019). These unique landforms host a range of habitats, from high-altitude humid forests to coastal zones. The climate is Temperate with mild summer and no dry season (Cfb). These conditions favor dense and persistent vegetation cover and rapid recolonization of disturbed substrates (Zanon & Viveiros, 2019). Although native forests once covered most of the island, they are now restricted to small fragments above 600 m (Elias et al., 2016). Much of the island is currently impacted by exotic and invasive species, particularly in lowland areas and accessible «Fajãs», contributing to ecological challenges and the transformation of native habitats (Silva & Smith, 2004; Borges et al., 2010; Silva et al., 2017, 2018)
Descripción del diseño The aim of the study was to generate a spatially explicit inventory of vascular plant species on São Jorge Island, focusing on natural and semi-natural habitats. Fieldwork was carried out from July 13th to July 19th, 2020. Georeferenced photographs were collected using a Garmin Montana 750i GPS unit, documenting plant diversity across an altitudinal and ecological gradient—from coastal vegetation to high-elevation humid forests, scrublands, and grasslands. Survey areas were selected to avoid highly disturbed habitats such as urban zones, intensive pastures, and exotic tree plantations. Photographs were taken mainly along trails, slopes, cliffs, and road margins. Species visible in the images were identified post-fieldwork by expert taxonomists using floristic guides and online resources. Taxonomic and conservation statuses were assigned based on validated data from the Azores Bioportal – PORBIOTA

Métodos de muestreo

Georeferenced photographs were collected using a Garmin Montana 750i GPS unit, with Multi-GNSS (Global Navigation Satellite System) support and WAAS/EGNOS correction systems that enhance GPS signals with improved accuracy (2-3 m), integrity (error checking) and availability in open-sky conditions. Plant species visible in the images were later identified by expert taxonomists with the help of flora guides (ex. Elias et al. 2024; Schaefer, H. 2021) and online databases (ex. Flora-On Açores; Plant of the World On-line). Species taxonomic ranks and conservation statuses were assigned based on the information available through the Azores Bioportal – PORBIOTA (https://azoresbioportal.uac.pt/pt/), the official biodiversity platform for the Azores Archipelago, which integrates validated and up-to-date data on the region’s flora, including endemism, invasiveness, and habitat preference

Área de Estudio This study was conducted across different areas of the volcanic island of São Jorge (Azores), ranging from coastal areas to high-elevation humid forests, scrublands and grasslands, capturing a variety of habitat types, vegetation density and plant abundance.
Control de Calidad Within each photograph, identified by a unique code, plants were detected.
