Description
This study was conducted between 2012 and 2013 to analyze the biodiversity of woody plants across three oceanic islands (Terceira, Tenerife, and Réunion) with distinct geographical characteristics. The research aimed to investigate patterns of variation in the structure of the vegetative community within the native forests of each island. A standardized methodology was applied across the three islands, focusing on native forests that were little anthropogenic disturbance. Ten plots (50 m × 50 m) were established on each island, within which a 5 m × 5 m square was demarcated (see Borges et al., 2018a). The study generated 30 event records and 402 occurrence records

Données sur le projet
The aim of this study was to investigate the patterns of variation in the diversity of woody plants across three oceanic islands, which are representative of different geographical regions: Terceira Island (temperate climate - Azores), Tenerife Island (subtropical climate - Canary Islands), and Reunion Island (tropical climate - Mascarene). Comparable methodologies were employed on all three islands to examine patterns in community structure.

| Description du domaine d'étude / de recherche | This study was conducted in native, humid forest ecosystems with minimal anthropogenic influence across three oceanic islands of volcanic origin: Terceira, Tenerife, and Reunion. Terceira Island is located in the Atlantic Ocean, Central Group of the Azores archipelago, lies at 38° 43′ 0″ N and 27° 12′ 0″ W. The island spans about 29 km in length and 18 km in width, with a perimeter of 90 km, covering an area of approximately 402.2 km². Its highest point, located in the Santa Bárbara mountain range on the western side, reaches an elevation of 1021 m a.s.l. above sea level (Forjaz 2004). The island is characterized by high relative humidity and mild temperatures with minimal seasonal fluctuations (Azevedo 2001). In the Santa Bárbara Mountain, the average annual rainfall exceeds 3400 mm, and the mean temperature is 9°C (Azevedo et al. 2004). Tenerife Island is located in the Atlantic Ocean on the northwest coast of Africa, at 28.28° N, 16.15° W, and is the largest island in the Canary Islands archipelago. The island's climate is influenced by the northeast trade winds, which generate a cloud layer over the northern part of the island. This results in a climatic contrast, with the northern areas being more humid and temperate, while the southern regions are characterized by hotter and more arid conditions. At the island's center lies the plateau of the Las Cañadas volcanic caldera, situated at an altitude of approximately 2000 m a.s.l. above sea level, with Mount Teide summit reaching 3718 m a.s.l. above sea level (Fernández-Palacios 1992). Reunion Island is part of the Mascarene archipelago, situated in the Indian Ocean (21°06'31.2012" S; 55°31'34.1904" E), approximately 800km East of Madagascar. It experiences a humid tropical climate characterized by two relatively distinct seasons (Réchou et al. 2019). The hot and rainy season (summer), influenced by cyclonic resulting in intense rainfall, and cooler and relatively drier season (winter). Temperatures are moderate, with the average maximum temperature along the coast reaching 32.4°C during summer and the minimum in winter around 16°C. Temperature decreases with altitude, and the higher regions of the island (above 1800–2000 m a.s.l. above sea level) are prone to frequent night frosts (Badré and Cadet 1978; Réchou et al. 2019). The average annual rainfall shows a significant dissymmetry between eastern and western sides of the Island due to the topography and high elevation (Réchou et al. 2019), reaching 3070 m a.s.l. above sea level (Thébaud et al. 2009). The zones on the three islands were selected based on their vegetative composition, which was predominantly comprised of endemic and native species from humid and relatively undisturbed forests. The study sites were essentially pristine on two of the islands (Terceira and Reunion), while on Tenerife, the sites consisted of a mix of pristine and historically anthropogenically altered forests. The dominant species Terceira included Juniperus brevifolia (Hochst. ex Seub.) Antoine subsp. brevifolia, Laurus azorica (Seub.) Franco, Myrsine retusa Aiton, Vaccinium cylindraceum Sm.; on Tenerife, they were Erica canariensis Rivas-Mart., M. Osorio & Wildpret, Erica platycodon (Webb & Berthel.) Rivas-Mart. & al., Laurus novocanariensis Rivas-Mart., Lousa, Fern. Prieto, E. Días, J.C. Costa & C. Aguiar, Morella faya (Aiton) Wilbur, Prunus lusitanica L.; and on Reunion, they wereDanais fragrans (Lam.) Pers., Gaertnera vaginata Poir., Molinaea alternifolia Willd., and Phyllanthus phillyreifolius Poir. (Borges et al., 2018b). |
| Description du design | This study constitutes an inventory of woody plant species in native forests across three geographically distinct oceanic islands: Terceira Island (Atlantic Ocean), Tenerife Island (Atlantic Ocean), and Réunion Island (Indian Ocean). The research was conducted in 2012 and 2013 with the aim of investigating patterns in the taxonomic diversity of woody plants on these islands. A standardized protocol was employed to identify the tree species present in ten 50 m × 50 m plots within native forests on each island (Borges et al. 2018a; 2018b). |

Méthodes d'échantillonnage
In each plot, a 5 m × 5 m square was demarcated at each corner for a specific plant survey. Within each corner subplot (5 m × 5 m), all woody species with a diameter at breast height (DBH) ≥ 1 cm were counted, and the results were expressed as the total number of shoots per species per 100 m². In Reunion, due to the high local alpha diversity, 20 square plots measuring 5 m × 5 m were surveyed (ten along the upper limit and ten along the lower limit of the quadrat) to inventory woody plants with DBH ≥ 1 cm, instead of the four 5 m × 5 m plots at each plot corner (see Borges et al. 2018a).
| Etendue de l'étude | This study established ten 50 m × 50 m square plots on each island, maximizing the distance between plots within the same mountain range or continuous forest patch. |

| Contrôle qualité | All specimens were identified by taxonomic experts |
