Description
Corvo is a small and remote island in the western group of the archipelago of Azores, Portugal. Lichen diversity has been studied in the Azores archipelago since 1844 but only 16 species are known from Corvo Island so far. This study reports 69 new records of lichen species on Corvo island, representing an addition of two classes, eight orders, 18 families and 43 genera. It includes three new records for the Azores: Acrocordia conoidea (Fr.) Körb., Chrysothrix flavovirens Tønsberg and Glaucomaria rupicola (L.) P.F. Cannon (syn. Lecanora rupicola (L.) Zahlbr.). Additionally, it confirms the presence of three species previously reported in the archipelago without specific locations: Lecidea phaeops Nyl., Peltigera canina (L.) Willd. and Pertusaria ficorum Zahlbr. This wealth of new lichen species records greatly enriches our understanding of biodiversity and sets a solid groundwork for upcoming ecological investigations in the Azores archipelago.
Data Records
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 40 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

| Study Area Description | Corvo is the northernmost, the smallest (17 km²) and the least populated island (384 people) in the Azores archipelago. The only urban centre, Vila do Corvo, is located on the southern tip of the island, roughly at sea level. The areas surrounding the village and extending through the eastern coast are mostly dedicated to agriculture while areas to the north of the village are mostly used as pastureland for dairy cattle. The north part of the island is dominated by the caldera of the volcano reaching 720 m in altitude and with several small lakes and islets at the bottom. The caldera slopes are covered in mixed vegetation and no native laurel forests remain. |
| Design Description | The collection of specimens was performed “ad hoc” in different locations and from different substrates on Corvo Island. |
Sampling Methods
Samples were collected "ad hoc", from different substrates and locations in Corvo island. The most common substrate were basalt rocks and basalt walls, followed by Metrosideros excelsa trees.
| Study Extent | Samples were collected "ad hoc" by AFR, at eight locations in Corvo Island, ranging from 5 m to 560 m in altitude. Most specimens were collected in Vila Nova do Corvo and Miradouro do Caldeirão. The collections took place on two visits to Corvo Island, in June 2009 and September 2023. |
|---|---|
| Quality Control | Specimens were examined by two scientists with a strong lichenological background. Taxonomy and distribution data was sourced from multiple reliable sources. |
Method step description:
- All specimens were thoroughly examined using conventional techniques in the field that allowed identification to the species level. Expert identification by a lichen taxonomist allowed the accurate determination of the less common species based either on detailed photography of the specimens or on collected samples. The species nomenclature follows Index Fungorum (https://www.indexfungorum.org), Mycobank (https://www.mycobank.org/) or recently published literature (e.g. several chapters of Lichens of Great Britain and Ireland 3rd edition (https://britishlichensociety.org.uk/identification/lgbi3)). Distribution data was sourced from multiple reliable sources, including the checklist of the Azores (Aptroot et al. 2010) and the AZORESBIOPORTAL (https://azoresbioportal.uac.pt/).
