Caatinga Flowering Plant Diversity from Floristic and Phytosociological Studies

Based on 112 peer-reviewed studies published up to December 2020, this dataset compiles information on species distribution in the Caatinga biome of Brazil. It includes a conservative estimate of 1,775 taxa identified at the species level, with a total estimated richness of 2,978 species, and organizes data on growth form, IUCN conservation status, and distribution across biogeographic districts and Holdridge life zones. The data are derived from 131 surveyed areas and are intended to inform local conservation policies and biodiversity assessments.

Use Cases

• Assessing species conservation status based on IUCN classifications and growth form data.
• Analyzing plant species distribution across Neotropical biomes, biogeographic districts, and Holdridge life zones.
• Identifying species-rich families and endemic or threatened species for targeted conservation planning.
• Mapping surveyed areas for spatial analysis using provided area codes and metadata.

Strengths

• Compiles data from 112 peer-reviewed floristic and phytosociological studies, providing a synthesized view.
• Includes a detailed species list with 1,775 identified taxa and metadata for 131 surveyed areas.
• Annotates species with IUCN conservation status, growth form, and multi-scale geographic distribution.

Limitations

• The exact row count and specific column names are not provided in the available metadata.
• Data is based on literature published up to December 2020 and may not include more recent studies.
• The dataset size (878821) is given without context (e.g., bytes, rows), making scale interpretation difficult.
