catalogoUCsBR: A new R package and application for creating comprehensive plant species lists for Brazilian Protected Areas.

Premise: The increased online publication of data associated with Brazilian botanical collections and biodiversity information systems has significantly improved access to information on plant species occurring in Brazil. However, information about Brazilian flora within Protected Areas is fragmented. Methods and Results: The catalogoUCsBR package-developed in R and as a Shiny application-performs several data refinement processes to facilitate creating comprehensive plant checklists of Brazilian Protected Areas. Functions include combining herbarium records into a desired format and removing duplicates from different databases, extracting information on accepted species names, facilitating taxonomic revision through digitized images and labels from herbarium collections, and publishing the plant species list in the Catálogo de Plantas das Unidades de Conservação do Brasil. Conclusions: The catalogoUCsBR package is an open platform designed for creating taxonomically verified plant species lists that enhances the effectiveness of Brazilian conservation efforts, ensuring that they are based on accurate and up-to-date biodiversity information.
