Study Extent

The PESC covers the municipalities of Barra do Piraí and Valença, in the state of Rio de Janeiro, Brazil. Coordinates: 22°23'59"S and 22°17'22"S Latitude; 43°40'30"W and 43°53'07"W Longitude.

Sampling

The list of all vascular plant specimens from the PESC was obtained through four searches in four online national databases: JABOT RB and JABOT Geral, Herbário Virtual REFLORA, and speciesLink. An initial search was conducted using the filters "Concórdia" and "Santa Mariana" for "locality", which returned 234 unique records. Due to the limited number of initial records, the municipalities names ("Barra do Piraí" and "Valença") were included in the filters used. The following filters for location were applied: (1) "Barra do Piraí", (2) "Valença", (3) "Concórdia", and (4) "Santa Mariana". These searches resulted in a total of 13,672 records (JABOT RB = 1,291; JABOT Geral = 2,416; REFLORA = 3,348; and SpeciesLink = 6,617. The specimens identified to species were separated by manually, resulting in: JABOT RB = 998 (undetermined = 293), JABOT Geral = 1,925 (undetermined = 491), REFLORA = 2,790 (undetermined = 558), and speciesLink = 5,565 (undetermined = 1,052). Records with a locality outside the PESC area and another specific locality within (e.g. "Fazenda Santa Mônica", "Parque Natural Municipal do Açude da Concórdia", "Curral de Santa Mariana", "Cachoeira do Bonsucesso", and "Santuário de Vida Silvestre da Serra da Concórdia") were then removed from the list. After this process, the duplicates were removed, resulting in 339 records, which were filtered to retain one record for each species, prioritizing those with images in the databases. The raw data was subdivided into Microsoft Excel sheets, with determined (one record by name species), and undetermined records.

Quality Control

A preliminary list of 339 specimens was checked and validated by 24 taxonomists, using images available in herbaria and their online databases.

Method steps

1. The dataset initially contained 13,672 records downloaded from Jabot, SpeciesLink, and Reflora. These records underwent a series of filtering steps: first, records determined at the species level were selected, reducing the number to 11,278. Next, records collected within the Parque Estadual da Serra da Concórdia (PESC) were identified, narrowing the count to 1,710. After removing duplicates, 339 records remained. These were then sent for taxonomist review, resulting in 235 records. Finally, after taxonomists revised the species, 231 species were confirmed for inclusion.
