Background: The Parque Estadual do Forno Grande is a fully protected area in the southern Espírito Santo State, Brazil. It belongs to the Atlantic Forest domain, with predominantly dense, ombrophilous, seasonal semi-deciduous forests and herbaceous/shrubby vegetation on rock outcrops. The area is recognised as highly important for conservation, designated as a priority biological area for protecting the Atlantic Forest's biodiversity. Although the importance of Protected Areas in conserving the Atlantic Forest biodiversity is unquestionable, it is crucial to understand the floristic patterns within these regions to develop effective conservation strategies. We utilised national online databases to compile species lists containing relevant information about their biodiversity. The updated list of vascular plants recorded in the Parque Estadual do Forno Grande is available in the "Catálogo de Plantas das Unidades de Conservação do Brasil" and it is presented here with further information on richness, endemism and conservation status., New Information: The Parque Estadual do Forno Grande harbours 958 species of vascular plants, of which 79.2% are angiosperms, 18.4% are ferns and 2.4% are lycophytes. Amongst these species, 44% are endemic to the Atlantic Forest. There are 58 threatened species, of which six are Critically Endangered, 39 are Endangered and 13 are Vulnerable. Amongst the threatened species, 51 are endemic to the Atlantic Forest. The number of records and the species richness in this area are notably high for Atlantic Forest standards. Our findings suggest that floristic inventories of Brazilian Protected Areas are a key contribution to the general perception of how much we still do not know about our flora. It also highlights the necessity of supporting floristic surveys in poorly-known areas, especially those remaining as forest remnants., (Thuane Bochorny, Guilherme M. Antar, Igor H.F.

Background: The Atlantic Forest is one of the most diverse and threatened phytogeographical domains in the world. Despite that, it includes regions with poor floristic knowledge, even in protected areas. Although the importance of protected areas in conserving the Atlantic Forest hotspot is undisputed, it is necessary to recognise the floristic richness of these areas to propose effective conservation actions. In this sense, online databases have proved to be a promising tool for compiling species lists with relevant biodiversity information. This study is based on the list of vascular plants of the "Parque Estadual da Pedra Selada", published in the "Catálogo de Plantas das Unidades de Conservação do Brasil". It summarises the species richness, endemism and conservation status of this protected area., New Information: The published list of vascular plants was based on data obtained from herbarium collections available in online databases. A total of 303 species have been recorded for the "Parque Estadual da Pedra Selada," of which 297 are native to Brazil, 78 are endemic to the Brazilian Atlantic Forest, and seven are endemic to the State of Rio de Janeiro. More than 60% of the species are woody, and more than 40% are trees. Eight threatened species (Endangered - EN and Vulnerable - VU), of which five are endemic to the State of Rio de Janeiro, are housed in this protected area. One species was classified as Data Deficient (DD). Our results increase the knowledge of the Atlantic Forest flora in the State of Rio de Janeiro and support effective conservation planning for this protected area., (Isabela Maciel Waga, Andrea Ferreira da Costa, Claudine Massi Mynssen, Eduardo Pinheiro Fernandez, Elsie Franklin Guimarães, Fernanda Saleme, George Azevedo de Queiroz, Guilherme Medeiros Antar, Haroldo Cavalcante de Lima, Hemily Oliveira Marques, Lara Serpa Jaegge Deccache, Leandro Jorge Telles Cardoso, Leandro Lacerda Giacomin, Maria Regina de V. de Vasconcellos Barbosa, Mario Gomes, Marli Pires Morim, Otávio Luis Marques da Silva, Pedro Fiaschi, Pedro Luís Rodrigues de Moraes, Rafaela Campostrini Forzza, Renon Santos Andrade, Thaís Andrade Ferreira Dória, Thiago Serrano de Almeida Penedo, Thuane Bochorny, Marcio Verdi.)

Background: The Atlantic Forest is one of the most threatened biomes in the world. Despite that, this biome still includes many areas that are poorly known floristically, including several protected areas, such as the "Floresta Nacional do Rio Preto" ("Flona do Rio Preto"), located in the Brazilian State of Espírito Santo. This study used a published vascular plant species list for this protected area from the "Catálogo de Plantas das Unidades de Conservação do Brasil" as the basis to synthesise the species richness, endemism, conservation and new species occurrences found in the "Flona do Rio Preto"., New Information: The published list of vascular plants was based on field expeditions conducted between 2018 and 2020 and data obtained from herbarium collections available in online databases. Overall, 722 species were documented for the "Flona do Rio Preto", 711 of which are native to Brazil and 349 are endemic to the Atlantic Forest. In addition, 60 species are geographically disjunct between the Atlantic and the Amazon Forests. Most of the documented species are woody and more than 50% of these are trees. Twenty-three species are threatened (CR, EN and VU), while five are Data Deficient (DD). Thirty-two species are new records for the State of Espírito Santo. Our results expand the knowledge of the flora of the Atlantic Forest and provide support for the development of new conservation policies for this protected area., (Anderson Alves-Araújo, Marina M Moreira, Tatiana T Carrijo, Lúcia G Lohmann, Adriana Q Lobão, Alana F Scheidegger, Aline D Firmino, Aline Vieira de Melo Silva, Álvaro Nepomuceno, Amélia C Tuler, André MA Amorim, André LC Moreira, Braz AP Cosenza, Brenno G Sossai, Christian Silva, Claudia R Lopes, Daniele Monteiro, Dayvid R Couto, Duane F Lima, Eduardo C Dalcin, Eliana Ramos, Elton J Lírio, Fatima Salimena, Felipe Alves de Oliveira, Fernanda RM Fraga, Filipe Torres-Leite, Guilherme M Antar, Gustavo H Shimizu, Haroldo C Lima, Herison Medeiros, Jaquelini Luber, Jheniffer A Christ, João Lanna, João Paulo F Zorzanelli, Joelcio Freitas, José FB Pastore, José IM Melo, Juliana Paula-Souza, Juliana RPM Oliveira, Leandro C Pederneiras, Leandro Freitas, Leandro L Giacomin, Leonardo D Meireles, Luis AE Silva, Luiz JS Pinto, Luiz Menini Neto, Marcelo Trovó, Mário L Garbin, Marli P Morim, Michel Ribeiro, Nelson TL Pena, Paulo H Labiak, Pedro H Cardoso, Pedro L Viana, Pedro LR Moraes, Quélita S Moraes, Raquel F Zorzanelli, Renara N Amaral, Renata C Asprino, Renato Goldenberg, Ricardo Magnago, Ricardo S Couto, Sandrine C Dutra, Saúl E Hoyos-Gómez, Tamara AF Vieira, Thiago B Flores, Valquíria F Dutra, Víctor S Miranda, Vitor C Manhães, Rafaela C Forzza.)

Background: Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of "Parque Nacional do Caparaó" (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states., New Information: "Parque Nacional do Caparaó" houses 8% of the land plant species endemic to the Brazilian Atlantic Forest, including 6% of its angiosperms, 31% of its lycophytes and ferns and 14% of its avascular plants. Twelve percent of the threatened species listed for the State of Espírito Santo and 7% listed for the State of Minas Gerais are also protected by PNC. Surprisingly, 79% of the collections analysed here were carried out in Minas Gerais, which represents just 21% of the total extension of the Park. The compiled data uncover a huge botanical collection gap in this federally-protected area., (Marina M Moreira, Tatiana T Carrijo, Anderson G Alves-Araújo, Alessandro Rapini, Alexandre Salino, Aline D Firmino, Aline P Chagas, Ana F A Versiane, André M A Amorim, Andrews V S da Silva, Amélia C Tuler, Ariane L Peixoto, Bethina S Soares, Braz A P Cosenza, Camila N Delgado, Claudia R Lopes, Christian Silva, Daniel E F Barbosa, Daniele Monteiro, Danilo Marques, Dayvid R Couto, Diego R Gonzaga, Eduardo Dalcin, Elton John de Lirio, Fabrício S Meyer, Fátima R G Salimena, Felipe A.
