Brazilian Botanic Gardens

We argue that botanic gardens, as plant conservation focused institutions, have been tested in temperate regions that possess a relatively robust conservation infrastructure and a relatively low number of threatened species. The ability of the Brazilian botanic gardens to support plant conservation is especially challenging, given their small number relative to Brazil’s plant diversity and the increasing rate of habitat loss and plant endangerment. This study, the first for Brazil, assesses the conservation capacity of Brazilian botanic gardens. An assessment is made of the status of conservation facilities in Brazilian botanic gardens and the conservation status of their plant collections.This was based on a survey sent to thirty-six Brazilian botanic gardens in 2011– 2013 using information from the 2008 Brazilian Red List, and seven state conservation lists. The results identified a small percentage of threatened species (n =102/21 per cent) in ex situ collections of 22 botanic gardens and less than 10 per cent representation for each state red list. An assessment based on the updated Brazilian Red List (2014) showed that 425 threatened species were maintained in living collections of 18 botanic gardens. Despite the extensive size of some collections, the proportion of threatened species in the collections was found to be very low. Improvement in infrastructure, technical capacity, including horticultural skills, and development of policies and protocols will benecessary to increase the effectiveness of the collections for conservation aims

New Brazilian Floristic List Highlights Conservation Challenges

A comprehensive new inventory of Brazilian plants and fungi was published just in time to meet a 2010 Convention on Biological Diversity target and offers important insights into this biodiversity's global significance. Brazil is the home to the world's richest flora (40,989 species; 18,932 endemic) and includes two of the hottest hotspots: Mata Atlantica (19,355 species) and Cerrado (12,669 species). Although the total number of known species is one-third lower than previous estimates, the absolute number of endemic vascular plant species is higher than was previously estimated, and the proportion of endemism (56%) is the highest in the Neotropics. This compilation serves not merely to quantify the scale of the challenge faced in conserving Brazil's unique flora but also serves as a key resource to direct action and monitor progress. Similar efforts by other megadiverse countries are urgently required if the 2020 targets of the Convention on Biological Diversity and the Global Strategy for Plant Conservation are to be attained.Ministerio do Meio AmbienteMinisterio do Meio AmbienteCentro Nacional de Conservacao da FloraCentro Nacional de Conservacao da FloraNational Council for Scientific and Technological DevelopmentNational Council for Scientific and Technological DevelopmentBentham and Moxon TrustBentham and Moxon Trus

Revisitando a flora de Macaé de Cima, Rio de Janeiro, Brasil: o gênero Psidium (Myrtaceae)

Resumo As espécies de Psidium de Macaé de Cima, Rio de Janeiro, Brasil foram revisitadas após pouco mais de 20 anos da publicação do estudo de Myrtaceae para este trecho de Floresta Atlântica, a qual atualmente se constitui em uma Área de Proteção Ambiental. A identificação das espécies foi realizada com base em análise de coleções depositadas em herbário e observação dos indivíduos a campo. Os resultados incluem o tratamento taxonômico, chave de identificação, comentários e registro fotográfico das espécies. O número de espécies de Psidium na área de estudo foi ampliado de três para seis espécies, uma das quais P. ovale representando uma nova ocorrência para o estado do Rio de Janeiro. Os resultados revelaram a necessidade de estudos continuados de flora, especialmente em áreas de alta diversidade, e a sua importância para conservação das espécies e gestão de áreas protegidas

Breve histórico e classificação da vegetação capixaba

Resumo O estado do Espírito Santo apresenta grande variedade de ecossistemas num território relativamente pequeno. A exuberância de suas florestas vem despertando o interesse de muitos naturalistas e viajantes desde o século XIX, os quais deixaram registros valiosos dos primeiros anos da ocupação das "Areas Prohibidas" a leste de Minas Gerais. O cultivo do café, um dos alicerces econômicos do estado, deu início à perda dessas florestas. Tais perdas alavancaram o movimento conservacionista e a pesquisa científica no estado. A biogeografia, riqueza de espécies e de processos ecológicos nos fragmentos que restaram no Espírito Santo ainda revelam surpresas. Dentro do domínio da Floresta Atlântica, o estado abriga diferentes tipos de vegetação: Floresta Ombrófila Densa, Floresta Ombrófila Aberta, Floresta Estacional Semidecidual, Savanas, Formações Pioneiras e Refúgios Ecológicos. A descrição e classificação da vegetação do Espírito Santo ainda está inacabada tendo em vista as incertezas levantadas por alguns estudos. Também não existe um mapa da vegetação que contemple adequadamente a diversificada vegetação. A despeito de tais limitações, apresentamos descrições sucintas sobre os tipos de vegetação que vêm sendo reconhecidos na literatura moderna

Flora of Espírito Santo: Psidium (Myrtaceae)

Abstract This study presents a floristic-taxonomic treatment of Psidium in the state of Espírito Santo, and is a result of fieldwork combined with analyses of herbarium specimens. Fourteen species of the genus were recognized in Espírito Santo state (P. brownianum, P. cattleianum, P. cauliflorum, P. guajava, P. guineense, P. longipetiolatum, P. myrtoides, P. oblongatum, P. oligospermum, P. ovale, P. rhombeum, P. rufum P. sartorianum, and Psidium sp.), accounting for about 34% of the species richness estimated for the genus in the Atlantic Rainforest biome. The species occur predominantly in lowland forests up to 700 meters above sea level. These areas are highly threatened due to urbanization of coastal areas and agricultural expansion in the state Espírito Santo. Therefore, the conservation of Psidium species in this state requires the creation of more lowland protected areas

Species with medicinal and mystical-religious uses in São Francisco do Conde, Bahia, Brazil: a contribution to the selection of species for introduction into the local Unified Health System

We investigated the knowledge and practices of local residents in São Francisco do Conde, Bahia, regarding the use of medicinal and mystical plants with the aim of proposing strategies for the incorporation of phytotherapies into the local Unified Health System through local Basic Health Clinics. This municipality was founded during the early colonization of Brazil, introducing the monoculture of sugarcane and slave labor to the region, resulting in a currently largely Afro-Brazilian population. Key informants and local specialists were interviewed and workshops were undertaken at the Basic Health Clinics to collect data and information. The interviewees made 254 references to 126 plant species distributed among 107 genera and 50 families. Among the species cited with medicinal or mystical uses, 51.6% were considered autochtonous, and 42.8% were cited in at least one document of the Brazilian Health Ministry; of these, 11.1% were mentioned in four to eight documents, indicating potential for introduction to the local Unified Health System. The valorization of local knowledge and practices concerning the use of medicinal plants represents an important approach to public health efforts
