Abstract. The identification of priority areas for the conservation of Brazilian biodiversity and the application of prompt practical measures are essential for an effective environmental management. The Serra do Rola Moça State Park, located in the Iron Quadrangle, on the southern end of the Espinhaço Range, in Minas Gerais, Brazil, is a region that is home to the rupestrian ferruginous fields or canga vegetation, a still poorly studied vegetation, rich in endemic, rare, and endangered species. The aim of this work is to contribute to the understanding of the rupestrian ferruginous fields, providing a floristic analysis, a quantification of species richness, and survival (vegetative growth in laboratory conditions, the production of nursery saplings and the management of the areas) of translocated species from the Capão Xavier mine pit to the park. The species presented belong mainly to the Asteraceae, Rubiaceae, Myrtaceae, Velloziaceae, Bromeliaceae, Orchidaceae, and Solanaceae families. Nowadays, the surrounding area of the administrative headquarters of the park shelters around 10 000 individuals and about 15 000 in other areas of the park. In the rescue and transposition of saplings, there was a loss of less than 31.29 % of the individuals directly introduced to the planting area, while only 10 % of the saplings grown in the nursery were lost. The knowledge acquired about the viability of the studied species, their spread, and conservation indicates the possibility of nursery breeding of some of the native species and their use in the recovery of areas in mining regions.

A região central do estado de Minas Gerais, especificamente o Quadrilátero Ferrífero e a Serra do Espinhaço Meridional, é marcada pela ocupação em busca de riquezas minerais tais como diamante e ouro. Possui, ainda, relevância ecológica, o que levou a declaração desta região, pela Unesco em 2005, como Reserva da Biosfera da Serra do Espinhaço. Vislumbrou-se, nesse artigo, a caracterização e análise de processos de degradação ambiental em literatura de viagem de naturalistas estrangeiros que percorreram esta região no século XIX. Trabalhos de campo ocorreram em roteiros estabelecidos a partir da leitura das obras, com enfoque no entendimento da paisagem. Evidências de degradação ambiental pelo extrativismo mineral do ouro e diamante, apresentadas nas narrativas em áreas dos caminhos da Estrada Real, caracterizam-se pela supressão da vegetação nativa por meio de queimadas, mudança/desvio de cursos fluviais, uso de mercúrio para beneficiamento mineral além de ocorrência significativa de espécimes monotípicas invasoras, como o capim-gordura e a samambaia. O estudo, pela descrição analítica em relatos de naturalistas viajantes analisados no território da reserva da biosfera, permite um resgate memorial que vincula o ser humano à natureza, como parte de sua história ambiental.Palavras-chave: relatos de viajantes, mineração, mercúrio, queimadas, capim-gordura.AbstractThe central region of Minas Gerais state, specifically the Iron Quadrangle and the Southern Espinhaço Range, has a unique occupation history due to mineral riches such as diamond and gold. Furthermore, it has significant ecological relevance, which has led to the declaration of the Espinhaço Range Biosphere Reserve by Unesco in 2005. To characterise and analyse the historical processes of environmental degradation of this region, the travel literature of foreign naturalists who travelled throughout the region in the 19th century was investigated. The research involved studying scripts produced from reading works, with a focus on the understanding of the landscape. Evidence of environmental degradation by gold and diamond extractivism is presented in several areas of the Estrada Real, characterised by the suppression of native vegetation by anthropic burning, change of river courses and use of mercury for mineral processing, in addition to a significant occurrence of invasive monotypic species, such as molasses grass and fern. From the analytical description in reports of travelling naturalists, the analysis of the reserve territory of the present study allows the recovery of part of a memory that binds human to nature as part of its environmental history.Keywords: travellers’ accounts, mining, mercury, burning, molasses grass.

Abstract—We describe and illustrate Paepalanthus fabianeae, a new species of Eriocaulaceae from the central portion of the Espinhaço Range in Minas Gerais, Brazil. Previous phylogenetic evidence based on analyses of nuclear (ITS and ETS) and plastid (trnL-trnF and psba-trnH) sequences revealed P. fabianeae as belonging to a strongly supported and morphologically coherent clade containing five other species, all of them microendemic, restricted to the Espinhaço range. Due to the infrageneric classification of Paepalanthus being highly artificial, we preferred not assigning P. fabianeae to any infrageneric group. Paepalanthus fabianeae is known from two populations growing in campos rupestres (highland rocky fields) in the meridional Espinhaço Range. The species is characterized by pseudodichotomously branched stems, small, linear, recurved, and reflexed leaves, urceolate capitula, and bifid stigmas. Illustrations, photos, the phylogenetic position, and a detailed description, as well as comments on habitat, morphology, and affinities with similar species are provided. The restricted area of occurrence allied with threats to the quality of the habitat, mainly due to quartzite mining, justifies the preliminary classification of the new species in the Critically Endangered (CR) category using the guidelines and criteria of the IUCN Red List.
