“…The importance of herbs, especially monocots, to the floral composition of inselbergs is observed in other studies (Oliveira & Godoy 2007;Gomes & Sobral-Leite 2013). In this study, monocots were responsible for harboring 56% of species and 27% of families recorded for the area, indicating the importance of this group for the vegetation of inselberg, though very often neglected in restoration of areas mined for ornamental stones.…”

Our study on granitic and gneissic rock outcrops on Pedra dos Pontões in Espírito Santo state contributes to the knowledge of the vascular flora of inselbergs in southeastern Brazil. We registered 211 species distributed among 51 families and 130 genera. Orchidaceae, Bromeliaceae and Polypodiaceae were the most representative families. Concerning vegetative habit, herbs were predominant and about the preference for substrates, holorupicolous species and epiphytes were most speciose. The richest rocky habitat type was woody thicket, with 122 exclusive species. In total, 27 of the species registered in our study are cited on official lists of endangered plant species from Espírito Santo state and Brazil. In addition, two new records of angiosperms for Espírito Santo flora and two new species were recorded for the area. Our data demonstrates the importance of the area for conservation of unique biodiversity that serves as a sanctuary for a rich rupicolous flora composed of endemic and endangered species, some of which are new to science.

“…These taxa differ from those that colonize outcrops from the southeast region (e.g. Meirelles et al 1999, Oliveira & Godoy 2007, with exception of widely distributed species such as Achyrocline satureioides (e.g. see Ribeiro et al 2007).…”

“…Each region is characterized by a restricted group of taxa from this family in generic or infra-generic level and only Tillandsia is common along Brazilian east coast (e.g. Meirelles et al 1999, Oliveira & Godoy 2007, França et al 2006. For this family, 50% of the species occurred only at Guariba.…”

-(Floristic diversity of two crystalline rocky outcrops in the Brazilian northeast semi-arid region). Floristic composition and structure of vegetation were studied in two rocky outcrop areas in the semi-arid region of northeastern Brazil. From April 2007 to September 2008, 18 monthly field trips were carried out. Vascular plants were randomly collected throughout the outcrop areas. For structural analysis, 30 plots of 1 × 1 m were set in the vegetation islands. The checklist presented combines 211 species (69 families and 168 genera), although only 56 species were collected in the plots. Fabaceae (18 spp.; 8.5%), Asteraceae (17 spp.; 8%), Orchidaceae (13 spp.; 6.1%), Euphorbiaceae (13 spp.; 6.1%), Bromeliaceae (10 spp.; 4.7%), and Poaceae (eight spp.; 3.8%) are the richest families. Overall, 1,792 shrub and herbaceous specimens were counted in the plots. The Shannon-Wiener (H) diversity index values were 2.572 and 2.547 nats individual -1 . The species that presented the highest absolute abundance values (number of plants) had low frequencies in the plots and vice-versa. The biological spectrum had a high proportion of phanerophytes and therophytes, followed by cryptophytes, chamaephytes, and hemicryptophytes. The studied flora shares floristic components similar to other rocky outcrop areas of the semi-arid region in northeastern Brazil, including in relation to dominant groups in the vegetation structure.Key words -Caatinga, inselbergs, life-forms, saxicolous plants RESUMO -(Diversidade florística de dois afloramentos rochosos cristalinos no semi-árido, nordeste do Brasil).Composição florística e estrutura da vegetação foram estudadas em dois afloramentos rochosos localizados no semi-árido do nordeste do Brasil. Foram realizadas 18 excursões mensais, de abril de 2007 a setembro de 2008. Plantas vasculares foram coletadas aleatoriamente, no afloramento como um todo. Para análise estrutural foram plotadas 30 parcelas de 1 × 1 m nas ilhas de vegetação. Foram encontradas 211 espécies (69 famílias e 168 gêneros), entretanto somente 56 espécies foram coletadas nas parcelas. As famílias com maior número de espécies foram Fabaceae (18 spp.; 9%), Asteraceae (17 spp.; 8,5%), Orchidaceae (13 spp.; 6,5%), Euphorbiaceae (13 spp.; 6,5%), Bromeliaceae (10 spp.; 5%) e Poaceae (oito spp.; 4%). Ao todo, foram contabilizados, nas parcelas, 1.792 indivíduos herbáceos e arbustivos. Os valores do índice de diversidade de Shannon-Wiener (H) foram de 2,572 e 2,547 nats ind.-1 . As espécies que apresentaram maiores densidade apresentaram baixa freqüência nas parcelas e vice-versa. O espectro biológico apresentou alta proporção de fanerófitos e terófitos, seguidos por criptófitos, caméfitos e hemi-criptófitos. A flora estudada compartilha conjunto florístico semelhante a outros afloramentos rochosos do Nordeste do Brasil, inclusive em termos de grupos dominantes na estrutura da vegetação.Palavras-chave -Caatinga, formas de vida, inselbergues, plantas saxícolas 1.

“…There are still typical CRs on the Ibitipoca range Chusquea, a typical element of campo de altitude, advocates for more abundant and better-distributed precipitation in Serra Negra, inserted in the forest zone rather than the savanna. On the Morro do Forno (state of São Paulo, 22° S, precipitation of 1517 mm/year), Oliveira and Godoy (2007) found several floristic elements typical of the CRs, such as Cambessedesia DC., Marcetia DC., Barbacenia Vand., Vellozia Vand., Xyris L. and Dicranopteris linearis (Burm. f.)

Circumscribing campo rupestre – megadiverse Brazilian rocky montane savanas

et al. 2014

Currently campo rupestre (CR) is a name accepted and used internationally by botanists, zoologists, and other naturalists, usually applied to a very specific ecosystem, despite the lack of a consensual published circumscription. We present a tentative geographic circumscription of the term, combining data on climate, geology, geomorphology, soil, flora, fauna and vegetation. The circumscription of campo rupestre proposed herein is based on the following premises:(1) the classification of vegetation is not an exact science, and it is difficult to attain a high degree of consensus to the circumscription of vegetation names; (2) despite this, vegetation classification is useful for conservation and management. It is thus desirable to circumscribe vegetation types with the greatest attainable precision; (3) there is a need to preserve all montane and rocky vegetation types, regardless of classification, biome, etc; (4) the CRs are formed by a complex mosaic of vegetation types including rock-dwelling, psammophilous, aquatic, epiphytic, and penumbral plant communities. Campos rupestres stricto sensu are a Neotropical, azonal vegetation complex endemic to Brazil, forming a mosaic of rocky mountaintop "archipelagos" inserted within a matrix of zonal vegetation, mainly in the Cerrado and Caatinga provinces of the Brazilian Shield (southeastern, northeastern and central-western regions), occurring mainly above 900 m asl. up to altitudes exceeding 2000 m, having measured annual precipitation between 800 and 1500 mm, and an arid season of two to five months.Keywords: rocky savana, montane savana, rock-dwelling vegetation, biogeographic elements, vegetation classification, Neotropics. Circunscrevendo campo rupestre -savanas montanas rochosas megadiversas do Brasil ResumoAtualmente campo rupestre (CR) é um termo aceito e internacionalmente usado por botânicos, zoólogos e outros naturalistas, geralmente aplicado a um ecossistema muito específico apesar de não haver uma circunscrição de consenso. Nós apresentamos uma ciscunscrição geográfica tentativa do termo, combinando dados de clima, geologia, geomorfologia, solo, flora, fauna e vegetação. A circunscrição de campo rupestre aqui proposta se baseia nas seguintes premissas: (1) a classificação da vegetação não é uma ciência exata e é difícil atingir um alto grau de consenso sobre a circunscrição de nomes de vegetação; (2) apesar disto, a classificação da vegetação é útil para conservação e manejo. Assim é desejável descrever os tipos de vegetação com a maior precisão tangível; exista a necessidade de se preservar todos os tipos de vegetação montanos e rochosos, independentemente de sua classificação, bioma, etc. (4) os CRs são formados por um complexo mosaico de tipos de vegetação incluindo comunidades sobre rocha, psamíóilas, aquáticas, epífitas e penumbrais. Os campos rupestres stricto sensu são um complexo de vegetação endêmico ao Brasil, azonal, Neotropical, inserido numa matriz de vegetação zonal, sobretudo nas províncias do Cerrado e da Caatinga do Escudo do Bra...
