“…These taxa are some of the most diverse families in Brazil (especially with regard to large woody species), and our findings are consistent with several studies conducted in the state of São Paulo (Assumpção et al 1982;Leitão-Filho 1987 al. 2004;Zipparro et al 2005;Oliveira and Godoy 2007;Pereira-Silva et al 2007;Franco et al 2007;Guaratini et al 2008) and more specifically in the administrative region of Sorocaba (Ivanauskas and Rodrigues 1999;Ishara et al 2008;Viani and Rodrigues 2009) on formations of SSF and Cerrado.…”

The Atlantic rain forest is in a very fragmented condition due to the high deforestation in recent decades, thus even remnants of secondary vegetation may be considered important for maintaining the ecological and microclimatic functions on a regional scale. This represents the first plant composition study conducted in the area, located in Sorocaba (São Paulo, Brazil), a region relatively unknown in terms of vegetation. Our aims were to survey the vegetation, verify the vegetation formation in which the sampled species occur and identify endangered species. Periodic samples of woody plants were conducted between September 2007 and December 2009. We found 166 species, belonging to 47 families and 102 genera; ten of these species are under threat of extinction. Our data substantially increase our knowledge of the diversity of the regional flora and will play a crucial role in developing conservation policy.

“…As famílias mais representativas foram Fabaceae (30 espécies), Myrtaceae (26), Asteraceae (24), Melastomataceae (20), Lauraceae (16) e Rubiaceae (15). Com exceção de Asteraceae, essas são as famílias mais freqüen-temente relatadas como as de maior riqueza em trabalhos publicados realizados em outros remanescentes da região do município de São Paulo e seu entorno, como a Serra do Japi, em Jundiaí (Leitão-Filho 1992), o fragmento estudado por Gandolfi et al (1995) em Guarulhos, a Reserva da Cidade Universitária Armando de Salles Oliveira -USP (Dislich et al 2001) e o Parque Santo Dias (Garcia & Pirani 2001), localizados na própria capital, a Reserva Florestal do Morro Grande ) e o Parque CEMUCAM (Ogata & Gomes 2006), no município de Cotia, os nove fragmentos estudados por Franco et al (2007) em Embu, e os 21 remanescentes florestais localizados no município de Ibiúna .…”

“…Merecem destaque Nectandra debilis Mez (Lauraceae), classificada como "criticamente em perigo" de acordo com a lista mundial e "em perigo" segundo a lista estadual, e Mollinedia oligotricha Perkins (Monimiaceae), incluída na categoria "presumivelmente extinta" no estado. A presença dessas espécies reforça a importância da conservação e proteção de remanescentes florestais, mesmo quando a vegetação é secundária ou quando há fortes pressões antrópicas no local, como enfatizado por Franco et al (2007).…”

composition of tree and shrub species of the Jaraguá State Park, São Paulo -SP, Brazil. Biota Neotrop., 9(2): http://www.biotaneotropica. org.br/v9n2/en/abstract?iventory+bn00909022009. Abstract:The objective of this study was to characterize the floristic composition of trees and shrubs of the Jaraguá State Park (PEJ), contributing to the knowledge of its biodiversity. Reproductive botanic material was collected along three trails during a 12-month period. The field survey resulted in a flora of 262 native species, 153 genera and 55 families. Fabaceae was the richest family (30 species), followed by Myrtaceae (26), Asteraceae (24), Melastomataceae (20), Lauraceae (16) and Rubiaceae (15). As mentioned for other forest remnants in São Paulo metropolitan region and surroundings, the PEJ vegetation is in a transition zone, where the main formation is the ombrophilous dense forest, but where species of seasonal semi-deciduous forest also occur. Besides that, there is a completely different phytophysiognomy occurring in a region with rocky outcrops and low depth soils, in which cerrado species were found, and that deserves more specific studies. In this site, the vegetation of grasses is the most abundant, and there are also shrubs and trees sparsely distributed, many of them with low height and suberous trunk. Most specifically in this area there were 55 species of 41 genera and 18 families, from which 22 did not occur in the other sites visited. Asteraceae was the family with the higher number of species (15), followed by Myrtaceae (7), Fabaceae (5) and Melastomataceae (4). Twenty exotic species were found along the trails. Despite the fact that PEJ has a big area of secondary vegetation and that it is exposed to strong anthropogenic pressures, there were 14 species belonging to some threat category defined at the official red lists, reinforcing the importance of the Park for biodiversity conservation.

“…The conservation of these remaining areas is also attributed to the presence of important conservation units (Franco et al 2007). Among those located in São Paulo State it may be cited as examples the Parque Estadual da Ilha do Cardoso, Estação Ecológica Juréia-Itatins and Parque Estadual da Serra do Mar.…”

This study aimed to map phytophysiognomies of an area of Ombrophilous Dense Forest at Parque Estadual da Serra do Mar and characterize their floristic composition. Photointerpretation of aerial photographs in scale of 1:35,000 was realized in association with field work. Thirteen physiognomies were mapped and they were classified as Montane Ombrophilous Dense Forest, Alluvial Ombrophilous Dense Forest or Secondary System. Three physiognomies identified at Casa de Pedra streamlet's basin were studied with more details. Riparian forest (RF), valley forest (VF), and hill forest (HF) presented some floristic distinction, as confirmed by Detrended Correspondence Analysis (DCA) and Indicator Species Analysis (ISA) conducted here. Anthropic or natural disturbances and heterogeneity of environmental conditions may be the causes of physiognomic variation in the vegetation of the region. The results presented here may be useful to decisions related to management and conservation of Núcleo Santa Virgínia forests, in general.
