“…Estudos realizados em diferentes locais na floresta Amazônica encontraram entre 118 e 307 espécies de árvores (≥ 10 cm dap) por hectare. Bombacaceae, Burseraceae, Chrysobalanaceae, Lauraceae, Lecythidaceae, Leguminosae, Moraceae, Sapotaceae e Vochysiaceae são as famí-lias com maior riqueza de árvores naquelas florestas (Veloso 1946, Prance et al 1976, Campbell et al 1986, Gentry & Terborgh 1990. As árvores (≥ 10 cm dap) constituem somente entre 15 e 22% das espécies nas florestas neotropicais onde há floras conhecidas (Gentry & Dodson 1987).…”

-(Woody species richness in the Brazilian atlantic forest, state of São Paulo (Brazil)). The atlantic forest in São Paulo state, has been described in the scientific literature as having high floristic diversity. Such statement is based on data and conclusions of local floristic and phytosociological studies. However, the studies supporting this idea seldom give a clear definition of the plant group analysed, the scale of the study, nor, most significantly, the forests used for comparisons. Here we compare woody species richness data (≥ 2.5 cm dbh) from the atlantic forest in São Paulo to similar data from other neotropical forests. Thereafter, we discuss the major relationships between historical and ecological processes and woody species richness in neotropical forests. Neither data on woody species richness nor characteristics of latitude, altitude, rainfall and soil in the atlantic region is able to support the idea of high woody species richness in the São Paulo atlantic forest. Studies using comparable data sets are required in order to characterise woody species richness in all types of the atlantic forest, as well as to suggest the mechanisms responsible for plant richness in different scales.RESUMO -(A riqueza de espécies arbóreas na floresta atlântica de encosta no estado de São Paulo (Brasil)). Extensa literatura referese à floresta atlântica de encosta no estado de São Paulo como possuidora de elevada diversidade florística. Esta afirmação está baseada em dados e conclusões de estudos florísticos e fitossociológicos locais. A maioria destes trabalhos não define com clareza o que considera diversidade, de que grupos estão tratando, a escala de abordagem e, principalmente, quais as florestas usadas para comparação. Neste estudo, são comparados dados sobre riqueza de plantas arbóreas (≥ 2,5 cm dap) na floresta atlântica de encosta em São Paulo com os de outras florestas neotropicais. Posteriormente, são discutidas as principais relações conhecidas entre a riqueza de plantas lenhosas nas florestas neotropicais e fatores históricos e ecológicos. Nem os dados sobre riqueza nem as características de latitude, altitude, precipitação e solo na região da encosta atlântica suportam a hipótese de riqueza elevada nesta floresta em São Paulo. Estudos realizados a partir de base de dados comparáveis são necessários para caracterizar a riqueza de espécies lenhosas em todos os tipos de floresta, bem como para sugerir hipóteses sobre os processos responsáveis pelos padrões observados em diferentes escalas.

“…tions in a restricted area, a definition of vegetation types by structure is not only more practical, but based on more fundamental criteria. It is well.known that vegetation in the tropics is less homogeneous than in temperate climates (SCHIMPER, 1898, WARMING, 1899, 1909. Equatorial rainforest is sup.…”

“…These studies were primarily focused on the transmission of yellow fever and included surveys of the hosts and vectors of the disease (Martins 1989). Subsequent studies by Veloso were more interested in the AF itself and included the first attempts at defining species associations and estimating tree species diversity (Veloso 1946;Klein 1957, 1968). Until the end of the 1970s, few other studies were published, most attempting to assess AF timber potential (Cain et al 1956;Campos and Heinsdijk 1970;Tavares et al 1971).…”

How much do we know about the endangered Atlantic Forest? Reviewing nearly 70 years of information on tree community surveys

The structure of the Atlantic Forest (AF) has been studied for almost 70 years. However, the related existing knowledge is spread over hundreds of documents, many of them unpublished and/or difficult to access. Synthesis initiatives are available, but they are restricted to only a few parts or types of the AF or are focused on species occurrence. Here, we conducted an extensive review to compile quantitative tree community surveys on all types of the AF until 2013 and to study where and how these surveys were conducted. We found 1157 relevant references, containing 2441 forest surveys published since 1945. These surveys corresponded to 2.24 million trees and 1817 ha of forests sampled. This total sampled area represents only 0.01 % of the AF remnants, showing how limited our knowledge is on AF structure. For Paraguay and the Brazilian states of Bahia and Mato Grosso do Sul this proportion was much smaller. The same was true for evergreen rainforests, Brejos de altitude and deciduous forests and most probably for the rare cloud, swamp, Caxetal and Mussununga forests for which no accurate remnant estimates were Communicated by Jefferson Prado, Pedro V. Eisenlohr and Ary T. de Oliveira-Filho.Electronic supplementary material The online version of this article (found. Since the 1980s, the amount of AF area sampled each year has increased continuously, but approximately 100 years will be necessary to sample at least 1 % of the AF. Thus, we urgently need an enormous amount of high-quality quantitative data to overcome our limited knowledge of the AF and to support conservation programs aiming to safeguard this threatened biodiversity hotspot.
