Vascular flora of the Mata dos Godoy State Park, Londrina, Paraná, Brazil

Abstract

The Mata dos Godoy State Park (MGSP) is a remnant of the Seasonal Semideciduous Forest in northern Paraná, with an area of 690 hectares. The MGSP flora inventory was produced from a survey of herbarium specimens deposited in the FUEL Herbarium. The result was the catalogue of 508 species, among which we screened 40 specimens of ferns and lycophytes, and the remainder was classified as angiosperms. The two richest families among the ferns were Polypodiaceae and Pteridaceae, whereas among the arboreal angiosperms, Leguminosae and Myrtaceae stood out, confirming the floristic profile of the lower Tibagi River basin. Among the species, 12 can be classified as naturalized and 21 are among the threatened species in the state of Paraná, besides the inclusion of species whose collections were reduced in Brazil. These results indicate the MGSP as an important area for the representation of the Seasonal Semideciduous Forest in northern Paraná.

Tree and shrub flora in the surroundings of the Parque Nacional do Iguaçu, Paraná State, Brazil: contribution to ecological restoration

“…The distribution of species richness among families in the study area was similar to that found in other seasonal semideciduous forest studies in the Brazilian States of São Paulo (Cielo-Filho et al 2009, Souza et al 2012 and Paraná (Viani et al 2011, Gris 2012, Zama et al 2012, Rossetto & Vieira 2013; in the Province of Misiones, Argentina (Chediack 2008, Velazco et al 2015; and in the Departments of Canindeyú and Alto Paraná, Paraguay (Monge 2009). However, an interesting feature of the study area was the relatively low representativeness of Lauraceae and the relatively high richness of Solanaceae.…”

“…However, as pointed out by these authors, the high richness in those areas may be related to the presence of Cerrado remnants in the region, which would expand the regional species pool, increasing the richness in remnants of seasonal semideciduous forest. Even without the influence of the Cerrado flora, the number of tree and shrub species (266) reported by Rossetto & Vieira (2013) for the seasonal semideciduous forest of the Mata dos Godoy State Park, northern Paraná State, was higher than that found in the present study.…”

“…For instance, the number of tree species (197) reported for the Mata dos Godoy State Park, where a comprehensive floristic study in a well conserved forest remnant was carried out (Rossetto & Vieira 2013), was greater than that found in our study (174), as well as in the studies of Souza (2015) and Gris (2012) which identified, respectively, 165 and 112 native tree species in the INP and forest fragments nearby. However, when considered together, the floristic data available for the study area and its surroundings -this study, Gris (2012) and Souza (2015) -summed up 228 native tree species, what suggests that the tree flora in northern remnants of seasonal semideciduous forest of the Paraná State is not richer than in southern ones.…”

“…This could suggest a particularity of the flora of seasonal semideciduous forest remnants located in higher latitudes of the Paraná State, but, instead, seems to be a consequence of forest fragmentation or sampling effect, as discussed above. For instance, we recorded only six species of Lauraceae, but this number increases to 10 considering the results of floristic surveys nearby (Gris 2012, Souza 2015, equaling the number found in the Mata dos Godoy State Park in northern Paraná (Rossetto & Vieira 2013). In relation to Solanaceae, the number of tree and shrub species found in the Mata dos Godoy State Park, 19, was even higher than that found in the study area and its surroundings, 15 (this study, Gris 2012, Souza 2015.…”

A vegetação da Estação Ecológica de Xitué, Ribeirão Grande-SP: subsídios para o plano de manejo.

“…A têm revelado centenas de espécies ocorrendo em áreas relativamente pequenas (Thomas et al, 1998;Amorim et al, 2009;Cielo-Filho et al, 2009;Saiter et al, 2011;Rossetto e Vieira, 2013). Essa grande diversidade de espécies arbóreas observada em florestas tropicais decorre dos padrões de distribuição de abundância verificados nessas florestas.…”
