Inventário Florístico Florestal de Santa Catarina: espécies da Floresta Estacional Decidual

Abstract

O presente trabalho visou apresentar e analisar a flora da Floresta Estacional Decidual em Santa Catarina, Brasil, tendo como fonte de dados os levantamentos realizados durante o Inventário Florístico Florestal de Santa Catarina. Foram avaliadas as espécies de indivíduos lenhosos de 79 unidades amostrais de 4.000 m². Foram feitas coletas extras de indivíduos férteis, no entorno e nas unidades amostrais, das demais formas de vida. Este esforço amostral registrou 420 espécies, abrangendo 90 famílias e 275 gêneros. Nas unidades amostrais, registrou-se 233 espécies, sendo 204 com diâmetro na altura do peito (DAP) > 10 cm e 162 com diâmetro na altura do peito DAP < 10 cm e altura > 1,50 m, portanto com espécies em comuns. A coleta de material extra registrou 332 angiospermas e uma gimnosperma (Araucaria angustifolia), demonstrando a importância de coletas externas às áreas previamente delimitadas. Entre as ameaçadas de extinção foram registradas Ocotea odorifera e Araucaria angustifolia.

Vertical Structure of the Arboreal Component Under Regeneration Phase of a Deciduous Forest Fragment, Santa Catarina State, Brazil

“…(Table 1) represent more than 25% of the total value of this parameter. GASPER et al, 2012;GASPER et al, 2013). However, researches involving the assessment of the vertical distribution of arboreal species in this region are still poorly developed, especially due to the difficulty of identifying the species in juvenile stages (POLISEL, 2013).…”

“…The municipalities of Piratuba and Ipira have a population density of 33 and 30 inhabitants per km 2 , respectively (IBGE, 2013). In Piratuba, the industrial activities related to the agribusiness contribute to 50.6% of the GNP; in Ipira, the service sector and agriculture account for more than 80% of this indicator (SEBRAE, 2010a;SEBRAE, 2010b).…”

“…Currently, the urbanization process has provided significant changes in the relationships of the resources on the edge and inside forest (MOTTER;FIGUEIRÓ, 2010;GASPER et al, 2012;VIBRANS et al, 2013a;SCHROEDER, 2013). However, the territory of Santa Catarina has the largest area of remaining Atlantic forest, which represents 16% of SDF (IBGE, 2013;VIBRANS et al, 2013b).…”

Floristic, Diversity and Spatial Distribution of Tree Species in a Dry Forest in Southern Brazil

“…The Myrtaceae family has its participation justified by its broad longitudinal distribution spectrum (Negrelle, 2013). However, Gasper et al (2013) claim that this family is best represented in the rain forests than in the seasonal forests, tending to decline in richness in the Cerrado and According to Ribeiro and Lima (2009) the Fabaceae (Leguminosae) family is more diversified in seasonal environments, which can be explained from the Tertiary, when the dry forests dominated the major regions of the world, from where the association of legumes with nitrogen-fixing bacteria created efficient evolutionary mechanisms, providing greater plasticity for the occupation in poor environments in nutrients and regeneration.…”

“…The species C. canjerana and P. rigida, common in DSF, are also present with relative abundance in the Dense Ombrophilous Forest (DOF) in Santa Catarina Gasper et al, 2013). For these authors, A. concolor is one of the main species in regenerating layers of DSF, but it rarely appears in DOF.…”
