AuthorshipSCIMAGO INSTITUTIONS RANKINGS

    Abstract

    This study aimed to determine the tree structure, floristic composition and species diversity in the Araucaria State Park, southern Brazil. We allocated 100 plots of 100 m2 (1 ha) each one, and we recorded all trees with diameters at breast height ≥ 5 cm. We sampled 1368 individuals of 106 species, 75 genera and 44 families. Fabaceae, Lauraceae and Myrtaceae showed the greatest richness of species. The diversity of tree species was high (H ‘= 3.96), although the observed richness was less than the estimated one. The basal area was 46.88 m2 ha-1. We observed an intrinsic association between Araucaria angustifolia and Nectandra megapotamica, and a predominance of secondary and zoochorous (> 70%) species. Endangered and vulnerable species in the Santa Catarina state, such as Araucaria angustifolia, Cedrela fissilis, Dicksonia sellowiana and Ocotea porosa were sampled in the Park, highlighting its importance for the conservation of the Mixed Ombrophylous Forest.

    1. INTRODUCTION AND OBJECTIVES

    The Mixed Ombrophylous Forest (MOF), also called Araucaria Forest, is predominantly distributed in southern Brazil, with small patches in southeastern Brazil, in the far northeast of Argentina and east of Paraguay (IBGE, 2012; Klein, 1960). In Santa Catarina state (SC), this forest originally occupied 45% of the total area covered by natural forests (Vibrans et al., 2013). However, since the end of the 19th century, the area of MOF has been reduced by anthropic action such as firewood for domestic purposes, timber industry, agribusiness, and urbanization (Carvalho, 2012; Rondon Neto et al., 2002a; Sevegnani et al., 2012). Currently, MOF is highly reduced and fragmented (Shaw, 2019) to about 25% of the original area of MOF remaining in SC (Vibrans et al., 2013). Part of these MOF areas are protected in Conservation Units (UC).

    Despite the ecological, economic and cultural importance of MOF for the state of SC, there are still great gaps in the knowledge of its composition and structure. Some studies in floristics and phytosociology were developed for the northern plateau of state (Formento et al., 2004; Gasper et al., 2013a,b; Herrera et al. 2009; Lingner et al., 2007; Negrelle & Silva, 1992) and there has recently been an important increase in such knowledge for the southern plateau of state (Dallabrida et al., 2018; Higuchi et al., 2013; Klauberg et al., 2010; Manfredi et al., 2015; Martins et al., 2012; Santos et al., 2018; Silva et al., 2016). In a review of phytosociological studies in MOF for southern Brazil, we found no studies for the western region of SC. Data from this region is available only from the systematic survey of the Forest Floristic Inventory of Santa Catarina (IFFSC) (Gasper et al., 2013a,b). In IFFSC survey, 0.4 ha plots were set 10 km apart one from another, where all trees with diameter at breast height (DBH) ≥ 10 cm were sampled (Vibrans et al., 2010). We also highlight the pioneering study on SC flora carried out by Roberto Miguel Klein and Fr. Raulino Reitz. These studies resulted in the publication of Flora Illustrated Catarinense, which greatly contributed to the floristic knowledge of the western region (Klein, 1960, 1978; Reitz, 1965). Even so, there is a gap in the floristic, phytosociological, and structural knowledge of the MOF for the western region of SC.

    In accord to Klein (1960), MOF presents distinct floristic associations in southern Brazil. For this reason, local and regional knowledge of biodiversity is essential, as it allows the identification of stenotopic species, which are unable to tolerate drastic changes in the environment, occupy specific ecological niches, and have a restricted geographical distribution (Dajoz, 1983). Therefore, regional floristic knowledge is essential both for the conservation of these associations and for subsidising projects for the restoration of degraded areas according to the regional composition. We must highlight that the MOF in western SC is neighboring the Seasonal Deciduous Forest, which makes the flora of this region very peculiar (Klein, 1978).

    The Araucaria State Park (PEAR) with an area of 612 ha is one of the last MOF conserved remnants in western SC (FATMA, 2015). PEAR is subject to high anthropic pressure, because it is immersed in an agricultural matrix that reduces connectivity with other fragments. The New Brazilian Forest Code (Brazil, 2012) determines the forest restoration of areas of permanent preservation and legal reserve, which are essential for the formation of ecological corridors. Connecting the MOF fragments is important for maintaining the biological and genetic diversity of populations. In addition, Brazil committed to restoring and reforesting 12 million hectares of forests by 2030 in the Paris Agreement (FGV, 2018). In this context, the study on getting to know about structure and floristic composition at the local and regional level is urgent and plays an important role as a source of information to support for forest restoration projects.

    This study aimed to characterise the structure, tree floristic composition, and tree species diversity of PEAR. Its results can serve as a reference for the region’s floristic structure and composition, subsidising environmental restoration projects.

    2. MATERIALS AND METHODS

    2.1. Study area

    The Araucaria State Park - PEAR (26º27’08” S and 52º33’56” W) is located in the municipalities of São Domingos and Galvão, western SC (Figure 1). Before the establishment of PEAR in May 2003, part of the area was used for the extraction and processing of wood, especially Araucaria angustifolia (Bertol.) Kuntze (FATMA, 2015). Until May 2003, some areas had not been explored, and others were in the process of regeneration. Therefore, the PEAR landscape is made up of forest patches in different successional stages.

    Figure 1
    Location of Parque Estadual das Araucárias, western Santa Catarina (SC), southern Brazil.

    According to the Köppen classification, the region’s climate is of the Cfb type - with mild summers (Alvares et al., 2013). Temperatures in the coldest month range from -3 °C to 18 °C, and temperatures in the hottest month are over 22 °C. The average annual precipitation is approximately 2,400 mm (Santa Catarina, 1986).

    2.2. Sampling and data analysis

    On a PEAR map we systematically allocated 100 plots of 100 m² (10 m x 10 m) totaling 1 ha, seeking to represent all areas of the PEAR, but avoiding those that are difficult to access or particularly degraded. These plots were later demarcated in the field. We sampled all tree individuals with DBH ≥ 5 cm. The identification of plants was carried out in the field or after collection and herborisation by consulting herbarium collections, the literature’s bibliography, and specialists. The list of species was grouped by family according to the APG IV system (APG, 2016), and the name of the species and their authorship are in agreement with “Flora do Brasil” (http://floradobrasil.jbrj.gov.br).

    The rarefaction curve was calculated in order to compare the observed richness to the estimated richness by the Jackknife2 method, using the EstimateS 9.1.0 software (Colwell, 2013) with 100 randomisations of the sample order and a 95% confidence interval. In accord to Oliveira et al. (2016), Jackknife2 is the best diversity estimator for SC forests.

    We calculated density, dominance, frequency (absolute and relative), Importance Value Index (Mueller-Dombois & Ellenberg, 1974) and Shannon’s diversity and Pielou’s equability indices (Ludwig & Reynolds, 1988) in the Mata Nativa 2 software (Cientec, 2006).

    The sampled individuals were grouped into seven classes of diameter: 5 cm ≤ 10 cm; > 10 cm ≤ 20 cm; > 20 cm ≤ 30 cm; > 30 cm ≤ 40 cm; > 40 cm ≤ 50 cm; > 50 cm ≤ 60 cm; > 60. Additionally, the species were classified into successional categories (pioneer, secondary and climax) according to Backes & Irgang (2002), Carvalho (2006), Lorenzi (2008) and Meyer et al. (2013) and as for the dispersal syndrome (zoochorous, anemochorous and autochorous), according to Van der Pijl (1982).

    3. RESULTS AND DISCUSSION

    We sampled 1368 individuals from 106 species, distributed in 75 genera and 44 families (Table 1). In 1 ha of MOF in the southern plateau of SC, Higuchi et al. (2013) sampled 1395 individuals of 50 species, 33 genera and 20 families. Herrera et al. (2009) analysed 2.6 ha in the northern plateau of SC, but with inclusion criteria for DBH ≥ 10 cm, sampling 71 species, distributed in 54 genera and 33 families. Therefore, this study showed the high diversity of tree species in the PEAR, resulting from the different successional stages present in the area.

AD: absolute density; SC = successional category (P= pioneer, S = secondary, C = climax); LF= life form (T = tree, ST= small tree, TF = tree fern, SH = shrub, P = palm tree) (in accord with VIBRANS et al., 2013); DS= dispersal syndrome (Z= zoochory, A = anemochory, Au = autochory).

    The analysis of the rarefaction curve has showed that the observed richness was less than the richness estimated by the Jackknife2 estimator, indicating that the species richness may be greater than that sampled (Figure 2). Higuchi et al. (2013) also have recorded observed richness lower than the estimated richness in MOF remnant in the southern plateau of Santa Catarina, using the same estimator. According to the authors, the high floristic diversity of the studied fragment, due to the presence of several patches in different successional stages, caused this difference in richness, similar to the present study.

    Figure 2
    Observed richness (dark solid line) with a 95% confidence interval (dashed lines) and the estimated richness by the Jackknife2 estimator (light solid line) for the tree component of the Parque Estadual das Araucárias, Santa Catarina, southern Brazil.

    The families with the highest specific richness were Fabaceae (14 spp.), Lauraceae, Myrtaceae (8 spp.) and Meliaceae (7 spp.). These families, added to Rutaceae, Salicaceae, Sapindaceae and Solanaceae accounted for more than 50% (55 spp.) of the sampled species (Table 1). Except for the high specific richness of Fabaceae, this floristic pattern has been found in surveys of the MOF (Klauberg et al., 2010; Lingner et al., 2007; Martins-Ramos, et al. 2011; Seger et al., 2005). Fabaceae and Myrtaceae are considered the families with the highest specific richness in seasonal forests, while Lauraceae is mainly associated with the MOF in southern Brazil (Reitz et al., 1978). The found family composition reflects the environmental characteristics of PEAR, which involves a transition area between the MOF and the seasonal deciduous forest.

    In a natural regeneration study carried out in the PEAR (Passos, 2016), A. angustifolia has showed a total natural regeneration rate of 0.1%, which indicates a low potential for regeneration of the species in the area. The low regeneration of A. angustifolia, the high specific richness of Fabaceae and Myrtaceae, and the proximity of the fragments to the Deciduous Seasonal Forest suggest that the forest formation in the PEAR undergoes a process of floristic change. This observation corroborates the information about the expansion of the distribution area of Mimosoideae species (Fabaceae) for the forests of the Santa Catarina plateau (Amaral et al., 2015). Maack (1981) considered the possibility of retraction of the MOF, which would be confined to areas of subtropical climate, while Klein (1978) reported a tendency of expansion of the seasonal deciduous forest on the MOF. However, Orihuela et al. (2015) have recorded that MOF and seasonal deciduous forests shared 31% of species. In this context, long-term monitoring of the PEAR forest structure can contribute to the understanding of this issue.

    Of the 106 species sampled, 15% (16 spp.) were represented by an individual and can be considered locally rare. This data highlights the importance of PEAR, as rare species are important for ecology and conservation, in addition to being frequently the focus of political decisions (Lim et al. 2012). In a Lauraceae rarity analysis carried out for the SC plateau, 59.4% of the species were considered rare in this region, with a high percentage of stenotopic (43.2%) and stenoic (40.5%) species (Fontana et al., 2016).

    Compared to the results of the IFFSC (Gasper et al., 2013b), 198 species cited for the MOF were not sampled in the PEAR, which confirms the floristic heterogeneity of the MOF throughout its distribution area (Leite & Klein, 1990). On the other hand, two species (Symplocos pentandra (Mattos) Occhioni ex Aranha and Symplocos uniflora (Pohl) Benth) mentioned for the MOF (Reitz et al., 1978), and not sampled by the IFFSC (Gasper et al., 2013b), were registered in the present study. These results prove the importance of regional floristic surveys for the knowledge of the flora of the MOF.

    The five species with the highest Importance Value Index (VI) were Nectandra megapotamica, A. angustifolia, O. diospyrifolia, L. divaricata and I. paraguariensis (Table 2). The dominance of A. angustifolia contributes to its high value of VI. The species with the highest density were N. megapotamica, I. paraguariensis, L. divaricata, Ateleia glazioveana, and Coussarea contracta. The first three species and Ocotea diospyrifolia also presented the highest frequencies. The species with the greatest dominance were A. angustifolia, N. megapotamica, O. diospyrifolia, L. divaricata, and Ocotea puberula (Table 2). Nectandra megapotamica, the species with the highest VI, occupied different microhabitats, and can be classified from climax to pioneer in secondary vegetation (Backes & Irgang, 2002).

AD = absolute density, RD = relative density (%), AF = absolute frequency (%), RF = relative frequency (%), ADo = absolute dominance, RDo = relative dominance, VI (%) = (RD + RF + RDo)/3.

    Analysing studies carried out in the northern plateau of SC (Lingner et al., 2007; Negrelle & Silva, 1992) and the results of this study, we have observed that A. angustifolia, Ilex paraguariensis, Cupania vernalis, and O. puberula were among the 10 species with the highest VI values. There has been a strong association between A. angustifolia, and O. porosa (Klein, 1978) for the northern plateau of SC, sharing in addition to the high VI, high density, dominance, frequency and basal area. In comparison to the studies carried out in the southern plateau of SC (Higuchi et al., 2013; Klauberg et al., 2010; Martins et al., 2012), we have observed that A. angustifolia, Dicksonia sellowiana, Cupania vernalis and Ocotea puberula were among the 10 species with the highest VI values. There is also a greater association between A. angustifolia with O. puchella and O. puberula for the southern plateau. However, at altitudes above 1,200 m in the southern plateau, Drimys angustifolia (Higuchi et al., 2013; Martins et al., 2012) and Drimys brasiliensis (Higuchi et al., 2013) have appeared among the species with the highest VI.

    When we compared the phytosociological results of the PEAR with the studies carried out in the northern plateau of SC, we have observed that A. angustifolia, C. vernalis, and O. puberula were among the main species in the structure and composition of the tree communities (Lingner et al., 2007; Negrelle & Silva, 1992). However, when we compared with the studies of the southern plateau of SC, we have observed the relevance of A. angustifolia, D. sellowiana, and I. paraguariensis (Higuchi et al., 2013; Klauberg et al., 2010; Martins et al., 2012). In addition to A. angustifolia, C. vernalis is among the species with the highest VI in all regions. The differential characteristics of the PEAR tree community, representative of the western region of SC, are the association of A. angustifolia and N. megapotamica (both with high VI, density, dominance, frequency and basal area) and the absence of Drimys spp. and Podocarpus spp.

    The total basal area was 46.88 m2 ha-¹, one of the highest values recorded for the MOF in southern Brazil (Table 3). Values greater than 35 m2 ha-1 can be expected for conserved forests, while values close to 22 m2 ha-1 can be expected for secondary succession phases (Longhi, 1997). Based on this criterion, it can be considered that the PEAR is in an advanced stage of ecological succession.

AR - area of the studied remnant (ha); SA - sampled area (ha); CI - criterion for inclusion of individuals (diameter at breast height (≥ cm); AD: absolute density (ind ha-1); BA: basal area (m² ha-1); H’: Shannon’s diversity index; J: Pielou’s equability index.

    Shannon’s diversity index was 3.96 nats ind-1, higher than those recorded in other studies (Table 3). The Pielou equability index was 0.85 nats ind-1, which is similar to that recorded in other studies (Table 3). Despite the differences in the inclusion criteria and the area studied between some studies, it is possible to conclude that the PEAR presents a high diversity of tree species and that there is not a strong dominance of one or some species, regarding the distribution of individuals.

    Individuals were sampled in all diametric classes, with a greater number of individuals from the first to the last class, which resulted in inverted J-shaped distribution (negative exponential model) (Figure 3). This distribution pattern has been observed in several studies at MOF in southern Brazil (Herrera et al., 2009; Klauberg et al., 2010; Rondon Neto et al., 2002a,b). In most species, individuals were concentrated in the diametric classes of up to 20 cm of DBH. Among them, we can mention A. angustifolia, which presented a multimodal distribution, which is typical of forests in which this species has been exploited (Herrera et al., 2009). However, the greater presence of individuals in the smallest diametric class does not mean that regeneration problems do not exist (Carvalho et al., 2007), and a specific study on regeneration must be performed.

    Figure 3

    Secondary species (63% of species) are the majority in the area, followed by pioneers (24%), climax (9%) and unclassified species (4%). The predominance of secondary and pioneer species is related to the history of the use of the area. Some areas of the PEAR are covered by grasses interspersed with yerba mate (Ilex paraguariensis) and in some areas, inside the forest, a massive presence of bamboo (Merostachys multiramea) occurred (personal observation). The bamboo may be the cause of the reduction in the regeneration of the dominant tree species in the understory of the MOF (Sanquetta et al., 2005). Thus, in the most disturbed areas of the PEAR, pioneer species, such as Ateleia glazioveana and Merostachys multiramea, predominated. However, in the most conserved areas, climax species of Myrtaceae and Lauraceae were observed, in addition to Dicksonia sellowiana (personal observation). Regarding the dispersal syndrome, 70.7% (74) of the species are zoochorous, 27.3% (29) anemochorous and 2% (3) autochorous. Dispersal by animals is expected for the MOF (Klauberg et al., 2010). According to Mikich & Silva (2001), vegetation complexity increases in forests in more advanced successional stages attracting birds and mammals. Therefore, we must conserve the fauna in these forests for processes such as pollination, dispersal and regeneration to occur.

    Preliminary data from the PEAR Management Plan indicate the occurrence of 281 species of birds and 31 small and medium-sized mammals (FATMA, 2015). However, some factors can negatively affect the regeneration process of tree species. Alves (2008) has observed a high population density of Sapajus nigritus Goldfuss, 1809 (capuchin monkey) in the PEAR. Researchers and park rangers observed in situ (personal communication) S. nigritus feeding on shoots of Syagrus romanzoffiana or on the bark of young plants of A. angustifolia, which can result in the death of individuals. There are also reports of early extraction of pine cones in the PEAR, which can affect the regeneration of A. angustifolia.

    Among the species sampled in the PEAR, many of them are on the list of vulnerable and threatened species. According to the Ministry of the Environment (MMA, 2014), A. angustifolia, Diksonia sellowiana and Ocotea porosa are classified as at risk of extinction, while Apuleia leiocarpa is classified as vulnerable. According to the list of the International Union for Conservation of Nature (IUCN, 2015), in addition to the species mentioned, Cedrela odorata (vulnerable), Balfourodendron riedelianum, Cedrela fissilis and Cedrela lilloi (endangered) are also included.

    4. CONCLUSION

    Despite past anthropogenic disturbances, the diversity of tree species is high (106 species per hectare), and there is an intrinsic association between A. angustifolia and N. megapotamica. The analysis of the data has indicated a predominance of secondary tree species, as the PEAR presents forest patches in several successional stages. More than 70% of the sampled species were zoochorous, demonstrating the fragment’s importance for maintaining the region’s fauna diversity. We also highlight the importance of PEAR for hosting endangered and vulnerable species of Santa Catarina flora. Therefore, PEAR can act as a reference for MOF restoration projects in western Santa Catarina, and as a source of propagules for species.
