“…This timber activity continued until the mid-1990s, after which the fragment remained "untouched." Nonetheless, the presence of sawmills was common in this region, giving evidence of exploitation into the mid-20th century (Moretto 2017).…”

Ecological restoration mitigates the negative effects of fragmentation and habitat loss. This practice allows the conservation of key species, such as Ocotea porosa, a tree native to the Araucaria Forest and extremely endangered. A key point in restoration projects is the source of seeds, as well as guidelines for collection. When carried out under technical criteria, the collection allows the maintenance of genetic diversity and adaptive potential in restoration plantations. Given the importance of seed source, genetic diversity, and adaptive potential, this study aimed to define areas and criteria for collecting seeds by characterizing the demography, genetics, and reproductive phenology of an O. porosa population. A plot of 16 hectares was installed in the municipality of Passos Maia, Santa Catarina, Brazil, and a demographic survey of trees with diameter at breast height (DBH) > 15 cm was carried out. Indices of diversity and internal genetic structure (IGS) were estimated using allozyme markers. The reproductive phenology of 67 individuals was evaluated during 8 months. The studied population showed a high density of individuals (10.7 ind. ha-1) with normal diametric distribution. The phenological pattern of the species is regular, seasonal, and annual. The evaluated population showed high genetic diversity, high fixation index, and significant IGS up to 80 meters away. Based on these results, the evaluated fragment can be used as a seed collection area. It has high genetic diversity, density, and area size sufficient to contain several demes. In addition, it is highly recommended that the matrices be at least 80 meters apart to avoid the effects of significant IGS.

“…The growth of the productive activities intensified the deforestation of the Atlantic Forest, causing more significant pressure on native species such as E. involucrata, which signals the importance of developing public policies to ensure species and ecosystems conservation (Lisbôa et al 2011, Oliveira 2017. This is the case in the western and Serrana regions of Santa Catarina, a state in southern Brazil, where the historical expansion of logging exploitation, agriculture and livestock had a profound effect on the landscape (Oliveira 2016a, Moretto 2017. Due to the rural exodus being a relatively recent phenomenon in the interior of Santa Catarina, the inland communities own a regional peculiarity, where a rurality character persists even among the urban communities, that maintain a link to the rural environment and share a local identification with the profile of countryside (Oliveira 2016b).…”

Background: Eugenia involucrata (cerejeira do mato) is a fruit species from the Atlantic Forest Biome, which presents several potential uses; however, it is considered an endangered species. An ethnobotanical survey and physical-chemical evaluations were carried out in order to characterize the local knowledge about E. involucrata, the variability maintained by local communities and identify fruits with agronomic traits of interest.Methods: The study was conducted in the counties of Curitibanos, Frei Rogério, and Rio das Antas. Ethnographic research was used to gather ethnobotanical knowledge. Fruit samples from seven plants owned by family units were evaluated for diameter, height, pH, vitamin C, titratable acidity, and total soluble solids.Results: Nineteen family units were interviewed, where eleven use purposes and fifteen agricultural management practices were mentioned for Eugenia involucrata. The main criteria indicated by people interviewed for E. involucrata selection were "sweeter fruits," "darker fruits" and "larger fruits.". There was variability among the seven accessions of E. involucrata evaluated. The accessions 3.D, 4.MI, 5.MII and 6.G were the ones that best met the selection criteria. The affective bond, related to familiar or childhood traditions has contributed to the conservation of E. involucrata.Conclusions: The family units interviewed share a cultural relationship with E. involucrata, which has been perpetuated over generations through the continuous use of the species. Among the genetic variability maintained by the family units, the accessions 3.D, 4.MI, 5.MII and 6.G were those which best attend the selection criteria established.
