“…As for the specific richness of the botanical families, it was found that the most frequent families observed together had approximately half of the species observed. The leadership of the families Myrtaceae, Lauraceae, Fabaceae, Salicaceae, and Rubiaceae in the tree composition agrees with the studies conducted in this forest typology in many localities [51,52,55,56,58,59,61,63,[68][69][70]72,73].…”

“…Regarding the horizontal structure, we found tree densities that are many times higher than in other MOF remnants located in protected areas, such as the "Parque Estadual das Araucárias" (SC, Brazil), with a density of 1368 trees ha −1 [64], and in FLONA (Irati, PR) with 567 trees ha −1 [63] and 561 trees ha −1 [59]. However, the basal area of the studied urban forests was smaller than that observed in the FLONA in São Francisco de Paula (RS, Brazil; 79.05 m 2 ha −1 ), although the density of 1445 trees ha −1 was smaller than that observed in the studied remnants [55].…”

“…The species A. angustifolia presented the highest IV in ZOOM (33.9%) and the second highest in BARI (20.4%). Although A. angustifolia is the most characteristic species of the studied phytophysiognomy, appearing with the highest IV in the other works [51][52][53][54][55][56][57][58][59], this species was not positioned in the BARE ranking. In BACA, A. angustifolia had an IV of 10.7% and was ranked 11th, behind Mollinedia clavigera.…”

The assessment of the conservation status of urban forest remnants is essential for sustaining tree diversity in metropolitan cities. This study evaluated the composition and structure of forest remnants in four urban parks within the natural distribution of Montane Mixed Ombrophilous Forest in Curitiba (PR, Brazil). We allocated 66 plots of 100 m2 and recorded all trees with perimeters at breast height ≥ 15 cm. A total of 1256 individuals from 44 botanical families and 117 tree species were identified, of which three are alien species. Tree density ranged from 1670 to 2095 trees ha−1, while the density of standing dead trees varied between 90 and 188 trees ha−1. We experienced values for the Shannon diversity index between 3.00 and 3.52 nats ind−1, which are comparable to the values for other non-urban forest remnants. Non-pioneer species represented 84.6% of the tree community (99 spp.), and 76% were zoochoric species (89 spp.). The research findings feed the discussion on the need of specific and integrated measures for the management of the urban parks reserved to the conservation of tree diversity in a specific phytoecological formation, while considering aspects of climate change and historical anthropisation.

“…The maximum growth series of some jaboticaba trees reached over 100 years of age (see Table 1) at DBH (1.30 m above ground level), in CH, PB, and VT. As these are locations with a high density of the species (> 40 trees ha -1 ), instead in Irati, other region of Paraná, the density was 1.56 jaboticaba trees ha -1 (Roik et al, 2019), this may indicate anthropogenic intervention in establishing these populations. The influence of indigenous people leading to more spread and density of useful and edible fruit species in Brazil has been recently demonstrated (Andrade et al, 2019;Caetano-Andrade et al, 2020;Cruz et al, 2020).…”

The jaboticaba tree (Plinia peruviana (Poir.) Govaerts) is a native Brazilian species, and its fruits are very popular in Brazil. The purpose of this study was to model the diameter growth, and determine the age of jaboticaba trees in four natural populations in Southwest of Paraná State, Brazil. The knowledge of the growth dynamics of this species is essential to assist management and conservation strategies and to discover when this species was established in the region. Core samples were collected to obtain complete growth series by measurement of annual growth rings. The series were crossdated, seven growth models were adjusted, and the best model for each site and a general model were selected using statistics rules. The time series spanned periods of ~75 to ~100 years, and growth ranged between 0.27 and 0.37 cm year-1. Chapman-Richards’ model showed better adherence for locations individually, and Monomolecular when grouped. Because to the age reached by the jaboticaba trees and the high density of this species in these natural populations, consequently named “jaboticabais”, it was inferred that there was an anthropogenic action in the dispersion and formation of the settlements through the indigenous and caboclos that inhabited the region before 1940. Also, this is the first work to register and verify the fusion of trunks for species of the Plinia genus using double piths found in samples, a feature that must be considered to avoid overestimating the age of jaboticaba trees based solely on measuring tree diameter.

“…Thus, the stands are in a temperate climate with mild summer, subtropical wet season, uniform precipitation and an average temperature of 22ºC, and average annual precipitation of 1605,7 mm with frequent frosts (IBGE, 2021;SIMEPAR, 2021). The native cover in the area is a Mixed Ombrophilous Montane Forest also known as Araucaria forest (Roik et al, 2019).…”

Several forestry procedures affect tree volume and shape, such as spacing, pruning, and thinning. Studying and understanding the effect of these operations on stand attributes are very important for forest management. This study aimed to evaluate volume, form factor, and taper for Pinus taeda trees stratified into diameter classes within two planting spacings. In addition, we aimed to evaluate the time spent to scale each tree, measured with a chronometer. Indirect scaling was performed using a Criterion RD 1000. Thirty trees were scaled on each planting spacing (3 m x 2 m and 4 m x 2 m), totaling 60 trees encompassing all diameter classes. Tree volume was calculated using the Smalian equation. Tree volume, form factor, and taper were calculated to each tree and evaluated by stand (independent t-test) and diameter class (variance analysis and Tukey test). The average scaling time was 4 minutes and 35 seconds, which decreased with practice (-24%). Form factor and taper differed with spacing and diameter class. Volume did not differ with spacing, but it did in the diameter classes. We concluded that indirect scaling is a practical method for tree volume assessment; higher planting density leads to more cylindrical stems with lower taper ratios in comparison with denser stands; and the fact that tree volume, form factor and taper differed among the diameter classes should be incorporated into studies of taper modeling.
