“…It is considered a moderately shade-tolerant species and is used for timber (Mostacedo & Fredericksen 1999). The tree species P. excelsa has a wide distribution in the tropical and subtropical forests of South America (Názaro et al 2021). It has a height of 10-20 m and a DBH of up to 60 cm.…”

“…Unplanned selective logging focused on the best individuals of economically valuable tree species in the Piedmont Forest caused a reduction between 1975 and 2000 of c. 30% in the volume of the main commercial timber tree species and some of these species are now no longer commercially viable (Minetti et al 2009, Politi & Rivera 2019. Currently, the conservation status of 8 of 12 valuable timber tree species in the Piedmont Forest is poor (<50% occurrence in sampled plots, density of large trees <1 large tree/ha, density of regeneration <30 seedlings/ha; Názaro et al 2021). Projections of the community climate model of the National Center for Atmospheric Research predict a retraction and displacement of the potential distribution of adults of six timber tree species of the Piedmont Forest to higher altitudes (Pacheco et al 2010).…”

Summary The distribution of regeneration makes it possible to assess whether populations of tree species will maintain or change their distributions. For Neotropical dry forests there is little information on the potential changes in the distribution of tree species. Here, we evaluate the potential distributions of adults and seedlings of eight timber tree species of the Piedmont Forest of north-western Argentina by recording the presence of seedlings and adults in plots and modelling with MaxEnt software using three bioclimatic variables. The potential distribution areas of seedlings and adults and the percentage of overlap of seedlings with respect to adults were calculated. The potential distribution for adults was 694 457 ± 62 535 ha, and this figure was 656 564 ± 194 769 ha for seedlings. The potential distribution of seedlings of Calycophyllum multiflorum covered the smallest area (184 496 ha) and had the least overlap with the adults (18%). The difference in the overlap of the potential distribution areas between adults and seedlings suggests that there could be changes in the future distribution of this tree species and C. multiflorum should therefore be the focus of conservation strategies so that the species can follow its bioclimatic niche as the climate changes.
