Item Aspectos do crescimento da Baraúna (Schinopsis brasiliensis Engel.), em diferentes contextos de intervenções antrópicas, na comunidade da Mata Redonda em Triunfo – PE.(2022-05-27) Santos, Natália Alves; Barros Júnior, Genival; http://lattes.cnpq.br/4379675294862211; http://lattes.cnpq.br/4530134000429562The Caatinga vegetation has a very peculiar characteristic, which makes it unique and, unfortunately, due to anthropic actions, a considerable portion of this biome is in extinction and another portion is threatened with extinction. Among the endangered plant species is the Baraúna (Schinopsis brasiliensis Engl.), one of the most important trees in the Caatinga, considered a noble tree due to the characteristics present in its wood. Given this situation, research actions aimed at preventing the extinction of the Baraúna species are shown to be of great importance for the preservation of biodiversity in the Caatinga Biome. However, there are still few studies aimed at rescuing and protecting the dynamics of this important species in the Caatinga vegetation. Thus, the objective of the present work was to study the initial behavior and to relate the growth rates of Baraúna plants introduced in areas under different impacts arising from agricultural management over time in environmental conditions of high-altitude swamp. 10 The experiment was carried out in a Random Block Design - DBC, in an 11 x 3 arrangement (11 baraúna plants in 3 different areas of human intervention) area 1- degraded soil; area 2- arable soil; area 3- agroforestry system, carried out from October 2021 to March 2022. Soils were collected for analysis, rainfall data, luminosity data, soil cover and monthly biometric readings. In area 1, the soil was classified as sandy clay, compacted, low rate of living and dead cover, accentuated presence of erosive processes, high presence of luminosity and average growth of baraúnas when compared to the other areas; area 2- clay soil, compacted, high presence of living cover, medium presence of mulch, presence of erosive processes, high level of luminosity and it was the area in which the plants showed the highest growth in terms of stem diameter as in vertical growth; and in area 3 soil classified as sandy clay loam, not compacted, high index of living and dead cover, punctual erosion processes, low luminosity and slow growth of baraúnas. The baraúna plants are demanding in light, requiring full exposure of the canopy of their canopy to solar radiation to ensure a satisfactory development of the individuals of their species. The reintroduction of the species Schinopsis brasiliensis in the ecosystem of highland swamps is recommended due to its ecological, environmental and anthropological importance for the enrichment of local biodiversity.
