Abstract: The Caatinga (dryland) vegetation of northeastern Brazil has become highly anthropized while still poorly studied, with little research evaluating its potential for natural regeneration. This study sought to compare the compositions and structures of the shrub-arboreal components of two Caatinga areas with different histories of anthropic disturbance in the Negreiros National Forest, Pernambuco State, Brazil. Twelve 4 × 50 m plots were established in each area, sampling all individuals ≥ 1 m tall with stem dia… Show more

“…5). Consequently, we conclude that the BSA region is completely impacted by anthropogenic activities although at different levels depending on historical uses (Monteiro & Kurtz 2020). This is not surprising as the poor rural population had to count on natural resources for their survival, the most common activities being wood harvesting, hunting, slash and burn agriculture, and deforestation to create pasture for cattle and goats.…”

“…When we included herbaceous species, other families became floristically important, for instance, Asteraceae and Convolvulaceae (Araújo et al 2005). However, these authors reported that ratios between herbaceous and tree species and the dominant species can vary considerably from one site to another (Moro et al 2015;Monteiro & Kurtz 2020). Additionally, even areas that are considered as well-conserved show signs of past use (Guedes et al 2012).…”

“…A elevada heterogeneidade edafoclimática do semiárido modelou sua vegetação predominante, a floresta tropical sazonalmente seca, a qual exibe pelo menos 13 fisionomias diferentes, as caatingas. Por esse motivo, as caatingas se apresentam tanto como áreas abertas, dominadas por espécies arbustivas e cactáceas, como também florestas com espécies arbóreas de pequeno e médio porte, arbustos e herbáceas, que variam em grau de conservação de acordo com o histórico de uso e ocupação humana (Queiroz et al, 2017;Monteiro & Kurtz, 2020). Diferentemente das espécies vegetais de outros biomas brasileiros, as espécies da Caatinga desenvolveram adaptações únicas para sobreviver às condições climáticas do semiárido (Marques et al 2020), como troncos retorcidos, folhas pequenas, presença de espinhos, acúmulo de água nos tecidos (espécies suculentas), diferentes graus de sensibilidade à seca em espécies arbóreas, respostas fisiológicas rápidas em herbáceas, que crescem e florescem após os primeiros eventos chuvosos (Queiroz et al, 2009;Mesquita et al, 2018).…”
