Abstract

The Atlantic Forest (AF) biome is considered a hotspot, presenting expressive biodiversity, endemism and being key to important ecosystem resources, such as environmental quality and carbon sequestration. However, the AF is currently highly threatened by urbanization and land conversion activities. Restoration strategies present themselves as potentials to convert these environmental problems in the biome. However, there are some knowledge gaps in restoration ecology that can be addressed by obtaining accurate and historical tree life data. Dendrochronology, as a discipline that studies the history of trees through the anatomical, physical and chemical parameters of the growth rings, provides key information about the growth rates, carbon fixation and nutrition of trees. Therefore, the present thesis project aims to prospect on the potential of applying dendrochronological techniques in restoration ecology studies in AF. The project comprises four main chapters that include (i) a literature review on the demands of restoration in the AF and how the discipline of dendrochronology can contribute to these issues; (ii) verification of the dendrochronological potential of twenty species used in restoration plantings; (iii) analyses considering different dendrochronological proxies for monitoring plantations under different conditions and (iv) for evaluating restoration methodologies with different objectives, in relation to environmental predictors. The project will provide a new point of view for restoration ecology, allowing pioneering and fundamental discussions to achieve global conservation goals in the AF.
