Forest restoration plantations are important tools in the recovery and maintenance of degraded ecosystems, due to the various environmental services that forest cover offers. Currently, Brazil has a great demand for the recovery of degraded areas and environmental adaptation. However, this great demand does not take into account the influence of this type of planting on the water regime of water bodies, which involve several species with different growth dynamics and successional relationships. Thus, knowledge of the physiological behavior of forest species in the face of different conditions of biotic and abiotic stresses helps in the development of management methodologies and more assertive species recommendation, essential for the initial establishment of planting. The study raises the following questions: (1) do species with different growth rates and level of ecological succession have different rates of water consumption? (2) in places with greater water availability, do these species tend to have a greater consumption in relation to places with less water availability? Within this context, the study aims to evaluate the efficiency in water use and physiological behavior of three species (two native and one exotic), with different growth characteristics, in regions with different water availability. To measure this consumption, the following will be evaluated: the photosynthesis rate, stomatal conductance in relation to the vapor pressure deficit (VPD), water status of plants and stomatal characterization of the same.
