CCA analysis for the measured biometric and water potential variables of the regeneration during the growing season (a November, b January, and c March). Plots were classified according to the different treatments: AR = aggregated retention, DR = dispersed retention, RT = under the influence area of remnant overstorey trees, D = under woody debris, and R = over secondary roads. Environmental explicatory variables were volumetric soil water content (VSW) (percent), crown and debris cover (CC) (percent), global radiation (GR) (watts per square meter), soil acidity (pH), cation exchange capacity (CEC) (milliequivalents per 100 g), soil bulk density (SD) (grams per cubic centimeter), and nutrient soil content of organic carbon (C) (milligrams per cubic centimeter), total nitrogen (N) (milligrams per cubic centimeter), phosphorous (P) (milligrams per cubic centimeter), potassium (K) (milligrams per cubic centimeter), and magnesium (Mg) (milligrams per cubic centimeter)
