Fig. 4From: Effects of nurse shrubs and tree shelters on the survival and growth of two Austrocedrus chilensis seedling types in a forest restoration trial in semiarid Patagonia, ArgentinaInitial seedling height (2006, average ± 1 standard error) and after 5 years (2011, average ± 1 standard error) by cover type (C1, C2, and C3 correspond to nurse shrub, tree shelter, and control, respectively) and seedling type (S1 and S2 correspond to seedling types 1 and 2, respectively), respectively. Different lowercase letters indicate statistically significant differences (p < 0.05) in 2006; different capital letters indicate statistically significant differences (p < 0.05) in 2011Back to article page
