Performance of Guazuma ulmifolia Lam. in subtropical forest restoration

We evaluated the initial development of Guazuma ulmifolia Lam. in a reforestation experiment in the southwestern region of Parana State, Southern Brazil. In a 70 native tree species plantation (3x2 m spacing) data were collected biannually, up to 48 months, from 72 individuals of Guazuma ulmifolia. The species performance was evaluated regarding its survival (96%), root collar diameter (6.79 cm), total height (12.84 m), crown projection area (14.36 m(2)) and crown volume (49.86 m(3)). The species growth at the age of 48 months, associated to its high survival and sprouting rates, tells of excellent behavior in the region, and it could be highly recommended as a shading species for fast canopy fulfillment in forest restoration projects, especially in regions with frost occurrence.
