The present work studies the yield of Araucaria angustifolia (Bert.) O. Ktze. stands in the region of Planalto Medio of Rio Grande do Sul state. It has been observed that the variety shows a great variation of production, represented by 7 site index with a spacing of 2 meters of height at the age reference of 40 years. Functions have been adjusted for estimating the height, diameter, form factor and number of trees per hectare. This analysis has allowed the confection of production tables which gives a clear idea of the situation of the remaining stands, thinning and total production.
