R.S. Moro & C.H Rocha 2010. A methodological proposal for restoration of forests in southern Brazil<br />

combined timber production <strong>and</strong> natural forest conservation. We propose a management option<br />

involving an initial st<strong>and</strong> density of 750 trees/ha with at least one thinning down to 250 trees/ha<br />

at 15 years of age.<br />
