Table 2. Landscape Area Prescription Elements
NOTE: Thinning entries were designed to maintain stocking of species according to their levels in the stand at the time of entry. Shade intolerant species may not thrive under 50% canopy retention, so it may not make up 40% of the stocking at the time of thinning. However, retention trees are intended to be patchy, and should allow regeneration of both shade-intolerant and shade-tolerant species.
