This is an illegal but lucrative business, since the income of the trappers from selling these birds is very high. When applying the crop-tree release method, leave crop trees at least 20 to 25 feet apart.

If crop trees are scarce or unevenly distributed, leave two trees as close as 10 feet but treat them as one tree when thinning. Remove trees with crowns that encroach on the crop trees (Figure ).

On a cleared area at m (1, ft) elevation, 1-year-old seedlings ranged from. The age structure and growth patterns of 53 young conifer-hardwood stands on upland, south-facing sites of interior Alaska were analyzed to determine the length of time for stand establishment after disturbance, the composition of early-successional stands compared to existing stands, and the potential for late-successional stands dominated by.

In his book Silviculture in the Tropics, Lamprecht () cites Leibundgut: “Today, silviculture considers the forest as ecosystem.

It aims at regulating all life processes in an ecologically stable forest and organizing its establishment and regeneration in a way that all needs related to forests are fulfilled best possible and sustainably.
