An analogy that comes to mind is aquaculture. In aquaculture the goal is to produce say for instance oysters, salmon or shrimp for human consumption. The typical goal of aquaculture is not to improve the marine ecology, it is to produce optimal food products efficiently. Historically silviculture has followed a similar model. Nowadays silviculture techniques may be used for example to do ecological restoration, but I think the practice of silviculture is strongly based in the realm of timber production, either sustainable or not. -Andrew
