Over exploitation can lead to the exceeding of the practical sustained yield, i.e. more water is taken out than can be replenished.

The current harvesting rate for old growth is based on achieving sustained yield.

Healthy, well selected seedlings are necessary for early and sustained high yield.

In neither case, though, was the resource managed so as to ensure a sustained yield.

As a result, most management techniques in North American forests approach, rather than achieve, a situation of sustained yield.

Multiple use implies a sustained yield of outdoor recreation, range, timber, watershed, and wildlife and fish values.

However, the concept of sustainability is much broader than the concepts of sustained yield of welfare, resources, or profit margins.

The industry agreed to the idea of sustained yield, in which trees are cut no faster than they can be replenished.

He said the maximum sustained yield for Nassau was 340 million gallons a day.

These three laws dealt with timber sales, regulations and sustained yield, and rights-of-way.
