What does the growth/harvest ratio measure?

  1. The economic return of timber sales

  2. Timber growth in relation to harvest

  3. The environmental impact of logging

  4. The size of the timber market

The correct answer is: Timber growth in relation to harvest

The growth/harvest ratio measures the relationship between timber growth and the amount of timber harvested over a specific period. This ratio is crucial for understanding the sustainability of forest management practices. A ratio greater than one indicates that growth exceeds harvest, suggesting that the forest is expanding and can be sustainably managed over time. Conversely, a ratio less than one indicates that the harvest exceeds growth, which can lead to depletion of forest resources if not managed carefully. Therefore, this metric is essential for foresters in making decisions about timber sales, ensuring that harvesting does not jeopardize the future of the forest ecosystems. In contrast, the other options focus on different aspects of forestry, such as economic returns, environmental impacts, and market size, which do not specifically address the quantitative relationship between timber growth and harvest levels.
