Document Summary
Access to education: predict the population growth rate of a nation with a large proportion or retired individual and an average fertility rate of < 2. Clear cutting and allowing trees to grow again. Tree plantation aka tree farm, commercial forest. Investing in replacing trees that are cut. Old growth has more richness and evenness. Greater resilience and susceptibility in old growth. Cutting down faster than they can be replenished. Roads are built to allow access into harvesting. Or if people want to live in that place. Once roads are put in, the land will be used differently. Changing the topography from forest to another type. Selecting trees that have the most economic value. Leaving trees to maintain ecosystem services for the biome. Costs more money to select some rather than cut all. Receding after clear cutting is not as successful as it would be in selective cutting. Less expensive than pulling selective trees from a forest.
