Sustainable forest management

An excellent soil-enriching understory in pine forests, sustainable forest management incorporates more mixed plantings of proven efficiency, as opposed to monosylviculture. A study presented in 1997 has evaluated positively the potential increase in productivity with mixed stands and plantations, compared to plots of only one species. The relative yield total values of the mixed plantings steadily increase with time. C. sativa responds well to competitive pressure from Pseudotsuga menziesii, the latter also showing a higher productivity. C. dentata seedlings in Ohio reforestation efforts are best achieved by planting them in places with little or no arboreous land cover, because of the need for light.
