A method of managing timberland to optimize the plot growth rate for a plot including a softwood tree crop and an energy crop generally includes planting a softwood tree crop in adjacent first and second rows, wherein the softwood tree crop has a tree spacing between adjacent trees and a row spacing between the first and second rows, planting an energy crop in the row spacing, wherein the energy crop is a regenerating lignocellulosic energy crop, and periodically measuring the plot growth of the softwood tree crop and the energy crop. A method of managing timberland to optimize the total plot volume of a softwood tree crop and an energy crop generally includes periodically measuring the total plot volume of the softwood tree crop and the energy crop.

Methods of managing timberland

A method of managing timberland to optimize the combined revenue of a softwood tree crop and an energy crop generally includes planting a softwood tree crop in adjacent first and second rows, wherein the softwood tree crop has a tree spacing between adjacent trees and a row spacing in the range of about 15 to about 25 feet between the first and second rows, planting an energy crop in the row spacing, wherein the energy crop is a regenerating lignocellulosic energy crop, and periodically harvesting the energy crop. Methods of managing timberland to optimize the plot growth rate for a plot including a softwood tree crop and an energy crop, and to optimize the total plot volume of a softwood tree crop and an energy crop are also provided.

A method of managing timberland generally includes planting a softwood tree crop in first and second rows, wherein the tree crop has a tree spacing between adjacent trees and a row spacing between the first and second rows. The method further includes planting an energy crop in the row spacing, wherein the energy crop is a regenerating lignocellulosic energy crop. The method further includes periodically harvesting the energy crop for a predetermined number of harvests.

A method of managing timberland generally includes planting a first tree crop in first and second rows each having tree spacing between adjacent trees and a first row spacing between the first and second rows. The method further includes planting a first planting of a first energy crop in the first row spacing. The method further includes planting a second tree crop in a third row having tree spacing between adjacent trees and a second row spacing between the second and third rows, wherein the second row spacing is different from the first row spacing. The method further includes planting a first planting of a second energy crop in the second row spacing.
