Abstract
A method of managing timberland generally includes planting within a plot a first genetic tree crop of a first tree species that is selected for at least a first tree trait in a substantially linear pattern defining a first plurality of adjacent substantially linear beds at a first crop spacing and at a first row spacing between adjacent substantially linear beds. The method further includes interplanting a second genetic tree crop of the first tree species that is selected for at least a second tree trait in the first plurality of adjacent substantially linear beds at a second crop spacing that is shorter than the first crop spacing, such that adjacent substantially linear beds include trees of the first and second genetic tree crops.

A method of managing timberland comprising:
- (a) planting within a plot a first genetic tree crop of a first tree species that is selected for at least a first tree trait in a substantially linear pattern defining a first plurality of adjacent substantially linear beds at a first crop spacing and at a first row spacing between adjacent substantially linear beds, wherein the first tree trait is selected from the group consisting of limb arrangement, grain alignment, wood density, straightness, and stiffness, wherein the first genetic crop yields trees for high lumber value;
- and
- (b) interplanting a second genetic tree crop of the first tree species that is selected for at least a second tree trait in the first plurality of adjacent substantially linear beds at a second crop spacing that is shorter than the first crop spacing, such that adjacent substantially linear beds include trees of the first and second genetic tree crops, wherein the second tree trait is selected from the group consisting of limb arrangement, grain alignment, wood density, straightness, and stiffness, wherein the second tree trait is different in value from the first tree trait, wherein the second genetic tree crop is a relatively lower value genetic crop than the first genetic tree crop, and wherein the second genetic crop yields trees for fiber or cellulose value.
A method of managing timberland comprising:
- (a) planting within a plot a first genetic tree crop of a first tree species that is selected by a selection process for at least a first tree trait in a substantially linear pattern defining a first plurality of adjacent substantially linear beds at a first crop spacing and at a first row spacing between adjacent substantially linear beds, wherein the first tree trait is selected from the group consisting of limb arrangement, grain alignment, wood density, straightness, and stiffness, wherein the first genetic crop yields trees for high lumber value;
- and
- (b) interplanting a second genetic tree crop of the first tree species that is selected by a selection process for at least a second tree trait in the first plurality of adjacent substantially linear beds at a second crop spacing that is shorter than the first crop spacing, such that adjacent substantially linear beds include trees of the first and second genetic tree crops, wherein the second tree trait is selected from the group consisting of limb arrangement, grain alignment, wood density, straightness, and stiffness, wherein the second tree trait is different in value from the first tree trait, wherein the second genetic tree crop is a relatively lower value genetic crop than the first genetic tree crop, and wherein the second genetic crop yields trees for fiber or cellulose value.

- (a) planting within a plot a first genetic tree crop of a first tree species that is selected for at least a first tree trait in a substantially linear pattern defining a first plurality of adjacent substantially linear beds at a first crop spacing and at a first row spacing between adjacent substantially linear beds, wherein the first tree trait is selected from the group consisting of limb arrangement, grain alignment, wood density, straightness, and stiffness, wherein the first genetic crop yields trees for high lumber value;
- (b) interplanting a second genetic tree crop of the first tree species that is selected for at least a second tree trait in the first plurality of adjacent substantially linear beds at a second crop spacing that is shorter than the first crop spacing, such that adjacent substantially linear beds include trees of the first and second genetic tree crops, wherein the second tree trait is selected from the group consisting of limb arrangement, grain alignment, wood density, straightness, and stiffness, wherein the second tree trait is different in value from the first tree trait, and wherein the second genetic tree crop is a relatively lower value genetic crop than the first genetic tree crop, wherein the second genetic crop yields trees for fiber or cellulose value;
- (c) at least partially harvesting the first and second genetic tree crops;
- and
- (d) planting a first genetic tree crop in a second plurality of substantially linear beds at the first crop spacing in substantially parallel rows approximately midway between the first row spacing of the first plurality of adjacent substantially linear beds within the plot, and interplanting a second genetic tree crop in the second plurality of substantially linear pattern beds at a second crop spacing that is shorter than the first crop spacing.
