Growth of uneven-aged stands of loblolly pine, and Guldin and Baker () compared yields of even- and uneven-aged loblolly–shortleaf pine stands. More research is available on the uneven-aged management of other forest types. Several papers have reported on the eco-logical and economic implications of uneven-aged manage-Cited by: Get this from a library.

Growth model for uneven-aged loblolly pine stands: simulations and management implications. [Ching-Rong Lin; Joseph Buongiorno; Jeffrey P Prestemon; Kenneth Skog; United States.

The first, referred to as the single tree selection system, involves removal of individual trees across the stand, creating small openings in which species can naturally regenerate (Figure 3).

The objective of this Cooperative is to develop loblolly pine tree growth and stand development models sufficiently flexible to account for the effects of intensive cultural practices, with output sufficiently detailed to allow for analyses of a full range of utilization options.

Growth and Yield Models. Conversely, well-managed uneven-aged pine stands such as the Good and Poor Forty stands in Arkansas produce a new age cohort during every cutting cycle harvest or 2.

Looking at an three-aged forest from a diameter-class perspective, the difference between even and uneven-aged systems becomes clear. Uneven-aged forests typically have many small trees and very few big trees. Figure 5 presents the distinction. In this type of forest, young trees will be growing in the.

Results of this work (Platt et al. ) suggest that longleaf pine is a long-lived conifer that occurs in uneven aged/sized stands.

Old-growth popu­ lations appear to have been comprised of small patches of trees. Within patches, trees were File Size: KB. The Guo and Shelton model predicts that loblolly-shortleaf pine stands with basal that the best sites for pine growth are the worst sites and will also help forest managers meet the regeneration needs in their UEA pine stands.

In most cases, sawtimber-size loblolly pine trees provide the greatest economic benefit. Unmanaged loblolly pine stands can take up to 50 years to mature into sawtimber-size trees.

This forest structure provides needed or preferred so growth rates are typically lower with uneven-aged management than with even-aged management. Downloadable (with restrictions).

Forest carbon sequestration is regarded as a viable and cost effective option for reducing global greenhouse gas emissions. Several studies have analyzed the effects of joint management of carbon and timber under different even-aged forest management scenarios.

However, research specifically focused on the inclusion of carbon sequestration. Further research on model structures and statistically techniques used to quantify tree diameter growth in uneven-aged stands is warranted.

The fit models were evaluated using a data subset drawn from plots not included in model fitting; evaluation data also incorporated a different growth period (–).Cited by:   MacKinney and Chaiken () were the first to use multiple regression, with stand density as a predictor variable, to predict yield for loblolly pine trees.
