Effectiveness of competition indices for understanding growth in an overstocked stand

TL;DR: In this article, the authors used a stand of Araucaria angustifolia as a case study to develop an understanding of tree development over the long term, which will be useful in planning silvicultural intervention and in the management of new plantations of this species.

TL;DR: In this paper, a study was developed in order to model the growing space for Araucaria angustifolia (Bertol.) Kuntze trees, and a single equation was defined to estimate the crown diameter as a function of the diameter at breast height for this species.

TL;DR: In this article , the authors used 934 paired CW and DBH of Robinia pseudoacacia trees from 38 man-made gap forest sites (GPFs) of different sizes and 40 unmanaged Forest Service Forest Service (FSFS) sites (UMFs) in three counties with different climatic conditions in the Loess Plateau to evaluate potential deviations in CW estimation from existing crown allometry models.

TL;DR: Two modifications are proposed which make the index essentially independent of age, thus necessitating only one competition-grow th regression for each species on a given site and allowing comparisons between different stands, indicated that the correlation between competition and growth is optimal over a wide range of competition radii.

TL;DR: Des indices de competition dependants de la distance ont ete modifies pour modeliser la croissance d'arbres individuels de plantations et de peuplements homogenes de plantations au Portugal.

TL;DR: Five families of competition indices were evaluated and compared on the basis of simple correlation with loblolly pine individual tree growth and multiple correlation with growth in the presence of other tree and stand attributes to determine the best distance-dependent indices.
