Studies with Curatella americana L wood are justified due to scarce information about this species. In context, we collected samples from six trees (ages varied between 30-40 years old) planted in Selvíria (MS- Brazil). Our objective was verify longitudinal variation of basic density and anatomy. From each sampled tree, 5 cm thick discs were removed, at three different heights: base the trunk (...

Recently, a new method on tree stem isolation using volumetric image data from terrestrial laser scans (TLS) has been introduced by the same authors. The method transfers TLS data into a voxel grid data structure and isolates the tree stems from the overall forest vegetation. While the stem detection method yields on a three dimensional localisation of the tree stems, the present study introduc...

For maintaining of Zagros forests role in wild life, water and soil conservation, the suitable solutions and methods for assessing the existing conditions and planning for management of this forests should be given. To detection of suitable sampling method to study tree Diameter at Breath Height in the northern Zagros forest, Blake forest, in Baneeh region, Kurdistan province, and west of Iran ...

Traditional forest inventories are based on field surveys of established sample plots, which involve measurements individual trees within a plot and the selection proper allometric equations for tree volume calculation. Thus, accurate properly selected two crucial factors providing high-quality volumes. One key problem is difficulty in accurately acquiring height data, resulting high uncertaint...

Maquira coriacea is a commercial tree species growing throughout the Amazon flood plain forests. Densities up to 14/ha of individuals, >10 cm diameter at breast height (DBH) were observed, corresponding to a basal area of 2 m/ha and a volume of 38 m/ha. The primary period of fruiting coincided with the annual flooding, but fruits were also produced in other parts of the year. Seedlings with den...

Abstract: The objective of this work was to assess the genetic variability Araucaria cunninghamii in a provenance test and estimate gains its wood production, based on different selection intensities. trial established Luís Antônio, state São Paulo, Brazil, using open-pollinated seed from Queensland, Australia. experimental design used randomized complete block with six replicates, four plants ...

The aim was to investigate the relations between diameter at breast height and maximum crown diameter, tree height and other possible independent variables available in stand databases. Altogether 76 models for estimating stem diameter at breast height and 60 models for tree age were formulated using height and maximum crown diameter as independent variables. These types of models can be utiliz...

Swedish owners of poplar stands are interested in both the wood quality and the use of poplars that are soon to be harvested. An important concern is the frequency of false heartwood (FHW) in the stems. We have presented an overview of the factors causing discolored wood as well as the industrial use and quality of the end products. We have studied poplar stems growing at 22 sites in Sweden bet...
