Density of Araucaria angustifolia wood from overstocked stand
Curto, Rafaella De Angeli; Mattos, Patricia Póvoa de; Braz, Evaldo Muñoz; Netto, Sylvio Pellico; Zachow, RandolfThe aim of this work was to evaluate the radial and longitudinal variations of wood specific gravity in an overstocked stand of Araucaria angustifolia, with 65 years. The stand was located in the National Forest of Açungui, Campo Largo, Parana State, Brazil, with thinning recorded between 1970 and 1980, without subsequent thinnings. We selected three trees for each diameter class: 10-30 cm, 30-50 cm and 50-70 c...

No. of bitstreams: 0 Previous issue date: 2019-10-01; The aim of this study was to explore methods to: (1) enhance coarse-scale estimates of wood volume from National Forest Inventories (NFIs) data and (2) map them at finer scales. The 'standard' coarse-scale estimation extrapolates wood volume from clusters to the grid cell they represent, using the clust...
