Numerous studies have used various types of remotely sensed data to estimate forest biomass-related parameters such as basal area, volume, biomass, stocking etc. Some sensors have high spectral resolution such as ASTER or MODIS, but low spatial resolution whereas others have high spatial resolution, but low spectral information, such as IKONOS and QuickBird. Digital Globe’s WorldView-2 provides...

Slash,lobloUy,lonaieaf, and shortleafpines in northern Louisiana were examined for differences in moisture content (MC) and basic specific gravity (SO) of wood and bark in the complete tree, root, stem, and branches and differences in diameter at breast height (dbh), total height, and taproot length of trees in even-aged plantations under identical site conditions, planting densities, and manag...

Black locust is one of the most commonly planted exotic tree species in world. It has a crucial role mitigating negative effects climate change. Its increment analyses have key forest planning. Increment added to wood stock over and again, only this continuous replenishment makes sustainable management possible. This study presents results analysis periodic annual (PAI) by diameter (dbh) volume...

In temperate and subtropical climates, Populus deltoides is an important poplar species. To analyze the stability, adaptability, high yield of P. hybrid genotypes in East China, 38 were screened at three experimental sites Shandong Province, coefficients variation genetic characteristics 5-year growth examined using BLUP-GGE. Results showed that all variance higher for diameter breast height (D...

We used lightweight terrestrial laser scanning (TLS) to detect over 3000 stems per hectare across a 12-ha permanent forest plot in French Guiana, 81% of them < 10 cm trunk diameter. This method retrieved 85% the trees classic inventory. Finally, TLS revealed that stem positions inventory had geolocation errors up 6 m. Accurate position mapping tropical rainforest is crucial for baseline studies...

This study investigated a typical secondary Betula platyphylla forest in the Ziwuling Mountains, Loess Plateau, China. In the sample plot, the DBH (diameter at breast height) class structure of B. platyphylla was bimodal. Individuals with small and large DBH values were abundant. The DBH structures of Quercus wutaishanica and Pinus tabulaeformis were close to that of the logistic model, thus su...

Dalbergia tonkinensis is being promoted in Vietnam for the future supply of prized wood furniture and chemical extraction. Expansion plantation area requires a reliable source quality seed. This study evaluates field performance progeny from mature mother trees natural forests urban environments. Trials were established Tan Son Doan Hung districts Phu Tho province assessed 3 years later. There ...

Pterocarpus angolensis DC and Bobgunnia madagascariensis (Desv.) J. H. Kirkbr. &amp; Wiersema are two hardwood species found in Miombo woodland. Crown size, being closely related to the photosynthetic capacity of a tree, is an important parameter studies growth individual trees. In this sense, present study aimed morphometric relationships P. B. as resource describe features these species. Data...

We present a novel approach to generating regional scale aboveground biomass estimates for tree species of the Lake Tahoe Basin using hyperspatial (<1 m ground resolution) remote sensing imagery. Tree crown shadows were identified and delineated as individual polygons. The area of shadowed vegetation for each tree was related to two tree structural parameters, diameter-at-breast height (DBH) an...

directional felling of trees plays a key role in reducing of damages to forest residual trees and can also facilitate skidding. the aim of this study was presents a practical linear model for estimation of tree falling direction error in an uneven-aged mixed stand in northern forests of iran. to conduct the study a number of 95 trees of four species fagus orientalis lipsky, carpinus betulus l.,...
