Allometric equations for determining volume and biomass of Acer monspessulanum L. subsp. cinerascens multi-stemmed trees
Due to the importance of Acer monspessulanum in Iranian mountain forests, a study was carried out to reliably estimate its woody biomass and growing volume via allometric equations. Four transects, five trees in each were chosen randomly. The characteristics of standing trees including: diameter at root collar, height, number of stems and crown width were measured, then trees were finally cut d...
متن کاملStress Response of Dominant Forest Tree Species South of the Caspian Sea in Relation to Soil from Coast to Upland
Distribution and growth of plant species is affected by many factors including abiotic (topography, altitude and soil) and biotic (root symbiosis) factors. In light of global warming, recent findings advocate microhabitats and micro-conditions of the root zone and canopy ambiance as determining factors in sustaining of plant populations. Although, occurrence of ectomycorrhizal (ECM) and non...
متن کاملEffects of non-native grass invasion on aboveground carbon pools and tree population structure in a tropical dry forest of Hawaii
Hawaiian tropical dry forests are a unique and highly endangered ecosystem. Remaining fragments are heavily impacted by invasive plant species, particularly the perennial bunchgrass Pennisetum setaceum (Forssk.) Chiov. (fountain grass). Little is known about the impact of invasive species on carbon cycling in terrestrial ecosystems. Biomass estimates are a critical first step in understanding t...
متن کاملEstimation of Tree Biomass at Individual tree, Sample plot and Hybrid Level using Drone Images
Two-dimensional image conversion algorithms to 3D data create the hope that the structural properties of trees can be extracted through these images. In this study, the accuracy of biomass estimation in tree, plot, and hybrid levels using UAVs images was investigated. In 34.8 ha of Sisangan Forest Park, using a quadcopter, 854 images from an altitude of 100 meters above ground were acquired. SF...
متن کاملAllometric biomass equations for 12 tree species in coniferous and broadleaved mixed forests, Northeastern China
Understanding forest carbon budget and dynamics for sustainable resource management and ecosystem functions requires quantification of above- and below-ground biomass at individual tree species and stand levels. In this study, a total of 122 trees (9-12 per species) were destructively sampled to determine above- and below-ground biomass of 12 tree species (Acer mandshuricum, Acer mono, Betula p...
