Determine the most suitable Allometric equations for Estimating Above-ground Biomass of the Juniperus excelsa
Today, modeling and determination of allometric equations of forest trees, especially Junipers trees, are very important for determination of biological status and carbon storage capacity of forest species. The aim of this study was to determine the most suitable allometric equations for estimating the biomass of leaf, sub branch, main branch, trunk, and biomass of total Juniperus excelsa tr...
متن کاملRemote Sensing of Above-Ground Biomass
Accurate measurement and mapping of biomass is a critical component of carbon stock quantification, climate change impact assessment, suitability and location of bio-energy processing plants, assessing fuel for forest fires, and assessing merchandisable timber. While above-ground biomass includes both live and dead plant material, most of the recent research effort on biomass estimation has foc...
متن کاملThe effect of small gaps in California annual grassland on above-ground biomass production
Small gaps and clumped species distributions are common in grasslands. In California annual grasslands, patches of Lolium multi ̄orum Lam. and Bromus hordeaceus L. are often separated by gaps. These gaps potentially limit the productivity and associated resource use of these grasslands. The effect that differences in spatial aggregation, gap distribution and species mixing on 20-cmdiameter plots...
متن کاملAbove-ground biomass and structure of 260 African tropical forests
We report above-ground biomass (AGB), basal area, stem density and wood mass density estimates from 260 sample plots (mean size: 1.2 ha) in intact closed-canopy tropical forests across 12 African countries. Mean AGB is 395.7 Mg dry mass ha⁻¹ (95% CI: 14.3), substantially higher than Amazonian values, with the Congo Basin and contiguous forest region attaining AGB values (429 Mg ha⁻¹) similar to...
متن کاملCost and Utilization of above Ground Biomass in Thinning
Billy Watson and Bryce Stokes ABSTRACT: The cost and utilization were compared for a thinning operation removing the stems as roundwood with a flail chipper operationThe flail chipper operation recovered an additional 4.2 tons of acceptable chips per acre which resulted in a higher return to the site. There was little difference in the cost of acceptable chips delivered to the digester between ...
