This research characterised measures of aboveground biomass isolated Irvingia gaboneensis stands within Isoko South Local Government Area’s rainforest, Nigeria. The design the study was based on quasi experimental approach. region divided into 10 existing major communities using stratified sampling technique. From each community, an I. stand chosen while adjacent mature rainforest served as con...

Forests have been proposed as a means of reducing atmospheric carbon dioxide levels due to their ability to store carbon as biomass. To quantify the amount of atmospheric carbon sequestered by forests, biomass and density estimates are often needed. This study develops, implements, and tests an individual tree-based algorithm for obtaining forest density and biomass using orthophotographs and s...

BACKGROUND Estimates of live-tree carbon stores are influenced by numerous uncertainties. One of them is model-selection uncertainty: one has to choose among multiple empirical equations and conversion factors that can be plausibly justified as locally applicable to calculate the carbon store from inventory measurements such as tree height and diameter at breast height (DBH). Here we quantify t...

NĚMEC P. 2015. Comparison of modern forest inventory method with the common method for management of tropical rainforest in the Peruvian Amazon. Electronic devices consisting of field computer, laser rangefinder, electronic compass and global positioning system unit were used for data collection in the tropical rainforest of the Peruvian Amazon with the objective of comparing forest inventory m...

This paper evaluated the feasibility of a terrestrial point cloud generated utilizing an uncalibrated hand-held consumer camera at a plot level and measuring the plot at an individual-tree level. Individual tree stems in the plot were detected and modeled from the image-based point cloud, and the diameter-at-breast-height (DBH) of each tree was estimated. The detected-results were compared with...

To investigate the effect of surrounding tree density and topography site host on abundance, species richness, diversity epiphytic orchids, 32 trees Schima wallichii were chosen randomly orchids counted identified. Within a circle radius 20m from each tree, with diameter at breast height (DBH) greater than 20 cm had their name DBH recorded. In addition, angle direction slope which stood measure...

In this research, biodiversity was investigated in the species diversity level. The objective of this research was to study of Norway Maple (Acer platanoides L.) dispersion and biodiversity of associated woody species in the Shafaroud forests, Gilan (IRAN). In this regard, a 0.5 ha lozenge sample plot was selected with considering presence of Norway Maple in each site. In each plot, geographic ...

Methods for accurately measuring biophysical parameters are a key component for quantitative evaluation regarding to various forest applications. Conventional in situ measurements of these parameters take time and expense, encountering difficultness at locations with heterogeneous microtopography. To obtain precise biophysical data in such situations, we deployed an unmanned aerial system (UAS)...

We characterized Indiana bat (Myotis sodal is ) roost ing habi ta t a t three maternity colony sites in western North Carolina and eastern Tennessee. Using radio telemetry, we tracked six bats a total of 40 bat days (range 4-9 days/ bat). In 1999, we located a primary roost in an eastern hemlock (Tsuga canadensis) snag (109 cm DBH) in the Nantahala National Forest , NC. In 2000, we located a pr...

Forest measurements using conventional methods may not capture all the important information required to properly characterize forest structure. The objective of this study was develop a low-cost alternative method for inventory and characterization structure handheld LiDAR technology. Three-dimensional (3D) maps trees were obtained an iPad Pro with sensor. Freely-available software programs, i...
