Slope measurements are often necessary for assessing features and processes within the natural environment. Land managers often use handheld equipment rather than more complicated surveying equipment in order to measure slopes and to conduct field work efficiently. One type of handheld device used to measure slope is a laser clinometer. In order to determine the accuracy and user error associated with this type of clinometer, slope measurements were taken at multiple locations using two types of equipment: 1) a Haglof Sweden Vertex III Hypsometer with a laser clinometer function and 2) a Topcon GTS-603/AF electronic survey total station which can …
Modeling Loblolly Pine Aboveground Live Biomass In A Mature Pine-Hardwood Stand: A Cautionary Tale, D. C. Bragg
Modeling Loblolly Pine Aboveground Live Biomass In A Mature Pine-Hardwood Stand: A Cautionary Tale, D. C. Bragg
Journal of the Arkansas Academy of Science
Carbon sequestration in forests is a growing area of interest for researchers and land managers. Calculating the quantity of carbon stored in forest biomass seems to be a straightforward task, but it is highly dependent on the function(s) used to construct the stand. For instance, there are a number of possible equations to predict aboveground live biomass for loblolly pine (Pinus taeda) growing in southeastern Arkansas. Depending on stem diameter at breast height (DBH), biomass varied considerably between four different prediction systems for loblolly pine. According to the tested models, individual tree oven-dry biomass for a 50 cm DBH loblolly …
