Abstract This paper presents a prototype Carbon Monitoring System (CMS) developed to produce regionally unbiased annual estimates of aboveground biomass (AGB). Our CMS employed bottom-up, two-step modeling strategy beginning with spatially and temporally biased sample: project datasets collected contributed by US Forest Service (USFS) other forestry stakeholders in 29 different areas the northwestern USA. Plot-level AGB served as response variable for predicting primarily from lidar metrics...
Numerous individual tree detection (ITD) methods have been developed for use with airborne laser scanning (ALS) data to provide tree-scale forest inventories across large spatial extents. Despite the growing number of methods, relatively few comparatively assessed using a single benchmark inventory validation dataset, limiting their operational application. In this study, we seven ITD representing three common approaches (point-cloud-based, raster-based, hybrid), coniferous stands diverse...
Digital image profiles of snowpack surfaces were acquired concurrently with 1‐cm resolution manual measurements. The measurements confirmed that unaltered digital images accurately represented a two‐dimensional roughness profile the surface. Roughness indices, such as random roughness, have been used to represent soil computed, and their utility for quantifying surface is illustrated. Variogram analysis was determine fractal dimension scale break. Surface characteristics function scale,...
Abstract On-the-ground sample-based forest inventory methods have been the standard practice for more than a century, however, remote sensing technologies such as airborne laser scanning (ALS) are providing wall-to-wall inventories based on individual tree measurements. In this study, we assess accuracy of height, diameter, and volume derived from field-cruising measurements three ALS data-derived in 1.1 ha stand using direct acquired felled trees log-scale Results show that although height...
Abstract In the semi‐arid western United States, water availability plays a defining role in land use. Soil moisture, vegetation, and microtopography are key variables hydrologic function of these ecosystems. Previous research has not addressed influence site‐specific aspect, or slope gradient on terracette soil moisture patterns rangelands. Therefore, objectives this study were to: (1) assess site vegetation cover, moisture; (2) conceptualize conditions at hillslope scale given morphology;...
Optimizing forest plantation management has become imperative due to increasing product demand, higher fertilization and costs, declining land availability, increased competition for use, the growing demands carbon sequestration. Precision forestry refers ability use data acquired with technology support decision-making process. LiDAR can be used assess metrics such as tree height, topographical position, soil surface attributes, their combined effects on individual growth. opens door...
Globally, remotely sensed data and, in particular, Airborne Laser Scanning (ALS), are being assessed by the forestry industry for their ability to acquire accurate forest inventories at an individual-tree level. This pilot study compares inventory derived using ForestView® biometrics analysis system traditional cruise measurements and felled tree 139 Pinus taeda sp. (loblolly pine) trees eastern Texas. The Individual Tree Detection (ITD) accuracy of was 97.1%. In terms height accuracy,...
Core Ideas Hoof impact on terracetted hillslopes affects bulk density and compaction between bench riser. Increased soil moisture is not plant available doesn't increase forage production. Greater water content benches due to shifts smaller pore sizes with compaction. Reduced vegetative cover root impedance results in greater content. Microtopographic features known as terracettes are found throughout semiarid rangelands. Their properties hydrologic function, however, virtually unknown. This...
N ationwide, we are losing our ability to maintain working forests as a result of defoliating and boring insects, disease, catastrophic wildfire, forestry infrastructure reductions, economic uncertainties-all exacerbated by an increasing urban population culturally removed from the natural environment.Nearly 10% 740 million acres forestlands within conterminous United States currently exhibit degraded health conditions (Krist et al. 2014).In part, this is historic wholesale fire suppression...
Abstract Terracettes are repeating step‐like microtopographic features roughly following the contours of hillslopes that often associated with livestock tracks. These common in many semi‐arid rangelands have been shown to alter soil moisture, slope stability, sediment transport, infiltration rates and coincident vegetation patterns. The spatial extent distribution terracettes is currently unknown therefore their landscape‐scale hydrological influence absent modelling land management decision...
