LiDAR remote sensing of forest structure
  • LiDAR remote sensing of forest structure
  • Bibliography ; Biogeography ; Biomass ; Ecosystem ; Forest ; Photogrammetry ; Remote sensing ; Research technique ; Spatial distribution
  • Laser altimetry or Light Detection And Ranging (LiDAR) technology provides horizontal and vertical information at high spatial resolutions and vertical accuracies. Forest attributes such as canopy height can be directly retrieved from LiDAR data
  • . Direct retrieval of canopy height provides opportunities to model above-ground biomass and canopy volume. Access to the vertical nature of forest ecosystems also offers new opportunities for enhanced forest monitoring, management and planning.

Potential impact of ozone on coniferous forests of the interior southwestern United States
  • Potential impact of ozone on coniferous forests of the interior southwestern United States
  • Atmospheric pollution ; Climate ; Conifer ; Forest ; Global change ; Impact ; Model ; Ozone ; United States of America ; Vegetation dynamics
  • Through a review of literature pertaining to most aspects of ozone and its impact on forest health, this article provides insights on the ozone/forest dynamic within coniferous forests of the interior Southwest. Is is suggested that ozone absorption
  • in southwestern coniferous forests may equal that in southern California, owing to the long-distance transport of atmospheric pollutants into the interior Southwest and the presence of the North American monsoon. It is suggested a need for future research on ozone
  • exposure levels and the ozone sensitivities of conifer species and varieties in southwestern coniferous forests.

Stress hydrique estival et incendies de forêt dans le nord-ouest de la Tunisie
  • Bioclimatology ; Forest ; Forest fire ; Summer ; Tunisia ; Water deficit ; Years 1990-99
  • More than half of the forests of Tunisia are in the North-West of the country where forest fires happen mainly during summer. The variations of fires (numbers and burnt surfaces) have been compared from 1990 to 2001 with the variability

Sediment flux and compaction trends on off-road vehicle (ORV) and other trails in an Appalachian forest setting
  • Sediment flux and compaction trends on off-road vehicle (ORV) and other trails in an Appalachian forest setting
  • Environmental management ; Erosion rate ; Forest ; Impact ; Land use ; Ohio ; Recreation behaviour ; Soil erosion ; Soil properties ; United States of America
  • This research investigates the impact of off-road vehicles (ORVs) on sediment dynamics and compaction in the forested hillslope terrain of southeastern Ohio. A dense network of ground-height change, penetrometer resistance, and penetrometer depth
  • measurements was collected from trails and trail-adjacent forest land at 4 ORV and, for comparison, 2 non-ORV rail study sites (hiking, horse-riding). Repeat measurements were made at the height and the end of the ORV season, and near the end of the off-season
