Canopy height damage by Typhoon Songda in Northern Hokkaido, Japan, in 2004

open access: yesEnvironmental Research: Ecology
The increasing need for the risk assessment of disastrous wind disturbance, especially by tropical cyclones (TCs), has been emphasized because the number of intense TCs is projected to increase due to global warming, though there are some discrepancies ...

Species level mapping of forest canopy height in Nepal using GEDI with Sentinel-1 and Sentinel-2

open access: yesFrontiers in Remote Sensing
Forest canopy height mapping is critical for mapping and modeling bio-geophysical and ecological factors, including forest aboveground biomass, carbon reserves, forest carbon emissions, habitat diversity, forest degradation, and restoration success.

Mapping Forest Canopy Height in Mountainous Areas Using ZiYuan-3 Stereo Images and Landsat Data

open access: yesForests, 2019
Forest canopy height is an important parameter for studying biodiversity and the carbon cycle. A variety of techniques for mapping forest height using remote sensing data have been successfully developed in recent years.

Annual–Perennial Forage Mixtures Improve Forage Productivity and Soil Quality in Patchily Degraded Cultivated Pastures Under Grazing Management

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Patchy degradation of cultivated pastures under long‐term grazing is a serious issue limiting grassland productivity. The use of annual and perennial legume–grass mixtures, which offer complementary functional advantages, may provide a practical reseeding‐based approach for improving patchily degraded cultivated pastures; however, limited ...

Predictions of Tropical Forest Biomass and Biomass Growth Based on Stand Height or Canopy Area Are Improved by Landsat-Scale Phenology across Puerto Rico and the U.S. Virgin Islands

open access: yesRemote Sensing, 2017
Remotely-sensed estimates of forest biomass are usually based on various measurements of canopy height, area, volume or texture, as derived from LiDAR, radar or fine spatial resolution imagery. These measurements are then calibrated to estimates of stand

Estimation of Forest Canopy Height Over Mountainous Areas Using Satellite Lidar

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2014
The full waveform data of the large-footprint Geoscience Laser Altimeter System (GLAS) on the Ice, Cloud, and land Elevation Satellite, together with airborne light detection and ranging (lidar) data, were employed to retrieve the basal-area weighted mean height (Lorey's height) over sloping terrain in the Qilian mountains region, western China.

Heterogeneity and Controlling Mechanisms of Soil Organic Carbon Stocks Across Erosion Zones in China Under Future Climate Scenarios

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil organic carbon (SOC), as a key indicator of global carbon cycling and climate change response, plays a critical role in regional ecological security and agricultural sustainability. This study employs three machine learning models including the LightGBM, XGBoost, and random forest to simulate the spatial distribution of topsoil SOC stocks

Stand Age, Standard Retention Density and Site Conditions as Drivers of Shoot Biomass Accumulation in Mediterranean Oak Coppices

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Mediterranean oak coppices represent an important fuelwood resource in Central Italy, but management decisions are often constrained by limited quantitative evidence on the relative importance of stand development, standard retention, site conditions, and climate in driving shoot biomass accumulation.

Comparative Effectiveness of Different Mulch Types and Application Rates for Reducing Runoff and Sediment Yield on Forest Skid Trails

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Rehabilitation of skid trails following timber harvesting is critical for preserving forest soil integrity, particularly within ecologically sensitive ecosystems such as the Hyrcanian forests of northern Iran, a UNESCO World Heritage Site. Although mulching is widely recommended for erosion control, field evidence comparing different locally ...
