Accuracy of Vegetation Height and Terrain Elevation Derived from Terrestrial Ecosystem Carbon Inventory Satellite in Forested Areas

Applied Sciences
Forest ecosystems serve as pivotal components of the global carbon cycle, with canopy height representing a critical biophysical parameter for quantifying ecosystem functionality, thereby holding substantial implications for forest resource management ...

Effect of age class on the survivorship and spatial movement patterns of headstarted Texas horned lizards soft‐released into an urban population

The Journal of Wildlife Management, EarlyView.
When compared to resident lizards of the corresponding age class, juvenile headstarted Texas horned lizards soft‐released into an urban population exhibited more favorable responses to short‐term translocation objectives (i.e., daily movement rates, home range sizes, and survival rates) than did conspecifics headstarted to the adult age class ...

Wall‐to‐wall Amazon forest height mapping with Planet NICFI, Aerial LiDAR, and a U‐Net regression model

Remote Sensing in Ecology and Conservation
Tree canopy height is a key indicator of forest biomass, productivity and structure, yet measuring it accurately at regional or larger scales, whether from the ground or remotely, remains challenging.

Modelling forest canopy height by integrating airborne LiDAR samples with satellite Radar and multispectral imagery

International Journal of Applied Earth Observation and Geoinformation, 2018
Spatially-explicit information on forest structure is paramount to estimating aboveground carbon stocks for designing sustainable forest management strategies and mitigating greenhouse gas emissions from deforestation and forest degradation.

Habitat characteristics along spring migration routes of elk, mule deer, and pronghorn in the southern San Juan Mountains

The Journal of Wildlife Management, EarlyView.
We evaluated habitat characteristics of spring migration routes and stopover sites for adult female elk (Cervus canadensis), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana) in the San Juan Mountains (2021–2022) and found species‐specific differences in vegetation structure, terrain, and proximity to land cover types relative to ...

Uncertainties in Forest Canopy Height Estimation From Polarimetric Interferometric SAR Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018
The random volume over ground (RVoG) model has been widely applied to estimate forest tree height from polarimetric synthetic aperture radar (SAR) interferometry (PolInSAR) data for the past two decades. Successful application of the RVoG model requires certain assumptions to be valid for the imaged forest and the acquisition scenarios in order to ...

Northern bobwhites select for native grasses on working grazing land

The Journal of Wildlife Management, EarlyView.
Northern bobwhites in eastern Kentucky selected for native warm‐season grasses at multiple spatial scales in an environment dominated by exotic cool‐season grass cattle forage. Our study suggests that incorporating native warm‐season grass cattle forages into existing operations across the southeastern United States may be a viable working‐lands ...

Comparison of forest canopy height profiles in a mountainous region of Taiwan derived from airborne lidar and unmanned aerial vehicle imagery

GIScience & Remote Sensing, 2019
Tree height is essential for assessing carbon budgets and biodiversity. One of the most commonly used assessment methods is a field survey. However, this approach is extremely challenging for obtaining highly accurate estimates in forests with tall and ...

The use of sun elevation angle for stereogrammetric boreal forest height in open canopies

Remote Sensing of Environment, 2017
Stereogrammetry applied to globally available high resolution spaceborne imagery (HRSI; < 5 m spatial resolution) yields fine-scaled digital surface models (DSMs) of elevation. These DSMs may represent elevations that range from the ground to the vegetation canopy surface, are produced from stereoscopic image pairs (stereopairs) that have a variety of ...

Carbon‐Fixing Bacterial Network Complexity Mediates Soil Multifunctionality in a Panax notoginseng‐Pinus armandii Agroforestry System

Land Degradation &Development, EarlyView.
ABSTRACT Autotrophic carbon‐fixing bacteria (CFB) are central contributors to soil carbon sequestration and biogeochemical carbon cycling in agroforestry ecosystems and can act as reliable biological indicators for evaluating agroforestry ecosystem sustainability.
