Diurnal and Seasonal Variations of Particulate Matter Concentrations in the Urban Forests of Saetgang Ecological Park in Seoul, Korea

Land, 2021
Urban forests provide various ecosystem services. Although the function of reducing particulate matter (PM) in the city is known, research into the reduction of PM according to the type and structure of various forests is still needed. It is essential to

Comparison of LiDAR and Digital Aerial Photogrammetry for Characterizing Canopy Openings in the Boreal Forest of Northern Alberta

Remote Sensing, 2019
Forest canopy openings are a key element of forest structure, influencing a host of ecological dynamics. Light detection and ranging (LiDAR) is the de-facto standard for measuring three-dimensional forest structure, but digital aerial photogrammetry (DAP)

Simulation of Ku-Band Profile Radar Waveform by Extending Radiosity Applicable to Porous Individual Objects (RAPID2) Model

Remote Sensing, 2020
Similar to light detection and ranging (lidar), profile radar can detect forest vertical structure directly. Recently, the first Ku-band profile radar system designed for forest applications, called Tomoradar, has been developed and evaluated in boreal ...

Evaluating Data Inter-Operability of Multiple UAV–LiDAR Systems for Measuring the 3D Structure of Savanna Woodland

Remote Sensing, 2022
For vegetation monitoring, it is crucial to understand which changes are caused by the measurement setup and which changes are true representations of vegetation dynamics.

Evaluating the Use of Lidar to Discern Snag Characteristics Important for Wildlife

Remote Sensing, 2022
Standing dead trees (known as snags) are historically difficult to map and model using airborne laser scanning (ALS), or lidar. Specific snag characteristics are important for wildlife; for instance, a larger snag with a broken top can serve as a nesting

Forest Structure Assessment of a Rehabilitated Forest [PDF]

American Journal of Agricultural and Biological Sciences, 2011
Planteamiento del problema: La evaluación de la estructura forestal proporciona información sobre la sucesión forestal, la dinámica, la biodiversidad y la salud que son importantes, pero solo se dispone de poca información sobre el bosque rehabilitado. El objetivo de este estudio fue evaluar la estructura forestal de los rodales de edad seleccionada en

The influence of the forest management in the Białowieża forest on the species structure of the forest community

Forest Ecology and Management, 2021
Abstract Saving Europe's remaining natural forests is one of the main objectives of the political challenges to stop the ongoing decline of biodiversity. Conservationists and foresters need objective data to assess the success or failure of management actions to conserve biodiversity.

Habitat Specificity Modulates the Response of Small Mammals to Habitat Fragmentation, Loss, and Quality in a Neotropical Savanna

Frontiers in Ecology and Evolution, 2021
Landscape conversion of natural environments into agriculture and pasture are driving a marked biodiversity decline in the tropics. Consequences of fragmentation might depend upon habitat amount in the landscape, while the quality of remnants can also ...

Height-diameter allometry of tropical forest trees [PDF]

, 2010
Tropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry.
