Quantifying Understory Complexity in Unmanaged Forests Using TLS and Identifying Some of Its Major Drivers

open access: yesRemote Sensing, 2021
The structural complexity of the understory layer of forests or shrub layer vegetation in open shrublands affects many ecosystem functions and services provided by these ecosystems.

Integrating forest structural diversity measurement into ecological research

open access: yesEcosphere, 2023
The measurement of forest structure has evolved steadily due to advances in technology, methodology, and theory. Such advances have greatly increased our capacity to describe key forest structural elements and resulted in a range of measurement ...

Sentinel-2 time series analysis for monitoring multi-taxon biodiversity in mountain beech forests

open access: yesFrontiers in Forests and Global Change, 2023
Biodiversity monitoring represents a major challenge to supporting proper forest ecosystem management and biodiversity conservation. The latter is indeed shifting in recent years from single-species to multi-taxon approaches.

Global humid tropics forest structural condition and forest structural integrity maps [PDF]

open access: yesScientific Data, 2019
AbstractRemotely sensed maps of global forest extent are widely used for conservation assessment and planning. Yet, there is increasing recognition that these efforts must now include elements of forest quality for biodiversity and ecosystem services. Such data are not yet available globally.

Identification of Significative LiDAR Metrics and Comparison of Machine Learning Approaches for Estimating Stand and Diversity Variables in Heterogeneous Brazilian Atlantic Forest

open access: yesRemote Sensing, 2021
Data collection and estimation of variables that describe the structure of tropical forests, diversity, and richness of tree species are challenging tasks.

Mapping Mangrove Zonation Changes in Senegal with Landsat Imagery Using an OBIA Approach Combined with Linear Spectral Unmixing

open access: yesRemote Sensing, 2021
The mangrove areas in Senegal have fluctuated considerably over the last few decades, and it is therefore important to monitor the evolution of forest cover in order to orient and optimise forestry policies. This study presents a method for mapping plant

Effects of climate and plant functional types on forest above-ground biomass accumulation [PDF]

open access: yes, 2023
BackgroundForest above-ground biomass (AGB) accumulation is widely considered an important tool for mitigating climate change. However, the general pattern of forest AGB accumulation associated with age and climate gradients across various forest ...

Evaluation of Forest Edge Structure and Stability in Peri-Urban Forests [PDF]

open access: yesForests, 2020
In the presented research, we studied the forest edge structure of urban and peri-urban forests on the outskirts of Ljubljana (Slovenia) consisting of a number of patches covering the collective surface of 1884 ha. They differ from each other according to the degree of fragmentation and by the share of the interior forest area.
