Integrating terrestrial and airborne laser scanning for the assessment of single-tree attributes in Mediterranean forest stands

European Journal of Remote Sensing, 2018
The development of laser scanning technologies has gradually modified methods for forest mensuration and inventory. The main objective of this study is to assess the potential of integrating ALS and TLS data in a complex mixed Mediterranean forest for ...

Associations between canopy openness, butterfly resources, butterfly richness and abundance along forest trails in planted and natural forests

European Journal of Entomology, 2017
Increasing the biodiversity in plantations of trees is an important issue because plantations have replaced many natural and semi-natural ecosystems worldwide.

Maximum likelihood parametric reconstruction of forest vertical structure from inclined laser quadrat sampling. [PDF]

, 2014
Forest vertical structure is critical to ecological function, and provides a crucial link to air- and spaceborne remote sensing (including LiDAR), but is difficult to measure from the ground.

Differences in the structure, species composition and diversity of primary and harvested forests on Changbai Mountain, Northeast China

Journal of Forest Science, 2010
Broadleaved-Korean pine (Pinus koraiensis) mixed forest is a typical vegetation type in the eastern Eurasian continent. We compared the structure, composition and diversity of a primary forest and a logged forest for effective management and regeneration

Forest restoration thinning accelerates development of old‐growth characteristics in the coastal Pacific Northwest, USA

Conservation Science and Practice, 2023
A century of industrial‐scale management has transformed vast swaths of forest land across the Pacific Northwest (PNW), USA, from ancient forests with complex structure and diverse habitats to young forests with simple structure and dominated by few ...

Development of forest structure and leaf area in secondary forests regenerating on abandoned pastures in Central Amazonia [PDF]

, 2005
The area of secondary forest (SF) regenerating from pastures is increasing in the Amazon basin; however, the return of forest and canopy structure following abandonment is not well understood. This study examined the development of leaf area index (LAI),

Using Model Analysis to Unveil Hidden Patterns in Tropical Forest Structures

Frontiers in Ecology and Evolution, 2021
When ordinating plots of tropical rain forests using stand-level structural attributes such as biomass, basal area and the number of trees in different size classes, two patterns often emerge: a gradient from poorly to highly stocked plots and high ...

Deriving Tree Size Distributions of Tropical Forests from Lidar

Remote Sensing, 2021
Remote sensing is an important tool to monitor forests to rapidly detect changes due to global change and other threats. Here, we present a novel methodology to infer the tree size distribution from light detection and ranging (lidar) measurements.

Retention of harvest residues promotes the accumulation of topsoil organic carbon by increasing particulate organic carbon in a Chinese fir plantation

Forest Ecosystems
Background: As commonly used harvest residue management practices in subtropical plantations, stem only harvesting (SOH) and whole tree harvesting (WTH) are expected to affect soil organic carbon (SOC) content.
