Using inventory variables for practical biodiversity assessment in plantation stands

Forest Systems, 2022
Aim of study: Practically and simply assessing biodiversity by using inventory variables in four types of forest plantation stands (mixed and pure) including species such are chestnut, blue gum and maritime pine.

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.

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 ...

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.

Forest structures across Europe

Geoscience Data Journal, 2017
Pan‐European gridded datasets derived from a single methodology to inform researchers, policy makers and conservationists on the state of forest structures would improve our ability to study forests independent of political boundaries and along various gradients.

Forest structure and carbon dynamics in Amazonian tropical rain forests [PDF]

Oecologia, 2004
Living trees constitute one of the major stocks of carbon in tropical forests. A better understanding of variations in the dynamics and structure of tropical forests is necessary for predicting the potential for these ecosystems to lose or store carbon, and for understanding how they recover from disturbance.
