Analysis of tree stand horizontal structure using random point field methods [PDF]

open access: yesСибирский лесной журнал, 2015
This paper uses the model approach to analyze the horizontal structure of forest stands. The main types of models of random point fields and statistical procedures that can be used to analyze spatial patterns of trees of uneven and even-aged stands are ...

Legacy of Pre-Disturbance Spatial Pattern Determines Early Structural Diversity following Severe Disturbance in Montane Spruce Forests. [PDF]

open access: yesPLoS ONE, 2015
Severe canopy-removing disturbances are native to many temperate forests and radically alter stand structure, but biotic legacies (surviving elements or patterns) can lend continuity to ecosystem function after such events.

Long-term effects of thinning and mixing on stand spatial structure: a case study of Chinese fir plantations

open access: yes, 2021
: The regular planting and periodic harvesting of a single tree species are features of plantations, which are associated with a reduction of biodiversity. Such plantations are strongly encouraged to be converted into mixed forests.

Spatial Variability of Shortwave Irradiance for Snowmelt in Forests [PDF]

open access: yes, 2008
The spatial variation of melt energy can influence snow cover depletion rates and in turn be influenced by the spatial variability of shortwave irradiance to snow.

Spatial structure : a way to understand the dynamics and to model the growth of mixed stands [PDF]

open access: yes, 2005
The aim of this poster communication presented at the fifth workshop IUFRO 5.01.04 WP is to show how spatial structure analysis can be used to improve our knowledge of heterogeneous forest and to provide some perspectives for their modelling. In order to answer this question, we applied an analysis of spatial structure to a mixed stand of Oak and Scots

A novel model to evaluate spatial structure in thinned conifer-broadleaved mixed natural forests

open access: yesJournal of Forest Research, 2023
In order to ensure the effective analysis and reconstruction of forests, it is key to ensure the quantitative description of their spatial structure.

A New Tree-Level Multi-Objective Forest Harvest Model (MO-PSO): Integrating Neighborhood Indices and PSO Algorithm to Improve the Optimization Effect of Spatial Structure

open access: yesForests, 2023
Accurate, efficient, impersonal harvesting models play a very important role in optimizing stand spatial structural and guiding forest harvest practices. However, existing studies mainly focus on the single-objective optimization and evaluation of forest

Modelling the spatial structure of complex stands by point processes : [Abstract] [PDF]

open access: yes, 2007
There is a growing interest for complex - uneven-aged and /or mixed- stands. The dynamics of these stands are more difficult to understand than those of pure and even-aged stands. Thus, new research questions have arisen in terms of stand description, stand dynamics and modelling.

Spatial Analysis of a mixed Beech, Spruce and Fir stand in the Eastern Alps [PDF]

open access: yes, 2022
In a forest reserve, located in the Eastern Italian Alps, a 4 ha permanent plot has been set up in a beech-spruce-fir multilayered forest, left to natural evolution for more than 30 years, in order to detect stand structure and spatial patterns ...
