As a direct visual evaluation, the spread in scattergrams of assimilation index over tree height was examined, for the various model variants and data sets.
Silvicultural characteristics that play the greatest role on tree stability are crown ratio (CR), crown asymmetry index (CAI), and tree height (H).
The main goal of this study was to examine the influence of topography (slope aspect, percent slope, and slope position as calculated from a landform index (LI)) and plot characteristics (tree height, age, and canopy cover) on the distribution of trees (diameter at breast height, dbh≥10 cm), saplings (dbh<10 cm), and CWD in a mixed-oak forest of unglaciated southern Ohio (USA).
The input variables for SISPINUS were: number of trees per hectare = 1,667; site index = 23 m (dominant tree height) at age 15 years; and rotation age = 18 years for an unthinned hypothetical stand.
This study explores the potential of using Landsat-5 Thematic Mapper (TM) imagery in estimating urban forest structural attributes including stem density, diameter at breast height, tree height, leaf area index, canopy density and basal area.
Thus, relative tree height was a good index of the competitive position for the light environment when the trees of both slope positions were pooled.
In order to answer this question, we compared seawall and natural mangrove stands with respect to their relative species contributions to stand complexity, tree diameter, height, leaf size, root density, diameter and tree height size classes, complexity index, and mean stand diameter.
As literature data indicate that mean evaporation rate is independent of tree height and leaf area index, it can be concluded that canopy interception is mainly governed by rainfall regime rather than forest architecture in the high rainfall intensity areas.
Stemflow hydrochemistry was mainly controlled by meteorology (precipitation magnitude and duration), ecosystem characteristics (topography and plant area index) and species-specific traits (stem diameter and tree height).
Throughfall showed significant relationships with actual BA, surface roughness (as tree height variability) and leaf area index (LAI), all of which varied significantly among treatments (as expected).
