Error Analysis on the Five Stand Biomass Growth Estimation Methods for a Sub-Alpine Natural Pine Forest in Yunnan, Southwestern China
above-ground biomass biomass growth error analysis Pinus densata forests
2023/11/22
Forest biomass measurement or estimation is critical for forest monitoring at the stand scale, but errors among different estimations in stand investigation are unclear. Thus, the Pinus densata natura...
Assessing Vegetation Composition and the Indicator Species Around Water Source Areas in a Pine Forest Plantation: A Case Study from Watujali and Silengkong Catchments, Kebumen, Indonesia
indicator species water source catchment
2024/2/29
This research aimed to assess vegetation composition and the indicator species around water source areas of pine forest plantation. Data were collected through interview and vegetation survey. Vegetat...
ASTER AND WORLDVIEW-2 SATELLITE DATA COMPARISON FOR IDENTIFICATION OF GROUNDWATER SALINIZATION EFFECTS ON THE CLASSE PINE FOREST VEGETATION (RAVENNA, ITALY)
Aster WorldView – 2, NDVI
2015/5/6
The availability of a large number of data acquired by satellite sensors with different spatial and spectral resolutions has always required an evaluation of their synergistic use. The integration o...
Changes in Austrian pine forest floor properties in relation with altitude in mountainous areas
altitude Pinus nigra forest floor decomposition organic matter humus
2015/3/12
Altitudinal studies has become of interest to ecologists concentrated on functional alterations aiming to clarify the effects of limiting factors. Nutrient element release from forest floor (FF) decom...
Spatial variability of water repellency in pine forest soil
spatial variability water repellency WDPT test infiltration sorptivity
2015/2/3
The variability of water repellency of pine-forest arenic regosols and its influence on infiltration processes were measured in southwest Slovakia. The water drop penetration time (WDPT) tests of soil...
Altitudinal gradients of natural abundance of stable isotopes of nitrogen and carbon in the needles and soil of a pine forest in Nepal
pine forest Nepal stable isotopes
2015/1/29
This paper deals with natural abundance of 15N and 13C in the soil and needles of the pine forest (Pinus roxburghii, Sargent) along an altitudinal gradient. The study area lies in the elevation range ...
Carbonyl sulfide exchange in a temperate loblolly pine forest grown under ambient and elevated CO2
Carbonyl sulfide loblolly pine forest CO2
2010/2/1
Vegetation, soil and ecosystem level carbonyl sulfide (COS) exchange was observed at Duke Forest, a temperate loblolly pine forest, grown under ambient (Ring 1, R1) and elevated (Ring 2, R2) CO2. Duri...
Needle age-related and seasonal photosynthetic capacity variation is negligible for modelling yearly gas exchange of a sparse temperate Scots pine forest
Needle age-related and seasonal photosynthetic capacity variation a sparse temperate Scots pine forest
2010/1/21
In this study, we quantified the predictive accuracy loss involved with omitting photosynthetic capacity variation for a Scots pine (Pinus sylvestris L.) stand in Flanders, Belgium. Over the course of...
Autumn temperature and carbon balance of a boreal Scots pine forest in Southern Finland
Autumn temperature carbon balance a boreal Scots pine forest Southern Finland
2010/1/21
We analyzed the dynamics of carbon balance components: gross primary production (GPP) and total ecosystem respiration (TER), of a boreal Scots pine forest in Southern Finland. The main focus is on inv...

intrazonal forest on dolomite consequences of forest fire soil damage and degradation
2009/11/26
We studied soil conditions and floristic comsposition in the forest of beech and Hairy Alpenrose (Rhododendro hirsuti-Fagetum) and in the south-Alpine Austrian black pine forest (Fraxino orni-Pinetum ...
Estimation of Canopy Reservoir Capacity and Oxygen-18 Fractionation in Throughfall in a Pine Forest
Canopy Reservoir Capacity Oxygen-18 Fractionation Pine Forest
