Predicting the volume and biomass of multi-stem maple trees (Acer monspessulanum Subsp. cinerascens Boiss.) based on standing traits is necessary in forestry. In this research twenty sample trees were selected in four transects randomly in Bagh-Shadi Forest of Yazd province. After measuring the diameter at root collar (DRC), tree height, stems numbers and crown diameter and area all trees were ...
The studies were carried out in 2019–2021 the Department of nursery stock RUE “Institute Fruit Growing”. article reflects results studying biological characteristics growth, development and formation vegetative reproductive structures various types seedlings columnar apple varieties. For first time conditions found Belarus features varieties have been set out.
 An effective method limiting...
A rapid nutritional and health evaluation of a random sample of 163 pregnant women was conducted in low socioeconomic settlements of Karachi, with the objective of determining the morbidity and nutritional status of pregnant women. These data are expected to be used in an ongoing community-based antenatal care programme. Twenty-nine percent of women reported fever, 14 percent diarrhoea and 33 p...
Forest understorey contains remarkable plant diversity, contributing to the heterogeneous environments for other biotic gatherings and soil supplement aggregations. Nonetheless, biomass of vegetation is neglected because lack appropriate allometric equations without which there are uncertainties in estimation. This study was aimed at developing multispecies that will be used estimate abovegroun...
ABSTRACT Background: We analyzed if C. lusitanica can be planted in a shelterwood system with P. taeda as the shelter stratum. The study was conducted 13-yr-old stand under canopy Southern Brazil. Samples of these trees were measured terms diameter at breast height (DBH), total height, individual volume, and crown projection area. species´ growing space efficiency (GSE) also analyzed. A 10-mete...
diameter is such a notable characteristic in forest inventory that it is important to have a suitablemethod of its measurement, especially in coppice trees. this seems more important in zagros foreststhat most of them are covered with coppice trees. so this research was aimed to find an efficientmethod in studying the diameter at root collar (drc) of persian oak coppice trees as the mostimporta...
materials and methods in this descriptive and analytical study, we used a static and direct method. cluster sampling method was used to select the subjects. participants were 1600 randomly-selected iranian male (n = 568) and female (n = 1031) workers of five hospitals in bandar abbas. thirty seven static dimensions were measured in the individuals aged 20 - 60. for anthropometric measurement, t...
This study attempted to measure forest resources at the individual tree level using high-resolution images by combining GPS, RS, and Geographic Information System (GIS) technologies. The images were acquired by the WorldView-2 satellite with a resolution of 0.5 m in the panchromatic band and 2.0 m in the multispectral bands. Field data of 90 plots were used to verify the interpreted accuracy. T...
The influence of elevation on the forest development and also more structural elements is evident. aim this paper to research impact relationship between diameter at breast height (DBH), tree (H), crown length (L) stem volume (V). In area Pelister National Park in North Macedonia, 22 experimental plots (EPs) were established even-age Pinus peuce Gris. stands with an average age 90 years. EPs a ...
Korean pine (Pinus koraiensis Sieb. et Zucc.) is the most important forest vegetation in northeast China. The timber quality of this tree species largely driven by branch growth and distribution within crown. Thus, developing diameter length models, especially those that include competition indices, essential. A total 48 trees were selected to conduct destructive measurements characteristics. T...
