Metrics of Growth Habit Derived from the 3D Tree Point Cloud Used for Species Determination-A New Approach in Botanical Taxonomy Tested on Dragon Tree Group Example
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2020)
Detailed, three-dimensional modeling of trees is a new approach in botanical taxonomy. Representations of individual trees are a prerequisite for accurate assessments of tree growth and morphological metronomy. This study ...
Comparative Time Study of Conventional Cut-To-Length and an Integrated Harvesting Method-A Case Study
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2018)
Logging residues offer a significant contribution to the economical profitability and sustainability of forest-based resources. It is always desirable to optimise the harvesting and extraction method to improve the economy ...
Analysis of serious and fatal occupational accidents associated with tractors in agriculture and forestry in the Czech Republic

Management Intensity and Forest Successional Stages as Significant Determinants of Small Mammal Communities in a Lowland Floodplain Forest
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2020)
The conversion of forests from complex natural ecosystems to simplified commercial woodlands is one of the major causes of biodiversity loss. To maintain biodiversity, we need to understand how current management practices ...
Remote infiltration areas as a main source of ground water for floodplain forest without floods
(Mendelova univerzita v Brně, 2019)
This article brings new information about phenomenon of the growth of floodplain forest without influence of floods over 50 years. Floodplain forest and its hydrogeological regime are under detail research for 10 years and ...

Uganda is richly endowed with flora and fauna. Until the early 2000s, most of the types of vegetation have remained natural/virgin forests and shrubs until recent years, when human activities have damaged them. Understanding ...
Effects of a Trench as a Moisture Harvesting Structure on the Biomass Production and Growth of Trees Planted to Restore Degraded Land, Southern Ethiopia
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2020)
Knowledge about the biomass productivity of trees planted in a rainwater harvesting structure, i.e., a trench (T), relative to a normal pit (P) on degraded land is scarce. The objective of this research paper is to compare ...
