Monitoring Bark Beetle Forest Damage in Central Europe. A Remote Sensing Approach Validated with Field Data
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2020)
Over the last decades, climate change has triggered an increase in the frequency of sprucebark beetle (Ips typographusL.) in Central Europe. More than 50% of forests in the Czech Republic areseriously threatened by this ...
Comparison of Different Remote Sensing Methods for 3D Modeling of Small Rock Outcrops
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2020)
This paper reviews the use of modern 3D image-based and Light Detection and Ranging (LiDAR) methods of surface reconstruction techniques for high fidelity surveys of small rock outcrops to highlight their potential within ...
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 ...
Analysis of serious and fatal occupational accidents associated with tractors in agriculture and forestry in the Czech Republic
(Mendelova univerzita v Brně, 2020)
Agriculture and forestry have traditionally been one of the most hazardous occupations for workers. In both these sectors the tractor is one of the most used machinery. From a total of 89 detected serious and fatal accidents ...
Provenance affects the growth and mortality of teak (Tectona grandis L.f.) plantations cultivated in central Nicaragua
(Česká akademie zemědělských věd, 2023)
Teak has been planted extensively by smallholders in Central America within reforestation programmes and has become one of the most valuable timbers. The five-year growth and mortality of teak cultivated in a plantation ...
Visual Exposure of Rock Outcrops in the Context of a Forest Disease Outbreak Simulation Based on a Canopy Height Model and Spectral Information Acquired by an Unmanned Aerial Vehicle
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2020)
This research was focused on the study of visual exposure evolution in the locality of the Drátenická skála nature monument (in the Czech Republic) and the surrounding forest complex in terms of history and through modelling ...
Comparison of LiDAR-based Models for True Leaf Area Index and Effective Leaf Area Index Estimation in Young Beech Forests
(Mendelova univerzita v Brně, 2020)
The leaf area index (LAI) is one of the most common leaf area and canopy structure quantifiers. Direct LAI measurement and determination of canopy characteristics in larger areas is unrealistic due to the large number of ...
