Forests constitute important ecosystems in the global carbon cycle. However, how trees and environmental conditions interact to determine the amount of organic carbon stored in forest soils is a hotly debated subject. In particular, how tree species infl

Forest structure modeling with combined airborne hyperspectral and LiDAR data The interest in the joint use of remote sensing data from multiple sensors has been remarkably increased for environmental applications. This is because a ... FB Koch - 《Remote Sensing of Environment》 被引量: 102发表:...
The importance of tree seedlings in determining future stand composition and structure is well documented in forestry literature. When planned or unanticipated overstory removal events occur, subsequent regeneration success is often linked to the number of seedlings and their height distribution. Yet, in...
The quality of tree attribute data derived from contemporary mobile systems remains unclear. This study evaluated the performance of mobile systems in various forest stand conditions, focusing on three critical factors, i.e., the 3D forest structure, the accuracy of the attribute estimates, including...

The analysis of the data was implemented in two parts: with quantitative modelling using survey and register data and with qualitative content analysis of the responses to open-ended questions of the survey. The different analyses and data used for them are presented in Fig. 1. Datasets and ...
Theory and evidence indicate that trees and other vegetation influence the atmospheric water-cycle in various ways. These influences are more important, more complex, and more poorly characterised than is widely realised. While there is little doubt that
Open access to global forest data, especially ground-measured (in situ) records, is critical for saving the world’s forest systems. Integrated approaches to achieve sustainable data openness will involve legal assurances, shared ethics, innovative fundi
