tropical semideciduous seasonal forest ecological restoration agroforestry ecosystem services Legal Reserve
2024/3/5
Reliable estimates of tree growth and wood yield are fundamental to support the management of restored forests and better reconcile the objectives of recovering biodiversity with the provision of ecos...
ANALYSIS OF THE SIDE-LAP EFFECT ON FULL-WAVEFORM LIDAR DATA ACQUISITION FOR THE ESTIMATION OF FOREST STRUCTURE VARIABLES
LiDAR full-waveform overlap stripe differences density changes forest structure canopy fuel comparison of paired samples
2016/11/30
LiDAR full-waveform provides a better description of the physical and forest vertical structure properties than discrete LiDAR since it registers the full wave that interacts with the canopy. In this ...
In rainforests,battle for sunlight shapes forest structure
rainforests sunlight shapes forest structure
2016/1/17
Despite their diversity, the structure of most tropical rainforests is highly predictable. Scientists have described the various sizes of the trees by a simple mathematical relationship called a power...

2015/8/19
Forest structure is a key element to determine the capacity of mountain forests to protect people and their assets against natural hazards. Airborne laser scanning offers new ways for describing fores...
On the way to continuous cover forest at middle elevations – the question of forest structure and specific site characteristics
Dauerwald stand transformation diversity production waterlogged site
2015/4/24
The transformation process of even-aged forest stands to irregular forest stands on waterlogged sites after 20 years effort was analysed. Data from two 1-ha PRP was analysed with special focus on stru...
