#Metsätiede2025
Afternoon parallel session of the Forest Mensuration Club
In Finland, forest inventories based on laser scanning and aerial imagery have produced data for strategic, tactical and operational forest planning for over a decade. Weaknesses of inventory methods based on remote sensing are considered to be the underestimation of lower canopy layers and inaccuracy of the interpretation of the size distribution of trees.
However, the layers below the dominant story are important for the timing of operations, selecting the right silvicultural method, assessing carbon balance and for identification of old and natural forests.
The afternoon session of the Forest Mensuration Club will focus on different canopy layers from a forest planning and inventory perspective.
Key questions include but are not limited to:
- What do current sensor technology and higher point density enable in describing different layers or the size distribution of trees?
- What do we know about the effects of different canopy layers of forests on growth and yield models?
- What effects do forest layers and continuous cover management have on forest planning methods?
