Large-area forest productivity estimation using bitemporal data from airborne laser scanning and digital aerial photogrammetry
Lennart Noordermeer defended his PhD-thesis, “Large-area forest productivity estimation using bitemporal data from airborne laser scanning and digital aerial photogrammetry”, on May 27, 2020.
Project meeting
On March 10, 2020, the national partners of ForestPotential were gathered for a project meeting.
Skogplanseminar 2020
Completed data collection in 2018
In the period between July and September, a substantial field effort was carried out in the 1,500 km transect from south to north in Norway. Each of the 36 field sites was visited.

The ForestPotential project was kicked off at the RunWay confernce hotel at Gardermoen on the 22nd and 23rd of March 2018. Most of the partners were present or participating online.
In the meeting, each of the partners introduced their field of expertise and recent research activities relevant to the project. Then each work package was presented and discussed in detail. The discussions were very useful and the outlook for a fruitful cooperation to reach the project goals is promising.

Master thesis: Regional differences in recruitment, mortality and growth of pioneer trees in the treeline ecotone
Several factors are affecting the dynamics in the treeline ecotone. Both climate, herbivory and changed landuse affect recruitment, mortality and growth in this trasition zone between forest and alpine areas. In addition to that it can be challenging to quantify the effect of each factor, several local factors are in play, such as ground vegetation, micro topography, aspect etc. This master thesis uses multi-temporal observations of trees in the treeline ecotone of 35 sites distributed along a more than 1000 km latitude gradient, to analyze regional differences in recruitment, mortallity and growth. The thesis includes analyses of the effets of climate and herbivory on the changes in the treeline ecotone. The thesis is a part of the project ForestPotential.
