Working in Lore Lindu National Park as a PhD Student – Experiences and Impressions
Doing forest research is so much more than publishing the plain figures and tables that you later find in scientific articles. Whenever we look on a graph or table in such a publication, we should never forget that someone went out deep into the forest to take the measurements and collect the data that we are analyzing and looking at. Many of us had such life-changing experiences as researchers and may still remember field work experiences (damn, why didn't anyone make a video…). After all the fund raising, project planning, preparation, effort and hardship and sweat you suddenly find yourself standing in a beautiful tropical forest and you know it was worth it. Our current PhD student Mary Mulligan is one of those adventurers who has set off and exposed herself to a foreign culture and the endeavors of forest inventory fieldwork in challenging conditions in the beautiful Lore Lindu landscape. Together with a very professional field team and with the support of the Lore Lindu National Park and our partners at the IPB in Bogor and the University of Tadulako in Palu, she has now completed almost a year of forest inventory fieldwork and can look back on unforgettable impressions.

Deriving tree density from angle count sample
Переглядів 986Рік тому
With angle count plots (Bitterlich plots) we get an immediate estimate of the stand basal area (m²/ha) by just counting the IN trees and multiplying with the counting factor used. The inclusion probabilities with this design are proportional to the basal area of the individual trees, what makes the design very efficient for basal area estimation. However, if we like to derive an estimate of tre...
Testing a self-3D printed Dendrometer for stand basal area estimation
Переглядів 893Рік тому
For the establishment of Bitterlich plots we need an angle gauge. A simple alternative to the Mirror Relascope is a Dendrometer or any other simple gauge that defines the fixed opening angles for different basal area factors. Here I test a self 3D printed Dendrometer. Works fine! At the end it is mainly about the border trees that need to be checked, for the many other trees that are clearly IN...

UAV applications in forest monitoring
Переглядів 2,5 тис.Рік тому
Unmanned aerial vehicles (UAVs), sometimes called drones, become more and more relevant for forest monitoring. Together with fast developments of photogrammetry software and the increasing availability of specific sensors, UAVs become a flexible alternative for airborne remote sensing on smaller areas. Together with my colleagues Dr. Hans Fuchs, Dr. Nils Nölke and Nils Griese, we give an overvi...
Forest dieback, bark beetle and fire risk: forest change in the Harz mountains
Переглядів 21 тис.Рік тому
Die Fichtenbestände im Mittelgebirge #Harz sind stark gefährdet durch den #Klimawandel. Wer heute im Harz wandert, sieht nicht nur Mischwald, sondern flächendeckend auch karge Landschaften mit toten oder abgeholzten Fichten. Doch wie kam es zu den Monokulturen? Kann man einen #Wald bauen, der den Klimaveränderungen standhält? Und was hat es mit dem Borkenkäfer auf sich? Der Harz ist das höchste...
