Deriving tree density from angle count sample
zhlédnutí 622Před 8 měsíci
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
zhlédnutí 579Před 8 měsíci
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
zhlédnutí 1,7KPřed 9 měsíci
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...

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...

    Ich bin gerade eine Woche durch den Harz gewandert. Die Problematik mit den abgestorbenen Fichtenwäldern war mir natürlich bekannt. Vom subjektiven Empfinden hatte ich es mir vorher schlimmer vorgestellt als es am Ende war. Erstaunlich ist wie schnell die Natur sich wieder regeneriert. Auch gibt es noch Bereiche (z. B. Bodetal), die kaum geschädigt sind. Ich kann auf jeden Fall eine Harzwanderung nach wie vor empfehlen.

      I'm used to using a caliper for measuring tree diameter, so I was surprised when I saw most people in videos using measuring sticks or tapes for circumference.

    I liked your phd thesis work in Indonesia. Tropical forests are unique and diverse in nature. We can observe variation in species composition in different plots. May I know which quadrate method did you used for the inventory of the species composition, and what was its size?

    • @dimanamary
      @dimanamary Před měsícem

      Hi! Thanks for the nice questions ☺️ we used 40m x 60m plots, divided into 10m x 10m quadrants. Over the entire plot, we measured diameters and tree heights for all stems >10cm. Then, within each quadrant, we measured stems down to 2cm in a 5m x 5m subplot. Hope that answers your questions 🤠
