This is great! I’m a Professional Timber Cruiser born & raised here in Oregon I was trained by an old friend and I took classes in Forestry under John Bell & Kim Illes at OSU (Oregon State University) therers a great Forestry program here every year on Plot Sampling-Inventory Forestry-3P technique. I use Angle Count Sampling and the 3P technique which is fairly new to me, its very interesting and I hope to learn more. Thanks for Sharing! Especially from Gotttingon, Germany! One of my favorite Teachers went to school in Gottingen, Germany, Dr. Bill Richards one of the oldest Psychedelic Researchers alive.

Great information

This is a really helpful video. As someone new to forestry (within the UK) I've noticed that the forest you film in are much clearer from a ground vegetation perspective. This must make it much easier to take measurements.

We selected very simple forest structures for these videos, which are not necessarily representative for all forests in Germany. You are right that working in close to nature forest structures might complicate the measurements. Inventories are often done in leaf off condition outside the vegetation period in broadleaf forests.

The App I used to measure tree height was developed by Dr. Jürgen Nagel, you find it here: play.google.com/store/apps/details?id=ftools.baumhoehenmesser
