We reached the end of the pole, the sun lit part of the crown is out of reach for our clipper. So we needed to deploy an alternative method to retrieve branches for the @icos-ri.eu nutrient and leaf area/mass analysis. If someone has a drone for branch sampling, we are happy to test it next year.

Interesting results from @holisoils.bsky.social. Thanks for the great presentation in the visual story, worth the read indeed.
