Sampling needle water potentials in #Norwayspruce at the Hurdal @icos-ri.eu site in #Norway. It's been a warm and dry start to the year so curious to see how the trees are doing 🤔🌲

One of the biggest challenges of working in a mature forest is sampling leaves from the canopy- view taken from 20m up in a #norwayspruce forest 😍 We are sampling for pigments and LeafPsi to document the warm and dry conditions in Norway. Credit to Mathias Amundsen for climbing 💪 and video

🪧Calling all researchers working with #dendrometers. The #NordicDendroNetwork is holding its first meeting 13-15 October in Norway. For more information and registration go to >>> shorturl.at/HqoFY

📢Interested in plant drought resistance and tree mortality?🌳🌿

👥Join us to explore key physiological mechanisms behind these processes!

Hi Bob, it's tricky to manage since both point dendrometers require you to drill into the tree, it's hard to know if this will create artifacts in the growth, hence the offset. Then if we keep them in alignment but increase the spacing, it may well also result in different values! Insights welcome!

This is quite opportunistic so only one species (and also, its Norway so Norway spruce 😅). We should definitely compare results though, I think there are others too that have multiple types on the same tree. Definitely worth some investigation!

That's still super powerful data! I just saw a dataset from those type of dendrometers read every 2 weeks for 10+ years and they beautifully document tree decline before mortality (the work involved though 😱)!

That's the plan!

What others are out there? #dendrometers #howmanyistoomany #PREDICT

Europe's most northern beech forests can be found in South-Western Norway 🇳🇴. We are setting up some new monitoring sites of tree growth and drought stress in these beautiful forests #PREDICT #dendrometers @linenybakken.bsky.social

And yes, rainfall exclusion!

Hi Andrew, unfortunately we are only a small team so there is a limit to what we can measure (collaboration always welcome 😎) but we are at least planning to assess overall tree condition including an assessment of cone production. Do you have any protocols that you could recommend? Cheers!

Spent the week installing #dendrometers and #climate sensors in southern Sweden where we are looking at the impacts of chronic drought on Spruce🌲 health, soil 🦠🍄‍🟫 and bark beetle🪲 attack. #sapflow and water potential tensiometers are coming next week! @Maartje klapwijk

It's beginning to look a lot like field season 🌲 First deployment of near-real time growth monitoring equipment ( #dendrometers ) happening next week. #PREDICT #BOREALNET #Norway

📣How have trees being living and dying in Europe over the last 30 years? If this question sounds interesting to you, we have FUNDED positions to work on this topic for 2-6 weeks in some fantastic places via #CLEANFOREST 💀🌲👶🌲
