Seeing the forest and the trees: Harnessing signals from dendrometers and tree rings in flux science
Tree cores and automated dendrometers provide powerful insights into multiple facets of tree function. When these measurements are collected at flux tower sites, we have the opportunity to advance our understanding of the relationship between tree and ecosystem function with sub-daily to annual resolution. Harnessing the information from flux towers, automated dendrometers, and tree rings has revealed decoupling and lags between ecosystem uptake of carbon dioxide and tree growth, differential drought and heat legacy effects on ecosystem-scale fluxes and growth, and large differences in water-use efficiency from tree to ecosystem scales. This workshop aims to bring together scientists from the flux tower, tree-ring, and dendrometer communities to develop the next generation of research priorities at the intersection of tree growth and ecosystem fluxes. The workshop will consist of plenary talks, plenary and breakout group discussions, hands-on exercises with data collected at flux tower sites, and a virtual poster session.
The goals of the workshop are:
- Develop a shared perspective on leveraging information from individual tree measurements and ecosystem scale fluxes through community forums: How can these co-located measurements advance our understanding of tree to ecosystem function?
- Knowledge-exchange contributing to a dataset of tree water stress and growth measurements collected at flux tower sites
- Increase coordination between flux tower and tree growth data networks
- Creating a sampling toolbox for future campaigns at flux tower sites
