We are exploring tree growth using a number of tools at several scales: from cell addition during the growing season, dendrometer band measurements through the year, and annual surveys of thousands of trees.
Tree growth is fundamental to the carbon cycle, strongly correlates with survival, and reflects evolutionary tradeoffs in allocation strategies. Yet growth, whether bole growth, root growth, or leaf turnover is remarkably difficult to measure.
In 2014 we completed the second census of our ForestGEO plot here at SERC. CTFS-ForestGEO is a network of forest plots across the world. The sites follow the same protocol to create a vast database that offers millions of growth measurements on a five year re-measurement cycle.
