Stem radius change from Picea mariana and Larix laricina at the Old Black Spruce site, Boreal Research Ecosystem and Monitoring Sites (BERMS)

This dataset holds stem radius data collected at the Boreal Ecosystem Research and Monitoring Sites (BERMS). Stem radius change was monitored at the Old Black Spruce site (OBS) (53. 98 ºN, 105.12 °W) from the two dominant tree species, black spruce (Picea mariana) and eastern larch (Larix laricina). The stem radius change was measured with the use of circumference band dendrometers, type DC2 and DC3 from Ecomatik (Ecomatik, Germany), and recorded every 30 min using a HOBO UX120-006M data logger. An array composed of four or less dendrometers were affixed to individual trees of the same species and connect to the same data logger. There was a total of eight arrays at OBS, four monitoring 13 P. mariana trees, and four monitoring 13 L. laricina trees. There are periods where data from less dendrometers are available due to logger failure and/or wild animals interfering on measurements. No gap filling technique was used when gaps were present. This dataset includes data that have been processed for analysis. More details on the measurements and data processing can be found in the README file.
