Data for: Tree defenses, host choice, and reproductive success of a native bark beetle under novel outbreak conditions, 2011-2013 & 2022-2023, Beltrami Island State Forest, MN

Abstract

This dataset was initially collected as an observational study of tree-bark beetle dynamics during an outbreak of eastern larch beetle in eastern larch forests in Beltrami Island State Forest, Minnesota. Field data was collected from 2011-2013 and includes tree level measurements of size, microsite stand density, and phloem characteristics, as well as tree level measurements of beetle attack density and reproductive success. During the initial field season tree cores were collected to determine tree age. These cores were subsequently scanned in 2022-2023 with high resolution photography to measure core level traits regarding ring width and resin duct density. These data were used to understand the relationship between tree defensive capacity and beetle reproductive success.
