Although partial cross sections from live trees have been utilized in the development of fire history studies, few efforts have been made to examine the effects of this method on the individual trees that were sampled. We examined 115 red pine (Pinus resinosa Ait.), eastern white pine (Pinus strobus L.), and jack pine (Pinus banksiana Lamb.) trees from which partial cross sections had been removed 2years earlier, and 209 similarly sized neighboring red pine and eastern white pine trees. Two years following the removal of partial cross sections, 22 sampled trees (19%) had died. When compared with neighboring trees, removing…

 Highlights: ► We analyze the mortality of live partial cross-section sampled trees. ► We observed no statistical difference in mortality between sampled and control trees. ► Removing cross sections from corners of trees increases mortality. ► Removing more than 30% of the cross sectional area increases mortality.
