Predicting crown radius in eastern white pine (Pinus strobus L.) stands in New Hampshire

Academic Article


  • Abstract Using data from 449 trees on 69 growth-and-yield plots located in southern and central New Hampshire, we developed models of crown radius for stand-grown eastern white pine (Pinus strobus L.) in New Hampshire. In addition to dbh, we tested single-tree measurements sometimes collected in forest inventories (such as live crown length and live crown ratio [LCR]), as well as simple variables to compensate for stand density and competitive position of the tree. A model using dbh, stand basal area (BA), and LCR provided the best predictions, but a model using dbh, stand BA, and the ratio of dbh to stand quadratic mean diameter proved nearly as accurate. We compare these equations to previously published equations for white pine.
