The influence of winter temperatures on the annual radial growth of six northern-range-margin tree species. Dendrochronologia 22: 7-29. Notes: Most of this collection of QURU raw ring widths was made by N. Pederson mid to upper elevations on a south-facing slope on Prospect Mountain in Lake George, NY. These data were collected for a dendroecological study of southern temperate trees growing at or near a northern range margin. While the oldest trees in the stand were targeted, the goal of field sampling was to collect a range of existing tree ages within the stand. The stand in which they are sampled has little soil depth. However, the forest was dense at the time of sampling and there is much evidence of logging, fire, and (perhaps) grazing at this site. Because of this, detrending of these raw data should be conducted with closed-canopy or forest interior conditions and forest disturbance in mind. The raw data in this collection contains values of -8888 for years where the rings were distorted or otherwise not useful for dendroclimatology. The latest version of ARSTAN reads these as dummy variables and can in-fill these gaps.
