The influence of winter temperatures on the annual radial growth of six northern-range-margin tree species. Dendrochronologia 22: 7-29. Notes: This collection of QURU raw ring widths was made by N. Pederson on rolling terrain within the Montgomery Place Historic site near Barrytown, 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 good soil depth. At the time of sampling, the forest was fairly dense. And, while there are old trees in this collection and maps show intact forest at the time of purchase in the early 19th cenrtury, there is evidence of past logging. Because of this and despite it’s relatively low tolerance of shade, 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.
