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 CAGL raw ring widths was made by N. Pederson along a small stream valley in rolling terrain of the Lisha Kill preserve near Schenectady, 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 decent soil depth. At the time of sampling, the forest was fairly dense. And, while it is considered to be an old-growth forest, there is evidence of cutting, an old road, and grazing. Many trees are less than 200 years of age or show a large growth release around the beginning of the 19th century. 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.
