Abstract
The Southwide Pine Seed Source Study (SPSSS) provided a tremendous amount of information from its inception in the early 1950s until its conclusion decades later. The silvicultural value of this genetics study, even given some design weaknesses and other limitations, continues to this day and these data will soon be available through the U.S. Department of Agriculture, Forest Service’s Research Data Archive. However, while preparing these data, we discovered in the original study plan documentation that most of the geographic coordinates provided for the seed sources were erroneously located. While some of these errors were very minor, others had significantly different latitudes and longitudes. Such departure errors probably had little to no impact on the earlier interpretations of seed source performance; however, they may prove problematic if used in modern geographic analyses that require more precise sample locations. We demonstrate a number of these errors through a series of species-based tables and maps and provide improved coordinates for future researchers.
