The blog from the State Climate Office of North Carolina posted a new story today about some summer research done on the relationship between total net primary productivity (TNPP) of pines and drought indices.  The research explored statistical correlations between various drought indices like the Palmer Drought Severity Index and the Standardized Precipitation Index and the productivity of pines using data from PINEMAP scientists.  PINEMAP is a USDA-funded research project focusing on pine forestry in the Southeast.  Only weak correlations between drought indices and TNPP were found, but it was not clear if this was due to the coarse nature of the data or just lack of sufficient data n from climate divisions.  To read the blog posting,  click here.  To learn more about PINEMAP, go to
