Productivity and nutrient analysis of Plains populations of Pinus rigida from southern New Jersey
Buchholz K and Good RE. 1980. Productivity and nutrient analysis of Plains populations of Pinus rigida from southern New Jersey. Bulletin of the Ecological Society of America. 61(2; Program Issue):93
Three areas of dwarf pitch pine (Pinus rigida) known as the Plains from the New Jersey Pine Barrens were sampled for density and productivity. Tissues of pitch pine from the Plains and the normal Barrens trees (and soils from the sites) were analyzed for elemental content of Ca, Cu, Fe, K, Na, N, Mg, P, and Zn. Density is locally highly variable and negatively correlated with stand age. The East Plains has the greatest mean stand stem density (29,400/ha), the lowest mean age (7.7 yr), lowest mean standing biomass (6973 kg/ha), and the lowest mean net annual productivity (1507 kg/ha/yr) of the three Plains areas. Differences in these parameters are attributed to differences in fire frequency. Plains P. rigida have a greater proportion of their biomass distributed in reproductive structures, current needles, and current twigs than Barrens pitch pine.
