Fig. 2.6. Averages and standard deviations of wood and leaf production for mesic hardwood forest ecosystems at various latitudes. Averages are based on 60 studies of wood production and 135 studies of leaf litter production. Individual data values and references are listed in Jordan (1983).

higher nutrient content. In many tropical forests, leaves comprise a relatively high proportion of primary production (Fig. 2.6). In the Luquillo forest of Puerto Rico, Weaver (1995) found that litterfall comprised 90% of the total net primary production. High rates of leaf input to the soil relative to wood input accentuate even further the high decomposer activity and consequent nutrient transformations compared to forests where the proportion of leaves to wood is lower.
