The Northern Hardwood Ecosystem at Hubbard Brook in Relation to Other Forested Ecosystems in the Wo small area, 92% of the earth’s plant biomass and 46% of its annual net primary production come from forests (Table 21). The 79.9 billion metric tons of dry plant matter produced (net) each year by forests exceeds the total net primary production of the oceans, even though the oceans are more than s
