Other pools such as soil carbon and forest products are assumed not to be influenced by disturbances. Carbon also flows from detritus to soil to simulate the effects of extensive decomposition. Whenever a disturbance occurs time is reset to 0 so that live biomass will decrease to 0 as well. Where m is the mortality rate-constant. Where h is the fraction of live vegetation that is removed by harvest.
Forest products are input from living vegetation periodically by harvest.
The amount of harvest that ends up in forest products after manufacturing is variable, as is the longevity of the products themselves. PK t is the loss from decomposition, incineration, and other mechanisms that release forest products to the atmosphere. Where mf is the manufacturing efficiency expressed as a fraction of the harvest turned into long-term forest products, h is the fraction of live carbon harvested, and L t is the live carbon store the year of the harvest. The average total store and flux are presented on the spreadsheet inside the yellow colored box. These represent the value that would be found at the landscape level for a regulated system, that is one in which the disturbance is repeated at regular intervals.
