PAI may go negative if a tree loses volume due to damage or disease. Periodic annual increment is commonly used instead of current annual increment as a basis for computing growth per cent . Growth per cent indicates the rate of increase with relation to the wood capital required for its production, this is usually based on a single year's growth.
The rate of global tree cover loss has approximately doubled since 2001, to an annual loss approaching an area the size of Italy. [ 3 ] Home to much of the Amazon rainforest , Brazil's tropical primary (old-growth) forest loss greatly exceeds that of other countries.
