Timber Income Liquidity Zones for an Even-Aged Stand

Income from the forest is irregular because most private nonindustrial forests are not managed to provide an even flow of income.  In even-aged forest stands, there are 4 revenue zones, outlined in the chart below.

Zone I II III IV
Age (years) 0-15 16-25 26-35 36-40
Approximate Value
($ per acre) 		0-1000 500-1500 1500-3000 3000-4000

Keep in mind that these values are approximate and are highly dependent on the species, region, site, and the site preparation and intermediate cultural treatments used.
