Only one-third of the estimated 4.20 million hectare forest area or 4.8 percent of Pakistan's total geographical area is productive while the remaining two-third is maintained for environmental protection. According to official sources, the forest sector, owing to very small productive forest area in the country, contributed about 0.1 percent to the Gross Domestic Product (GDP) and 0.4 percent to the agricultural sector during the fiscal year 1998-99.
