The study was conducted at GN
division levels. There are about 13 970 GN divisions and data were collected in
12 267 GN divisions covering 87 percent of the country. Each household in the
GN division was visited during the 1996 assessment. Trees grown in home gardens
were classified in three categories based on their main uses: timber, timber
and food, and food. Species were noted and classified according to two girth
classes (below and above 30 cm girth). Data collected at the GN division level
were compiled subsequently toDS division levels.
