Forest degradation monitoring system Cycle I (1991-1995) : 3,300 sample plots (SPs) by grid 8km x 8km in the forested area. Cycle I (1991-1995) : 3,300 sample plots (SPs) by grid 8km x 8km in the forested area. Cycle II (1996-2000) : 3,600 SPs by grid 5.6 km x 5.6 km. Cycle II (1996-2000) : 3,600 SPs by grid 5.6 km x 5.6 km. Cycle III (2001-2005) : 4.200 SPs Cycle III (2001-2005) : 4.200 SPs Cycle IV (2006-2010): 2100 SPs by grid 8km x 8km Cycle IV (2006-2010): 2100 SPs by grid 8km x 8km
