Table 1

Humid tropical forest cover estimates for the years 1990 and 1997 and mean annual change estimates during the 1990–1997 period. All figures are × 106 ha. Sample figures were extrapolated linearly to the dates 1 June 1990 and 1 June 1997. Average observation dates were February 1991 and May 1997 for Latin America, February 1989 and March 1996 for Africa, and May 1990 and June 1997 for Southeast Asia. Estimated ranges are at the 95% confidence level.
