The Effect of Spatial Scale on the Prediction of Tropical Forest Attributes from Image Texture

Table 1

Mean values for the community structure attributes sampled within plots of different sizes; coefficients of variation are shown in parenthesis.

Forest attribute	Plot size (m^2)
	64	256	1024
H	6.39 (0.19)	6.06 (0.15)	6.01 (0.13)
HSD	2.12 (0.52)	2.18 (0.45)	2.30 (0.39)
D	1689.97 (0.40)	1733.53 (0.31)	1715.67 (0.23)
BA	30.92 (0.60)	31.10 (0.36)	30.92 (0.24)
AGB	114.37 (0.68)	106.82 (0.40)	106.49 (0.26)

H = mean height (m); HSD = standard deviation of height (m); D = density (ind./ha); AGB = aboveground biomass (Mg/ha); and BA = basal area (m²/ha).
