Table 2 Vegetation characteristics at growing seasonal peak time for clipping treatments where Experiments 2 and 3 were conducted

Treatment	Vegetation cover (%)	Leaf area index	Living biomass (g m⁻²)	Litter (g m⁻²)	Stand dead (g m⁻²)	Average height of vegetation (m)	Number of species
M₂	54 ± 2^a	0.34 ± 0.02^a	66 ± 8^a	48 ± 8^a	25 ± 4^a	0.04 ± 0.01^a	15 ± 1^a
M₁₀	49 ± 2^a	0.38 ± 0.02^a	76 ± 10^a	58 ± 17^a	24 ± 1^a	0.09 ± 0.01^b	14 ± 2^a
M₀	48 ± 5^a	0.48 ± 0.02^b	112 ± 7^b	130 ± 14^b	177 ± 19^b	0.23 ± 0.02^c	12 ± 1^b

M₂, M₁₀, and M₀ showed biomass removal by clipping shoots at heights of 0.02 m, 0.10 m, respectively, once a year in late August since 2003 and no clipping. Values (mean ±1 SE) designated by the same letter (^a, ^b, or ^c) are not significantly different at P = 0.05 among treatments.
