Table 6. Results from linear mixed-effects models on rate of forest gain.

Fixed effects: rate of forest gain ∼ time(AIC value  = 1911)
	Value	Std. Error	DF	t-value	p-value
Intercept	1.1289	0.1174	341	9.6162	0.0000
Time	−0.5432	0.0742	341	−7.3208	0.0000

According to AIC values, the random intercept model was the optimal structure of the random component.
