Fig. 2: Absolute values of net change of runoff coefficient (│ΔR/P│) influenced by forest coverage and age before treatment events.
From: Natural forest growth and human induced ecosystem disturbance influence water yield in forests

a│ΔR/P│ with forest coverage in DECREASE treatment; b│ΔR/P│ with forest coverage in INCREASE treatment; c│ΔR/P│ with forest age in DECREASE treatment; d│ΔR/P│ with forest age in INCREASE treatment. Shaded area represents 95% confidence interval. DECREASE: felling and thinning treatments directly reduce tree numbers; INCREASE: afforestation and reforestation treatments that favors increasing the number of trees.
