Figure 6. Destabilizing effects of forest recovery rate μ and short-term memory α under governance as a one-time incentive g' for reforestation.

. Time series representing the fraction of forested land (x(t)) under incentive for reforestation. (A) has a forgetting coeffiecient of α = 0.05 and recovery rate μ =  0.1; (B) α = 0.2 and μ =  0.1; (C) α = 0.9 and μ =  0.1; (D) α = 0.05 and μ = 0.5; (E) α = 0.2 and μ = 0.5; (F) α = 0.9 and μ =  0.5 α increases the amplitude of oscillations and μ increases the frequency; increasing values of g decrease stability. Other parameters are b' = 5, c' = 20.
