Fig. 2. The regrowth dynamics of temperate, grass-based pastures. Unique regrowth curves (only two shown here, Curve 1 from a low residual state and Curve 2 from a greater residual state) depend on the initial state of each patch, Wi, and there is an optimal time of harvest for that patch (denoted t*def) where a straight line drawn from the intercept with the x axis first touches the curve (Parsons and Chapman, 2000). At even greater residual patch states, regrowth is monotonic, implying the patch should be regrazed immediately.
