Table 2. Ecological and productive performance of action, habitat and result-oriented scenarios.
| Action oriented | Habitat oriented | Result oriented | |
| Productive performance(LU.days/ha) | 1313(95) | 1321(74) | 1339(58) |
| Ecological performance(Population size) | 4(1) | 29(4) | 31(2) |
Means and standard deviation () are given for three random samples of 10 000 viable state trajectories and viable grazing strategies. Productive performance P(u,T) is the number of livestock unit.days ha−1 (LU.days/ha) characterizing a grazing strategy. The ecological performance N(T) is the bird population size at time horizon (starting with N(t0) = 30).
