The combination of three strategies of plants:
Productivity Low High Disturbance High Ruderals (R) Low Stress tolerators (S) Competitors (C) Competitors (C)
Plants have high competition ability when low stress and disturbance are given. The high competition ability is evaluated by fast growth rate and high productivity.
Stress tolerators (S)
Plants adapt to high stress and low disturbance, by slow growth rates, long-lived leaves, and high nutrient retention rate. These are represented by species growing in alpine, arid, or sprpentine habitats.
Ruderals (R)
Species favor disturbance with low stress, and are fast-growing. Plants that have adapted this strategy are often found colonizing recently disturbed land, and are often annuals.
