Summary
| Description |
English: This is an example of Secondary Succession by stages: 1. A stable deciduous forest community 2. A disturbance, such as a wild fire, destroys the forest 3. The fire burns the forest to the ground 4. The fire leaves behind empty, but not destroyed, soil 5. Grasses and other herbaceous plants grow back first 6. Small bushes and trees begin to colonize the area 7. Fast growing evergreen trees develop to their fullest, while shade-tolerant trees develop in the understory 8. The short-lived and shade intolerant evergreen trees die as the larger deciduous trees overtop them. The ecosystem is now back to a similar state to where it began.
Français : Exemple de succession faisant suite à une perturbation (incendie): 1. Stade théorique de la forêt décidue climacique 2. perturbation par le feu. 3. Le feu détruit la forêt jusqu'au niveau du sol 4. Le feu laisse derrière lui un vide, mais il n'a pas détruit le sol et une partie de son stock de graines. Le vent, l'eau ou les animaux apportent des graines. 5. Des graminées et d'autres plantes herbacées repoussent d'abord (pionnières). 6. Des petits buissons et jeunes arbres commencent à recoloniser la zone 7. Croissance rapide de conifères, et croissance lente de feuillus tolérant l'ombre dans les sous-étage. 8 Disparition des espèces éphémères intolérantes à l'ombre au fur et à mesure que les grands arbres à feuilles persistantes ou caduques "densifient" la canopée. L'écosystème est maintenant revenu à un état semblable à celui où il a commencé, jusqu'à la prochaine perturbation |
