Secondary succession
An example of Secondary Succession by stages:
1. A stable state in deciduous forests 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 public area 7. Fast growing evergreen trees and bamboo 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. |
climax community
Savanna is a grassland with scattered individual trees. Found covering: Central South America, central and South Africa, and parts of Australia. Soil is generally porous with a thin humus layer. 3 distinct seasons: cool and dry; hot and dry, and warm and wet in that order. Frequent fires inhibit invasion of trees. Large herbivores (giraffes, zebras) are commonly most active.
