2. The stable community should be mature, stable, self -sustaining etc.
3. The vegetation will be tolerant of environmental conditions.
4. It must contains variety of species, complex food chains etc.
5. It should contain the greater biodiversity for the stability.
6. This is said to be balanced community and contains equilibrium state between the gross primary production and total respiration etc.
7. It persists as long as the climatic and physiographic condition remains unchanged and we can say it is unreplaceable.
