1
what is succession?
Change in ecological community/ecosystem over time
2
Climax community?
Final stage where diverse forest is formed(species composition remains relatively unchanged)
3
Primary succession?
1)Starts with pioneer species colonising bare rock/sand
2)Their decomposition results in formation of thin layer of soil(humus).
3)Environment becomes suitable for new species(for at this stage small plants) and they outcompete previous species
4)Repeat 2-3 until it reaches climax community in which all these changes result in increase biodiversity

4
Secondary succession?
When succession is disrupted(natural disasters,humans) and the succession restarts but at higher stage as soil is already created
5
Conservation of habitats?
To conserve a variety of unique habitats, succession is frequently managed:
By maintaining earlier stages and preventing climax community, a larger variety of habitats are conserved and donc greater range of species can exist
Eg: Coppiced trees
