an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.

• Pioneer species

• Ecological succession

• Climax community

• Secondary succession

newly exposed or newly formed rock is colonized by living things for the first time. Certain hardy plants and lichens with few soil requirements, called pioneer species, colonize the area first.

• Climax community

• Primary succession

• Ecological succession

• Secondary succession

usually modify the environment so that it can support the other organisms that form the community.

• Pioneer Species

• Foundation Species

• Invasive Species
