Plants and animals animals repopulate an area, changing the environment move easily between the interior and coast, and find as they replace each other. The series of changing plant favorable conditions in the Skagway area due to our and animal life on a disturbed site is succession. relatively dry climate and frequent environmental Typical plant succession in this region may occur as disturbances. Disturbances are events that change the colonizers such as fireweed and devil's club take structure of a habitat. In southeast Alaska, disturbances advantage of forest openings and exposure to the sun. include insect and disease outbreaks, avalanches, Quick-growing trees and shrubs such as alder, birch, landslides, windstorms, and floods - events which allow pine, and cottonwood soon move in.
