Acadia National Park, in Maine, suffered a large wildfire in 1947 of over 10,000 acres. Being nearly 20% of the parks size, many were concerned that the park would be destroyed forever. Restoration efforts were left to nature however, and many think that the choice to not intervene paid off. While the first years were ugly, and only small plants could colonize the burnt soil, many years has led to a great amount of diversity in the tree species. While the trees before the fire were mostly evergreen trees, deciduous forests now dominate the landscape.

In Glacier Bay in southern Alaska succession has been occurring following the melting of a glacier. The glaciers there have been melting for at least the past few hundred years, and as this melting began to occur, plants moved in. The first were mosses and lichens, flowering plants such as the river-beauty ( Epilobium latifolium ), and the mountain avens ( Dryas octopetala ), noted for their ability to "fix" or transform nitrogen into forms usable by the soil. These were the pioneer species, and over time they were replaced by larger plants, such as a short version of the willow. Later, taller shrubs, such as the alder (also a nitrogen-fixing species), dominated the area for about half a century. In time, Sitka spruce ( Picea sitchensis ), western hemlock ( Tsuga heterophylla ), and mountain hemlock ( T. mertensiana ) each had its turn as dominant plant species. With the last group, Glacier Bay reached climax, meaning that the dominant species are not those most tolerant of stresses associated with competition. The habitat thus has reached maturity, and access to resources is allocated as fully as it can be among the dominant species.

What type of succession is occurring:
The stages are predictable and follow in a consistent pattern- for instance in a forest shrubs always follow grasses but then are replaced by larger trees over time
