From june to september 1988, 51 different wildfires started in yellowstone park. by the end of the summer, approximately 794,000 acres of the park were affected, which included about 24 percent of the whitebark pine forest population, many lodgepole pine stands, and a variety of other plants and animals. which type of change was seen in the ecosystems that were affected by the 1988 fires in yellowstone park? primary succession secondary succession a climax community species extinction

The type of change that was seen in the ecosystems that were affected by the 1988 fires in Yellowstone Park is SECONDARY SUCCESSION.

Succession is the process by which the ecological structure of a community changes over time. There are two basic types of ecological succession, these are primary and secondary succession. A succession is said to be secondary, if the succession process is started by an occurrence which reduces an already established ecosystem to a smaller population of species.

In the question given above, the type of succession that occurred was secondary succession, this is because the wildfires destroyed some of the animals and plants that are found at Yellowstone Park thus reducing the number of plants and animal species found in that ecosystem.

Secondary succession is the type which is brought about due to an ecologically harmful event that destroys the ecosystem and brings about changes that are harmful to the existing life it contains. Usually, this kills a great majority of the wildlife and reduces it to a fraction of itself, making them adapt to the new surrounding.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
