The term pioneer species is also used to refer to the first species, usually plants, to return to an area after disturbance as part of the process of secondary succession. Disturbances may include floods, tornadoes, forest fires, deforestation, or clearing by other means. [18] Pioneer species tend to be fast-growing, shade-intolerant, and tend ...
Primary succession is the beginning step of ecological succession where species known as pioneer species colonize an uninhabited site, which usually occurs in an environment devoid of vegetation and other organisms. In contrast, secondary succession occurs on substrates that previously supported vegetation before an ecological disturbance. This ...
To counter this, they use a strategy called "cultivation grazing". This grazing can alter the composition of seagrass communities and favor species. Early and rapidly growing species will succeed over slow-growing species. Oftentimes, these "pioneer" species can be high in nitrogen and low in fibre, making them a preferred diet for the dugongs.
An example of pioneer species, in forests of northeastern North America are Betula papyrifera (White birch) and Prunus serotina (Black cherry), that are particularly well-adapted to exploit large gaps in forest canopies, but are intolerant of shade and are eventually replaced by other shade-tolerant species in the absence of disturbances that ...
It is a pioneer species that quickly colonizes open areas with little competition, such as the sites of forest fires and forest clearings. Plants grow and flower as long as there is open space and plenty of light. Fireweed reaches its average peak colonization after five years and then begins to be replaced as trees and brush grow larger.
Many species have a narrow altitudinal and ecological niche, with certain species specializing in specific habitats, such as seasonally inundated habitats, rocky slopes, swamps, natural or man-made clearings, etc. Species in the genus Cecropia are some of the most abundant pioneer tree species in natural tree-fall gaps inside primary forests ...
It grows well in areas of open woodland such as the Mashonaland plateau in Zimbabwe and northern Kwazulu-Natal region of South Africa, where it assumes a broad crown with heavy branches, and is a pioneer species on woodland and forest margins. The best specimens grow in the seasonal closed woodland of central Mozambique and parts of Malawi ...
Macaranga tanarius is a plant found in South East Asia, Thailand, Papua New Guinea, South China, Taiwan, and eastern Australia.It is commonly seen as a pioneer species in disturbed rainforest areas.
