Pioneer species
First species to colonize or inhabit damaged ecosystems / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Pioneer species?
Summarize this article for a 10 year old
Pioneer species are resilient species that are the first to colonize barren environments, or to repopulate disrupted biodiverse steady-state ecosystems as part of ecological succession. A number of kinds of events can create good conditions for pioneers, including disruption by natural disasters, such as wildfire, flood, mudslide, lava flow or a climate-related extinction event[1] or by anthropogenic habitat destruction, such as through land clearance for agriculture or construction or industrial damage. Pioneer species play an important role in creating soil in primary succession, and stabilizing soil and nutrients in secondary succession.[2]
For humans pioneer species, because they quickly occupy disrupted spaces, are sometimes treated as weeds or nuisance wildlife, such as the Common Dandelion or stinging nettle.[3][2] Even though human have mixed relationships with the plants, these species tend to help improve the ecosystem because they can break up compacted soils and accumulate nutrients that help with transition back to a more mature ecosystem.[4][5][2] In human managed ecological restoration or agroforestry, trees and herbaceous pioneers can be used to restore soil qualities and provide shelter for slower growing or more demanding plants.[5][6][7] Some systems use introduced species to restore the ecosystem,[2] or for environmental remediation.[8] The durable and characteristics of pioneer species can also make them to become potential invasive species, or interfere with biodiversity by quickly occupying an area.[9] [2][10]
