002- Human Impact
Although long-term repercussions are not always obvious, introduced species can suddenly become invasive, unraveling ecosystems that took thousands or millions of years to reach a balance. Introduced species can rob native wildlife of water and nutrients, deny local animals of natural food sources and nesting sites, promote harmful organisms, and increase risks such as wildfires.
Introduced ornamental and agricultural plants are common in urban and agricultural areas. Introduced, fast-growing trees are well established in the Jordan River Valley. Introduced fish threaten most native and endemic fish species in river valleys and in Azraq. Introduced parakeets and crows are well-established in Amman and Aqaba. Travel and trade increase the risk of accidental introduction of small organism such as algae and viruses.
