When an invasive species is successful in its new environment, the native species in the area can experience a variety of outcomes. Some native species may see their populations increase as they adapt to the changes brought on by the invasive species. Others may experience a steady population, neither increasing nor declining. Unfortunately, many native species do experience a decline in population as they struggle to compete with the invasive species for resources such as food and habitat. It is important to monitor the impact of invasive species on native species and take action to prevent further harm.
