Unintended Beneficiaries

Wildlife Corridors aretracts of natural land that connect habitats divided by agricultural or other human activities. These are set up to promote spread of native species. But such corridors can also lead to spread of invasive species. A study in Florida, US, found that polygyne fire ants (a type of slow-moving fire ants) were able to use wildlife corridors to spread and dominate the habitat. The study indicates it is crucial to study traits of likely invasive species before setting up a corridor.
