The Deep Impact of IAS on Biodiversity

Invasive species are a major threat to biodiversity as they have a profound impact on economies and ecologies.  They have transformed various habitats all around the world. Invasive species change the structure of ecology, displace native species, and alter food webs. The most damaging invasive species in the Caribbean are black rats, feral cats, pigs, and goats.

The United Nations Programme (UNEP) has estimated that invasive species represent a major factor in the potential extinction of 15% of threatened plant species and 30% of threatened bird species. Invasive species are the biggest threat to biodiversity.

Many Caribbean islands have started programs and campaigns aimed towards preventing and removing invasive species. These methods along with drafting legislature will ensure that a proper system is in place for the prevention of future invasive species.
