  • Economic Impact of IAS in the Caribbean: Case Studies

    • Apr 28, 2015

    • CAB International.

    • To date no studies have been undertaken on the costs and benefits of IAS management in the Caribbean. This may partly explain why there has been negligible funding to combat the onslaught of these exotic species in the region. As a result it was decided to provide individuals involved in the UNEP-GEF Project, "Mitigating the Threats of Invasive Alien Species in the Insular Caribbean" with training and an opportunity to undertake Cost-Benefit Analyses (CBAs) on some selected IAS. The CBAs undertaken and reported in this publication clearly demonstrates that the benefits of managing IAS outweigh the costs.

  • Emerald Ash Borer

    • Canadian Food Inspection Agency.

    • The emerald ash borer (EAB) is a highly destructive invasive beetle which attacks and kills all species of ash, but not mountain ash, which in spite of its name, is a completely different species of tree. To help prevent the spread of EAB, the movement of ash logs and firewood out of regulated areas is restricted. Report any detections outside of regulated areas to the Canadian Food Inspection Agency (CFIA).

  • Environmental DNA

    • Invasive Carp Regional Coordinating Committee.

    • Environmental DNA (eDNA) is the genetic material from a plant or animal that is found in the air, water or soil. Fish, such as invasive carp, release DNA into the environment in the form of skin cells, secretions, and feces. This DNA can be collected from water samples in the field and be used to indicate the potential presence of an individual species. eDNA testing is useful as a potential early indicator of invasive carp presence and was developed to improve monitoring of such aquatic invasive species.
