Caribbean Invasive Species Working Group

The Caribbean Invasive Species Working Group is a regional network that coordinates invasive species prevention, management, and research across the Caribbean islands. It brings together conservation practitioners, scientists, and policy actors to address biological invasions affecting biodiversity hotspots, island ecosystems, and cultural landscapes. The group engages with intergovernmental bodies, academic institutions, and local agencies to harmonize responses to invasive vertebrates, invertebrates, and plants.

Overview

The Working Group functions as a focal point for capacity building among practitioners from entities such as United Nations Environment Programme, International Union for Conservation of Nature, BirdLife International, The Nature Conservancy, and regional bodies like Caribbean Community and Organization of Eastern Caribbean States. Members include specialists from universities such as University of the West Indies, Florida International University, and McGill University as well as museums like the Smithsonian Institution and the Natural History Museum, London. The group addresses species of concern including invasive rodents, amphibians, reptiles, crustaceans, and plants implicated in declines of endemics on islands such as Cuba, Jamaica, Haiti, Puerto Rico, and the Bahamas.

History and Formation

The group emerged from technical workshops and meetings held alongside conferences like the Convention on Biological Diversity Conference of the Parties and regional meetings of Caribbean Conservation Association and the Western Hemisphere Migratory Species Initiative. Early convenings involved representatives from United States Fish and Wildlife Service, USDA, and Caribbean ministries linked to efforts following high-profile invasive events on islands such as Dominica and St. Lucia. Formalization in the late 1990s and 2000s drew on precedent from networks like the Global Invasive Species Programme and collaborations with IUCN Species Survival Commission specialist groups.

Organization and Governance

Governance has been characterized by a rotating coordination committee with leads from territories including Trinidad and Tobago, Barbados, Grenada, and Saint Lucia. Advisory members have included representatives from multilateral organizations such as Caribbean Development Bank and donor agencies like United States Agency for International Development and European Commission. Decision-making blends technical steering committees, working parties on taxa, and ad hoc task forces that coordinate with national authorities such as the Jamaica Ministry of Agriculture and the Puerto Rico Department of Natural and Environmental Resources.

Programs and Activities

Core activities include rapid response protocols, eradication campaigns, public outreach, and biosecurity training. Initiatives have targeted invasive mammals on islands following models from eradication efforts on South Georgia and the South Sandwich Islands and lessons drawn from campaigns in New Zealand and Australia. Education and community engagement programs have partnered with entities like Caribbean Youth Environment Network and the World Wildlife Fund to promote invasive species awareness at sites such as Morne Trois Pitons National Park and El Yunque National Forest.

Research and Monitoring

The group supports applied research on pathways, population dynamics, and impact assessment in collaboration with laboratories at Universidad de Puerto Rico, University of the West Indies St. Augustine, and research centres linked to Smithsonian Tropical Research Institute. Monitoring protocols incorporate genetic tools from studies at institutions like Cold Spring Harbor Laboratory and satellite mapping approaches used by National Aeronautics and Space Administration and regional meteorological services. Targeted monitoring has informed response to species including invasive lionfish affecting reefs near The Grenadines and invasive amphibians recorded on Cuba.

Partnerships and Collaborations

Partnerships span international organizations such as Convention on International Trade in Endangered Species of Wild Fauna and Flora, International Plant Protection Convention, and regional organizations like the Caribbean Environmental Health Institute. Collaborative projects have involved conservation NGOs including Island Conservation, Re:wild, and academic consortia formed with University of Florida and Cornell University for capacity building and policy guidance. The group liaises with customs and quarantine services across territories and with donor institutions including Global Environment Facility.

Impact and Conservation Outcomes

Through coordinated eradication, surveillance, and policy advocacy, the Working Group has contributed to measurable outcomes: reduced incidence of invasive rat populations on priority islets, improved biosecurity protocols at ports of entry modeled after best practices from International Civil Aviation Organization, and strengthened legislative frameworks adapted from regional templates used in Barbados and Trinidad and Tobago. Conservation outcomes include stabilization of populations of endemic seabirds on archipelagos and mitigation of coral reef impacts from invasive predators in areas such as Belize Barrier Reef Reserve System. Continued work aims to integrate climate resilience considerations advocated by entities like Intergovernmental Panel on Climate Change and regional disaster risk management agencies.
