What are Alien Invasive Species?
Species that are non-native to an ecosystem, can cause economic or environmental harm. In particular, they impact biodiversity, including the decline or elimination of native species - through competition, predation, or transmission of pathogens - and the disruption of local ecosystems and ecosystem functions.
High Level Goal
Alien invasive species (AIS) are not significantly impacting ecosystem health and services in the North-east Tobago Man and the Biosphere Reserve (NETMABR).
Current Situation
AIS already impact North-east Tobago’s biodiversity, ecosystems, agriculture, fisheries, and other livelihoods, economies, and public health. Currently, AIS databases indicate 14 AIS for the NETMABR; however, they urgently require updating. The tropical kudzu, common bamboo, pitch apple (locally: parrot apple), and lionfish are the primary species of concern. Unfortunately, as of 2023, there are no continuous and systematic programmes to address AIS issues in North-east Tobago.
Priority Needs
-
The legal and regulatory framework for the management of AIS is improved and implemented.
-
Direct and indirect threats of AIS to ecosystem health biodiversity and livelihoods are minimised.
Strategies
-
Adaptation and implementation of the National Invasive Alien Species Strategy;
-
creation and maintenance of an open-access AIS database, linked to the national Biodiversity Information System;
-
development of an AIS watchlist;
-
implementation of species-specific biosecurity and control measures for priority species and habitats;
-
implementation of local, community- and stakeholder-based monitoring programmes; and
-
development and implementation of an AIS engagement and communication plan.
