Web Application
The ITOFF web application can be used to visualise interactions between invasive and native species. Networks can be generated for all species in the ITOFF database and can be customised by the user. We recommend that all users read the guidance provided below before using the application. The web application is available at:
Guidance
General
- On opening the web application, the menu button located on the top left corner of the screen can be used to access the species list and a search bar is provided.
- Select a species and then use the ‘degree of separation’ slider to control the complexity of the network. Note that only one species will be visible if there are no known connections.
- You can interact with the network by clicking and dragging species. Arrows show the direction of impact between species. Hovering your mouse over an arrow will show the type of impact (e.g. predation, hybridisation). Clicking on a species will bring up the selected species profile.
Species Categorisation
Categorisation of all species in the web application is based on invasive or native status. Native species are categorised as Endangered (EN), Critically Endangered (CR), or Least Concern (LC) in accordance with the IUCN Red List of Threatened Species. Non-native species are categorised as invasive, established, extirpated, failed, or reported. Species are considered reported if known to have been introduced to a novel ecosystem, but survival beyond introduction is unknown. Reported is the default categorisation for all non-native species. Non-native species that successfully founded self-sustaining populations are considered ‘established’. Non-native species that did not survive to establishment are considered ‘failed’. Established species that were later eradicated by human management are considered ‘extirpated’. Finally, species are categorised as ‘invasive’ if there are known (or there is potential for) negative economic, ecological or social impacts.
Note
Networks are generated on the species-level. Species shown can be filtered by climate region however networks do not necessarily represent sympatric species interactions amongst all species shown.
