The Global Invasive Species Programme (GISP) was extremely active until 2010, when it was forced to cease operations because of financial constraints. In that period it produced many valuable resources, including workshop reports, guidelines and toolkits and training course resources. These are still available at the GISP website, although this site is no longer maintained and has some problems. They are also available on the ISSG website here.

I suggest you suppress this item and just add the GISP publications under LITERATURE. A lot of people don't know what GISP is or was, and it will be less relevant over time, so it does not seem to be a clear entry point.
