Many of us attended a fantastic seminar on Friday the 17th of May, given by Dr Ed Barrrows – IUCN Red List of Ecosystems: An evolving tool for risk assessment, priority setting and landscape action. Dr Ed Barrows is a former graduate of Trinity’s Zoology Department and is currently the Head of Ecosystems at the IUCN. The focus of his talk was to introduce us to the new risk assessment criteria developed by the IUCN to assess ecosystems. This will ultimately provide the world with a Red List for Ecosystems. We were all familiar with the concept of a Red List for Species but this was the first time we had been introduced to concept of a standard global assessment of risks for entire ecosystems or “higher levels of biodiversity”. First we had a great introduction into the new ecosystem assessment tool developed by the IUCN. Ed brought us through the process behind the model and the need for such a tool. Incorporated in the model was the interesting concept that of ecosystem collapse. When does an ecosystem go beyond recovery and change into something else.
A well deserved cup of coffee and great pastries helped us to digest and process this information.
Following this, a number of the lucky ones who had signed up for the workshop traipsed over to the SNIAM building where we were in for a treat. Ed was hosting a two hour workshop to give us all some practical experience of applying the model and carrying out a risk assessment on an Irish ecosystem. There really was a great mix of people attending from permanent Trinity staff, post docs, master’s students, undergraduates and members of various NGO’s.
We were divided in to four groups. The model uses four distributional and functional symptoms to assess ecosystem risk. Two of the groups were to look at the criteria A & B (distributional) and the other two C & D (functional). Ed explained to us that the process of evaluating a habitat would normally take over four months and extensive amount of backing data. He then proceeded to tell us that we had two hours and two scientific papers with which to assess maybe one of the most politically sensitive habitats in Ireland “Peat lands”! A lively debate ensued as the two groups from each section gave their results and the reasons as to why they come to those conclusions. The final discussion looked at the fifth criterion which estimates the risk of ecosystem collapse and assigns it to critical, endangered or vulnerable – I think there are still people arguing over it…
