Interim Population Consequences of Disturbance Model (iPCOD)

Please Note A bug was found in the code. As a consequence, we have withdrawn the download while the issues are being examined. A new version will be published in due course. Marine Scotland will retain a copy of the code, but does not recommend using it.

This model, written in R, is a protocol for implementing an interim version of the Population Consequences of Disturbance (PCoD) approach for assessing and quantifying the potential consequences for marine mammal populations of any disturbance and/or injury that may result from offshore energy developments. It has been designed to use the kinds of information that are likely to be provided by developers in their Environmental Statements and Habitats Regulations Assessments.

We emphasise the interim nature of this approach, which was developed to deal with the current situation, where there is limited data on the way in which changes in behaviour and hearing sensitivity may affect the ability of individual marine mammals to survive and to reproduce.

The model allows the user to predict the population consequences of disturbance on five key priority species of marine mammal found in the UK (Bottlenose dolphins, Harbour porpoise, Minke whale, Harbour and Grey seals).
