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).
The PCOD v1.1 download available below contains the model and associated reports. The v1.1 update now includes a 'How To' guide and updated supporting documents. These can be downloaded separately.
Version 3.3 of the model can now be found on the Marine Scotland Information website.
