Description

A population viability analysis of the North Norfolk Sandwich tern (Sterna sandvicensis) 
population was undertaken by Centrica Renewables at the request of Natural England, to understand potential impacts of
estimated collision at Centrica’s Docking Shoal and Race Bank proposed offshore wind farms in the
Greater Wash, with a third consented site, Sheringham Shoal (SCIRA) included in background mortality.
The model developed specifically for the purpose, ViaPop, is an individual-based model with the potential
to understand the relative effects of different population parameters (ie sensitivity analysis) at greater
depth and sophistication than an off-the-shelf package. Population parameters were determined directly
from the data on the relatively well-studied north Norfolk colonies coupled with estimates of some
parameters from the literature, with estimates of survival rate determined by a specific analysis of British
Trust for Ornithology ring recovery data. A project board of experts in the field approved the use of the
different parameters used in ViaPop. The analysis was presented as suplementary information to the environmental statement.
