2009, COWRIE, A Review of Assessment Methodologies for rnOffshore Windfarms (Birds)

Description

COWRIE previously published guidelines for ship and aerial survey of marine birds for
offshore windfarm assessments (Camphuysen et al. 2004). The purposes of the current
review are fourfold:
a. to assess the extent to which these recommendations have been followed;
b. to identify any differences in interpretation of the guidance between sites;
c. to test the practicalities of using high definition cameras during aerial surveys;
d. to provide more rigorous guidelines for the type of analytical techniques that
should be used.
The BTO and COWRIE undrtook a desk based study using datasets obtained from previous COWRIE surveys.
