Offshore Wind Farm (OWF) site, and associated control Zones, for birds and marine mammals. Construction of the Phase 1 area of the London Array Ltd. OWF commenced in March 2011 and is due to be completed by the end of 2012. The aerial surveys are designed to meet the requirements of the Marine Licence granted in respect of the wind farm, and to satisfy the wider Ornithological Review Panel (ORP) process. The ORP was set up prior to award of consent as an expert panel comprising representatives from London Array, Natural England and Royal Society for Protection of Birds (RSPB) to discuss and agree the scope of the ornithological monitoring required under the phased approach in the London Array Marine Licence, and to agree an interaction figure that would not have an adverse effect on integrity of the likely Greater Thames Estuary Special Protection Area (SPA). In order to satisfy Marine Licence conditions, during construction monitoring for Phase 1 development and pre-construction monitoring of Phase 2 is required, necessitating aerial survey of the London Array OWF site and a control Zone. Aerial surveys designed to fulfil the ORP process cover further control Zones.

Four surveys of six survey Zones were completed in total, with one survey conducted each month. Each survey was flown on a 500 m grid at a 3 cm Ground Sampling Distance (GSD) resolution to ensure comparability with the 2010 / 11 pre-construction surveys (for detailed rationale, see APEM (2010)). The primary aim of APEM’s grid survey methodology is to derive sufficient independent estimates of bird density (and distribution) to target a predefined level of precision around population estimates. The coarseness (spacing) of the grid (an image is collected at each grid internode) is determined by the predicted number of samples required to achieve the predefined level of confidence. Aerial surveys were undertaken using either a Vulcanair P68 Observer twin engine survey aircraft or a Britten-Norman Islander survey aircraft.
