Metadata: 2004-2006, BTO, Greater Gabbard, The Potential Effects on Birds
Abstract:
Greater Gabbard Winds Ltd (GGOWL) has contracted the British Trust for Ornithology (BTO) and Environmentally Sustainable Systems (ESS) to undertake surveys and to assess the impacts of the proposed wind farm on bird populations. The North Sea and Suffolk coast are important areas for many waterbirds including divers, seaducks, gulls and auks. Offshore surveys were carried out between February 2004 and April 2006 to asertain the abundance and distribution of birds in the "footprint" area of the proposed wind farm, plus an extended "reference" survey area. Aerial and boat surveys were used in accordance with COWRIE recommendations. Centre for Marine and Coastal Studies Ltd (CMACS) was commissioned by Greater Gabbard Offshore Wind Limited (GGOWL) to analyse marine mammal sightings data collected by ESS Ltd during site-specific surveys of the proposed offshore wind farm development area. These data were used to support the project baseline description of marine mammals and the subsequent environmental impact assessment. The purpose of this report is to provide the marine mammal sightings data. Survey methods and all analyses used to inform the marine mammals baseline and to support the impact assessment are detailed in the environmental statement (GGOWL 2005).

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | GGOWL has contracted the British Trust for Ornithology (BTO) and Environmentally Sustainable Systems Ltd. (ESS) to undertake surveys and to assess the impacts of the proposed wind farm on bird populations. Boat-based bird surveys aimed to establish the numbers, distributions, flight heights and directions of birds found to be present within the study area (two wind farm sites, a surrounding buffer zone and two control areas) as well as to create a repeatable baseline for future monitoring requirements. Between February and March 2004, the study area surveyed encompassed 487 km2 over 10 transects. The entire study area from April 2004 spanned 730 km2, comprising the wind farm footprint, and the reference area comprising the surrounding buffer zone and two control areas, over nine transects. The area of study was changed in accordance with revisions to the location and alignment of the proposed wind farm. For both areas, surveys were spread over on consecutive days, where weather allowed. The field methods used were adapted from Counting Birds from Boats (Webb, in Komdeur et al. 1992) and have been developed to maximise accuracy, repeatability, and suitability for two observers. They remain consistent with COWRIE recommendations (Camphuysen et al. 2004). Transects were spaced at 1.8 km intervals, running parallel to the coast for the first three surveys, and perpendicular to the coast, spaced 2 km apart thereafter (see Figures 1.2-1 and 1.2-2), and also conform to COWRIE recommendations. Five survey blocks, labelled TH1 – TH5, were covered four times during the winter of 2004/05 (Figure 1.2-3) by surveyors of the Wildfowl & Wetlands Trust Wetlands Advisory Service, the area containing the proposed Greater Gabbard wind farm being TH3. In the winter of 2005/06, two of the areas counted in 2004/05 (TH4 and TH5) were not counted, but two additional areas (TH6 and TH7) were counted instead. Thirteen line transects were surveyed within TH3, 10 of length 42 km and three of 44 km (Table 2.1.2-1). The total area surveyed was 1,060 km2. For area TH3, the following dates were used for the first set of surveys: winter period 1 = 12/11/04; winter period 2 = 24/11/04; winter period 3 = 14/01/05; winter period 4 = 28/02/05, and the following dates used for the second set of survey: winter period 1 = 16/11/05; winter period 2 = 08/12/05; winter period 3 = 10/02/06; winter period 4 = 03/03/06. |
