    "name": "2007, Ecofys, Lincs Offshore Wind Farm, Collision Risk Modelling for Pink Footed Geese in the Greater Wash",
    "description": "This series focuses on the methods used and results generated by collision risk modelling for pink-footed geese in the greater Wash. \r\n\r\nIt is possible to estimate mortality rates of birds passing through a wind farm given key\r\nparameters of the placement, dimension and operation of the wind turbines and the\r\nmovements, abundance and behaviour of the birds. This has lead to the development of\r\ncollision risk models.\r\nFor an offshore site, the data to estimate the abundance (and movements) of the birds\r\nshould preferably come from boat-based surveys. In the boat-based surveys \u2018snapshots\u2019\r\nare used to quantitatively assess flying birds. Snapshots are predefined moments during\r\nthe survey at which all flying birds within a certain distance from the surveyor are recorded.\r\nFrom the snapshot data one can calculate the density of birds in flight (e.g. number\r\nof flying birds per square km).\r\nHowever, with Pink-footed geese (PG) there is a (potential) problem with this methodology.\r\nThis is due to the fact that very few PG have been recorded in snapshots. In the 19\r\nboat-based surveys for the offshore wind farms Lynn and Inner Dowsing (LID), only 5\r\nPG were recorded in snapshots during a single survey in November 2003. Similar results\r\nwere found in the boat-based surveys for the Lincs offshore wind farm: 54 PG in a single\r\nsurvey in September 2004, out of 33 boat-based surveys. During the boat-based surveys\r\nfor Docking Shoal OWF not a single PG was recorded in snapshots in any of the 39 surveys.\r\nThe statistical validity of collision risk modelling based on the incidental records of\r\nPink-footed geese in or near LID or Lincs is therefore questionable at best.\r\nThere is an alternative approach. The Pink-footed geese pass through the Greater Wash\r\nduring the migration to and from their overwintering ground in Norfolk. A reasonable estimate\r\nof the annual passage rate of PG through a wind farm site can be made on the basis\r\nof the maximum number of PG recorded overwintering in Norfolk, and some reasonable\r\nassumptions on the flight corridor along the Lincolnshire Coast. The maximum number of\r\nPG yet recorded in Norfolk is 152,514 ind. (recorded on 13th December 2004 - Norfolk\r\nand Norwich Naturalists\u2019 Society 2005).\r\n\r\nIn this report the results from both approaches are presented. It was found that compared to the mortality rates calculated based on the site specific boat-based surveys, the calculated total mortality rate based on the maximum regional population is about a factor of two higher.",
