    "name": "2015-2016, SMRU Consulting, Dudgeon, Report on the distribution and abundance of harbour seals (Phoca vitulina) during the 2015 and 2016 breeding seasons in The Wash",
    "description": "This report presents the results of a series of aerial surveys of the harbour seal population along the English east coast between Donna Nook in Lincolnshire and Scroby Sands off the Suffolk coast during the breeding seasons from 16th June to 17th July 2015 and 19th June to 16th July 2016. \r\n- Five surveys were completed on the 16th, 21st and 27th June and 3rd and 17th July 2015.\r\n- Five surveys were completed on the 19th, 24th June and 2nd, 8th and 16th July 2016.\r\n- As usual, flights were restricted to weekends because of RAF range activity. Poor weather conditions on the weekend of 10th July 2015 prevented flying and delayed the final flight to the 17th July 2015. This had no negative effects on the results.\r\n- The highest count obtained in 2015 was 1351 on 27th June and in 2016 the highest count was 1580 on 2nd July. Examination of the series of counts suggests that this is close to the actual maximum number of pups for the season. Examination of the five survey counts in each year suggests that these are close to the actual maximum number of pups in each year.\r\n- The 2015 count was substantially lower (22%) than the 2014 equivalent count, but the 2016 peak count was 17% higher than in 2015. These wide fluctuations are not unusual in the long term time series.\r\n- Despite the apparently wide inter-annual variation, the pup production has increased at around 7.4% p.a. since surveys began in 2001.\r\n- The distribution of pup counts within The Wash has changed with more pups in the sheltered South East corner, and more along the banks of the main river channels. These changes appear to have happened between 2001 and 2010.\r\n- Pup productivity has apparently increased relative to the independent estimates of the total population size",
