JNCC report series

This report outlines the methods used during the 2006/07 winter and spring aerial surveys of selected Scottish inshore water areas and shore-based counts of Aberdeen Bay, and presents the recorded numbers and diurnal distributions of the species observed in each survey area.

This report provides a shared and improved understanding of the current status and distribution in Guinea of diurnal and nocturnal raptors on which to base assessments of the sustainability of any trade.

This report supports an accompanying Geographical Information System (GIS) project (manx1.mxd) that holds the datasets gathered during this survey work. The report identifies a number of biotopes and sediment types in the survey area and justifies the selection of these biotope classifications with illustrative data.

JNCC invited representatives from a range of organisations to a workshop in Peterborough on the 1-2 May, 2007 to discuss the identification, management and monitoring of Sabellaria spinulosa reefs.

Ozone is globally the most important gaseous pollutant causing effects on vegetation. While a number of reviews have evaluated the evidence of impacts of ozone on semi-natural ecosystems, none of these has specifically focussed on the priorities of nature conservation agencies.

Data from boat and aerial surveys of Tay Bay carried out over five winter seasons (1997/98, 2000/01, 2001/02, 2003/04 and 2004/05) are described in this report. One boat survey carried out during 1997/98 was conducted using line transect sampling techniques; for this survey, the data were analysed using extrapolation of raw counts to estimate the total numbers of birds using the survey area. Two aerial surveys carried out during 2000/01 were conducted using strip-transect methods, and the data from these are total counts of birds using the area surveyed. Seven aerial surveys during the latter three seasons were conducted using line-transect sampling techniques; for these, the data were analysed where possible, using distance sampling, to estimate the total numbers of birds using the area surveyed.

The Wildlife and Pollution contract supports the long-term monitoring programme called the Predatory Bird Monitoring Scheme (PBMS) which monitors selected pollutants, pesticides and biocides in predatory birds in Britain. The programme was started in the early 1960s and was instrumental in securing the phased withdrawals of the permitted uses of organochlorine (OC) insecticides. It has since provided a measure of the effectiveness of regulatory bans in reducing the exposure of wildlife.

The programme was started in the early 1960s, when there were serious concerns over the effects of organochlorine insecticides and organomercury fungicides on various species of birds and mammals.

This report covers BTO work under the Partnership during 2005/2006, including much collation and analysis of data collected in previous years.

This report assesses the significance of British Lowland Grasslands, occurring below the line of enclosure or moorland wall, with a wider European frame.
