Sustainable Aggregates Creating Environmental Improvements <strong>through</strong> Biodiversity<br />

Project Type: GIS analysis<br />

Site: numerous sites <strong>through</strong>out Great Britain<br />

Project Aim:<br />

To attempt to discover if relationships (identified on some sites in the previous two reports) could be found<br />

between the physical and botanical characteristics of lakes and the numbers of waterfowl using them, in a<br />

larger sample of former mineral extraction sites<br />

To attempt to discover key morphological characteristics of water bodies that could be used to predict bird<br />

numbers<br />

Main Methods:<br />

Analysis of simple relationships between water body size and shape (on former mineral extraction sites), and<br />

types of bird using the habitat<br />

Data on mineral extraction sites from British Geological Survey (BGS) combined onto a map with counts<br />

from the Wetland Bird Survey (WeBS), using ArcView GIS<br />

WeBS data divided and dealt with in two separate databases - summer and winter<br />

Digital mapping of individual lakes to assemble data on lake area, perimeter length, and number of islands<br />

Correlation of lake characteristics with total numbers of waterfowl, and total numbers of different waterfowl<br />

guilds (swans, geese, dabbling duck, diving duck, sawbills), to assess determining factors<br />

Principle components analysis used to further test results<br />

Regression analysis of likely total number of waterfowl to be found on a given pit<br />
