Rookeries Survey 2010

© Garth PeacockThis year the CBC Research Committee would like to collect data on every Rookery in the county.  This can be achieved if as many members as possible record simple information for every Rookery they find this spring.  Ideally we would like all data to be submitted on the Excel sheet available from the club website and this format is used in the example below.  If you do not have access to the internet then paper records in the same format can be sent to Louise Bacon (see the last page for contact details).

The 6 figure grid reference is generated.  To make data analysis and map generation as unambiguous as possible we would ask that all grid references are generated using from the GrabaGrid website, using the 100m square function which is also linked on the club website.  The data gathered will be used for the BTO Atlas, the planned Cambridgeshire Atlas and for a Research Committee paper comparing the 2010 data with the historic database of previous surveys co-ordinated by Graham Easy. Completed Rookeries Excel sheets should be sent via e-mail to at the end of May.
