Final Report October 2011 for the BBI-Matra/2008/015 ... - Vlindernet

Activity outputs and additional benefits
Problems encountered
Extensive manual correction and completion of data was needed because a) the data in the
book was not presented consistently, b) there were data gaps and c) because the locations
given in the book were vague. This work was scheduled to be completed by the end of May
2009 but lasted until April 2010. In order to avoid long delays to the Red Listing process the
scarcer species were worked on first (c16,000 records) so that the data for these species
would be ready for the Red List Workshop in August. This was achieved.
Involving volunteers and short-term staff in data management in an effort to get the work
done created further data errors, problems with consistency and continuity, and extra work
for staff.
In April 2010 revised distribution maps were produced for more than 370 species.
In November-December 2010, further updates were made to the data for threatened species and new maps were
produced for the 38 species with detailed assessments in the Red Book.
The final data set, as used for the Red Book, comprised more than 70,800 records, divided between few Excel
spreadsheets:
� the Hesselbarth et al data set (up to 1995) 55,700 records;
� DKM survey data (2008-09) 7,500 records;
� literature and butterfly watchers (1995-2010), 7,600 records;
� Province-level data of around 5,000 records.

Despite the delays, those outputs which depended on the data – the Red Book, PBA and Conservation Strategy –
were all completed and published before the end of the project.
