2012 red squirrel conservation effort Standardised recording by: RSNE Rangers and contractors Volunteer Groups Land managers 9000 records now held – 10 fields per record RAPID ANALYSIS IS ESSENTIAL FOR EFFECTIVE, MORAL & EFFICIENT CONSERVATION
Aim and Methodology • Manage and organise 9000 records • Duplicates, dates and grid references • Map making • Thematic mapping
Point based thematic maps • Best suited to small data sets • Large data sets and the issues they bring • Overlapping records • Loss of accuracy with the data ‘All squirrel sightings 1960-present’
Region based thematic maps • Easy to interpret • Summary of records per tetrad • Same scale unit as RSNE monitoring work • Capable of displaying large datasets • Next steps – 1. Further break down into regions/counties 2. Repeat for other data fields 3. Relate to range monitoring data Shown above ‘Grey kills per tetrad in 2012’
