Mapping museum pest activity
Overview
• Problem facing Natural History Museum, London (NHM)• The solution• Review of Ke EMu
– Record creation– Record query– Analysing data
The situation
• IPM Committee with cross-museum representation
• Consistent and regular trapping in collection and exhibition areas
• Development of risk management approach using risk zones
The problem
• No centralised database for trapping data
– Inability to query and analyse the data
• Inconsistent departmental reports
– Unable to compare across the Museum
– Incoherent hard evidence
• Department-centric boundaries
– Individuals know situation within their area
– No strategic overview
GIS in the Literature
The solution
Record structure
• Pest trapping data consists essentially of two components:
– Data which describes the physical location of the trap
– Data which records the species diversity, and number of insects found within the trap at any point in time.

Query the data
• Increase in number of moths in the gallery spaces!
• Where?

Constructive criticism
• Support for multiple sites
• Support for temporal changes in the building infrastructure
• Display only the data queried for
• The ability to overlay additional data layers (e.g. risk zones)
• Ability to choose a fixed colour for a species for both charts and mapper.
• More control over the scaling key
Phase 2..?
Benefits
• Single, central repository for pest trapping data.
• Familiarity of the interface.
• Close association with specimen/collection information.
• Emulate professional GIS without complexity.
• Inform senior management based on evidence.
• Applicable to all EMu clients, but standardised for data interchange with non-EMu users.
Conclusion
• Spatial mapping provides a management tool:
– to remove the department-centric boundaries of conventional methods
– to more effectively monitor the overall situation
– to more effectively prioritise resources in reacting to situations
– to observe trends and patterns for pro-active measures
– to communicate the issues effectively
