Plot Number
• Data are linked by a
unique plot number
designated to each plot
entry
• Within each plot, tables
can be created to hold more
specific data
Access
Species Data
Data can be recorded on
individuals and species within
each plot, including:
• Abundance of Species
• DBH and Height of Trees
• Species Utility
• Species ID Number*
Access
Species List
In order to avoid problems with misspellings and inconsistency with
names, a species list can be created. A species list can contain:
• Species ID Number* • Common Name • Scientific Name • Family

Adding GPS to an Access Database
• Coordinates can be added at either
the Sample Area or Plot level
• Queries can be linked to a GIS program
and will actively update analysis as data
are changed in Access
