Sample Area Number1
The plots within each sample area are linked to the sample area table by a unique number assigned to each entry in the
sample area table.

Plot Description Table
• Plot Size
Contains a description of each plot within each sample area number including:
• Elevation • Soil Type • Plot Number*
Plot Size 5m X 5m
Elevation 25 m
Plot Number 27
Access
• Within each plot, tables can be created to hold more specific data
• Data are linked by a unique plot number designated to each plot
entry
Plot Number
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 ListIn order to avoid problems with misspellings and inconsistency with names, a species list can be created. A species list can contain:
• Common Name • Scientific Name • Family• Species ID Number*

Expanding Beyond Agrobiodiversity:
• Management Data
• Socioeconomic Data
•Geographical Data
Adding Management Data
• Converting Descriptive or Qualitative Data into Discrete or Quantitative Data
• Organizing Tables that are Compatible with the PLEC Agrobiodiversity Database

Levels of Management Data
Some farmers transplant seedlings from the forest into their fallows
Transplanting
Some farmers add manure or chemical fertilizer to specific plots
ManureChemical Fertilizer
Some farmers occasionally clear the weeds around the base of select species
Weeding
Farmers water sample areas at different intervals
Watering per Year
Thinning per Year
Plowing
Clear Undergrowth
Pesticide
Date of Harvest

Creating Relationships and Analyzing Management Data
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
