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

• 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

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*

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
