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
