Indian Forestry
•
•
Twelve regions nationally
Basically have three versions of the data
conversion utility for plot data
- Eastern US
- Western US (except the Northwest)
- Northwest Region
•
Conversion utilities for stand level inventories
Forest Inventories in
Indian Country
• 320 forested reservations
- Largest 5.3 million acres
- Smallest is 3 acres
• 81 reservations with permanent plot inventories (CFI)
• Other reservations with significant forest acres have
temporary plot inventories
• Minor forested reservations have temporary plot
inventories or stand level inventories
• Most reservations have stand level inventory
Role of the
Branch of Forest Resources Planning
• Assist in the measurement of the inventory
• When requested, process the field data
- Regression analysis
- Volume calculations
- Create FVS-ready data files
• Deploy analysis package to reservation
• Train field staff on applications
• The objective is to put the tools into the hands of the
field foresters
Use of FVS in Inventory Analysis
• Used in conjunction with standard BIA
analysis suite
- Inventory is first benchmarked using the BIA programs
• Determines the current condition of forest
• Measured trends on forest
• Monitor of management practices
• Used in modeling management alternatives,
calculation of allowable cut
Data Conversion Utility
• Creates Tree Files for FVS
- ASCII Text file format
- Tree files generated for all measurement intervals
- Three versions of tree files created
• Gross volumes – allows for the problem fields to be used for
other uses such as DMR
• Net volumes – uses two problem fields for cubic and board
defect
• “Special” dataset – used to combine defect (cubic) and tree
problem
Data Conversion (con’t)
• SLF files are generated using plot level data
from the inventory
- Can be programmed to use most current data or the data
collected at time of measurement
- Grouping fields are programmed for each reservation
Text Files vs. Database
• Programming the generation of text files
allows for more control over the coding of
data fields
- Conversion of CFI codes to FVS
- Special codes used in problem fields

Presuppose
• Special sorting is done through Presuppose
- Allows for the generation of FVS run based on any plot level
information
• Develops a sort file that can be used in the
BIA CFI applications along with the FVS
analysis
