Indian ForestryTwelve regions nationallyBasically have three versions of the data conversion utility for plot dataEastern US Western US (except the Northwest)Northwest RegionConversion utilities for stand level inventories

Forest Inventories in Indian Country320 forested reservationsLargest 5.3 million acresSmallest is 3 acres81 reservations with permanent plot inventories (CFI)Other reservations with significant forest acres have temporary plot inventoriesMinor forested reservations have temporary plot inventories or stand level inventoriesMost reservations have stand level inventory

Role of theBranch of Forest Resources PlanningAssist in the measurement of the inventoryWhen requested, process the field dataRegression analysisVolume calculationsCreate FVS-ready data filesDeploy analysis package to reservationTrain field staff on applicationsThe objective is to put the tools into the hands of the field foresters

Use of FVS in Inventory AnalysisUsed in conjunction with standard BIA analysis suiteInventory is first benchmarked using the BIA programs Determines the current condition of forestMeasured trends on forestMonitor of management practicesUsed in modeling management alternatives, calculation of allowable cut

Data Conversion UtilityCreates Tree Files for FVSASCII Text file formatTree files generated for all measurement intervalsThree versions of tree files createdGross volumes allows for the problem fields to be used for other uses such as DMRNet volumes uses two problem fields for cubic and board defectSpecial dataset used to combine defect (cubic) and tree problem

Data Conversion (cont)SLF files are generated using plot level data from the inventoryCan be programmed to use most current data or the data collected at time of measurementGrouping fields are programmed for each reservation

Text Files vs. DatabaseProgramming the generation of text files allows for more control over the coding of data fieldsConversion of CFI codes to FVSSpecial codes used in problem fields

Inventory Package Folder Structure

Linking it all together

PresupposeSpecial sorting is done through PresupposeAllows for the generation of FVS run based on any plot level informationDevelops a sort file that can be used in the BIA CFI applications along with the FVS analysis
