FEATURE ATTRIBUTE TABLES CODES AND VALUES:
Item | Item Description | |
Shape |
Feature geometry. |
|
OBJECTID |
Internal feature number. |
|
CNTY_PLT |
County Plot Number. Unique identifier for every FIA plot in the state. First 1 to 3 digits refer to the county FIPS code and the last three digits refer to the Plot Number (see PLOT item below). |
|
INVYR |
Inventory year. The year that best represents when the inventory data selected each year for sampling. The selection is based on a panel INVYR is the year in which the majority of plots in that group were collected (plots in the group have the same panel and, if applicable, subpanel). Under periodic inventory, a reporting inventory year was selected, usually based on the year in which the majority of the plots were collected or the mid-point of the years over which the inventory spanned. For either annual or periodic inventory, INVYR is not necessarily the same as MEASYEAR. |
|
STATECD |
State code. Bureau of the Census Federal Information Processing Standards (FIPS) two-digit code for each State. |
|
UNITCD |
Survey unit code. Forest Inventory and Analysis survey unit identification number. Survey units are usually groups of counties within each State. For periodic inventories, Survey units may be made up of lands of particular owners.
|
|
COUNTYCD |
County code. The identification number for a county, parish, watershed, borough, or similar governmental unit in a State. FIPS codes from the Bureau of the Census are used. |
|
PLOT |
Phase 2 plot number. An identifier for a plot. Along with STATECD, INVYR, UNITCD, COUNTYCD and/or some other combinations of variables, PLOT may be used to uniquely identify a plot. |
|
STATUS_CD |
Plot status code. A code that describes the sampling status of the plot. Blank (null) values may be present for periodic inventories.
|
|
NO_SAMP_CD |
Plot nonsampled reason code. For entire plots that cannot be sampled, one of the following reasons is recorded.
|
|
REMPER |
Remeasurement period. The number of years between measurements for remeasured plots. This attribute is null (blank) for new plots or remeasured plots that are not used for growth, removals, or mortality estimates. For data processed with NIMS, REMPER is the number of years between measurements (to the nearest 0.1 year). For data processed with systems other than NIMS, remeasurement period is based on the number of growing seasons between measurements. Allocation of parts of the growing season by month is different for each FIA program. Contact the appropriate FIA program for information on how this is done for a particular State. NOTE: it is not valid to use REMPER to estimate periodic change. |
|
RDDISTCD |
Horizontal distance to improved road code. The straight-line distance from plot center to the nearest improved road, which is a road of any width that is maintained as evidenced by pavement, gravel, grading, ditching, and/or other improvements. Populated for all forested plots using the National Field Guide protocols (MANUAL >= 1.0) and populated by some FIA work units for inventory plots collected where MANUAL < 1.0.
|
|
WATERCD |
Water on plot code. Water body less than 1 acre in size or a stream less than 30 feet wide that has the greatest impact on the area within the forest land portion of the four subplots. The coding hierarchy is listed in order from large permanent water to temporary water. Populated for all forested plots using the National Field Guide protocols (MANUAL>=1.0) and populated by some FIA work units for inventory plots collected where MANUAL < 1.0.
|
|
LAT |
Latitude. The approximate latitude of the plot in decimal degrees using NAD 83 datum. Actual plot coordinates cannot be released because of a Privacy provision enacted by Congress in the Food Security Act of 1985. Therefore, this attribute is approximately +/- 1 mile and, for annual inventory data, most plots are within +/- mile. Annual data have additional uncertainty for private plots caused by swapping plot coordinates for up to 20% of the plots. In some cases, the county centroid is used when the actual coordinate is not available. |
|
LON |
Longitude. The approximate longitude of the plot in decimal degrees using NAD 83 datum. Actual plot coordinates cannot be released because of a Privacy provision enacted by Congress in the Food Security Act of 1985. Therefore, this attribute is approximately +/- 1 mile and, for annual inventory data, most plots are within +/- mile. Annual data have additional uncertainty for private plots caused by swapping plot coordinates for up to 20% of the plots. In some cases, the county centroid is used when the actual coordinate is not available. |
|
ELEV |
Elevation. The distance the plot is located above sea level, recorded in feet (NAD 83 datum). Negative values indicate distance below sea level. |
|
ECOSUBCD |
Ecological subsection code. An area of similar surficial geology, lithology, geomorphic process, soil groups, subregional climate, and potential natural communities. Subsection boundaries usually correspond with discrete changes in geomorphology. Subsectioninformation is used for broad planning and assessment. Subsection codes may consist of up to six characters and were developed by the Forest Service as part of the National Hierarchical Framework of Ecological Units (Cleland and others 2005) (visit http://svinetfc4.fs.fed.us/clearinghouse/other_resources/other_resources.html ). The ECOSUBCD is based on fuzzed and swapped plot coordinates. This attribute is coded for the coterminous States and southeast Alaska, and is left blank (null) in all other instances. For more information about the coverage used to assign this attribute, see USDA Forest Service ECOMAP Team (2005). |
|
MANUAL |
Manual (field guide) version number. Version number of the Field Guide used to describe procedures for collecting data on the plot. The National FIA Field Guide began with Version 1.0; therefore data taken using the National Field procedures will have PLOT.MANUAL >=1.0. Data taken according to field instructions prior to the use of the National Field Guide have PLOT.MANUAL < 1.0. |
|
EXPNS |
Expansion factor. The area, in acres, that a stratum represents divided by the number of sampled plots in that stratum. This attribute can be used to obtain estimates of population area when summed across all the plots in the population of interest. Refer to chapter 4 for detailed examples. |
|
PLT_CN |
Sequence number. A unique sequence number used to identify a plot record. |
|
RESERVCD |
Reserved status code. (Core for accessible forestland; Core optional for all sampled land.) Reserved land is land that is withdrawn by law(s) prohibiting the management of the land for the production of wood products.
|
|
OWNCD |
Owner class code. (Core for all accessible forestland; Core optional for all sampled land.) A code indicating the class in which the landowner (at the time of the inventory) belongs. When PLOT.DESIGNCD = 999, OWNCD may be blank (null).
|
|
FORTYPCD |
Forest type code. This is the forest type used for reporting purposes. It is primarily derived using a computer algorithm, except when less than 25 percent of the plot samples a particular forest condition. Usually, FORTYPCD equals FORTYPCDCALC. In certain situations, however, the result from the algorithm (FORTYPCDCALC) is overridden by the field call. The field-recorded forest type code (FLDTYPCD) is stored in this attribute when less than 25 percent of the plot samples the forested condition (CONDPROP_UNADJ < 0.25). Situations of undersampling may cause this attribute to differ from FORTYPCDCALC. Nonstocked forest land is land that currently has less than 10 percent stocking but formerly met the definition of forest land. Forest conditions meeting this definition have few, if any, trees sampled. In these instances, the algorithm cannot assign a specific forest type and the resulting forest type code is 999, meaning nonstocked.
|
|
STDAGE |
Stand age. For annual inventories (PLOT.MANUAL > 1.0), stand age is equal to the field-recorded stand age (FLDAGE) with some exceptions. One exception is if FLDAGE = 999, then stand age is computed. When FLDAGE = 998, STDAGE is blank (null) because no trees were cored in the field. Another exception is that RMRS always computes stand age using field recorded tree ages from trees in the calculated stand size class. If no tree ages are available, then RMRS sets this attribute equal to FLDAGE. For all inventories, nonstocked stands have STDAGE set to 0. In periodic inventories, stand age is determined using local procedures. Annual inventory data will contain stand ages assigned to the nearest year. For some older inventories, stand age was set to 10-year classes for stands < 100 years old, 20-year age classes for stands between 100 and 200 years, and 100-year age classes if older than 200 years. These classes were converted to store the midpoint of the age class in years. Blank (null) values in the periodic data (PLOT.MANUAL < 1.0) indicate that the stand was recorded as mixed age on forested condition classes. Age is difficult to measure and therefore STDAGE may have large measurement errors. |
|
STDSZCD |
Stand-size class code. A classification of the predominant (based on stocking) diameter class of live trees within the condition assigned using an algorithm. Large diameter trees are at least 11.0 inches diameter for hardwoods and at least 9.0 inches diameter for softwoods. Medium diameter trees are at least 5.0 inches diameter and smaller than large diameter trees. Small diameter trees are less than 5.0 inches diameter. When less than 25 percent of the plot samples the forested condition (CONDPROP_UNADJ < 0.25), this attribute is set to the equivalent field-recorded stand size class (FLDSZCD). Populated for the NCRS periodic plots that were measured as "nonforest with trees" (e.g., wooded pasture, windbreaks).
|
|
SITECLCD |
Site productivity class code. A classification of forest land in terms of inherent capacity to grow crops of industrial wood. Identifies the potential growth in cubic feet/acre/year and is based on the culmination of mean annual increment of fully stocked natural stands. For data stored in the database that were processed outside of NIMS, this variable may be assigned based on the site productivity determined with the site trees, or from some other source, but the actual source of the site productivity class code is not known. For data processed with NIMS, this variable may either be assigned based on the site trees available for the plot, or, if no valid site trees are available, this variable is set equal to SITECLCDEST, a default value that is either an estimated or predicted site productivity class. If SITECLCDEST is used to populate SITECLCD, the variable ITECL_METHOD is set to 6.
|
|
SICOND |
Site index for the condition. This represents the average total length in feet that dominant and co-dominant trees are expected to attain in well stocked, even-aged stands at the specified base age (SIBASE). Site index is estimated for the condition by either using an individual tree or by averaging site index values that have been calculated for individual site trees (see SITETREE.SITREE) of the same species (SISP). As a result, it may be possible to find additional site index values that are not used in the calculation of ICOND in the SITETREE tables when site index has been calculated for more than one species in a condition. This attribute is blank (null) when no site index data are available. |
|
SIBASE |
Site index base age. The base age (sometimes called reference age), in years, of the site index curve used to derive site index. Base age may be breast height age or total age, depending on the specifications of the site index curves being used. This attribute is blank (null) when no site tree data are available. |
|
SISP |
Site index species code. The species upon which the site index is based. In most cases, the site index species will be one of the species that define the forest type of the condition (FORTYPCD). In cases where there are no suitable site trees of the type species, other suitable species may be used. This attribute is blank (null) when no site tree data are available. |
|
STDORGCD |
Stand origin code. Method of stand regeneration for the trees in the condition. An artificially regenerated stand is established by planting or artificial seeding. Populated for the NCRS periodic plots that were measured as "nonforest with trees" (e.g., wooded pasture, windbreaks
|
|
STDORGSP |
Stand origin species code. The species code for the predominant artificially regenerated species (only when STDORGCD = 1) May not be populated for some units when PLOT.MANUAL < 1.0.
|
|
SLOPE |
Slope. The angle of slope, in percent, of the condition. Valid values are 000 through 155 for data collected when PLOT.MANUAL >1.0, and 000 through 200 on data collected when PLOT.MANUAL <1.0. When PLOT.MANUAL < 1.0, the field crew measured condition slope by sighting along the average incline or decline of the condition. WhenPLOT.MANUAL > 1.0, slope is collected on subplots but no longer collected for conditions. When PLOT.MANUAL > 1.0, the slope from the subplot representing the greatest percentage of the condition will be assigned as a surrogate. In the event that two or more subplots represent the same amount of area in the condition, the slope from the lower numbered subplot is used. Populated for the NCRS periodic plots that were measured as "nonforest with trees" (e.g., wooded pasture, windbreaks). |
|
ASPECT |
Aspect. The direction of slope, to the nearest degree, for most of the condition. North is recorded as 360. When slope is less than 5 percent, there is no aspect and this item is set to zero. When PLOT.MANUAL < 1.0, the field crew measured condition aspect. When PLOT.MANUAL > 1.0, aspect is collected on subplots but no longer collected for conditions. NOTE: for plots measured when PLOT.MANUAL > 1.0, the aspect from the subplot representing the greatest percentage of the condition will be assigned as a surrogate. In the event that two or more subplots represent the same percentage of area in the condition, the slope from the lower numbered subplot is used. Populated for the NCRS periodic plots that were measured as "nonforest with trees" (e.g., wooded pasture, windbreaks). |
|
PHYSCLCD |
Physiographic class code. The general effect of land form, topographical position, and soil on moisture available to trees. These codes are new in annual inventory; older inventories have been updated to these codes when possible. Populated for the NCRSperiodic plots that were measured as "nonforest with trees" (e.g., wooded pasture, windbreaks).
|
|
GSSTKCD |
Growing-stock stocking code. A code indicating the stocking of the condition by growing-stock trees, including seedlings. Growing-stock trees are those where tree class (TREE.TREECLCD) equals 2 and species group (TREE.SPGRPCD) is equal to other than 23 (western woodland softwoods), 43 (eastern noncommercial hardwoods), and 48 (western woodland hardwoods). Populated for the NCRS periodic plots that were measured as "nonforest with trees" (e.g., wooded pasture, windbreaks).
|
|
ALSTKCD |
All live stocking code. A code indicating the stocking of the condition by live trees, including seedlings. Data are in classes as listed for GSSTKCD. May not be populated for some units when PLOT.MANUAL < 1.0. Populated for the NCRS periodic plots that were measured as "nonforest with trees" (e.g., wooded pasture, windbreaks). |
|
DSTRBCD1 |
Disturbance 1 code. A code indicating the kind of disturbance occurring since the last measurement or within the last 5 years for new plots. The area affected by the disturbance must be at least 1 acre in size. A significant level of disturbance (mortality or damage to 25 percent of the trees in the condition) is required. Populated for all forested conditions using the National Field Guide protocols (PLOT.MANUAL ? 1.0) and populated by some FIA work units where PLOT.MANUAL < 1.0. Codes 11, 12, 21, 22, and 55 are valid where PLOT. MANUAL > 2.0.
|
|
DSTRBYR1 |
Disturbance year 1. Year in which Disturbance 1 is estimated to have occurred. If the disturbance occurs continuously over a period of time, the value 9999 is used. Populated for all forested conditions using the National Field Guide protocols (PLOT.MANUAL ? 1.0) and populated by some FIA work units where PLOT.MANUAL < 1.0. |
|
TRTCD1 |
Stand Treatment 1 code. A code indicating the type of stand treatment that has occurred since the last measurement or within the last 5 years for new plots. The area affected by the treatment must be at least 1 acre in size. Populated for all forested conditions using the National Field Guide protocols (PLOT.MANUAL >= 1.0) and populated by some FIA
|
|
TRTYR1 |
Treatment year 1. Year in which Stand Treatment 1 is estimated to have occurred Populated for all forested conditions using the National Field Guide protocols (PLOT.MANUAL ? 1.0) and populated by some FIA work units where PLOT.MANUAL < 1.0. |
|
PRESNFCD |
Present nonforest code. A code indicating the kind of land use occurring now for conditions that were previously classified as forest but are now classified as nonforest. Populated when PLOT.MANUAL > 1.0 and COND_STATUS_CD = 2. May be populated when PLOT.MANUAL < 1.0. *These codes are currently regional. They will become national in PLOT.MANUAL = 5.0.
|
|

|
CARB_LIT |
Carbon in litter. Carbon in organic material on the floor of the forest, including fine woody debris, humus, and fine roots in the organic forest floor layer above mineral soil. Calculated carbon density (tons per acre) based on region, forest type and stand age (Smith and Heath 2002). |
|

|
CARB_STA_D |
Carbon in standing dead. For the periodic inventories, carbon in standing dead trees, including coarse roots is calculated based on forest type and live tree carbon (this also applies to all estimates for 1 to 5 inch trees) (Jenkins and others 2003, Smith and Heath in prep). This field is blank (null) for annual inventories where individual-tree data are available. For annual inventories carbon density (tons per acre) is calculated using tree-level data. |

The information contained in this dataset is a subset of the information available within the larger Forest Inventory and Analysis Database (FIADB) available at http://fiatools.fs.fed.us/fiadb-downloads/datamart.html. To use the FIADB effectively, users should acquire a basic understanding of FIA sampling and estimation procedures provided in the Forest Inventory and Analysis Database: Database Description and Users Manual Version 4.0 for Phase 2 available at http://fia.fs.fed.us/library/database-documentation/ |
The FIA Program of the U.S. Forest Service provides the information needed to assess America's forests. As the Nation's continuous forest census, the FIA program projects how forests are likely to appear 10 to 50 years from now. This enables the USDA forest Service to evaluate whether current forest management practices are sustainable in the long run and to assess whether current policies will allow the next generation to enjoy America's forests as we do today. |

GeoPlan downloaded the data via the FIA DataMart located at http://fiatools.fs.fed.us/fiadb-downloads/datamart.html in comma delimited format (.csv). (1) Datasets within the Forest Inventory and Analysis database utilized were the FL_PLOT.CSV, FL_COND.CSV, and FL_POP_STRATUM.CSV files. (2) The CSV tables were converted to .DBF format and joined to the FL_PLOT table based on the plot identifier number. (3) The newly joined table was exported and converted to a shapefile using the add XY tool in ArcMAP. (4) The shapefile was projected from WGS 1984 to FGDL Albers and renamed to flfia09.shp (5) The following fields were changed, added, or dropped from the FL_PLOT.CSV table; Field ----------------------------------Dropped(Y/N)---------------------New Field CN N PLT_CN SRV_CN Y N/A CTY_CN Y N/A PREV_PLT_CN Y N/A INVYR N SAME STATECD N SAME UNITCD N SAME COUNTYCD N SAME PLOT N SAME PLOT_STATUS_CD N SATUS_CD PLOT_NONSAMPLE_REASN_CD N NO_SAMP_CD MEASYEAR Y N/A MEASMON Y N/A MEASDAY Y N/A REMPER N SAME KINDCD Y N/A DESIGNCD Y N/A RDDISTCD N SAME WATERCD Y N/A LAT N SAME LON N SAME ELEV N SAME GROW_TYP_CD Y N/A MORT_TYP_CD Y N/A P2PANEL Y N/A P3PANEL Y N/A ECOSUBCD N SAME CONGCD Y N/A MANUAL N SAME SUBPANEL Y N/A KINDCD_NC Y N/A QA_STATUS Y N/A CREATED_BY Y N/A CREATED_DATE Y N/A (6) The following fields were changed, added, or dropped from the FL_COND.CSV table; Field ----------------------------------Dropped(Y/N)---------------------New Field CN Y N/A PLT_CN Y N/A INVYR Y N/A STATECD Y N/A UNITCD Y N/A STATECD Y N/A UNITCD Y N/A COUNTYCD Y N/A PLOT Y N/A COND_ID Y N/A COND_STATUS_CD Y N/A CON_NONSAMPLE_REASN_CD Y N/A RESERVCD N SAME OWNCD N SAME OWNGRPCD Y N/A FORINDCD Y N/A ADFORCD Y N/A FORTYPCD N SAME FLDTYPCD Y N/A MAPDEN Y N/A STDAGE N SAME STDSZCD N SAME FLDSZCD Y N/A SITECLCD N SAME SICOND N SAME SIBASE N SAME SISP N SAME STDORGCD N SAME STDORGSP N SAME PROP_BASIS Y N/A CONDPROP_UNADJ Y N/A MICRPROP_UNADJ Y N/A SUBPPROP_UNADJ Y N/A MACRPROP_UNADJ Y N/A SLOPE Y N/A ASPECT Y N/A PHYSCLCD N SAME GSSTKCD N SAME ALSTKCD N SAME DSTRBCD1 N SAME DISTRYR1 N SAME DSTRBCD2 Y N/A DSTRBYR2 Y N/A DSTRBCD3 Y N/A DSTRBYR3 Y N/A TRTCD1 N SAME TRTYR1 N SAME TRTCD2 Y N/A TRTYR2 Y N/A TRTCD3 Y N/A TRTYR3 Y N/A PRESNFCD N SAME BALIVE N SAME FLDAGE Y N/A ALSTK Y N/A GSSTK Y N/A FORTYPCDCALC Y N/A HABTYPCD1 Y N/A HABTYPCD1_PUB_CD Y N/A HABTYPCD1_DESCR_PUB_CD Y N/A HABTYPCD2 Y N/A HABTYPCD2_PUB_CD Y N/A HABTYPCD2_DESCR_PUB_CD Y N/A MIXEDCONFCD Y N/A VOL_LOC_GRP Y N/A SITECLCDEST Y N/A SITETREE_TREE Y N/A SITECL_METHOD Y N/A CARBON_DOWN_DEAD N CARB_DWN_D CARBON_LITTER N CARB_LIT CARBON_SOIL_ORG N CARB_SOIL CARBON_STANDING_DEAD N CARB_STA_D CARBON_UNDERSTORY_AG N CARB_US_AG CARBON_UNDERSTORY_BG N CARB_US_BG CREATED_BY Y N/A CREATED_DATE Y N/A CREATED_IN_INSTANCE Y N/A MODIFIED_BY Y N/A MODIFIED_DATE N MODIFIED_D MODIFIED_IN_INSTANCE Y N/A CYCLE Y N/A SUBCYCLE Y N/A SOIL_ROOTING_DEPTH_PNW Y N/A GROUND_LAND_CLASS_PNW Y N/A PLANT_STOCKABILITY_FACTOR_PNW Y N/A STND_COND_CD_PNWRS Y N/A STND_STRUC_CD_PNWRS Y N/A STUMP_CD_PNWRS Y N/A FIRE_SRS Y N/A GRAZING_SRS Y N/A HARVEST_TYPE1_SRS Y N/A HARVEST_TYPE2_SRS Y N/A HARVEST_TYPE3_SRS Y N/A LAND_USE_SRS Y N/A OPERABILITY_SRS Y N/A STAND_STRUCTURE_SRS Y N/A --------------------------------------------------------------------------------------------- (7) Dropped all fields in the FL_POP_STRATUM.CSV table with the exception of the EXPNS field (8) Dropped 88 records from the coverage.

The CNTY_PLT item is therefore a unique identifier for each plot, and can be used in place of the PLT_CN item. (10) Added NO_TREES field representing on the number of trees over one inch in diameter on each plot. Field derived from the FL_TREES.CSV table in the FIA database. A frequency function was performed on the table with PLT_CN being the case field. This returned the number of recorded trees on each plot. (11) Added the DESCRIPT item based on FORTYCD item. (12) Added item FGDLAQDATE based on the date GeoPlan acquired the data. Process Date: 20090710 |
