GENERAL DESCRIPTION:
This dataset contains information from the Forest Inventory and Analysis (FIA) Program conducted by the U.S. Department of Agriculture Forest Service. FIA is a continuing endeavor mandated by Congress in the Forest and Rangeland Renewable Resources Planning Act of 1974 and the McSweeney-McNary Forest Research Act of 1928. FIA's primary objective is to determine the extent, condition, volume, growth, and depletions of timber on the Nation's forest land. Points within the dataset represent approximate coordinates for every plot location in the database in the State of Florida. Due to privacy rights the coordinates have been adjusted and are generally within one mile of the actual location. FIA reports on status and trends in forest area and location; in the species, size, and health of trees; in total tree growth, mortality, and removals by harvest; in wood production and utilization rates by various products; and in forest land ownership.

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.
1 = Northeastern

2 = Northwestern

3 = Central

4 = Southern


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.
1 = Sampled - at least one accessible forest land condition present on plot

2 = Sampled - no accessible forest land condition present on plot

3 = Nonsampled


NO_SAMP_CD Plot nonsampled reason code. For entire plots that cannot be sampled, one of the following reasons is recorded.
01 = Outside U.S. boundary - Entire plot is outside of the U.S. border.

02 = Denied access area - Access to the entire plot is denied by the legal owner, or by the owner of the only reasonable route to the plot.

03 = Hazardous - Entire plot cannot be accessed because of a hazard or danger, for example cliffs, quarries, strip mines, illegal substance plantations, high water, etc.

05 = Lost data - Plot data file was discovered to be corrupt after a panel was completed and submitted for processing.

06 = Lost plot - Entire plot cannot be found.

07 = Wrong location - Previous plot can be found, but its placement is beyond the tolerance limits for plot location.

08 = Skipped visit - Entire plot skipped. Used for plots that are not completed prior to the time a panel is finished and submitted for processing. This code is for office use only.

09 = Dropped intensified plot - Intensified plot dropped due to a change in grid density. This code used only by units engaged in intensification. This code is for office use only.

10 = Other - Entire plot not sampled due to a reason other than one of the specific reasons already listed

11 = Ocean - Plot falls in ocean water below mean high tide line.


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.
1 = 100 ft or less

2 = 101 ft to 300 ft

3 = 301 ft to 500 ft

4 = 501 ft to 1000 ft

5 = 1001 ft to 1/2 mile

6 = 1/2 to 1 mile

7 = 1 to 3 miles

8 = 3 to 5 miles

9 = Greater than 5 miles


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.
0 = None - no water sources within the accessible forest land condition class

1 = Permanent streams or ponds too small to qualify as noncensus water

2 = Permanent water in the form of deep swamps, bogs, marshes without standing trees present and less than 1.0 ac in size, or with standing trees

3 = Ditch/canal - human made channels used as a means of moving water, e.g., for irrigation or drainage, which are too small to qualify as noncensus water

4 = Temporary streams

5 = Flood zones - evidence of flooding when bodies of water exceed their natural banks

9 = Other temporary water - specified in plot-level notes.


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.
0 = Not Reserved

1 = Reserved


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).
11 = National Forest System

12 = National Grassland

13 = Other Forest Service

21 = National Park Service

22 = Bureau of Land Management

23 = Fish and Wildlife Service

24 = Department of Defense/Energy

25 = Other federal

31 = State

32 = Local (County, Municipal, etc)

33 = Other non-federal public

46 = Undifferentiated private


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).
1 = Large diameter: Stands with an all live stocking of at least 10 (base 100); with more than 50 percent of the stocking in medium and large diameter trees; and with the stocking of large diameter trees equal to or greater than the stocking of medium diameter trees

2 = Medium diameter: Stands with an all live stocking of at least 10 (base 100); with more than 50 percent of the stocking in medium and large diameter trees; and with the stocking of large diameter trees less than the stocking of medium diameter trees

3 = Small diameter: Stands with an all live stocking value of at least 10 (base 100) on which at least 50 percent of the stocking is in small diameter trees

5 = Forest land with all live stocking less than 10


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.
1 = 225+ cubic feet/acre/year

2 = 165-224 cubic feet/acre/year

3 = 120-164 cubic feet/acre/year

4 = 85-119 cubic feet/acre/year

5 = 50-84 cubic feet/acre/year

6 = 20-49 cubic feet/acre/year

7 = 0-19 cubic feet/acre/year


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
0 = Natural stands

1 = Clear evidence of artificial regeneration


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.
107 = Sand Pine

110 = Shortleaf Pine

111 = Slash Pine

121 = Longleaf Pine

131 = Loblolly Pine

132 = Virginia Pine

510 = Eucalyptus spp

513 = Grand Eucalyptus

611 = Sweetgum


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.

BALIVE Basal area of live trees. Basal area in square feet per acre of all live trees over 1 inch DBH/DRC sampled in the condition.

CARB_DWN_D Carbon in down dead. Carbon in woody material on the ground larger than 3 inches in diameter as well as stumps and their roots greater than 3 inches. Calculated carbon density (tons per acre) based on region, forest type and live tree carbon density (Smith and Heath 2008)

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_SOIL Carbon in organic soil. Carbon in fine organic material below the soil surface to a depth of 1 meter. Does not include roots. Calculated carbon density (tons per acre) based on region and forest type (Smith and Heath 2008).

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.

CARB_US_AG Carbon in understory aboveground. Carbon in the aboveground portions of seedlings, shrubs, and bushes. Calculated carbon density (tons per acre) based on region, forest type and live tree carbon density (Smith and Health 2008).

CARB_US_BG Carbon in understory belowground. Carbon in the belowground portions of seedlings, shrubs, and bushes. Calculated carbon density (tons per acre) based on region, forest type and live tree carbon density (Smith and Heath 2008).

NO_TREES The number of trees one inch in diameter and larger on the plot.

MODIFIED_D Modified date. The date the record was last modified. This field will be blank (null) if the data have not been modified since initial creation. Date will be in the form DD-MON-YYYY

DESCRIPT Based on FORTYPCD item.

FGDLAQDATE The date FGDL aquired the data

USER NOTES:
See "Attribute_Accuracy_Report". 
Many of the checks described in that section check for both attribute 
accuracy and logical consistency.
Plot locations with missing lat/long coordinates were excluded 
from the dataset.
GeoPlan relied on the integrity of the attribute information within
the original 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.

A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data. 

1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding

DATA LINEAGE SUMMARY:
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;

(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. These records had no Latitude or Longitude
data and therefore could not be generated as accurate points. 
(9) Added item CNTY_PLT based on the FIPS county code and the plot number for 
each plot. The purpose of this was to get around the fact that plot numbers repeated 
in different couties. 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.
