    February 25, 1993

    The datafile on the attached disk is the Global Forest Practices Database that was assembled in 1991 at the EPA Environmental Research Laboratory, Corvallis, OR, USA. All data is in ascii file format. Variables are delimited with a "~" (tilde) character (1841 observation, 36 variables).

    Below are the field numbers, field descriptions, and maximum field lengths (given in parenthesis) for the Global Forest Practices Database.

    FIELD # DESCRIPTION

    1 3-character World Resources Institute nation code (3).
        See FIELD 2.
    2 Full name of nation (30).
        CODE - NATION NAME _
        ARG - Argentina
        CHN - China
        MYS - Malaysia
        etc.
    3 4-character Bailey ecoregion code (4). See FIELD 4.
    4 Full name of Bailey ecoregion (33)
        CODE - ECOREGION NAME _
        L100 - Boreal lowland
        L200 - Humid temperate lowland
        L300 - Dry tropical and temperate lowland
        L400 - Humid tropical lowland
        M100 - Boreal upland
        M200 - Humid temperate upland
        M300 - Dry tropical and temperate upland
        M400 - Humid tropical upland
    5 2-digit forest practice code (2). See FIELD 6.
    6 Full name of forest practice (40)
        CODE - FOREST PRACTICE NAME _
        10 - Reforestation
        20 - Afforestation
        30 - Forest reserve
        40 - Natural regeneration
        60 - Silviculture
        70 - Short rotation
        80 - Agroforestry
    7 Short note on forest practice. For example, an agroforestry practice may have a short note here describing a specific type of agroforestry such as "Hedgerow Intercropping" (20).
    8 4-character tree species code. Generally, the first two letters from the genus and the first two letters of the species make up the 4-character code (4).
    9 Wood density of tree species based on dry weight per unit of fresh volume of wood. Note that some species may have different densities depending on region, etc... (10)
    10 Rotation length in years, minimum (10)
    11 Rotation length in years, maximum (10)
    12 Rotation length reference number (10).
    13 Trees/hectare (10)
    14 Trees/hectare reference number (10)
    15 Optimistic land available in 10 hectares for practice (20). See FIELD 16.
    16 Pessimistic land available in 10 hectares for practice (20). The words optimistic and pessimistic reflect qualitative assumptions about the amount of resources and level of effort that could be expended on reforestation / regeneration. Assumptions are based on current condition of vegetation (from satellite imagery), predisturbance vegetation (from Matthews [1983] global vegetation map), and allowance for social and economical constraints. For each nation, mixes of optimistic and pessimistic practices were defined by Houghton et al. 1991.
    17 Optimistic and/or pessimistic land availability reference number (10)
    18 1-character site quality classification (1)
        H - High, M - Medium, L - Low.
        F - Forested, W - Woodland, G - Grassland.
        The F,W,G classifications were used as ecoregion place- holders, i.e., F equates with the Bailey ecoregion L400 - Humid tropical lowland, W and G equate with Bailey ecoregion L300 - Dry tropical and temperate lowland.
    19 Site quality reference number (10).
    20 Period of growth response. Often given as a range in months (20).
    21 Period of growth response reference number (10).
    22 Observed growth rate minimum in m/hectare/year (20).
    23 Observed growth rate maximum in m/hectare/year (20).
    24 Observed growth rate reference number (10).
    25 Observed tree biomass growth increment in tons/hectare (20).
    26 Observed tree biomass growth increment reference number (10).
    27 Cost in US dollars to initiate forest practice, minimum (20). See FIELD 27.
    28 Cost in US dollars to initiate forest practice, maximum. Based on the year this data was collected, i.e., the costs have not been adjusted to present value (20).
    29 Cost in US dollars reference number (10).
    30 Annual cost in US dollars to sustain forest practice on a yearly bases, minimum (20). See FIELD 30.
    31 Annual cost in US dollars to sustain forest practice on a yearly bases, maximum. Based on the year this data was collected, i.e., the costs have not been adjusted to present value (20).
    32 Annual cost in US dollars reference number (10).
    33 Year that costing data was collected (4).
    34 Costing multiplier used to adjust costing data from the FIELD 32 US dollars to 1990 US dollars (10). The currency exchange rate for the reference year was taken from the International Financial Statistics Tables (IFS) published by the International Monetary Fund (IMF 1990, 1991). Using the nation's own inflation rate (measured by the Consumer Price Index) the reference cost data was adjusted to its own 1990 net value. This "current" cost data was then converted back to 1990 US dollars at the 1990 exchange rate.
    35 End products, such as fuelwood, lumber, poles, etc... (250).
    36 General comments (250).

    DATA INTEGRATION REPORT

    Overview

    The tabular attribute information was originally in a text file composed of 1840 lines with 36 fields with each field separated by a tilde ('~') character. Additionally, each field was padded with one leading and trailing space character, except the last field, which was padded only with one leading space character.

    Each of the 36 fields is described in DSWVAR.TXT (ASCII text), DSWVAR.WP5 (WordPerfect 5.0 format), and in the series of PCX files DSWVAR_1.PCX through DSWVAR_4.PCX, however, the maximum field lengths given are not always accurate.

    The entries in the database for field 8 (4-character tree species code) are explained in DSWSPEC.TXT (ASCII text), DSWPEC.WP5 (WordPerfect 5.0 format) and in the series of PCX files DSWSPEC1.PCX through DSWSPEC5.PCX. Furthermore, a number of fields in the database (i.e., fields 12, 14, 17, 19 ,21, 24, 26, 29, and 32) are bibliographic reference numbers which are given in DSWREF.TXT (ASCII text), DSWREF.WP5 (WordPerfect 5.0 format) and in the series of PCX files DSWREF01.PCX through DSWREF44.PCX.

    The database file was imported into Microsoft Excel version 4.0 and then exported as a dBase III database file (DSWFOR.DBF). The database was quality checked and fields were converted from text to numeric format whenever possible.

    Note that there is not a one-to-one relationship between geographic areas and attribute values. For example, there are three records in the database for humid temperate lowlands in Argentina with a reforestation practice on tree species AAAN (Araucaria angustifolia) with 6500, 2500, and 600 trees per hectare, respectively, and an observed growth rate minimum and maximum of 24.5, 14.5 and 8 m^3/hectare/year, respectively. All other fields for these three records are identical. For this reason the database has been left as is so that each end-user must impose his or her own criteria on the database before any sort of chlorepleth maps can be produced.

    Importing the Database into Excel

    The file was imported into Excel using the File Open command, specifying a text file with a custom column delimiter '~' (tilde). Leading and trailing spaces were trimmed for all spreadsheet cells. The normal style was changed to a courier font with 10 point spacing. Every column width was adjusted to its best fit so that no column would truncate any entry nor would any column be padded with extraneous spaces.

    The type of each field (text or numeric) was determined, as well as the maximum number of digits in the mantissa for each numeric field (zero indicating an integer field). Each numeric field in the Excel spreadsheet was then reformatted so that all entries had the same number of digits in the mantissa, padding to the right with zeros as necessary.

    The next step was to discover if the representation of the database as a spreadsheet in Excel or any of the above manipulations had caused any corruption of the data.

    Exporting as a fixed-field text

    The Excel macro "FLATFILE.XLM" was used to export the spreadsheet to a text file with fixed fields (padded with spaces so that each field retains their respective line positions for all records, as opposed to the tilde-delimited fields of the source text file).

    Character histograms were computed for both the source and exported text file and compared. As expected, there was the loss of tilde characters, and a gain in space, decimal point, and zero characters (many entries in floating point fields were originally expressed as integers). However, there was a loss of four percentage characters and a loss of seven plus sign characters.

    After inspecting the source file it was discovered that four numbers were originally expressed as percentages but when imported into Excel were converted to decimals (e.g., 13% became 0.13), and these entries were flagged -- see text entries in numeric fields, below. The seven plus signs were lost because seven entries in a numeric field were originally preceded with a plus sign. By default, unsigned numbers are taken as positive, so the seven plus signs were left off.

    While this test is not strictly conclusive, it was decided that the Excel spreadsheet was a faithful representation of the original database.

    Text entries in numeric fields

    After each field was determined to be either numeric or text, it remained to flag any text entries that might exist in a numeric field. The following is a list of numeric fields that contained text entries that were subsequently replaced with a flag value.

    Field 9 -- Wood density of tree species based on dry weight per unit of fresh volume of wood. One record contained the entry "0.25 to 0.." This entry was flagged -2 (minus two).

    Fields 12, 14, 17, 24, and 29 -- Bibliographic reference numbers for rotation length, trees per hectare, optimistic and/or pessimistic land availability, observed growth rate, and cost in US dollars, respectively. Multiple records contained the entries "est" "est jl," and "est rd" with varying capitalization's. These entries were flagged -2, -3, and -4, respectively (minus two, three, and four).

    Field 13 -- Trees per hectare. Several records contained the entry "varies." These entries were flagged -2.

    Field 15 -- Optimistic land available in kilo-hectares for practice. Several records contained the entries "20-30% of country" and ">10000" (greater than ten thousand). These entries were flagged -2 and -3, respectively.

    Field 21 -- Period of growth response reference number. One record contained a semi-colon preceding the reference number. This was assumed to be a typographic error and the semicolon was removed.

    Fields 22 and 23 -- Observed growth rate minimum and maximum, respectively, in cubic meters per hectare per year. Both fields contained the entries "23/1," "13%," and "23%." These entries were flagged -2, -3, and -4, respectively.

    Field 25 -- Observed tree biomass growth increment in tons per hectare. This field contained 26 spreadsheet formulas that were not evaluated but were instead exported verbatim (e.g., "+F22*R22*1.6"). After export these formulas became meaningless since the original row and column ordering was lost, e.g., line 514 in the export file contains the formula "+F22*R22*1.6" (referring to the 22nd record), and calculating "+F22*R22*1.6" would mean multiplying full name of forest practice ("F" column) by one-character site quality classification ("R" column) by 1.6. These entries were flagged -2.

    Last, it was generally found that numeric fields would contain both zero values and blank or empty entries. Assuming that zero values should be distinguished from no entry, blank entries were flagged -1 (minus one).

    Export as a Database file

    The last step was assigning field names to each of the columns in the spreadsheet and saving the file in a dBase III format. For the final publication this database was convered to Microsoft Access and also as an ascii text file.
