NPP Multi-Biome: Global IBP Woodlands Data, 1955-1975, R1
Get Data
Revision date: September 13, 2013

Summary:

This data set provides four data files containing net primary productivity (NPP) data, edaphic characteristics, average climatic conditions, and basic descriptive and quantitative information on vegetation for 117 globally-distributed terrestrial forest sites. The data set was derived from the IBP (International Biological Programme) Woodlands Data Set of DeAngelis et al. (1981). The data were collected from the mid 1950s to the early 1970s and were compiled into an electronic data set at the Oak Ridge National Laboratory to facilitate comparisons involving the diverse woodland ecosystems.

One data file provides a complete synthesis of NPP, vegetation, edaphic, and climate data and data-source references for each of the 117 sites as published in DeAngelis et al. (1981) for a total of 5,887 records. The second file provides site location, biome, and selected forest productivity and soils data for the 117 sites. The third file provides summary climate data (temperature, precipitation, radiation, growing season length) for each site, and the fourth file provides forest type, investigator(s), and years of the study for each site.

Revision Notes: Only the documentation for this data set has been modified. The data files have been checked for accuracy and are identical to those originally archived in 1997 (DeAngelis, et al, 1997.)

Additional Documentation:

The Net Primary Productivity (NPP) data collection contains field measurements of biomass, estimated NPP, and climate data for terrestrial grassland, tropical forest, boreal forest, and tundra sites worldwide. Data were compiled from the published literature for intensively studied and well-documented individual field sites and from a number of previously compiled multi-site, multi-biome data sets of georeferenced NPP estimates. The principal compilation effort (Olson et al., 2001) was sponsored by the NASA Terrestrial Ecology Program.

1. Data Set Overview:

Project: Net Primary Productivity (NPP)

The IBP (International Biological Programme) Woodlands Data Set contains contributions from 117 international forest research sites, all but a few associated with projects committed to the IBP. The field measurements data were collected from the mid-1950s to the mid-1970s. The data were compiled into a single data set at the Oak Ridge National Laboratory (ORNL) to facilitate comparisons involving the diverse woodland ecosystems. The data set was originally published in DeAngelis et al. (1981) and was extracted from that reference to be presented here.

Site Information

Almost every kind of forest ecosystem is represented in the data set (Burgess, 1981). A hierarchical scheme was used to assign a forest type to each site based on the climate, life-form, behavior, and status features of the site. Included are sites of the following types, with the number of each forest type in parentheses: Tropical (26), Mediterranean (3), Temperate (55), and Boreal (33). With respect to life-form, 72 sites were dominated by broad-leaved species and 45 were needle-leaved. There were 65 deciduous stands and 52 evergreen. Finally, 89 sites consisted of natural forest and 28 were managed. Overall, the sites were classified by biome, as shown in Table 2. There is a reasonable representation of all terrestrial forest categories with the exception of Mediterranean woodlands, which are under-represented.

NPP Data. The IBP Woodlands Data Set provides data for 117 globally distributed forest sites. The data were extracted from DeAngelis et al. (1981) and organized into four files, as described in Table 3. The variable values are delimited by semicolons. The first 16 lines in each file are metadata; data records begin on line 17. All NPP units are in g/m2 (dry matter weight). Other units of measure are given in tables below. The values 999.9, -9.9, -9.99, -99.9, -99.90, -999, -9999, and -99999 are used to denote missing values.

The data records in each file are organized in alphabetical order by country. The first file [woodland.txt] provide the complete record for each forest site. This file contains 5,887 records.The data are arranged in a single column with each variable on a separate line. The other three files are arranged as row and column tables. The second file [wdlnd_1.txt] identifies site location, biome, and selected forest productivity and soils data. There is one line per record, for a total of 117 records. The third file [wdlnd_2.txt] provides climate data (temperature, precipitation, radiation, growing season length) organized by site. There is one line per record, for a total of 117 records. The fourth file [wdlnd_3.txt] provides site forest type, investigator(s) name(s), and years of the study, organized by site. There is one line per record, for a total of 117 records.

Abbreviations for data variables are used so that the data can be presented in a compact form. Tables 4-8 below provides definitions of abbreviations and terms used in conjunction with the data set (adapted from DeAngelis et al., 1981). Tables 9-12 provide definitions of column headings as they are used and organized in the data files. Data format notes are also available. References are provided for the source of the data and compilation process.

Several symbols are used in the biomass compartment tabulations:

Table 4. Definitions for interpreting data in the data set

TERM DEFINITION
Basal Area IncrementThe amount of woody tissue added to the stand basal area per year through growth
CompartmentA division of the ecosystem for which we may measure organic matter in terms of dry weight
Increment (Net annual)The change in the size of a compartment during a year. For example, leaf mass in July 1970=812 g/m2 and leaf mass in July 1971=826 g/m2. The increment is therefore 14 g/m2/yr. Note that increment in this example does not include leaf litterfall. Similar definitions are used for branch and bole increments, with branch and bole litterfall not included in the increment.
Field LayerHerbaceous plants, mosses and lichens. Woody plants less than 50 cm in height are included here.
Flux (Net annual) The annual amount of organic matter being transferred (e.g., by litterfall) from one compartment to another
FrassIncludes insect excreta and may include other unidentifiable materials
Global RadiationThe sum of irradiance on a horizontal surface caused by direct solar radiation and diffuse short-wave radiation due to clouds, dust and molecular scattering from all parts of the sky. (Definition from Van Wijk and Scholte Ubing, 1966).
OverstoryThe trees forming the main canopy
Productivity (Net annual)The sum of litterfall plus all biomass increments plus consumption not accounted for in production
Radiation BalanceThe difference between short-wave radiation from the sky and the sum of short-wave reflected radiation and long-wave terrestrial radiation
Soil Top OrganicIncludes recently fallen litter (L layer) as well as decomposing organic layers on top of the mineral soil (F and H layers)
Standing DeadDead plants or parts of plants still standing in the forest
Stocking DensityNumber of stems per hectare
Understory (or Substory) The sum of sub-canopy and shrub layers

3. Data Application and Derivation:

The Woodlands Data Set provides a unique historical resource for the analysis of forest ecosystems. Previous to this compilation, attempts to compare the forests of the world were limited by the small number of research sites which had been documented with methods and parameters similar enough to permit comparison. O'Neill and DeAngelis (1981) compared the Woodlands Data Set with other analyses of general patterns in world forests that had appeared in the literature. Among the analyses compared were the proposed relationship between productivity and climatic variables, the quantity of leaf and total litterfall by type and region, and the ratio of wood production to leaf litter production as a function of growing season global radiation. O'Neill and DeAngelis (1981) also analyzed the Woodlands Data Set to determine forest characteristics that were relatively independent of site and species differences. Although the differences among the research sites are quite large, some patterns were consistent across all forests, such as stand height as a function of total above-ground biomass and the relationship between diameter classes and the density of trees. Other characteristics hold true for major forest types, such as evergreen and deciduous, or gymnosperms and angiosperms. An example of the latter is biomass of various plant components as a function of total above-ground biomass.

 

4. Quality Assessment:

The projects submitting data to the Woodlands Data Set were diverse, both internationally and in the scope and emphasis of their research. Because of this, the data did not always conform easily to the uniform format in which it is presented here. According to the compilers (DeAngelis et al., 1981), "Repeated communications with members of various projects were often employed before deciding on appropriate values. We have tried to follow faithfully the wishes of the projects in this regard."

Some data quality caveats are as follows:

Rigorous comparisons among sites are complicated because of the above data constraints and because for each site there many be additional highly pertinent facts which could not be included in the data summaries. See O'Neill and DeAngelis (1981) for a discussion of these constraints. Those users of the data wishing to pursue similar analyses may also want to consult the primary literature publications relevant to each site, which are cited in the general site descriptions in DeAngelis et al. (1981) and in [woodland.txt].

5. Data Acquisition Materials and Methods:

The Woodlands Data Set represents the integrated product of collaborating scientists from 23 countries around the world. Implementation of an international woodlands program began with a workshop in 1968 in Tennessee, U.S.A., published as Analysis of Temperate Forest Ecosystems (Reichle, 1970). This was followed by Productivity of Forest Ecosystems of the World (Duvigneaud, 1971), a UNESCO symposium held in 1969 in Brussels, Belgium. In 1971, a workshop in Sweden (Rosswell, 1971) refined conceptual approaches and analytical measurements for forest studies. Three additional workshops were held to facilitate exchange and analysis of the data being produced. The data files of the first workshop in 1972 in Tennessee were published as Modeling Forest Ecosystems (Reichle et al., 1972). From the next workshop in 1974 in Gottingen, Germany, an updated data file was prepared and published as Data Analysis and Data Synthesis of Forest Ecosystems (Ulrich et al., 1974). A common computer format was established and computer storage and analysis of data was undetaken by Oak Ridge National Laboratory (ORNL). In 1975, the last workshop was held in Jadrass, Sweden, to update the data files. The results of this sequence is the Woodlands Data Set, published in DeAngelis et al. (1981).

In DeAngelis et al. (1981), the data for each site were organized into three general parts. The first part identified the investigator(s), selected citations, years of the study, forest type, soil and geology types, and principal plant types. The second part consisted of general site description data, including edaphic characteristics, average meteorological conditions, and basic descriptive and quantitative data on the vegetation. In the last part, data for up to 38 biomass compartments are presented. Tables present the measured amounts and increments in these compartments, as well as the fluxes between them.

The data in DeAngelis et al. (1981) were extracted and reorganized in digital format and archived in 1997 by ORNL DAAC. The latitude and longitude coordinates were converted to decimal degrees and a biome type from Burgess (1981) was added to each site record.
