BOREAS TE-6 NPP for the Tower Flux, Carbon Evaluation, and

Auxiliary Sites

Stith T. Gower, Jason G Vogel

Summary

The BOREAS TE-6 team collected several data sets to examine the influence of vegetation, climate,

and their interactions on the major carbon fluxes for boreal forest species. This data set contains

estimates of the biomass produced by the plant species at the TF, CEV, and AUX sites in the SSA and

NSA for a given year. Temporally, the data cover the years of 1985 to 1995. The plant biomass

production (i.e., aboveground, belowground, understory, litterfall), spatial coverage, and temporal

nature of measurements varied between the TF, CEV, and AUX sites as deemed necessary by

BOREAS principal investigators. The data are stored in tabular ASCII files.

1. Data Set Overview

1.1 Data Set Identification

BOREAS TE-06 NPP for the Tower Flux, Carbon Evaluation, and Auxiliary Sites

1.2 Data Set Introduction

The data provided are estimates of the accumulation of biomass by the plant species for a given

ear, or net primary productivity (NPP), at the BOReal Ecosystem-Atmosphere Study (BOREAS)

orthem Study Area (NSA) and Southern Study Area (SSA)Tower Flux (TF), Carbon Evaluation

(CEV), and Auxiliary (AUX) sites. Estimates for the aboveground and belowground biomass

increment and detritus production and the understory biomass increment are found to varying degrees

within these data sets for all sites.

These NPP data sets are part of the effort by the Terrestrial Ecology (TE)-06 team to develop

carbon budgets for the various Canadian boreal forest types. NPP is both the result of and the

precursor to a number of important dynamics within the boreal forest that determine whether this forest

type is a sink or source of carbon dioxide in climate change scenarios.

1.3 Objective/Purpose

The objective of this study was to quantify the NPP for the TF, CEV, and AUX sites.

1.4 Summary of Parameters

Aboveground NPP(ANPP) stem increment, foliage increment, understory increment, litterfall, root

NPP, overstory biomass increment.

1.5 Discussion

NPP is an estimate of the incremental production of biomass by plants in an ecosystem. Generally,

NPP is the sum of overstory biomass increment, aboveground litterfall, and belowground detritus

production. The data sets collected are part of the TE-06 team's effort to quantify the plant carbon

sequestration as expressed by the production of biomass in a given year.

Diameter measurements were made for variable radius and fixed area plots at each site. Stem

increment data and allometric equations were then used to quantify biomass for a given year, and the

difference between years was considered ANPP. Litterfall was measured at the TF sites and the CEV

sites with litter screens.

NPP estimates for the TF and CEV sites are of good quality because they were derived from

site-specific allometric equations and direct measurements of litterfali. Foliage and litterfali estimates

derived for the AUX sites may suffer from not being site specific allometric equations. From a spatial

perspective, the TF site plots were located in areas that approximated the ANPP of the forest within the

Wind-Aligned Blob (WAB), while the CEV and AUX plots were located to describe the ANPP within

a 30- x 30-m area.

3. Theory of Measurements

The accumulation of biomass, or NPP, is the net result of photosynthesis by a plant after plant

respiration. These measurements were made to best quantify ANPP for the years 1993 and 1994 for

the TF and CEV sites and 1994 and 1995 for the AUX sites. Historical overstory biomass increment

estimates are provided, although accuracy becomes an increasing problem where historical data are

concerned because of plot sampling methodology and allometric equation limitations.

5. Data Acquisition Methods

Understory and overstory increment, fine root NPP, and litterfall estimates were made for the

overstory and understory at the Old Black Spruce (OBS) (Picea mariana), Old Jack Pine (OJP) (Pinus

banksiana), and Old Aspen (OA) (Populus tremuloides) TF sites. At the CEV sites, the understory and

overstory increment and litterfall were measured. Only the overstory increment was measured at the

AUX sites.

In the field, plots were established using either a 10 BAF prism or a measuring tape. The diameters

of trees located within a plot were measured, and either a disk or a core was removed at the exact place

a diameter measurement was made. In the lab, the distance between the tree rings was measured to the

nearest 0.001 mm. The diameter for successive years was then calculated, and allometric equations

were used to determine the biomass for that year. The difference in biomass was considered the

overstory ANPP.

The other component of ANPP, litterfall, was measured at the TF and CEV sites by placing 40

60-m x 40-cm or 5 l-m x l-m screens in the plots. The difference in the number of screens placed at

the TF vs. CEV sites was a function of the area that we were attempting to describe the litterfall amount

for; the 500-m WAB at the TF sites and a 30-m x 30-m area at the CEV sites. For two CEV sites,

D9G4A and D9I IM, titterfall was estimated from the new foliage allometric equation developed for

D911 M, and therefore there are only estimates for the aspen foliage. The litter screen size used

depended on the tree density; for greater density, smaller screens were used. The screens were

collected in the fall and spring to determine 1 year of iitterfall. The litterfali was separated by species

foliage and the nonfoliage component.

Understory vegetation was sampled from a 2-m x 2-m or 1-m x 1-m subplot that was randomly

located in each of the plots. The subplot size varied depending on plant density. All vegetation in the

plot was clipped and stored in a cold room (3 °C) until it was processed. Samples were separated into

7.1 Spatial Characteristics

7.1.1 Spatial Coverage

At the TF sites, four replicate plots were established immediately outside the footprint of the tower.

The plots were located in areas that reasonably represented the vegetation within the WAB and should

provide accurate stand level descriptions. The plot size varied from 7.5 x 7.5 m to 30 x 30 m

depending upon tree density. The number of trees per plot ranged from 60 to 120. The CEV and AUX

sites were sampled to describe the biomass within a 30- x 30-m area. The North American Datum of

1983 (NAD83) coordinates of the sites are:

8. Data Organization

8.1 Data Granularity

The smallest unit of data tracked by the BOREAS Information System (BORIS) was the data

collected at a given site on a given date.

8.2 Data Format(s)

The Compact Disk-Read-Only Memory (CD-ROM) files contain American Standard Code for

Information Interchange (ASCII) numerical and character fields of varying length separated by

commas. The character fields are enclosed with single apostrophe marks. There are no spaces between

the fields.

Each data file on the CD-ROM has four header lines of Hyper-Text Markup Language (HTML)

code at the top. When viewed with a Web browser, this code displays header information (data set

title, location, date, acknowledgments, etc.) and a series of HTML links to associated data files and

related data sets. Line 5 of each data file is a list of the column names, and line 6 and following lines

contain the actual data.

9. Data Manipulations

9.1 Formulae

9.1.1 Derivation Techniques and Algorithms

Tree biomass is calculated from a diameter measurement and an allometric equation and then scaled

to the hectare level using a p]ot scaling factor that reflects the tree's representative size in relation to the

plot size (Dilworth and Bell, 1979). Allometric equations are generally developed on a log-log basis to

correct for nonhomogeneous variance (see BOREAS TE-06 Allometry Data documentation).

Biomass by component

(Kg/HA) = (INVLOG(a + b (LOG (diameter)))) * PLOT SCALING FACTOR

Tree increment (multiplied by 2 and corrected for a tree bark thickness of 0.1 cm) is then subtracted

from or added to the original diameter measurement (depending on when the tree diameter was

measured and tree core taken) to develop an estimate of another year's diameter.

1993 diameter = 1994 measured diameter - 1993 measured increment

Biomass is then calculated for two consecutive years, and the difference between the two is considered

the overstory increment.

Overstory Increment = 1994 Biomass by component - 1993 Biomass by component

For determining litterfall mass by component at the tower sites, screens are averaged by plot and scaled

to the hectare level. The stand average is then determined and added to the overstory biomass

increment.

9.2 Data Processing Sequence

9.2.1 Processing Steps

None given.

9.3 Calculations

9.3.1 Special Corrections/Adjustments

Not applicable.

9.3.2 Calculated Variables

See Section 9.1.1.

9.4 Graphs and Plots

Not applicable.

10. Errors

10.1 Sources of Error

The greatest potential source of error other researchers need to be aware of for the TF sites is not

from the data collection or calculation but from differences in vegetation between where other

researchers may have worked and where the TE-06 team located its plots. Researchers should contact

Tom Gower if they feel plot location may be affecting any corroboration between their estimates and

these. The variability for fine root production is high for these estimates, as is the case for most

estimates of fine root production. It is likely that this variation is a reflection of the variability within

boreal forests. The estimates for overstory root increment are based on generalized equations and are

not all species specific, but problems surrounding this usage are likely minimal (Santantonio et al.,

1977)

For the AUX sites, difficulty surrounding the efficacy of non-site-specific allometric equations in

estimating biomass and overstory biomass increment values occurs at a number of sites. Estimating

overstory biomass increment from non-site-specific equations for wood and branch increment is

problematic when the diameters of the trees measured are smaller or larger than the diameters of the

trees that were harvested to develop the allometric equation. For this reason, the biomass for trees at

the AUX and CEV sites that had a diameter that was either too large or small for the TF allometric

equations was estimated from the Singh (1982) equations.

10.2 Quality Assessment

The data provided are of generally good quality with the above considerations taken into account.

10.2.1 Data Validation by Source

It is not possible to validate the data without developing new allometric equations and/or installing

new plots. A check was performed using published allometric equations (Singh, 1982) and there was

generally good agreement for total biomass increment at all sites, but poor agreement for foliage

increment, which is not unexpected.

10.2.2 Confidence Level/Accuracy Judgment

Confidence level for the TF sites is high for the data submitted and slightly less so for some AUX

sites. Researchers should note Section 10.1.

10.2.3 Measurement Error for Parameters

Not applicable.

10.2.4 Additional Quality Assessments

Not applicable.

Page 17
10.2.5 Data Verification by Data Center

Data were examined for general consistency and clarity.

1 1. Notes

11.1 Limitations of the Data

The CEV and AUX increment estimates are limited to a 30- x 30-m area surrounding a point

located using a Global Positioning System (GPS). The location of these points can be found in the

STAFF directory of BORIS.

11.2 Known Problems with the Data

The overstory increment numbers provided for 1985-92 and 1986-93 at the TF/CEV and AUX

sites likely decrease in accuracy as one projects back in time (see Section 10.1).

11.3 Usage Guidance

None.

11.4 Other Relevant Information

None.

12. Application of the Data Set

NPP is both the result of and the precursor to a number of important dynamics within the boreal forest

that may determine whether this forest type is a sink or source of carbon dioxide in future climate

change scenarios. The estimates provided by this effort also provide a means of validation for models

that develop carbon budgets for these forests.

13. Future Modifications and Plans

Estimates for the 1996 overstory increment and litterfall data may be available; please contact the

investigator (see Section 2.1).

13. ABSTRACT (Maximum 200 words)

The BOREAS TE-6 team collected several data sets to examine the influence of vegetation, climate,

and their interactions on the major carbon fluxes for boreal forest species. This data set contains

estimates of the biomass produced by the plant species at the TF, CEV, and AUX sites in the SSA and

NSA for a given year. Temporally, the data cover the years of 1985 to 1995. The plant biomass production (i.e., aboveground, belowground, understory, litterfail), spatial coverage, and temporal nature

of measurements varied between the TF, CEV, and AUX sites as deemed necessary by BOREAS

principal investigators. The data are stored in tabular ASCII files.

14.SUBJECTTERMS

BOREAS, terrestrial ecology, plant biomass.
