Includes the following data sets from Kenneth Creek installation litterfall collection:

Traps were emptied 3 times per year (May, August, October) and the weights of the sorted contents of each trap were reported for each collection interval in these files:

• BOWAUG95.XLS
• BOWOCT95.XLS
• BOWMAY96.XLS
• BOWAUG96.XLS
• BOWOCT96.XLS
• BOWMAY97.XLS
• BOWAUG97.XLS
• BOWOCT97.XLS
• BOWMAY98.XLS

• BOWOCT98.XLS
• BOWMAY99.XLS

Sorted litter trap materials – composited for each plot and sampling date – were submitted annually to the Ministry of Forests and Range Analytical Chemistry Laboratory for analysis. The following files provide the link between the sequential sample numbers used in the lab result reports and the records of sampling date, plot number, and material type:

• BOW95LIS.xls
• BOW96LIS.xls
• BOW97LIS.xls
• BOW98LIS.XLS
• BOW99LIS.XLS

The following files have the original lab reports in the “Raw Data” pane, and the lab data merged with the sample identification information in the “Labelled” pane:

• T368finl (May -Oct 1995).xls [August & October 1995 litter collections]
• T384finl (Oct 1995-May 1996).xls [May 1996 litter collection]
• T424finl (May-Oct 1996).xls [August & October 1996 litter collections]
• T442finl (Oct 1996-May 1997).xls [May 1997 litter collection; sample numbers shown in red indicate small samples, so micronutrient data may have lower accuracy]
• T458finl (May-Aug 1997.xls [August 1997 litter collection; samples #1-6 are the initial pine needle litter materials used in the companion litterbag decomposition experiment, with #1-3 = Control, #4-6 = ON2]
• T463finl (Aug-Oct 1997).xls [October 1997 litter collection]
• T488FINL (Oct 1997-May 1998).xls [May 1998 litter collection]
• T518finl (May-Aug 1998).xls [August 1998 litter collection]
• T530finl (Aug-Oct 1998).xls [October 1998 litter collection]
• T568FINL (Oct 1998-May 1999).xls [May 1999 litter collection]

Four files have annual summaries of litterfall amounts, element concentrations, and element fluxes by plot and treatment:

• Litterfall Summary 1995-96.xls
• Litterfall Summary 1996-97.xls
• Litterfall Summary 1997-98.xls
• Litterfall Summary 1998-99.xls

More compact tabular summaries of the litterfall and element fluxes over the 4-year period of monitoring are in:

• Litterfall Annual Flux Summary.xls
• Litterfall Annual Fluxes 1995-99 (Tables).xls

Three additional files provide pine foliar chemical data and preliminary estimates of the extent of element retranslocation from foliage prior to litterfall:

• Kenneth Creek (EP886.13) foliar data (1993-99) .xlsx
• Kenneth Creek nutrient retranslocation.xls
• Autumn foliage & needle litter comparison.xls

This document describes the background, objectives and experimental design of Ministry of Forests EP 886.13; research sites are not identified.

During a year away from studies in 1987-88, Dr. Paul Sanborn developed a successful grant proposal to the Science Council of BC (SCBC) to pursue a postdoctoral project with Dr. Tim Ballard in relation to sulphur-deficient soils in BC and prescribed fire. This project built on an existing broadcast burning study conducted by Macmillan Bloedel Ltd. near Port Alberni on Vancouver Island, led by Bill Beese (later at Vancouver Island University). Dr. Sanborn's work addressed sulphur forms and amounts in the soils at these sites, and the chemical processes influencing sulphur availability in relation to prescribed fire.

Only one part of this work was eventually published:
Sanborn, P.T. and T.M. Ballard. 1991. Combustion losses of sulphur from conifer foliage: Implications of chemical form and soil nitrogen status. Biogeochemistry 12: 129–134. https://doi.org/10.1007/BF00001810

The remainder of the work was documented in this Project Completion Report to SCBC, dated February 28, 1990, and entitled "Effects of Prescribed Fire on Sulphur in Forest Soils".

Thirty-four data files were selected for archival retention. There is some redundancy of content among these, with some formatted for incorporation as tables in the report appendices, and others containing some of the same data, but set up as input files for a statistics program. These account for almost all of the data listed in the Project Completion Report appendices. No glossary of variable names is provided, but these should be identifiable by referring to the Report.

Unpublished results for the Sulphur stable isotope tracer study (E.P. 886.15) were presented in annual reports to the funding agencies, including this FRBC 2001 Preliminary Final Report from April 2002.

Unpublished results for the Sulphur stable isotope tracer study (E.P. 886.15) were presented in annual reports to the funding agencies, including this FII Final Report from April 2003.

Document is a research installation layout map for the Kenneth Creek site of the Sulphur stable isotope tracer study (E.P. 886.15).

Data set consists of lab data for sites Y04-01 to Y04-04. Original data set created in 2004; an update was provided in March 2023 but horizon designations were not updated to be consistent with the paper.
