Definition: This is the fire complex that the site is located in. A unique site number assigned to each plot (values are between 1 and 92). Site 100 has been reassigned to site 42. Sites 21 and 22 were deleted from the study due to permitting problems. Each site is assigned to one of three types: int=intensive (sites with seedling plantings and exclosures), ext=extensive (no experimental plantings or veg monitoring plots), treeline=similar to intensive but without seedling exclosures. Values are listed only for intensive sites, and assigned to moist or dry based on the original factorial design. Values are listed only for intensive sites, and assigned to high or low based on the original factorial design. Ranking of site moisture potential using the moisture key presented in the successional trajectories workbook. Values determined by JJ during field surveys in 2008. Average of TDR probe measurements taken in July 2005 (10 points/site). The TDR probe was inserted into the surface of the mineral soil (probe length is 12 cm). Values are missing for sites with frozen mineral soil or very rocky soils. Average of TDR probe measurements taken in June 2008 by JJ (5 points/site). The TDR probe was inserted at a 45 degree angle into the surface of the mineral soil (probe length is 12 cm). Where the mineral soil was frozen, measurements were made in organic soil. Average of TDR probe measurements taken in late July - early Aug 2011 (3 points/site). Elevation in m, as recorded on the original site assessment sheets, based on GPS readings. Latitude in decimal degrees, as recorded on the original site assessment sheets based on GPS readings (using NAD 83 as datum) Longitude in decimal degrees, as recorded on the original site assessment sheets based on GPS readings (using NAD 83 as datum) Slope in degrees. Original values taken from TNH vegetation plot records, later revised based on new inclinometer measurements made by Jill Johnstone's crew in 2008. Slope aspect in compass degrees (0 to 360), taken from compass readings made in 2008 (corrected for declination). Soil pH, measured from near-surface mineral soil samples (where mineral soils could be sampled), collected in 2005-2006. Analyses done by Palmer lab and Leslie Boby. N=4 to 5 for intensive sites, n=1 for extensive sites Percent sand, based on texture analysis of near-surface mineral soil (Palmer lab). Only one sample per site. Percent silt, based on texture analysis of near-surface mineral soil (Palmer lab). Only one sample per site. Percent clay, based on texture analysis of near-surface mineral soil (Palmer lab). Only one sample per site. Texture classes estimated in the initial site assessment were ranked from coarse to fine (1 to 5) Hillslope position classes, based on the original site assessment (site photos were used to fill in missing data). Classes are in order of decreasing moisture. Date of burning in 2004, based on Modis Hotspot data (from Dave Verbyla). Date of burning in 2004, based on Modis Hotspot data (from Dave Verbyla). These are the same data as previous column, but represented as Julian days. Normalized Burn Ratio, estimated from satellite data (from Dave Verbyla). We used dNBR data from early September 2004 images (TC=9 Sept, DC=3 Sept, BF=6 Sept). This is a rough ranking of surface fire severity, compiled by Jill Johnstone based on the initial site assessment. Numerical index of ranking of surface fire severity, ranking from 1 (low) to 5 (high) Percent tree mortality at the site, from the initial site assessment. Ranking of stand-level tree canopy consumption or canopy severity. Estimated percent of canopy consumption by the fire (tree boles excluded). Leslie Boby dataset. Based on unpublished allometric equations for canopy biomass components that are estimated from basal diameter, and % loss of each biomass category observed per tree in the field. Proportion of standing trees, calculated on the basis of basal area. Data from Leslie Boby. Calculations are for black and white spruce pooled together. Proportion of standing trees, calculated on the basis of the number of tree stems. Data from Leslie Boby. Calculations are for black and white spruce pooled together. Estimated time since last fire, based on the youngest cluster of >2 stems with ages that are within 10 years of each other. Based on 5 basal stem disks sampled per site. Estimated age of the oldest tree, which is may estimate the time since stand-replacement fire. This age may be greater than time since last fire if the last fire left some survivors. An index of the distribution of the pre-fire stand recruitment ages, based on 5 samples. Total CBI score following standard procedures for the Composite Burn Index (data collected by Andi Ruth, July 2005). Data are missing for several plots. Scale is from 0-3, with 3 being highest severity. CBI score for understory component only. Scale is from 0-3, with 3 being highest severity. CBI score for overstory component only. Scale is from 0-3, with 3 being highest severity. CBI score for substrate component only. Scale is from 0-3, with 3 being highest severity. Residual (postfire) organic layer depth (cm), measured at 11 random points per site by Leslie Boby in 2006. Missing data for DC33 and BF92 filled in by Jill Johnstone in 2007. Estimated pre-fire depth of the organic layer (cm), based on post-fire depth, corrected using adventitious root data (Leslie Boby dataset). Estimated fire consumption of the organic layer, based on comparisons of estimated pre-fire depth and measured residual depth (Leslie Boby dataset). Percentage of soil sample points (usually n=22) at a site with organic layer depths of less than 3 cm. Surface cover of bare organics, as a percentage of 60 point-intercept samples/site in 2006 (Jill Johnstone dataset). Surface cover of colonizing mosses (Marchantia, Polytrichum, and Ceratadon-type mosses), as a percentage of 60 point-intercept samples/site in 2006 (Jill Johnstone dataset). Surface cover of dead scorched moss (feathermosses and Sphagnum), as a percentage of 60 point-intercept samples/site in 2006 (Jill Johnstone dataset). Postfire nitrogen pool from the soil organic layer (kg/m2), calculated from remaining organic layer depths, burn site bulk densities, and nitrogen concentrations for different soil layers. If the horizon was fully intact (ie. not burned at all), then mean unburned site values were used for that horizon. Postfire carbon pool from the soil organic layer (kg/m2), calculated from remaining organic layer depths, burn site bulk densities, and carbon concentrations for different soil layers. If the horizon was fully intact (ie. not burned at all), then mean unburned site values were used for that horizon. Estimated density of black spruce trees per m2 for the pre-fire stand. Based on measurements were made by Leslie Boby in 2006 and Jill and Leslie in 2008. Sample areas were 60 sq. m for extensive sites, and 120 sq. m for extensive sites. All trees and saplings that were alive at the time of the 2004 fires are included. Total measured basal area (cm2) of pre-fire black spruce expressed on a per m2 basis. Basal area was calculated from stem diameter at breast height, and only trees >1.4 m were measured. Estimated density of trembling aspen trees per m2 for the pre-fire stand.
