Alternate Identifier:DOI PLACE HOLDER
Abstract:

This dataset contains data from adjacent overwintering and single-season burn sites. For the overwintering fires, we targeted locations that had burned in the summers of 2009, smouldered through the winter months, and reignited in 2010. Adjacent to these overwintering sites, we identified single-season burn sites from within portions of the 2009 fires that were unaffected by overwintering. A total of seven overwintering fire sites and four single-season fire sites were sampled. Within each site, three plots were established. Data inlcudes within plot measurments of post-fire seedling composition and density, residual SOL, burn depth estimated by black spruce adventitious roots, thaw depth, and pre-fire tree species composition and estimates of combustion. This is one of three packages from this project; this one contains the soils data.

Experimental Design

This dataset contains data from adjacent overwintering and single-season burn sites. For the overwintering fires, we targeted locations that had burned in the summers of 2009, smouldered through the winter months, and reignited in 2010. Adjacent to these overwintering sites, we identified single-season burn sites from within portions of the 2009 fires that were unaffected by overwintering. A total of seven overwintering fire sites and four single-season fire sites were sampled. For each site, latitude, longitude, and elevation were recorded with a GPS. Moisture classifcation was based on Johnstone et al. 2008. We estimated maximum stand age by collecting three basal tree disks per site and counting rings. This is one of three packages from this project; this one contains the soils data.

Methods

FIELD: A total of seven overwintering fire sites and four single-season fire sites were sampled. For each site, latitude, longitude, and elevation were recorded with a GPS. Site drainage was determined following Johnstone et al. 2008. A 30m by 2m belt transect was then established at each site. Each transect was divided into three 10m by 2m plots with 2 suplots per transect. The residual soil organic layer thickness (depth of organic soil from surface to mineral/organic interface) and depth of active laer (thaw depth) was measured at each subplot. Burn depth was measured using the adventitious root method adjacent to each subplot, which followed the methods outlined in Walker et al. (2018). The black spruce nearest to each subplot was found, and the height of the upper three adventitious roots from the soil surface was measured. Many of the nearest black spruce trees were fallen, so height of the ARs was measured horizontally from AR to middle of the root ball. The prevalence of paper birch (Betula neoalaskana)-dominated stands did not permit this burn depth estimation so measurements of burn depth are limited to black spruce-dominated stands (n = 3 of 7).
