- Notes:
- Bergner: "The regional climate is cold and dry. Mean monthly temperatures range from −20°C in January to 16°C in July. July is the wettest month, with an average of 690 mm rain. Winter months are driest, with averages of 80 mm precipitation per month, mostly as snow (http://weather.noaa.gov/). The growing season lasts from mid-May to early September." Allison: "[7-9 years post-fire] the dominant plants were herbaceous perennials, deciduous trees, and shrubs; major plant taxa included Betula, Calamagrostis, Festuca, Ledum, Lupinus, Populus, Salix, and Vaccinium as described by Mack et al. (2008)." [Elevation queried from lat lon using R geonames::GNstrm3.]
- Soilnotes:
- Bergner: "Soils are well drained, alluvial gravels overlaid by silt. Permafrost is discontinuous in this region, and no permafrost occurs under our sites." Allison: "Soils are well-drained and consist of a shallow organic horizon (<5 cm depth) underlain by a silt-loam mineral soil (A horizon) derived from gravelly glacial till and outwash (Harden et al., 2006; Waldrop and Harden, 2008). The 1999 fire removed ∼60% of the surface organic C, leaving behind an unburned forest floor horizon approximately 0–3 cm thick (King et al., 2002)." [Harden et al., 2006: J.W. Harden, K.L. Manies, M.R. Turetsky, J.C. Neff Effects of wildfire and permafrost on soil organic matter and soil climate in interior Alaska Global Change Biology, 12 (2006), pp. 2391–2403] [Waldrop and Harden, 2008: M.P. Waldrop, J.W.
