Site Location and Environmental Characteristics for 83 Locations of 6-163 Years Old Black Spruce, Alaska Paper Birch, and Aspen Stands Accoss Interior Alaska. Sampled in 2008-2010 and 2013-2015.

This dataset contains the GPS location, slope, orientation, elevation, forest type based on dominant tree biomass, Age, sampling year, total vascular cover, total lchen cover, deciduous index (Alexander et al. 2012, Ecosphere), basal area of black spruce, Alaska paper birch, trembling aspen, large deciduous shrubs and trembling aspen, organic layer depth, pH, heatload, approximated moisture class for all sites (Johnstone et al. 2008), gravimetric moisture content, and volumetric moisture content. This dataset was part of the site-level covariates used in a study of bryophyte post-fire succession in deciduous and coniferous successional trajectories. NOTE: there is some overlap between the >20 years old sites that were sampled by Heather Alexander with some of the data she submitted in relation to her 2012 Ecosphere paper.

Hubbard Brook Experimental Forest: Diversity of Forest Floor Vegetation under Ash, Beech, Sugar Maple, and Yellow Birch, 2021

As the interface between plants and soil, the organic horizon is the foundation of forest ecosystems. Two potential predictors of O-layer properties, vegetation and mineral soil type, are difficult to separate because they typically covary. We conducted a factorial study involving four canopy tree species and two soil types with distinctly different hydrology and topographic position to parse patterns in chemistry and microbiota of the O-layer in a north-temperate deciduous forest. There were frequent strong effects of tree species. White ash frequently differed from the other trees: e.g., lower cation exchange capacity and exchangeable acidity, thinner Oi layer, lower %C and C:N, and, from phospholipid fatty acids, more AM fungi and less gram+ bacteria. These patterns, presumably due to species-specific attributes of leaf litter quality, root exudates, and microbial associations, must arise over decades, given that the stands in the study age between 85 and 100 years. We also found patterns in the O-layer related to underlying soil type, independent of tree species: e.g., Bh podzols, compared to Typical podzols, had higher trace metals, thicker Oa layer, and more AM fungi. Relations between mineral soil type and the organic layer, which were larger than expected, could arise because landscape features that influence hydrology and therefore soil formation over millennia also influence biogeochemistry of the organic layer over decades. It could also involve bioturbation by organisms across horizons. There is basic and applied value in models that can predict properties of the O-layer based on vegetation and soil types.

Tree regeneration after fire: Wickersham Dome long-term vegetation study, birch height data

These data represent the most recent set of observations (made in 2002 by J. Johnstone) for several long-term vegetation monitoring plots near Wickersham Dome that were set up by Les Viereck and Joan Foote following the 1971 wildfire and 1978 experimental burns. Earlier records are available in the BNZ long-term vegetation database. This dataset documents tree seedling/sapling and shrub measurements made in 2002. Lists heights of all individual paper birch (Betula papyrifera) present in a plot.

High-resolution surface wind observations over complex terrain: Big Southern Butte, Salmon River Canyon, Birch Creek

This dataset contains high-resolution wind observations from three field campaigns that took place during 2010-2014 at Big Southern Butte, Salmon River Canyon, and Birch Creek, Idaho. There are three SQLite databases containing 30-s averaged 3-m wind speed, wind direction, and wind gust data from 30-90 cup-and-vane anemometers over a period of 2-4 months at each field site.

Birch NPP: Tree density and basal area by diameter sizeclass in upland and flooplain mid- and late-successional stands: 1989-2008

This data set is derived from BNZ LTER inventory plots. Stand density and basal area are listed by diameter size class of live Alaskan paper birch trees for each replicate stand within mid- and late- successional upland upland and landscapes by year from 1989-2008.

Birch NPP: average NPP per tree by diameter sizeclass for 4 time periods between 1993 and 2008

This data set is derived from BNZ LTER inventory plots, where DBH of all trees is measured every 3 to 4 years, and increment changes in AG biomass are derived from allometric equations. Data included in this file were obtained from 1993, 1997, 2000, 2004 and 2008 inventories, generating 4 growth increments between 1997 and 2008. Data are reported by diameter sizeclass (10 cm increments), and include NPP increments (averaged across all trees within each landscape and successional stage) for which adequate numbers of trees (typically >5) were present to obtain useful measurements (see N in data file).

Alaska paper birch NPP per tree calculated from dendrometer bands annually from 1994 to 2008

This data set is derived from BNZ LTER inventory plots, where band dendrometers are in place on trees within each diameter size class (typically 10 trees per 10 cm increment diameter size class). Dendrometer bands are read in the fall each year. Biomass is calculated from allometric equations, from which annual biomass increments are derived. Data are reported as the average annual growth per tree across all trees within a given landscape and successional stage and reported as kg biomass/tree/year.

Whole Genome Sequencing of birches (Betulaceae: Betula) from the Kenai Peninsula, Alaska

We sought to learn more about the identity of Betula kenaica W.H.Evans, the Kenai birch, which has remained somewhat enigmatic since its description in 1899. Tissue samples were collected from two birch specimens on August 12, 2019. Cuttings were taken from a B. kenaica individual ("BK01" in this dataset, <a href="https://arctos.database.museum/guid/KNWR:Herb:11553">https://arctos.database.museum/guid/KNWR:Herb:11553</a>) from Kasilof Beach, Kasilof, Alaska, one of the two type localities of B. kenaica. Cuttings were also taken from a Betula pendula subsp. mandshurica (Regel) Ashburner & McAll. individual ("BP01" in this dataset, <a href="https://arctos.database.museum/guid/KNWR:Herb:11556">https://arctos.database.museum/guid/KNWR:Herb:11556</a>) from Soldotna, Alaska. The cuttings were shipped to SNPsaurus (Eugene, Oregon, USA, <a href="https://www.snpsaurus.com/">https://www.snpsaurus.com/</a>) for whole genome sequencing. This dataset includes specimen collection data, the sample sample submission form, and the three files delivered by SNPsaurus.
