Below you will find a list and description of the files included in this data publication.


VARIABLE DESCRIPTION FILE (1)

1. \Data\_variable_descriptions.csv: Comma-separated values (CSV) file containing a list and description of variables found in all data files. (A description of these variables is also provided in the metadata below.)

Columns include:

Filename = Name of data file
Variable = Name of variable
Units = Units (if applicable)
Precision = Precision (if applicable)
Description = Description of variable


DATA FILES (3)

1. \Data\allegheny_biomass_deerdays.csv: CSV file containing total browsable biomass and estimated nutritional carrying capacity (i.e., Deer days per hectare) based on six dominant regenerating hardwood species (Acer rubrum, Fagus grandifolia, Fraxinus americana, Betula sp., Prunus pensylvanica, and P. serotina) for sixteen regenerating Allegheny hardwood forest sites in northwestern Pennsylvania. Data are provided as averages by treatment (Fence and Control).

Variables include:

Site = Name of experimental site

Julian Day = Julian date of the sample collection in 2017 (YYDDD)

Treatment = Browsing treatment (Fence, Control [i.e., unfenced])

BB_All = Total browse biomass in grams (stems + leaves) for all species

DD_ha_All = Deer Days per hectare calculated from the FRESH model (Hanley et al. 2012) calibrated using one lactating deer with one fawn

BB_PRPE2 = Total browse biomass in grams (stems + leaves) for just Prunus pensylvanica (PRPE2)

DD_ha_PRPE2 = Deer Days per hectare calculated from the FRESH model (Hanley et al. 2012) estimated using only Prunus pensylvanica data and calibrated using one lactating deer with one fawn


2. \Data\allegheny_nutrition.csv: CSV file containing browsable biomass for both stem and leaf tissue as well as average nutritional quality data (Neutral Detergent Fiber [NDF], Dry Matter Digestibility [DMD], and Digestible Protein [DP]) for sixteen regenerating Allegheny hardwood forest sites in northwestern Pennsylvania. Data are provided by treatment (Fence and Control) and species, for six dominant regenerating hardwood species (Acer rubrum, Fagus grandifolia, Fraxinus americana, Betula sp., Prunus pensylvanica, and P. serotina).

Variables include:

Site = Name of experimental site

Julian Day = Julian date of the sample collection in 2017 (YYDDD)

Biomass = Whether data represent browsable biomass (see Morgan et al. 2019) of either leaf or stem tissue (Leaf, Stem)

Treatment = Browsing treatment (Fence, Control [i.e., unfenced])

Species = USDA Plants Database (https://plants.usda.gov/home) symbol for species in the study
ACRU = red maple
BETUL = birch
FAGR = American beech
FRAM2 = white ash
PRPE2 = pin cherry
PRSE2 = black cherry

Ave_NDF = Average Neutral Detergent Fiber (%)

Ave_DMD = Average Dry Matter Digestibility (%)

Ave_DP = Average Digestible Protein (%) (Tannins, when present, reduces the amount of crude protein available to deer and can result in negative values for digestible protein.)


3. \Data\allegheny_site_info.csv: CSV file containing the UTM coordinates and elevations of all 16 study sites.

Variables include:

Site = Name of experimental site

UTM Zone = UTM zone number and latitude band

Easting = UTM longitude in meters

Northing = UTM latitude in meters

Elevation_m = Elevation in meters


SUPPLEMENTAL FILES (1)

1. \Supplements\allegheny_site_map.pdf: Portable Document Format file containing a map of the Commonwealth of Pennsylvania showing the geographic location of all 16 study sites.
