0 \(\le\) x \(\le \infty\)

Cervid_Facilities

Number of privately owned premises in the management area that maintain cervids in captivity for the purposes of breeding, farming, display, and/or enclosed (fenced) hunting operations known to the wildlife agency in the given season-year or in the most recent prior season-year for which the number is known³³

Total_harvest

Number of wild white-tailed deer harvested by hunters in the management area in the season-year or in the most recent prior season-year for which the number is known and reported to the wildlife agency³³

Streams

Average distance in meters from any location within a management area to the nearest high order stream (Strahler order 4 or greater) as defined in the National Hydrography Dataset (NHD) Plus; derived by intersecting the NHD Plus and USCB Cartographic Boundary File³³

Proportion

0 \(\le\) x \(\le\) 1

Percentage

0 \(\le\) x \(\le\) 100

Clay_percent

Average percentage of clay in the upper 50 cm of soil, as calculated using the clay content at standard depths³³
