The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures
Four pairs of 10 m x 10 m permanent plots were established in two unique locations. The two locations are characterized by relatively level terrain with a mixed oak overstory. The fenced and unfenced paired plots are separated from one another by a 5m buffer. The unfenced and fenced treatments were randomly assigned to the plots at each location. Fenced treatment plots were enclosed by a 2.5m-tall fence. A small (~25cm x 25cm) hole was cut at ground level on each side of the fence to allow smaller animals access to the fenced area. To permanently identify the unfenced plots, all four corners were marked with metal fence posts. A corner of origin was identified (to facilitate locating trees, saplings, etc. in the following years using a grid system). Sampling occurs in the summer, ideally in July, on the year of installation and every 5 years afterwards.
All individuals whose growth habits are designated as “tree” by the New York Flora Atlas, who are between 0.5 and 2 m tall with at least 50% of their stem(s) emerging from the ground inside of the plot will be evaluated in the sapling layer the year of exclosure installation and every 5 years afterwards. Each stem that emerges from the ground at a distinct location is considered a sapling. Saplings are tagged and assigned a number. The coordinate position (X and Y distance from the designated “origin”, in meters) is measured, primarily so that researchers can find saplings whose tags have fallen off between monitoring rounds. The presence/absence of browse, species, and undisturbed height (cm) to the tallest bud (without stretching the shoot) are measured.

- Site Description
To evaluate the impact of deer overabundance in the mixed upland oak forests of Mohonk Preserve, four paired plots were established in various vegetation stands. The plots contain red oak, chestnut oak, sugar maple, American hophornbeam, witchhazel, and shagbark hickory. Two plots are in the northeastern portion of the preserve, and two are in the southwestern portion. All plots are relatively flat with a closed canopy and few rocks.
