Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
This file contains all the vegetation measurements taken at each camera station pair. Cameras were set up in the Summer and Fall seasons of 2013 and 2014 on the grounds of the Smithsonian Conservation Biology Institute in Front Royal, VA USA. Cameras were only established in forest habitat. Camera stations were made up of pairs of cameras, one at a log feature or game trail, the other at a random nearby location. Vegetation measurements were taken at the midpoint between the two cameras. In addition to the PairID, Grid location, and vegetation sampling date, 4 vegetation variables are included. "CovAll" is the overall level vegetative cover percentage recorded as the average percent of a 2-m high cover pole obscured from 10 m away in each cardinal direction. Cover pole was divided in 20 1-dm sections. Data were recorded as the percentage of 1-dm sections obscured ( >50%) by vegetative or structural cover. "CovLow" is the average percent of low portion (<0.5 m) of cover pole obscured by vegetative or structural cover. "UnderStem_D" is the number of woody stems >1.5 m in height and <7.5 cm dbh counted within 3 arm's-length transects, divided by 33 square meters. Transect were parallel, 20-m transects extending perpendicular to the aspect of the plot. Transects were placed both through the actual sampling location as well as 10 m up and down slope of location."OverStem_D" is the number of woody stems >7.5 cm dbh counted within 3 arm's-length transects, divided by 33 square meters. Transects used were same as for "UnderStem_D".
