Visitor Use and Activities Detected Using Trail Cameras at Forest Restoration Sites

Figure 5.

Results of simulated surveys of site visitation constructed by rarefaction of trail camera data at the Bluffton Native Habitat Waterway, Bluffton, Indiana, and Deetz Nature Preserve in New Haven, Indiana, during the summer of 2016. Results are the number of consecutive days of sampling needed to accurately estimate the mean number of daily visitors. Points show daily visitor counts from individual simulations (points are jittered horizontally for visibility). Red lines show the standard error of the simulated mean number of daily visitors. Horizontal black line and grey area show overall mean and 95% confidence interval (CI) calculated from all data using all possible days. Vertical dashed line indicates the minimum consecutive days of sampling needed to accurately estimate the number of daily visitors as being within the actual 95% CI. A) Bluffton Bridge, B) Bluffton Driveway, C) Bluffton Parking Lot, D) Deetz Parking Lot (Deetz=Deetz Nature Preserve, Bluffton=Bluffton Native Habitat Waterway).
