Slide1

Effect of Human Activity on Deer Frequency in the DePauw University Nature Park

Amanda Faulkenberg and Caitlin ClearySlide2

Introduction

Idea

Motivation

Previous ResearchSlide3

Connection to Conservation

Are humans going to negatively affect deer?

humans are a perceived threatSlide4

Hypotheses and Predictions

Deer trails will be more abundant in the study area further from the human hiking trails compared to those plots found in the area closest to the trails.

More deer photographs will be captured on the camera traps in the plots with the most trails and further from human activity. Slide5

Study Location and Species

DePauw Nature Park

Quarry Hillside

Quarry South

5 plots in each area (randomly selected)

White-tailed deerSlide6

Methods: Trail Calculation

Trail Length

Average Trail

Width

Total Trail AreaSlide7

Methods: Plot and Camera Locations

Randomly selected 5 plots in Quarry Hillside and Quarry South off of the grid maps.

Flagged and labeled each corner to the plots (NW, NE, SW, SE)

Chose 4 of 5 plots in Quarry Hillside and Quarry South to place cameras in.Slide8

Quarry Hillside and Quarry SouthSlide9
Slide10
Slide11

Methods: Photograph Data

8 cameras total

4 in Quarry Hillside

4 in Quarry South

Located in each

plot along deer

trails (roughly ten

meters away)

Cameras used:

MoultrieSlide12

Statistical Analysis

Kruskal-Wallis Nonparametric Test Slide13

Results: Trails

Significantly more total deer trail area in the Quarry South Plots (Kruskal-Wallis, p=0.008)Slide14

Results: Photograph Data

Not Significant (Kruskal-Wallis, p=0.057)Slide15

Supplementary Data: Leaf LitterSlide16

Supplementary Data: Time of movementSlide17

Supplementary Data: Trees

Significantly more trees in the Quarry Hillside plots (Kruskal-Wallis, p=0.008)Slide18

Conflicting results

Many trails in Quarry South but small number of deer.

Many deer in Quarry Hillside but small amount of trails.Slide19
Slide20

What Next?

Consistent Cameras?

Implications of the understory

Use of man-made trails

Tree obstructionsSlide21
