1. Wildlife Management / Small Mammal Trapping!

2. Population
DNR is always estimating the population of wildlife to determine how best to manage a species.
Duck
Deer
Pheasants
Walleye
ect.

3. Methods to Determine Population
1. Actual Count (96 deer in Bunker Hills 2016) 2. Quadrat Method 3. Line Transect Method 4. Mark and Recapture

4. Quadrat Method 1. 3 2. 2 3. 0 4. 3 5. 4 1 ______ 14/ 6 = 2.33
1. 3
2. 2
3. 0
4. 3
5. 4 1
______
14/ 6 = 2.33
2.33 x 30 = 70

5. Line Transect
Used to determine the change in a population over time

6. Mark and Recapture A simple way to estimate a population of mobile species.

7. How to Estimate Population
How to Estimate Population N = M (T) / P N = Estimated Population Size M = Number of originally marked mice. (day 1) T = Total Number of Mice 2nd trapped P = Number of 2nd trapped mice that were marked

8. Mark-Recapture Practice
Data:
Total Number Caught & Marked Day 1 = 17
Total Number captured on Day 2 = 12 Total Number captured 2 day that were marked = 8 Calculate the Population:
N = (17x12)/8
N = 25.5
N = Estimate of total population size
M = Total number of animals captured and marked on the first visit
C = Total number of animals captured on the second visit
R = Number of animals captured on the first visit that were then recaptured on the second visit

9. Benefits of Small Mammals
Small mammals play crucial roles in natural ecosystems. They serve as predators, prey, seed dispersers, pests, and grazers.
Small mammals can keep pest species down, both insect and vertebrate, and can serve as food for larger game species.

10. Why Trap???
Most small mammals will never be easily observed in the wild. They may be nocturnal, crepuscular (active at dawn or dusk), or simply too well camouflaged to notice.
Live-trapping provides the best way to survey a population without harming them.
