Simple random design

e.g. using random grid coordinates

2

Systematic random

sampling locations are arranged in a regular pattern e.g. grid or checkerboard
(produces more precise estimate of stable variables)

3

Clustered random

cluster centres located at random + then sample units w/in each cluster are also located at random

4

Pattern, 2017

ear tuffs are a robust feature for rhino identification

5

Cinkova, 2014

rhino contact calls can be used to identify individuals

6

Alibhai, 2008

footprints can be used to identify individual rhinos

7

Footprint Identification Technology (FIT)

accurately identifies individual animals through photo of footprint (Wildtrack, 2018)

8

Tende et al., 2014

Individual DNA-identification of lions can be used from DNA samples found in saliva, faeces and hair

9

Ground counts

walked or driven transects

10

Call back surveys

device plays a sound (e.g. injured prey) that attracts predators to enable data collection

11

VHF collars

a.k.a. Very High Frequency
~ emit pulsing radio signals which allows the animal to be located

12

GPS tracking collars

allows for remote detection and stores the animals location data either in the collar or downloaded remotely

13

Allodiveristy

introduced diversity

14

Distance effect

immigration + emigration affected by distance from colonist sources
(Further away = more travel time = less likely)

15

Rescue effect

decrease in isolation = decrease chance of extinction due to increased chance of immigration

16

National parks act as...

metaphorical islands
