Question 3

What are some of the risks associated with fieldwork

Answer 3

terrain
adverse weather conditions
contact with harmful organisms
isolation

Question 4

risk assessment
take precautions
work in a safe sensible manner

Question 5

What does sampling allow

Answer 5

sampling will allow you to know what kind of plants and animals are in a particular habitat without having to count every single one

Question 6

What does sampling strategy therefore have to be and include

Answer 6

• efficient and cover enough area to give a good representation of your habitat
• include bot biotic and abiotic factors so you can determine any relationships, differences in ares or changes over time

Question 7

How do we sample biotic factors

Answer 7

quadrats
pitfall traps
Transect line
kick sampling
Tree beating
Sweep nets
point counts
camera traps
scat sampling

Question 8

What are sampling and abiotic factors

Answer 8

soil sampls, pH meters, moisture metres, thermometers, anemometers, oxygen probes, humidity, water velocity

Question 9

What should sampling always do

Answer 9

be apprpriate to the relevant organism

minimise impact on wild species and habitats

consideration should be made into rare and vulnerable species and habitats that are protected by legislation.

Question 10

a point count involves …

Answer 10

observation and recording of individuals from a fixed point location

this can be compared to other point locations or with data from the same location gathered at other times

Point counts are a common way to gather info on bird populations
