All practical work involves the identification of ___ and ___.
hazards and risks
Hazards in fieldwork include…
adverse weather,
difficult terrain,
problems associated with isolation,
contact with harmful organisms.
stepping on a frog,
running out of cereal bars
What is risk?
Risk assessment involves…
the likelihood of harm arising from exposure to a hazard.
identifying control measure to minimise risk
Risk-controlling measures include…
appropriate equipment, footwear, clothing and means of communication (eg radio)
Sampling should be carried out in a manner that…
minimises impact on wild species and habitats
When taking a sample, consideration must be given to ___ and ___ species and habitats which are protected by ___.
rare and vulnerable, legislation
Name the three sampling techniques for wild organisms.
The chosen technique must be ___ to the species being studied.
point count, transect, remote detection.
appropriate
Describe the point count technique (2).
point count involves an observer recording all individuals seen from a fixed point count location.
Data can be compared to other point count locations, or the same one at different times.
What is a transect?
What is remote detection?
a line along which samples can be taken (good for areas with variable abiotic factors / terrain.
When cameras go boo!
Which capture methods are used for plants or slow moving organisms?
quadrats and transects
Which capture techniques are used for moving organisms?
traps and nets
Elusive species (like Badgers) can be sampled directly using… or indirectly using…
directly using camera traps
or indirectly using scat sampling
