biology - 2.1b - sampling wild organisms Flashcards
How should sampling be carried out?
In a manner that minimises impact on wild species and habitats.
What must consideration be given to?
Rare and vulnerable species and habitats that are protected by legislation.
What must the chosen technique, point count, transect or remote detection be appropriate to?
The species being sampled.
What does a point count involve?
The observer recording
all individuals seen from a fixed point count location.
What can the observer recording individuals seen from a fixed point count location be compared to?
Other point count locations or with data from the location gathered at other times.
What are quadrats, of suitable size and shape, or transects used for?
Plants and other sessile or slow-moving organisms.
What are capture techniques, such as traps and nets used for?
Mobile species.
How can elusive species be sampled?
Directly using camera traps or an indirect method, such as scat sampling.
