KA 1: field techniques for biologists: sampling of 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
the chosen technique, point count, transect or remote detection must be…
appropriate to the species being sampled
what is a point count?
observer recording all individuals seen from a fixed point count location
this is compared to other point count locations or with data from the same location gathered at other times
what is used to sample plants and other sessile or slow-moving organisms?
-quadrats (of suitable size and shape)
-transects
how are mobile species sampled?
capture techniques e.g. traps and nets
how can elusive species be sampled?
-directly (using a camera trap)
-indirect method (scat sampling)
