Methods for sampling animals include using a pooter for small insects, sweep nets for grassland insects, pitfall traps for ground-dwelling invertebrates, tree beating for arboreal invertebrates, and kick sampling for river organisms.

| Back | sampling animals - pooter (suck on mouthpiece, insects drawn into holding chamber, filter before mouthpiece prevents sucking into mouth, used for small insects) - sweep nets (catch insects in long grass) - pitfall traps (hole dug in ground and covered with roof structure to prevent filling with rainwater, used for small, crawling invertabrates) - tree beating (large white cloth stretched out under tree, tree shaken to dislodge inverterbrates which fall on sheet, used for invertabrates living in tree/bush) - kick sampling (river bank and bed kicked to disturb substrate, net held downstream to capture organisms released in flowing water, used for organisms living in river |
