What is a Belt Transect?

• A way of sampling the effect of an abiotic factor on the distribution of organisms

• A way of sampling a non-changing habitat

What is the best way to place a quadrat?

• Place it where you like

• Divide the sample area into a grid and use a random number generator to choose a square.

• Throw the quadrat so it's random

• Divide the sample area into a grid and choose a square.
