OPIHI: Introduction to Sampling
Field ecology is a great way to introduce students to scientific methodology, as well as to concepts like biodiversity, zonation, and invasion biology. It simply isn't possible to examine or count every organism in an area, but sampling using representative amounts or sections of an area to estimate the composition of a larger site, can be a challenging concept.
We have developed several techniques to help introduce students to
sampling, and enable them to carry out studies of species richness
and abundance. The first activity (Introduction
to Sampling: Jellybeans) is an introduction to sampling in
general and the power of the strategy. The second activity (Card
Safari) is an introduction to sampling for diversity, followed
by the third activity (Measuring Abundance with
Transects and Quadrats) describes sampling for abundance.
