Teacher Resources – Quadrats Online

Overview: Quadrats Online (Levels 3, 4, 6 & 9)

To assist teachers in delivering a program involving vegetation sampling using quadrats, teacher notes and student activity worksheets have been developed to supplement the use of the Quadrats Online learning object.

Activities have been designed for Levels 3, 4, 6 & 9, however may be relevant for other levels. All activities have been designed to meet Australian Curriculum Science requirements for each level.

A quadrat is a tool used to record the abundance or the density of a particular species in a study area. In some instances it may be possible to simply count the number of organisms of a particular species in an area. However, in most cases, counting all of the organisms would not be practical and other sampling methods are necessary.

Quadrats are often square, circular or rectangular areas, of appropriate sizes that are placed at random in the study area. Presence or absence of species, numbers of organisms or the percentage cover of each species is generally calculated within the quadrat. Quadrats are used to sample plants and may be used to sample some slow moving animals.
