Why do we use quadrats and transects?
Keeping this in view, why do we use transects?
Line transects are used when you wish to illustrate a particular gradient or linear pattern along which communities of plants and, or animals change. They provide a good way of being able to clearly visualise the changes taking place along the line.
One may also ask, why do we use Quadrats? It is impossible to count all the plants in a habitat, so a sample is taken. A quadrat is often used to sample plants. It marks off an exact area so that the plants in that area can be identified and counted.
Hereof, why would you use a transect instead of a Quadrat?
A gradual change in the distribution of species across a habitat is called zonation. It can happen because of a gradual change in an abiotic factor. A transect is usually used to investigate a gradual change in a habitat rather than to simply estimate the number of organisms within it.
What is the transect method?
A transect is a path along which one counts and records occurrences of the species of study (e.g. plants). It is less effective than other methods, such as the Belt Transect.
