Quadrat - belt transect
The belt transect method is used when there is a gradual change from one side of a habitat to another, like the change in light between the outer edges of a forest to the centre.
- Extend a measuring tape from one side of the habitat to another.
- Place a quadrat at 0m on the tape.
- Count the numbers/estimate percentage cover of each species.
- Use a key to identify each species.
- Record results in a table.
- Move the quadrat along the measuring tape.
- Repeat step 3-5 at regular intervals along the measuring tape.
- Continue until the full length of the measuring tape has been sampled.
- Calculate the average of each species.
- A bar chart can be drawn to show the data obtained.
