- Methods
- Take samples at regular distances (random transect line)
- Randomly generate numbers to correspond to coordinates in a region
- GPS with random generation for deciding locations
- Take samples at regular distances (random transect line)
- Look to see which species are present
- Transect line
- Decide on a line and take quadrat samples along this line
- Biased if decided where to place the line
- Random if the line was generated (or the like)
- Gives a full range of samples
- Decide on a line and take quadrat samples along this line
- Number of samples should correspond to the size of the habitat
- Tree sampling is easier because they can be seen clearly
- Random sampling
- Done to determine
the biodiversity of
an area
- Biodiversity is the
measure of the range
of different species
that live in a habitat
- Biodiversity is the
measure of the range
of different species
that live in a habitat
