Students carried out a vegetation succession investigation along a transect from the shoreline across a sand dune system. They recorded the percentage cover of different plant species using a quadrat at regular 20 m intervals. A sample of their data is shown in the table below:
| Distance from Strandline (m\text{m}m) | Sea Couch (%) | Marram Grass (%) | Heather (%) |
|---|---|---|---|
| 20 | 55 | 10 | 0 |
| 40 | 20 | 65 | 0 |
| 60 | 5 | 40 | 10 |
| 80 | 0 | 15 | 45 |
| 100 | 0 | 0 | 80 |
Which of the following graphical representation methods would be the most appropriate to display the spatial distribution and changing abundance of these species along the transect simultaneously?
Kite diagram
Isoline map
Choropleth map
Radial diagram
