Results and analysis:

Draw up the following tables and graphs: 

Belt transect:

1. Table of the raw data.
2. Table to show the how plants vary across the transect for % cover, species number and composition per quadrat.  Include bare earth and rock.
3. Profile to show plant heights.

Line transect:

1. Table of the raw data.
2. Table to show the how plants vary across the transect - species number and composition per quadrat. 
3. Profile to show plant heights.

Analysis:

1. Summarise the results for each method.
2. Compare each method:
   
   • Do they tell the same story?
   • Which provides the most suitable data?
   • What are the pros and cons for each method?
   • Which method would you adopt?
   • Can you improve on these methods?  Suggest how you might do this?
