Exercise 5.

• what is the most commonly used type of sampling method that is likely applicable for land plants?

  plot sampling
• This type of sampling are advantageous and efficient in studies of contiguous stages in ecological succession or of communities at transition zones.

  Transect sampling
• What is the technique used for estimating the population sizes of smaller organisms such as herbs?

  line intercept
• What is the number of individuals in a unit area?

  Density
• what is the number of individuals of a given species as the proportion of the total number of individuals of all species?

  Relative density
• This is the chance of finding a given species within a spot

  frequency
• this is the frequency of a given species as a proportion of the sum of the frequencies of all species.

  relative frequency
• what is the proportion of the ground occupied by a vertical projection to the ground from the aerial parts of the plant?

  coverage
• this is the coverage for that species expressed as a proportion of the total coverage

  relative coverage
