Quadrats - factors to consider

  • Size of quadrat
  • Number of sample quadrats to record with the study area
  • the position of each quadrat with study center

Random sampling - using random number generator to decide on co ordinates to place quadrat on - reduces influence of human bias.

Transects - tape stretched across in straight line - anything on this line recorded - useful for when some form of transition in th community takes place so distribution of species is systematic
