Gava Field Study Methodology: Managed and Unmanaged Sand Dunes

Transect lines are laid across the managed and unmanaged sand dune ecosystems as shown below. These allow for statistical analysis related to the examination of human impact and the evaluation of dune management strategies. The Mann Whitney u test can be used to compare vegetation biodiversity between similar zones on the two profiles (e.g. dune slacks) or Spearman's Rank to test hypotheses on a single profile (e.g. that vegetation diversity increases with distance inland).
