For relocation error, vegetation plots can be divided into permanent and non-permanent plots, while the latter are further divided into quasi-permanent (with approximate relocation) and non-traceable (with random relocation within a sampled area) plots. To reduce the inherent sources of error in resurvey data, the following precautions should be followed: (i) resurvey historical vegetation plots whose approximate plot location within a study area is known, (ii) consider all information available from historical studies in order to keep plot relocation errors low, (iii) resurvey at times of the year when vegetation development is comparable to the historical survey to control for seasonal variability in vegetation, (iv) retain a high level of experience of the observers to keep observer bias low, and (v) edit and standardize data sets before analyses.
