Comparing National-Scale OPDs from Three Methods with Field Trial Results

In this review, we compared the national-scale OPDs obtained from the three main methods with the results of the field trials. This comparison highlights the strengths and limitations of each method for assessing biodiversity at a national level. The study provides valuable insights into the accuracy and applicability of different approaches for measuring OPD, contributing to a more comprehensive understanding of plant diversity patterns across large geographical areas.
