Extended Data Fig. 6: Schematic demonstrating matching procedure.
From: Protected areas have a mixed impact on waterbirds, but management helps
Example of the matching procedure for one species, using a toy dataset of 6 protected sites (A to F) and 3 unprotected sites (X, Y and Z), with three dummy example covariates, climate (cloud), land use (wheat) and human population (person). See methods, ‘Matching’ for a more detailed step by step walk through of this process.
