The following is just a note for me to be able to comprehend the code line in the future when field names might change: aggregate('NAME OF THE REFERENCE LAYER', 'concatenate', "FIELD NAME FOR THE RED LIST STATUS IN THE REFERENCE LAYER", "FIELD NAME FOR THE SPECIES IN THE REFERENCE LAYER" = attribute(@parent,'FIELD NAME FOR THE SPECIES IN THE REFRENCING LAYER'))
