• Land consolidation is one of the major land-use changes in Japanese agricultural systems.
• We examined the relationship between the occurrences of farmland consolidation and threatened plant species across Japan at the prefecture scale.
• Results show that areas containing records of threatened plant species had rarely experienced consolidation.
• We concluded that consolidated farmland areas have experienced/undergone a long-term negative impact on plant species diversity.
