A record 1.75 million Bavarians signed a petition to seek a referendum to "save the bees", a move that could have huge consequences for the German farming industry and environmental protection.
The proposal for a vote to protect species diversity sets a target to have 20 percent of farmland meeting organic standards by 2025, before reaching 30 percent by 2030.
Ten percent of green spaces in Bavaria should also be turned into flowering meadows, while rivers and streams must be better protected from pesticides and organic fertilisers.
The number of people who descended on city halls across the state to sign the petition far surpassed the one million required to obtain a referendum within six months, under the state's direct democracy system.
It also came despite opposition from the powerful regional farmers' association, which has urged the population to "stop bashing farmers" and warned of the potential financial costs to the industry.
The petition also puts the Bavarian government led by the CSU -- sister party of Chancellor Angela Merkel's CDU -- under intense pressure, as it counts farming communities among its staunchest supporters.
