Environmental groups that do not exist have been promised funding by the Napthine government ahead of the state election.

Environment Minister Ryan Smith and Yan Yean Liberal candidate Sam Ozturk announced last week that eight Landcare groups in one of the state's most marginal seats would receive $160,000 if the Coalition was re-elected.

But Diamond Creek and Wattle Glen and District Landcare, who were promised $15,000 each, do not exist.

The blunder has drawn criticism from Victorian Greens leader Greg Barber, who said the Coalition and Labor had no environmental policies.
