The Welsh government has warned farmers they could see their EU subsidies cut after upland farmers argued against the three-tier basic payment scheme.
The upland farming group, Fairness for the Uplands, said the three-tier arrangement was unfair for those farming above 400m.
"Although Welsh Government has been clear that all payment rates were indicative pending establishment of total entitlements under the new BPS, it is inevitable that this revised situation will result in change to the payments that farmers might have expected in the years ahead," said Farming deputy minister Rebecca Evans.
"The budget available for Pillar 1 payments remains as before; some redistribution is therefore inevitable.
"It is also likely that there will be some consequential impacts on our ability to make payments in December 2015."
Fairness for the Uplands’ spokesman Tony Davies, from the Elan Valley, Powys said: “Fairness for the Uplands is a group which has come together overnight in response to the unfairness it was felt upland farmers faced under the proposed method of defining the moorland region.
“The support shown by the members of the group, both in terms of financial support and time spent, has been tremendous. A once disparate group of hill farmers has demonstrated unity in the face of adversity.
“The decision will be welcomed by those who were set to lose money because of the €20 moorland rate, but not so by others with less or no moorland who will receive lower payments as a result of the decision.”
