"Some of the images being shared are not from this winter and many don't appear to be in Southland."
The council took problems related to winter grazing seriously and was working to support farmers in achieving good practice or taking compliance action where necessary, he said.
The council relied on inspections and reports from the public to identify properties where poor practices might be happening.
The first of its planned aerial inspections was carried out last week and found a good level of compliance with only three properties identified as requiring further investigation.
So far this season, the council investigated 18 incidents related to intensive winter grazing with only one confirmed breach and three still under investigation.
During the past year, Environment Southland had undertaken a great deal of work alongside industry agencies, including Federated Farmers, to support farmers to lift their winter grazing performance, Phillips said.
The council was also working closely with the Ministry for Primary Industries.
"This council is a big believer in working with others to get the best outcomes for Southland. By pulling together we achieve so much more," he said.
Another aerial inspection was scheduled for the end of the month and an animal welfare inspector from MPI was expected to be part of the compliance team on that flight.
