A deer Industry Environmental Management Code of Practice has been launched by Deer Industry New Zealand chairman Dr Ian Walker.
It was intended to keep the deer industry at the forefront of efforts to improve water quality, Dr Walker said.
"While we strongly encourage farmers to adopt it, we won't have to do much prodding. Most farmers are already highly motivated to have a great environment on their farms."
The new Code built on a Landcare Manual first published by the New Zealand Deer Farmers Association in 2004.
The lead authors were Janet Gregory, from the New Zealand Landcare Trust, and Edmund Noonan, from the New Zealand Deer Farmers Association.
