Funding for four greyhound racing tracks should end, according to a new report into the future of the industry.
These are Enniscorthy, Lifford, Longford and Youghal.
A review of the future needs of 16 licensed stadiums in Ireland has been published by the Irish Greyhound Board (IGB).
In a statement, it says it accepts the recommendations of the report.
The independent report was undertaken by Indecon Economic Consultants, and was a key element of the IGB's Strategic Plan up to 2022.
It also examined financial sustainability at each track, population catchments and motorway access.
The report has recommended a restructuring of the footprint of the greyhound sector, ongoing cost efficiency measures and targeted investment in animal welfare.
In terms of track funding, it notes that the four tracks concerned have "each contributed significantly to the Irish greyhound industry over a long number of years.
"Each track has been in operation for over half a century, with each one having a unique history, culture and tradition."
The IGB adds that it "very much regrets the decision to cease funding" at these stadia and its impact on staff, owners and the wider greyhound community.
Bit it says it is "keenly aware of the challenges that Indecon Economic Consultants have identified for the industry."
