Just under 400 deer have been culled in Killarney National Park in 2025, according to figures from the National Parks and Wildlife Service.
The majority of wild deer culled in the 10,000-hectare park in Co Kerry were non-native sika deer.
The figures show that 116 native Killarney red deer and 276 sika deer were culled this year.
It is a rise of 37% from last year, when a total of 286 deer were culled.
The culling mainly took place during the official hunting season and the focus was on culling female deer.
However, local representatives have said wild deer in Killarney are found beyond the park and number in their thousands.
Killarney councillor Brendan Cronin said road collisions with deer are now a regular occurrence.
The independent councillor said he has highlighted the issue of increasing numbers of deer and road incidents on national roads near Killarney.
He called for "fencing, restriction and responsibility to be taken by the NPWS".
"Deer are a huge road traffic issue now in Kerry and are jumping out onto the bonnets of cars. They are in every direction, miles outside the National Park," Cllr Cronin said.
"Unlike farm animals, no one is held responsible when there is a collision with these huge animals and there is no comeback.
"This is totally wrong and needs to be addressed. The National Parks and Wildlife Service has to take responsibility for car accidents and damage," he said.
The NPWS said it acknowledges there was an increase in deer numbers during the Covid-19 pandemic when hunting was restricted.
A spokesman said deer populations are mobile and have a home range that is not constrained by land ownership boundaries.
The NPWS said a deer management strategy, set up under the Department of Agriculture, Food and the Marine, aims to address issues of controlling the deer population.
Under the strategy, managed by Farm Relief Services (FRS), deer management units with coordinators have been appointed across the country.
The coordinators liaise between farmers and hunters to deal with problem areas.
Farm Relief Services Deer Management Unit Coordinator for Kerry and Cork James Coffey said practically the whole of Kerry is a problem area for deer and the aim is to bring landowners together to deal with the issue.
He urged landowners to reach out to the FRS and to seek assistance.
Mr Coffey said the strategy is aimed to be proactive rather than reactive.
"We are trying to manage the deer. Every area is different, " Mr Coffey said.
