A wildfire has now been burning for more than a week, with emergency services still working to bring it under control on day nine.
The blaze near Blaenavon has drawn a major response from crews, who are tackling the fire with support from Natural Resources Wales (NRW) and contractors.
The Welsh Government has defended the emergency response following calls for aerial support, saying in a letter that helicopters were requested but ultimately not needed.
Sian Gwenllian, cabinet secretary, said in a letter to MPs Nick Thomas-Symonds and Lynne Neagle that aerial support had been requested through Natural Resources Wales but was "no longer required" and that helicopter availability remains limited across the UK due to exceptionally high demand.
Crisis management arrangements have been activated by the Welsh Government, who continue to work closely with fire services and partner agencies.
South Wales Fire and Rescue Service said crews are making "good progress" despite the blaze still burning.
A spokesman for South Wales Fire and Rescue Service said: "We are incredibly grateful for the public's generosity and support.
"However, for your safety please avoid the area and refrain from bringing food and refreshments to crews, as all welfare arrangements are already in place."
