But he said the MoD was "very proactive" in keeping locals informed about the risks of wildfires and any ongoing problems on their land.
Aside from the problem of live military training sparking fires, old unexploded ordnance left behind from previous manoeuvres make wildfires harder to fight,
This month has seen a major fire burning on Langdale Moor, in the North York Moors National Park, since Monday, 11 August.
It has seen a number of bombs explode in areas that were once used for military training dating back to the Second World War.
One local landowner, George Winn-Darley, said the peat fire had produced "an enormous cloud of pollution" that could have been prevented if there had not been live ordnance on site.
"If that unexploded ordnance had been cleared up and wasn't there then this wildfire would have been able to be dealt with, probably completely, nearly two weeks ago," he told the BBC.
Mr Winn-Darley called for the MoD to clear up any major munitions left on the moors.
"That would seem to be the absolute minimum that they should be doing," he said.
"It seems ridiculous that here we are, 80 years after the end of the Second World War, and we're still dealing with this legacy."
A MoD spokesperson said the fire at Langdale had not started on land currently owned by the MoD but that an Army Explosive Ordnance Disposal (EOD) team had responded on four occasions to requests for assistance from North Yorkshire Police.
"Various Second World War-era unexploded ordnance items were discovered as a result of the wildfires, which the EOD operator declared to be inert practice projectiles. They were retrieved for subsequent disposal," he explained.
He added that the MoD monitors the risk of fires across its training estate throughout the year and restricts the use of ordnance, munitions and explosives when training is taking place during periods of elevated wildfire risk.
"Impact areas" are constructed with fire breaks, such as stone tracks, around them to prevent the wider spread of fire and grazing is used to keep the amount of combustible vegetation down.
Earlier this month, the MoD launched its "Respect the Range" campaign, designed to raise the public's awareness of the dangers of accessing military land, such as live firing, unexploded ordnance and wildfires.
A spokeswoman for the National Fire Chiefs Council (NFCC) said it worked closely with the MoD to "understand the risk and locations of munitions and to create plans to effectively extinguish fires".
"We always encourage military colleagues to account for the conditions and the potential for wildfire when considering when to carry out their training," she added.
