Two iconic ghost gums that feature in many of the paintings by famed Indigenous artist Albert Namatjira have been destroyed by fire.
The trees, about 20 kilometres from Alice Springs, were featured in numerous works by Namatjira and helped establish his place in the international art world.
It is believed the fire that destroyed the trees was deliberately lit several days ago.
The site, which is easily accessible on the road from Alice Springs to Hermannsburg, where Namatjira was born, was a popular place for tourists.
"I just think it is a sad time in the Territory's history," she said.
Ms Anderson says she hopes the trees can be re-grown.
"I think that if the root system is still alive ... there can be regrowth," she said.
"After a lot of rain it'll come back to life again.
"But I just don't think it is nice for someone to go around burning such iconic trees, because it is our heritage."
However Northern Territory Police say they cannot investigate the suspected arson because it was reported too late.
Bushfires NT says the fire last week was deliberately, but police say five days passed before they were notified and the crime scene has not been preserved.
Ms Anderson says more needs to be done and she will raise the issue with Chief Minister Terry Mills.
"I think that we need to follow these cases through because we can't just allow these nuisance people to roam around in the community with a match or a cigarette lighter, because they might do it to something else and these trees were famous," she said.
Namatjira first came to the notice of Australian art circles in the late 1930s and by the 1950s had won international acclaim.
He died in 1959.
