Dozens of trees, including at least one Norfolk pine, have been targeted in a mass poisoning along a Sunshine Coast beachfront walkway.

Council teams have now scoured the area to remove any trace of the poison, as they work to identify the chemicals and potentially a culprit.

If a culprit is found and prosecuted, environmental vandalism can carry fines of more than $130,000.

Dozens of native trees, including at least one towering Norfolk pine, are dying after being illegally doused with poison along a beachfront walkway on Queensland's Sunshine Coast.

A 300-metre stretch along Dicky Beach in Caloundra was the target of the chemical attack, which has the potential to permanently contaminate the soil.

Sunshine Coast councillor Terry Landsberg said council teams had been scouring the area "with a fine-tooth comb" to remove any remaining traces of the poison.

"This is probably one of the largest in terms of poisoning that we've witnessed [on the Sunshine Coast].

"To see it on this scale is really distressing."

Cr Landsberg said the council was testing the samples collected from the area to determine the exact poison used, in the hopes of saving the affected trees.

"We can see that it's extremely aggressive".

The councillor declined to speculate about why anyone would want to poison a long line of beachfront trees.

"You can take your own assumptions in regards to why people do this on this scale," he said.

"We've got to make sure we respect the process before we start singling out any property owner or individual.

"We've got to follow due process and make sure we deal with it in an appropriate manner."

If a culprit is found and prosecuted, environmental vandalism can carry fines of more than $130,000.

Caloundra resident Chloe Christopher, 28, has lived in the area her entire life, and said she was hurt to see the damage done.

She said the area was usually "luscious" and dotted with flowers.

"It's sad to see because we live in such a beautiful part of the coast, so it's really sad to come past and see all of our beautiful plants dying," she said.

Dicky Beach resident Brittany Guy, with son, questioned why anyone would poison the same trees that make the area so beautiful and valuable. (ABC News: Owen Jacques)

Brittany Guy, who lives nearby, spends a lot of time in the area with her young son and said she was furious to learn trees had been poisoned.

"There's people paying millions and millions of dollars to live here for the environment that we live in and that nature we're around.

"I don't understand why they would do that."

The Sunshine Coast council is not the only one grappling with illegal destruction of trees and greenery.

In September, Noosa couple Heidi Meyer and Kim Carroll were ordered to replant almost 1,600 trees and pay court fees of almost $50,000 for illegally clearing their private land.

The cleared and subdivided land on Picture Point Crescent in Noosa Heads was listed for sale online for $25 million last year.

A Noosa council spokesman said he hoped the costs and orders would serve as a warning to others.
