Based in Tasmania's Derwent Valley, Fiona Weaver's adventure tourism business trades on the reputation of Tasmania's pristine wilderness.
Nearby, logging operations knock down forests similar to the ones Ms Weaver's customers have come to experience.
She believes the two industries can no longer co-exist, and has added her voice to an open letter signed by 209 other businesses calling for Tasmania's native forest logging industry to end.
"The biggest drawcard, and the reason people are coming to Tasmania, is for their connection with big nature, our big trees, beautiful mountains and wilderness experiences," Ms Weaver said.
"When they're coming here and seeing so many huge native trees being brought out on log [trucks] running all through the night … and also the forestry burns, it just really provides the wrong message to our visitors."
Researchers recently discovered Tasmania has become not just carbon neutral, but carbon negative, due to the reduction of logging in the state over recent years — one of the first places on the planet to achieve the milestone.
Despite that, a new report finds Tasmania's native forest logging sector is the state's highest emitting industry.
Forest ecologist Jennifer Sanger said the emissions from native forest logging were usually masked by the way the figures were reported.
Tasmania's forest estate — which draws down significant amounts of carbon from the atmosphere — is included in the same category as logging emissions, with only a net figure reported.
Dr Sanger's report, in collaboration with The Wilderness Society and the Tasmanian Climate Collective, has found greenhouse gas emissions from native forest logging are equivalent to about 4.65 million tonnes of carbon each year.
That's similar to the annual emissions from 1.1 million cars, 258,000 homes, or 422,000 return flights to London.
"The emissions from forestry are actually quite huge," Dr Sanger said.
"Native forest logging is the number-one climate issue for Tasmania."
Dr Sanger's report, which has not been formally peer-reviewed, argues almost two-thirds of the carbon from a logged native forest is released into the atmosphere within two years — 30 per cent from slash burning, 10 per cent in mill waste, and 24 per cent from paper products with a short life span.
Some of the forest carbon has a much longer life span — 30 per cent is woody debris left onsite which breaks down over 50 years, while five per cent is stored long-term as engineered timber, and one per cent as sawn timber.
Dr Sanger said if Tasmania followed Victoria and Western Australia's lead and ended native forest logging, 75 million tonnes of carbon could be absorbed by the state's production forests by 2050.
She said that would be equivalent to taking every car off the road in Australia for a year, shutting down Australia's dirtiest power plant, Yallourn, eight years early, or converting 236,000 homes to solar.
Dr Sanger said focusing the timber industry on plantation forests instead would be more efficient and create less waste, and plantations on already cleared land would also act to draw down carbon before harvesting.
"If we protected our forests, especially the forests that are re-growing from previous logging, they're drawing down significant amounts of carbon from the atmosphere, and if we protect them that means the carbon is going to be stored long-term," Dr Sanger said.
"It's a really, really good climate solution for us."
The report's key findings were put to Sustainable Timber Tasmania.
STT's conservation and land management general manager Suzette Weeding said the state-owned company was working to mitigate and adapt to climate change risks posed by issues such as extreme weather.
Ms Weeding said STT's role included planting and growing trees, managing fires, pests and disease, ensuring wood can be used rather than other materials that require more energy to produce, and reducing timber imports from less sustainably managed forests.
