An award-winning, internationally lichen scientist is set to lose his job managing the Tasmanian Herbarium, as the state government's job cuts hit the science sector.
Active Tasmania, public transport compliance and librarians are also set to go, but the public sector union says the extent of the cuts are still being "hidden".
The restructure plans are open for consultation for two weeks.
Scientific roles are among those that have been hit by Tasmania's public sector job losses.
The ABC understands around half of the team at the Tasmanian Herbarium have been told they will lose their jobs, including the director, internationally acclaimed lichen researcher Dr Gintaras Kantvilas.
Dr Kantvilas won the Premier's STEM Researcher of the Year Award last year.
The Tasmanian Herbarium holds more than 312,000 preserved plant specimens and is responsible for developing, maintaining and managing Tasmania's official botanical collections.
A total of 150 jobs are being axed as part of the state government's Building Tasmania restructure. Already identified are 111 voluntary redundancies.
Independent MP Meg Webb said the targeting of areas such as the Herbarium for job cuts was indefensible.
The ABC understands a range of services have been affected by cuts, including public transport compliance and librarians at the Tasmanian Museum and Art Gallery and the Geosciences Library.
The Community and Public Sector Union said it understood Active Tasmania, as well as Antarctic science and tech divisions, had been devastated.
In a statement yesterday, Building Tasmania acting secretary Shane Gregory said the process had been "highly complex".
