A patch of Tasmanian forest where critically endangered swift parrots have been nesting being trashed by logging has shocked researchers.
Government owned business Sustainable Timber has logged the Tylers Hill area near Dover in the state's south in recent months.
Having visited the site to install anti-predator devices, Biologist Dejan Stojanovic was horrified by what he saw.
"On arrival just the whole patch of bush where these birds have nested for over 10 years of our monitoring has just gone."
He's pushing for laws to be changed because the logging was carried out legally.
