State Government figures show that despite a commitment to reduce use of the poison, the amount distributed by permit jumped in the 2008-09 financial year.
Two-thirds was used by private forestry companies, including Gunns Ltd.
Heavy rains are tipped to increase demand by farmers.
Just under 1kg of 1080 was officially distributed.
The Tasmanian Conservation Trust said that was enough to kill tens of thousands of animals, mostly pademelons and Bennett’s wallabies.
“We fear the recent increase in 1080 use will continue and without a commitment from the State Government to effective alternatives, farmers and forestry companies may go back to relying on 1080 or another poison being developed, Feratox,” said TCT director Peter McGlone.
He said animals suffered a drawn-out death from 1080.
The information, which was released to the TCT, said that from November last year to August 19 this year 45 applications for 1080 crop protection permits were made, mostly for the state’s North-East. Three were rejected.
Wallabies and brush-tailed possums were the stated targets.
