Logging in an environmentally significant old growth forest in Victoria will remain banned until the state government implements a host of measures to protect endangered species.

Victoria's Supreme Court has upheld the ban preventing logging at Brown Mountain in the state's far east under an injunction, while a number of surveys on endangered wildlife are carried out.

In a decision hailed as a victory by environmentalists, Justice Robert Osborn also ordered special protection zones and "habitat retention" areas be created at Brown Mountain, north of Orbost in East Gippsland before logging can start.

Anti-logging campaigners Environment East Gippsland took action in the Supreme Court last year to stop the state-owned timber agency VicForests logging at Brown Mountain.

Logging was due to start at the site last September but it was halted until the outcome of the Supreme Court trial, which took place in March.
