The call for the creation of new national parks including Barmah State Forest would be a key test of Victorian Premier John Brumby's conservation credentials, according to an environment group.

Victorian National Parks Association spokesman Nick Roberts said the Victorian Government must honour its key election promise to establish major new red gum national parks in the state's north.

Mr Roberts said the implementation of the new red gum parks was likely to be the most significant nature conservation proposal in the Brumby Government's current term.

"Victorians now expect the promise to be fully and quickly implemented," Mr Roberts said.

"After three years of independent investigation and extensive community consultation, the case for new parks is overwhelming and there are no excuses for delay in implementing VEAC's recommendations and delivering on the election commitment."

He said the logging industry was declining anyway with the prospect of a reduction in jobs from one third to one half.

"The VEAC report indicated that as far as commercial impact, logging represents only about 0.8 per cent of the economy."

Asked about the lack of an environmental flow figure in the latest report, Mr Roberts said the VEAC role in pressing for better environmental flows had largely been overtaken by state and federal government policy announcements.

"The Federal Government has committed to flows a lot higher than that (4000 Gl) and has already announced a $3 billion water buy-back scheme."

Mr Roberts said while environment groups were disappointed at the small reduction in total area of proposed parks from the draft report, they welcomed the bulk of the report's recommendations.
