ABOUT 400 native forest sites would again be available to beekeepers if the Victorian Coalition won government.

The bee-pollination industry has long said lack of access to nectar-rich native forest sites - required to allow bees to rest and recover before and after pollinating crops - was killing the industry.

Beekeepers say the situation would eventually result in a lack of bees to pollinate fruit and vegetable crops, many of which are highly reliant on bee pollination.

The Coalition will today anounced it will reinstate all bee site licences cancelled in the past 20 years.

Opposition leader Ted Baillieu said the Coalition would "actively pursue" the expansion of the bee industry.

"We'll find additional sites and cut the bureaucratic red tape strangling the industry," Mr Baillieu said.

"We will maintain pressure on the Federal Government to ... keep the industry free of devastating pests such as varroa mite."

The Victorian Government had assessed only half the bee sites it had promised to by August this year, he said.
