Unique opportunity to reduce coverage of giant rush

The ongoing low river levels in the Murray River have provided a unique opportunity for Forests NSW to treat some areas of the Moira Lake and Reed Beds wetlands to reduce the coverage of giant rush (Juncus ingens).

Forests NSW regional ecologist/hydrologist, Gary Miller, said that the species, while native, had become locally invasive.

“Historical records of these areas show that giant rush would have occupied only a small amount of these wetlands,” he said.

“As a result, other plants have been crowded out reducing the natural biodiversty and available breeding areas for waterbirds.”

Mr Miller said Moira Lake and Reed Beds wetlands are part of the Barmah-Millewa Forests Icon Site, which is part of the Living Murray Program.

“Burning is one of a range of tools we use to rehabilitate these wetland areas, increase plant diversity and increase the foraging habitat for a range of waterbird species,” he said.

A team of Forests NSW staff from Mathoura and Deniliquin will be undertaking the burns in specific areas throughout Moira Lake and Reed Beds wetlands when suitable conditions occur during the next two weeks.

Operations Forester Mick Lalor said that the burns would occur in isolated patches and control lines would be established to protect sensitive breeding areas and fringing red gums.

Smoke Warning signs will be erected on the Cobb Highway, Picnic Point Road and Forest entrances, although the burns are not expected to interfere with local traffic.

As Part of the Living Murray Program, Mr Miller said other substantial infrastructure works were also currently being planned to provide a more natural wetting and drying cycle for these wetlands.
