Native seeds to rehabilitate mine 

COAL & Allied is using the latest agricultural technology to plant a blend of native grass seeds over 80 hectares of rehabilitated mining land.

The seed mixes have been prepared with the same level of species diversity found in local endangered ecological communities.

The company's environmental services manager Andrew Speechly said early results for new understorey growth at the Hunter Valley Operations and Mount Thorley Warkworth mines were promising.

"Understorey species are an important component of healthy native vegetation communities but do not feature significantly in existing mine site rehabilitation," he said.

"The use of local native seed is necessary to return the land to as close as possible to its original state."

Specialist contractors work on the project.

"We've worked for up to a year on soil preparation in places with outcomes including naturally aerated soil, re-established soil microbes and contoured land conducive to water infiltration," said Tyrone Parrey of Parrey Pastoral Rehabilitation. "These outcomes lay a healthy foundation for native plants to establish and grow."
