The awards, which open this week, are an integral mechanism to promote innovative practices that foster improvements in productivity, competitiveness and sustainability of Australia's primary industries.

"For more than two decades, the National Landcare Awards have celebrated Landcare and Coastcare achievements and the partnership between communities and the Australian, state and territory governments," Mr Joyce said.

"Many groups contribute to Australia's land management decisions, and Landcare groups lead the way, with the largest percentage of farmers involved."

Mr Joyce said the awards were heavily supported by Tasmania's farming community.

"Over three-quarters of all farmers support the Landcare movement and with more than 6000 Landcare groups and 100,000 volunteers, Australians understand how important it is to get natural resource management right.

"The awards are an opportunity to give national recognition to the tireless efforts of farmers, community groups, councils, school groups and businesses that volunteer their time to the management of our valuable natural resources."

The awards feature nine national categories covering individual landcarers, sustainable farming, Junior Landcare, and Coastcare, among others.

"I encourage those active in Landcare initiatives to put their nominations forward to recognise the invaluable contributions of volunteers," Mr Joyce said.

Entries for the 2015 State and Territory Landcare Awards are open until May 31.
