A pretty uniform button
NSW National Parks and Wildlife Service
In 1967 the Fauna Protection Panel and the Reserves Branch of the Lands Department were amalgamated into this new service, under the Department of Lands, Industry and Environment. They study and conserve wildlife and land, map protected areas, and up-keep fire trails. The photo below is from the NSW State Archives of the first meeting of its staff. The buttons can be seen on the jackets.
