The Kalan Rangers work within the Mt Croll Nature Reserve and the surrounding Aboriginal freehold land located in the Cape York Peninsula of north Queensland. This area consists of approximately 17,990 hectares of high quality ecosystems, of which 5,132 hectares is currently part of the National Reserve System as Nature Refuge under the Queensland Nature Conservation Act 1992.
A Conservation Agreement between the Toolka Land Trust and the Queensland Government to establish the Mt Croll Nature Refuge provides the framework for the ranger's land management plan.
The rangers implement management activities to help keep country healthy and protect cultural heritage. Work includes weed and feral animal control, fire and grazing management and specific activities identified in the Conservative Agreement.
